6 Testpmd Runtime Functions
7 =========================
9 Where the testpmd application is started in interactive mode, (``-i|--interactive``),
10 it displays a prompt that can be used to start and stop forwarding,
11 configure the application, display statistics (including the extended NIC
12 statistics aka xstats) , set the Flow Director and other tasks::
16 The testpmd prompt has some, limited, readline support.
17 Common bash command-line functions such as ``Ctrl+a`` and ``Ctrl+e`` to go to the start and end of the prompt line are supported
18 as well as access to the command history via the up-arrow.
20 There is also support for tab completion.
21 If you type a partial command and hit ``<TAB>`` you get a list of the available completions:
23 .. code-block:: console
25 testpmd> show port <TAB>
27 info [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|dcb_tc|cap X
28 info [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|dcb_tc|cap all
29 stats [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|dcb_tc|cap X
30 stats [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|dcb_tc|cap all
36 Some examples in this document are too long to fit on one line are shown wrapped at `"\\"` for display purposes::
38 testpmd> set flow_ctrl rx (on|off) tx (on|off) (high_water) (low_water) \
39 (pause_time) (send_xon) (port_id)
41 In the real ``testpmd>`` prompt these commands should be on a single line.
46 The testpmd has on-line help for the functions that are available at runtime.
47 These are divided into sections and can be accessed using help, help section or help all:
49 .. code-block:: console
53 help control : Start and stop forwarding.
54 help display : Displaying port, stats and config information.
55 help config : Configuration information.
56 help ports : Configuring ports.
57 help registers : Reading and setting port registers.
58 help filters : Filters configuration help.
59 help all : All of the above sections.
62 Command File Functions
63 ----------------------
65 To facilitate loading large number of commands or to avoid cutting and pasting where not
66 practical or possible testpmd supports alternative methods for executing commands.
68 * If started with the ``--cmdline-file=FILENAME`` command line argument testpmd
69 will execute all CLI commands contained within the file immediately before
70 starting packet forwarding or entering interactive mode.
72 .. code-block:: console
74 ./dpdk-testpmd -n4 -r2 ... -- -i --cmdline-file=/home/ubuntu/flow-create-commands.txt
75 Interactive-mode selected

105 Flow rule #498 created
106 Flow rule #499 created
107 Read all CLI commands from /home/ubuntu/flow-create-commands.txt
111 In all cases output from any included command will be displayed as standard output.
112 Execution will continue until the end of the file is reached regardless of
113 whether any errors occur. The end user must examine the output to determine if
114 any failures occurred.
123 Start packet forwarding with current configuration::
130 Start packet forwarding with current configuration after sending specified number of bursts of packets::
132 testpmd> start tx_first (""|burst_num)
134 The default burst number is 1 when ``burst_num`` not presented.
139 Stop packet forwarding, and display accumulated statistics::
154 The functions in the following sections are used to display information about the
155 testpmd configuration or the NIC status.
160 Display information for a given port or all ports::
162 testpmd> show port (info|summary|stats|xstats|fdir|dcb_tc|cap) (port_id|all)
164 The available information categories are:
166 * ``info``: General port information such as MAC address.

222 testpmd> show port (port_id) (module_eeprom|eeprom)
227 Display the rss redirection table entry indicated by masks on port X::
229 testpmd> show port (port_id) rss reta (size) (mask0, mask1...)
231 size is used to indicate the hardware supported reta size
236 Display the RSS hash functions and RSS hash key of a port::
238 testpmd> show port (port_id) rss-hash [key]
243 Clear the port statistics and forward engine statistics for a given port or for all ports::
245 testpmd> clear port (info|stats|xstats|fdir) (port_id|all)
249 testpmd> clear port stats all
254 Display information for a given port's RX/TX queue::
256 testpmd> show (rxq|txq) info (port_id) (queue_id)
258 show desc status(rxq|txq)
259 ~~~~~~~~~~~~~~~~~~~~~~~~~
261 Display information for a given port's RX/TX descriptor status::

308 TX threshold registers: pthresh=36 hthresh=0 wthresh=0
309 TX RS bit threshold=0 - TXQ flags=0x0
314 Set the packet forwarding mode::
316 testpmd> set fwd (io|mac|macswap|flowgen| \
317 rxonly|txonly|csum|icmpecho|noisy|5tswap|shared-rxq) (""|retry)
319 ``retry`` can be specified for forwarding engines except ``rx_only``.
321 The available information categories are:
323 * ``io``: Forwards packets "as-is" in I/O mode.
324 This is the fastest possible forwarding operation as it does not access packets data.
325 This is the default mode.
327 * ``mac``: Changes the source and the destination Ethernet addresses of packets before forwarding them.
328 Default application behavior is to set source Ethernet address to that of the transmitting interface, and destination
329 address to a dummy value (set during init). The user may specify a target destination Ethernet address via the 'eth-peer' or
330 'eth-peers-configfile' command-line options. It is not currently possible to specify a specific source Ethernet address.
332 * ``macswap``: MAC swap forwarding mode.
333 Swaps the source and the destination Ethernet addresses of packets before forwarding them.
335 * ``flowgen``: Multi-flow generation mode.
336 Originates a number of flows (with varying destination IP addresses), and terminate receive traffic.
338 * ``rxonly``: Receives packets but doesn't transmit them.
340 * ``txonly``: Generates and transmits packets without receiving any.
342 * ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet.
344 * ``icmpecho``: Receives a burst of packets, lookup for ICMP echo requests and, if any, send back ICMP echo replies.
346 * ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX.
348 * ``noisy``: Noisy neighbor simulation.
349 Simulate more realistic behavior of a guest machine engaged in receiving
350 and sending packets performing Virtual Network Function (VNF).
352 * ``5tswap``: Swap the source and destination of L2,L3,L4 if they exist.
354 L2 swaps the source address and destination address of Ethernet, as same as ``macswap``.
356 L3 swaps the source address and destination address of IP (v4 and v6).
358 L4 swaps the source port and destination port of transport layer (TCP and UDP).
360 * ``shared-rxq``: Receive only for shared Rx queue.
361 Resolve packet source port from mbuf and update stream statistics accordingly.
365 testpmd> set fwd rxonly
367 Set rxonly packet forwarding mode
373 When running, forwarding engines maintain statistics from the time they have been started.
374 Example for the io forwarding engine, with some packet drops on the tx side::
376 testpmd> show fwd stats all
378 ------- Forward Stats for RX Port= 0/Queue= 0 -> TX Port= 1/Queue= 0 -------

651 Configuration Functions
652 -----------------------
654 The testpmd application can be configured from the runtime as well as from the command-line.
656 This section details the available configuration functions that are available.
660 Configuration changes only become active when forwarding is started/restarted.
665 Reset forwarding to the default configuration::
672 Set the debug verbosity level::
674 testpmd> set verbose (level)
676 Available levels are as following:
678 * ``0`` silent except for error.
679 * ``1`` fully verbose except for Tx packets.
680 * ``2`` fully verbose except for Rx packets.
681 * ``> 2`` fully verbose.
686 Set the log level for a log type::
688 testpmd> set log global|(type) (level)
692 * ``type`` is the log name.
694 * ``level`` is the log level.
696 For example, to change the global log level::
698 testpmd> set log global (level)
700 Regexes can also be used for type. To change log level of user1, user2 and user3::
702 testpmd> set log user[1-3] (level)
707 Set the number of ports used by the application:
711 This is equivalent to the ``--nb-ports`` command-line option.
716 Set the number of cores used by the application::
718 testpmd> set nbcore (num)
720 This is equivalent to the ``--nb-cores`` command-line option.
724 The number of cores used must not be greater than number of ports used multiplied by the number of queues per port.
729 Set the forwarding cores hexadecimal mask::
731 testpmd> set coremask (mask)
733 This is equivalent to the ``--coremask`` command-line option.
737 The main lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
742 Set the forwarding ports hexadecimal mask::
744 testpmd> set portmask (mask)
746 This is equivalent to the ``--portmask`` command-line option.
748 set record-core-cycles
749 ~~~~~~~~~~~~~~~~~~~~~~
751 Set the recording of CPU cycles::
753 testpmd> set record-core-cycles (on|off)
757 * ``on`` enables measurement of CPU cycles per packet.
759 * ``off`` disables measurement of CPU cycles per packet.
761 This is equivalent to the ``--record-core-cycles command-line`` option.
763 set record-burst-stats
764 ~~~~~~~~~~~~~~~~~~~~~~
766 Set the displaying of RX and TX bursts::
768 testpmd> set record-burst-stats (on|off)
772 * ``on`` enables display of RX and TX bursts.
774 * ``off`` disables display of RX and TX bursts.
776 This is equivalent to the ``--record-burst-stats command-line`` option.
781 Set number of packets per burst::
783 testpmd> set burst (num)
785 This is equivalent to the ``--burst command-line`` option.
787 When retry is enabled, the transmit delay time and number of retries can also be set::
789 testpmd> set burst tx delay (microseconds) retry (num)
794 Set the offsets of segments relating to the data buffer beginning on receiving
795 if split feature is engaged. Affects only the queues configured with split
796 offloads (currently BUFFER_SPLIT is supported only).
798 testpmd> set rxoffs (x[,y]*)
800 Where x[,y]* represents a CSV list of values, without white space. If the list
801 of offsets is shorter than the list of segments the zero offsets will be used
802 for the remaining segments.
807 Set the length of segments to scatter packets on receiving if split
808 feature is engaged. Affects only the queues configured with split offloads
809 (currently BUFFER_SPLIT is supported only). Optionally the multiple memory
810 pools can be specified with --mbuf-size command line parameter and the mbufs
811 to receive will be allocated sequentially from these extra memory pools (the
812 mbuf for the first segment is allocated from the first pool, the second one
813 from the second pool, and so on, if segment number is greater then pool's the
814 mbuf for remaining segments will be allocated from the last valid pool).
816 testpmd> set rxpkts (x[,y]*)
818 Where x[,y]* represents a CSV list of values, without white space. Zero value
819 means to use the corresponding memory pool data buffer size.
824 Set the length of each segment of the TX-ONLY packets or length of packet for FLOWGEN mode::
826 testpmd> set txpkts (x[,y]*)
828 Where x[,y]* represents a CSV list of values, without white space.
833 Configure the timing burst pattern for Tx only mode. This command enables
834 the packet send scheduling on dynamic timestamp mbuf field and configures
835 timing pattern in Tx only mode. In this mode, if scheduling is enabled
836 application provides timestamps in the packets being sent. It is possible
837 to configure delay (in unspecified device clock units) between bursts
838 and between the packets within the burst::
840 testpmd> set txtimes (inter),(intra)
844 * ``inter`` is the delay between the bursts in the device clock units.
845 If ``intra`` is zero, this is the time between the beginnings of the
846 first packets in the neighbour bursts, if ``intra`` is not zero,
847 ``inter`` specifies the time between the beginning of the first packet
848 of the current burst and the beginning of the last packet of the
849 previous burst. If ``inter`` parameter is zero the send scheduling
850 on timestamps is disabled (default).
852 * ``intra`` is the delay between the packets within the burst specified
853 in the device clock units. The number of packets in the burst is defined
854 by regular burst setting. If ``intra`` parameter is zero no timestamps
855 provided in the packets excepting the first one in the burst.
857 As the result the bursts of packet will be transmitted with specific
858 delays between the packets within the burst and specific delay between
859 the bursts. The rte_eth_read_clock() must be supported by the device(s)
860 and is supposed to be engaged to get the current device clock value
861 and provide the reference for the timestamps. If there is no supported
862 rte_eth_read_clock() there will be no send scheduling provided on the port.
867 Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes::
869 testpmd> set txsplit (off|on|rand)
873 * ``off`` disable packet copy & split for CSUM mode.
875 * ``on`` split outgoing packet into multiple segments. Size of each segment
876 and number of segments per packet is determined by ``set txpkts`` command
879 * ``rand`` same as 'on', but number of segments per each packet is a random value between 1 and total number of segments.
884 Set the list of forwarding cores::
886 testpmd> set corelist (x[,y]*)
888 For example, to change the forwarding cores:
890 .. code-block:: console
892 testpmd> set corelist 3,1
893 testpmd> show config fwd
895 io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled
896 Logical Core 3 (socket 0) forwards packets on 1 streams:
897 RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
898 Logical Core 1 (socket 0) forwards packets on 1 streams:
899 RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
903 The cores are used in the same order as specified on the command line.
908 Set the list of forwarding ports::
910 testpmd> set portlist (x[,y]*)
912 For example, to change the port forwarding:
914 .. code-block:: console
916 testpmd> set portlist 0,2,1,3
917 testpmd> show config fwd
919 io packet forwarding - ports=4 - cores=1 - streams=4
920 Logical Core 3 (socket 0) forwards packets on 4 streams:
921 RX P=0/Q=0 (socket 0) -> TX P=2/Q=0 (socket 0) peer=02:00:00:00:00:01

1059 Add a VLAN ID, or all identifiers, to the set of VLAN identifiers filtered by port ID::
1061 testpmd> rx_vlan add (vlan_id|all) (port_id)
1065 VLAN filter must be set on that port. VLAN ID < 4096.
1066 Depending on the NIC used, number of vlan_ids may be limited to the maximum entries

1138 transmitting a packet using the ``csum`` forwarding engine::
1140 testpmd> csum set (ip|udp|tcp|sctp|outer-ip|outer-udp) (hw|sw) (port_id)
1144 * ``ip|udp|tcp|sctp`` always relate to the inner layer.
1146 * ``outer-ip`` relates to the outer IP layer (only for IPv4) in the case where the packet is recognized
1147 as a tunnel packet by the forwarding engine (geneve, gre, gtp, ipip, vxlan and vxlan-gpe are
1148 supported). See also the ``csum parse-tunnel`` command.
1150 * ``outer-udp`` relates to the outer UDP layer in the case where the packet is recognized
1151 as a tunnel packet by the forwarding engine (geneve, gtp, vxlan and vxlan-gpe are
1152 supported). See also the ``csum parse-tunnel`` command.
1156 Check the NIC Datasheet for hardware limits.

1179 Flush all queue region related configuration on a port::
1181 testpmd> set port (port_id) queue-region flush (on|off)
1185 * ``on``: is just an enable function which server for other configuration,
1186 it is for all configuration about queue region from up layer,
1187 at first will only keep in DPDK software stored in driver,
1188 only after "flush on", it commit all configuration to HW.
1190 * ``"off``: is just clean all configuration about queue region just now,
1191 and restore all to DPDK i40e driver default config when start up.
1193 Show all queue region related configuration info on a port::
1195 testpmd> show port (port_id) queue-region
1199 Queue region only support on PF by now, so these command is
1200 only for configuration of queue region on PF port.
1205 Define how tunneled packets should be handled by the csum forward
1208 testpmd> csum parse-tunnel (on|off) (tx_port_id)
1210 If enabled, the csum forward engine will try to recognize supported
1211 tunnel headers (geneve, gtp, gre, ipip, vxlan, vxlan-gpe).
1213 If disabled, treat tunnel packets as non-tunneled packets (a inner
1214 header is handled as a packet payload).
1218 The port argument is the TX port like in the ``csum set`` command.
1222 Consider a packet in packet like the following::
1224 eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in
1226 * If parse-tunnel is enabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
1227 command relate to the inner headers (here ``ipv4_in`` and ``tcp_in``), and the
1228 ``outer-ip|outer-udp`` parameter relates to the outer headers (here ``ipv4_out`` and ``udp_out``).
1230 * If parse-tunnel is disabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
1231 command relate to the outer headers, here ``ipv4_out`` and ``udp_out``.

1263 testpmd> tunnel_tso set (tso_segsz) (port_id)
1268 Display the status of tunneled TCP Segmentation Offload for a port::
1270 testpmd> tunnel_tso show (port_id)
1275 Enable or disable GRO in ``csum`` forwarding engine::
1277 testpmd> set port <port_id> gro on|off
1279 If enabled, the csum forwarding engine will perform GRO on the TCP/IPv4
1280 packets received from the given port.
1282 If disabled, packets received from the given port won't be performed
1283 GRO. By default, GRO is disabled for all ports.
1287 When enable GRO for a port, TCP/IPv4 packets received from the port
1288 will be performed GRO. After GRO, all merged packets have bad
1289 checksums, since the GRO library doesn't re-calculate checksums for
1290 the merged packets. Therefore, if users want the merged packets to
1291 have correct checksums, please select HW IP checksum calculation and
1292 HW TCP checksum calculation for the port which the merged packets are
1298 Display GRO configuration for a given port::
1300 testpmd> show port <port_id> gro
1305 Set the cycle to flush the GROed packets from reassembly tables::
1307 testpmd> set gro flush <cycles>
1309 When enable GRO, the csum forwarding engine performs GRO on received
1310 packets, and the GROed packets are stored in reassembly tables. Users
1311 can use this command to determine when the GROed packets are flushed
1312 from the reassembly tables.
1314 The ``cycles`` is measured in GRO operation times. The csum forwarding
1315 engine flushes the GROed packets from the tables every ``cycles`` GRO
1318 By default, the value of ``cycles`` is 1, which means flush GROed packets
1319 from the reassembly tables as soon as one GRO operation finishes. The value
1320 of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``.
1322 Please note that the large value of ``cycles`` may cause the poor TCP/IP
1323 stack performance. Because the GROed packets are delayed to arrive the
1324 stack, thus causing more duplicated ACKs and TCP retransmissions.
1329 Toggle per-port GSO support in ``csum`` forwarding engine::
1331 testpmd> set port <port_id> gso on|off
1333 If enabled, the csum forwarding engine will perform GSO on supported IPv4
1334 packets, transmitted on the given port.
1336 If disabled, packets transmitted on the given port will not undergo GSO.
1337 By default, GSO is disabled for all ports.
1341 When GSO is enabled on a port, supported IPv4 packets transmitted on that
1342 port undergo GSO. Afterwards, the segmented packets are represented by
1343 multi-segment mbufs; however, the csum forwarding engine doesn't calculation
1344 of checksums for GSO'd segments in SW. As a result, if users want correct
1345 checksums in GSO segments, they should enable HW checksum calculation for
1348 For example, HW checksum calculation for VxLAN GSO'd packets may be enabled
1349 by setting the following options in the csum forwarding engine:
1351 testpmd> csum set outer_ip hw <port_id>
1353 testpmd> csum set ip hw <port_id>
1355 testpmd> csum set tcp hw <port_id>
1357 UDP GSO is the same as IP fragmentation, which treats the UDP header
1358 as the payload and does not modify it during segmentation. That is,
1359 after UDP GSO, only the first output fragment has the original UDP
1360 header. Therefore, users need to enable HW IP checksum calculation
1361 and SW UDP checksum calculation for GSO-enabled ports, if they want
1362 correct checksums for UDP/IPv4 packets.
1367 Set the maximum GSO segment size (measured in bytes), which includes the
1368 packet header and the packet payload for GSO-enabled ports (global)::
1370 testpmd> set gso segsz <length>

2043 The following sections show functions for configuring ports.
2047 Port configuration changes only become active when forwarding is started/restarted.
2052 Attach a port specified by pci address or virtual device args::
2054 testpmd> port attach (identifier)
2056 To attach a new pci device, the device should be recognized by kernel first.
2057 Then it should be moved under DPDK management.
2058 Finally the port can be attached to testpmd.
2060 For example, to move a pci device using ixgbe under DPDK management:
2062 .. code-block:: console
2064 # Check the status of the available devices.
2065 ./usertools/dpdk-devbind.py --status
2067 Network devices using DPDK-compatible driver
2068 ============================================
2071 Network devices using kernel driver
2072 ===================================
2073 0000:0a:00.0 '82599ES 10-Gigabit' if=eth2 drv=ixgbe unused=
2076 # Bind the device to igb_uio.
2077 sudo ./usertools/dpdk-devbind.py -b igb_uio 0000:0a:00.0
2080 # Recheck the status of the devices.
2081 ./usertools/dpdk-devbind.py --status
2082 Network devices using DPDK-compatible driver
2083 ============================================
2084 0000:0a:00.0 '82599ES 10-Gigabit' drv=igb_uio unused=
2086 To attach a port created by virtual device, above steps are not needed.
2088 For example, to attach a port whose pci address is 0000:0a:00.0.
2090 .. code-block:: console
2092 testpmd> port attach 0000:0a:00.0
2093 Attaching a new port...
2094 EAL: PCI device 0000:0a:00.0 on NUMA socket -1
2095 EAL: probe driver: 8086:10fb rte_ixgbe_pmd
2096 EAL: PCI memory mapped at 0x7f83bfa00000
2097 EAL: PCI memory mapped at 0x7f83bfa80000
2098 PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
2099 PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
2100 Port 0 is attached. Now total ports is 1
2103 For example, to attach a port created by pcap PMD.
2105 .. code-block:: console
2107 testpmd> port attach net_pcap0
2108 Attaching a new port...
2109 PMD: Initializing pmd_pcap for net_pcap0
2110 PMD: Creating pcap-backed ethdev on numa socket 0
2111 Port 0 is attached. Now total ports is 1
2114 In this case, identifier is ``net_pcap0``.
2115 This identifier format is the same as ``--vdev`` format of DPDK applications.
2117 For example, to re-attach a bonded port which has been previously detached,
2118 the mode and slave parameters must be given.
2120 .. code-block:: console
2122 testpmd> port attach net_bond_0,mode=0,slave=1
2123 Attaching a new port...
2124 EAL: Initializing pmd_bond for net_bond_0
2125 EAL: Create bonded device net_bond_0 on port 0 in mode 0 on socket 0.
2126 Port 0 is attached. Now total ports is 1
2133 Detach a specific port::
2135 testpmd> port detach (port_id)
2137 Before detaching a port, the port should be stopped and closed.
2139 For example, to detach a pci device port 0.
2141 .. code-block:: console
2143 testpmd> port stop 0
2146 testpmd> port close 0
2150 testpmd> port detach 0
2152 EAL: PCI device 0000:0a:00.0 on NUMA socket -1
2153 EAL: remove driver: 8086:10fb rte_ixgbe_pmd
2154 EAL: PCI memory unmapped at 0x7f83bfa00000
2155 EAL: PCI memory unmapped at 0x7f83bfa80000
2159 For example, to detach a virtual device port 0.
2161 .. code-block:: console
2163 testpmd> port stop 0
2166 testpmd> port close 0
2170 testpmd> port detach 0
2172 PMD: Closing pcap ethdev on numa socket 0
2173 Port 'net_pcap0' is detached. Now total ports is 0
2176 To remove a pci device completely from the system, first detach the port from testpmd.
2177 Then the device should be moved under kernel management.
2178 Finally the device can be removed using kernel pci hotplug functionality.
2180 For example, to move a pci device under kernel management:
2182 .. code-block:: console
2184 sudo ./usertools/dpdk-devbind.py -b ixgbe 0000:0a:00.0
2186 ./usertools/dpdk-devbind.py --status
2188 Network devices using DPDK-compatible driver
2189 ============================================
2192 Network devices using kernel driver
2193 ===================================
2194 0000:0a:00.0 '82599ES 10-Gigabit' if=eth2 drv=ixgbe unused=igb_uio
2196 To remove a port created by a virtual device, above steps are not needed.
2201 Start all ports or a specific port::
2203 testpmd> port start (port_id|all)
2208 Stop all ports or a specific port::
2210 testpmd> port stop (port_id|all)
2215 Close all ports or a specific port::
2217 testpmd> port close (port_id|all)

2313 RSS is on by default.
2315 The ``all`` option is equivalent to eth|vlan|ip|tcp|udp|sctp|ether|l2tpv3|esp|ah|pfcp.
2317 The ``default`` option enables all supported RSS types reported by device info.
2319 The ``none`` option is equivalent to the ``--disable-rss`` command-line option.

2456 port cleanup txq mbufs
2457 ~~~~~~~~~~~~~~~~~~~~~~
2459 To cleanup txq mbufs currently cached by driver::
2461 testpmd> port cleanup (port_id) txq (queue_id) (free_cnt)
2463 If the value of ``free_cnt`` is 0, driver should free all cached mbufs.
2468 The following sections show functions for device operations.
2473 Detach a device specified by pci address or virtual device args::
2475 testpmd> device detach (identifier)
2477 Before detaching a device associated with ports, the ports should be stopped and closed.
2479 For example, to detach a pci device whose address is 0002:03:00.0.
2481 .. code-block:: console
2483 testpmd> device detach 0002:03:00.0
2484 Removing a device...
2485 Port 1 is now closed
2486 EAL: Releasing pci mapped resource for 0002:03:00.0
2487 EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218a050000
2488 EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218c050000
2489 Device 0002:03:00.0 is detached
2490 Now total ports is 1
2492 For example, to detach a port created by pcap PMD.
2494 .. code-block:: console
2496 testpmd> device detach net_pcap0
2497 Removing a device...
2498 Port 0 is now closed
2499 Device net_pcap0 is detached
2500 Now total ports is 0
2503 In this case, identifier is ``net_pcap0``.
2504 This identifier format is the same as ``--vdev`` format of DPDK applications.
2506 Link Bonding Functions
2507 ----------------------
2509 The Link Bonding functions make it possible to dynamically create and
2510 manage link bonding devices from within testpmd interactive prompt.
2512 create bonded device
2513 ~~~~~~~~~~~~~~~~~~~~
2515 Create a new bonding device::
2517 testpmd> create bonded device (mode) (socket)
2519 For example, to create a bonded device in mode 1 on socket 0::
2521 testpmd> create bonded device 1 0
2522 created new bonded device (port X)
2527 Adds Ethernet device to a Link Bonding device::
2529 testpmd> add bonding slave (slave id) (port id)
2531 For example, to add Ethernet device (port 6) to a Link Bonding device (port 10)::
2533 testpmd> add bonding slave 6 10
2536 remove bonding slave
2537 ~~~~~~~~~~~~~~~~~~~~
2539 Removes an Ethernet slave device from a Link Bonding device::
2541 testpmd> remove bonding slave (slave id) (port id)
2543 For example, to remove Ethernet slave device (port 6) to a Link Bonding device (port 10)::
2545 testpmd> remove bonding slave 6 10
2550 Set the Link Bonding mode of a Link Bonding device::

2561 Set an Ethernet slave device as the primary device on a Link Bonding device::
2563 testpmd> set bonding primary (slave id) (port id)
2565 For example, to set the Ethernet slave device (port 6) as the primary port of a Link Bonding device (port 10)::
2567 testpmd> set bonding primary 6 10
2572 Set the MAC address of a Link Bonding device::
2574 testpmd> set bonding mac (port id) (mac)
2576 For example, to set the MAC address of a Link Bonding device (port 10) to 00:00:00:00:00:01::

2593 ~~~~~~~~~~~~~~~~~~~~~~
2595 Set the link status monitoring polling period in milliseconds for a bonding device.
2597 This adds support for PMD slave devices which do not support link status interrupts.
2598 When the mon_period is set to a value greater than 0 then all PMD's which do not support
2599 link status ISR will be queried every polling interval to check if their link status has changed::
2601 testpmd> set bonding mon_period (port_id) (value)
2603 For example, to set the link status monitoring polling period of bonded device (port 5) to 150ms::

3307 Flow rules management
3308 ---------------------
3310 Control of the generic flow API (*rte_flow*) is fully exposed through the
3311 ``flow`` command (validation, creation, destruction, queries and operation
3314 Considering *rte_flow* overlaps with all `Filter Functions`_, using both
3315 features simultaneously may cause undefined side-effects and is therefore
3321 Because the ``flow`` command uses dynamic tokens to handle the large number
3322 of possible flow rules combinations, its behavior differs slightly from
3323 other commands, in particular:
3325 - Pressing *?* or the *<tab>* key displays contextual help for the current
3326 token, not that of the entire command.
3328 - Optional and repeated parameters are supported (provided they are listed
3329 in the contextual help).
3331 The first parameter stands for the operation mode. Possible operations and
3332 their general syntax are described below. They are covered in detail in the
3335 - Check whether a flow rule can be created::
3337 flow validate {port_id}
3338 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3339 pattern {item} [/ {item} [...]] / end
3340 actions {action} [/ {action} [...]] / end
3342 - Create a flow rule::
3344 flow create {port_id}
3345 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3346 pattern {item} [/ {item} [...]] / end
3347 actions {action} [/ {action} [...]] / end
3349 - Destroy specific flow rules::
3351 flow destroy {port_id} rule {rule_id} [...]
3353 - Destroy all flow rules::
3355 flow flush {port_id}
3357 - Query an existing flow rule::
3359 flow query {port_id} {rule_id} {action}
3361 - List existing flow rules sorted by priority, filtered by group
3364 flow list {port_id} [group {group_id}] [...]
3366 - Restrict ingress traffic to the defined flow rules::
3368 flow isolate {port_id} {boolean}
3370 - Dump internal representation information of all flows in hardware::
3372 flow dump {port_id} all {output_file}
3376 flow dump {port_id} rule {rule_id} {output_file}
3378 - List and destroy aged flow rules::
3380 flow aged {port_id} [destroy]
3382 - Tunnel offload - create a tunnel stub::
3384 flow tunnel create {port_id} type {tunnel_type}
3386 - Tunnel offload - destroy a tunnel stub::
3388 flow tunnel destroy {port_id} id {tunnel_id}
3390 - Tunnel offload - list port tunnel stubs::
3392 flow tunnel list {port_id}
3394 Creating a tunnel stub for offload
3395 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3397 ``flow tunnel create`` setup a tunnel stub for tunnel offload flow rules::
3399 flow tunnel create {port_id} type {tunnel_type}
3401 If successful, it will return a tunnel stub ID usable with other commands::
3403 port [...]: flow tunnel #[...] type [...]
3405 Tunnel stub ID is relative to a port.
3407 Destroying tunnel offload stub
3408 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3410 ``flow tunnel destroy`` destroy port tunnel stub::
3412 flow tunnel destroy {port_id} id {tunnel_id}
3414 Listing tunnel offload stubs
3415 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3417 ``flow tunnel list`` list port tunnel offload stubs::
3419 flow tunnel list {port_id}
3421 Validating flow rules
3422 ~~~~~~~~~~~~~~~~~~~~~
3424 ``flow validate`` reports whether a flow rule would be accepted by the
3425 underlying device in its current state but stops short of creating it. It is
3426 bound to ``rte_flow_validate()``::
3428 flow validate {port_id}
3429 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3430 pattern {item} [/ {item} [...]] / end
3431 actions {action} [/ {action} [...]] / end
3433 If successful, it will show::
3437 Otherwise it will show an error message of the form::
3439 Caught error type [...] ([...]): [...]
3441 This command uses the same parameters as ``flow create``, their format is
3442 described in `Creating flow rules`_.
3444 Check whether redirecting any Ethernet packet received on port 0 to RX queue
3445 index 6 is supported::
3447 testpmd> flow validate 0 ingress pattern eth / end
3448 actions queue index 6 / end
3452 Port 0 does not support TCPv6 rules::
3454 testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
3456 Caught error type 9 (specific pattern item): Invalid argument
3462 ``flow create`` validates and creates the specified flow rule. It is bound
3463 to ``rte_flow_create()``::
3465 flow create {port_id}
3466 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3467 [tunnel_set {tunnel_id}] [tunnel_match {tunnel_id}]
3468 pattern {item} [/ {item} [...]] / end
3469 actions {action} [/ {action} [...]] / end
3471 If successful, it will return a flow rule ID usable with other commands::
3473 Flow rule #[...] created
3475 Otherwise it will show an error message of the form::
3477 Caught error type [...] ([...]): [...]
3479 Parameters describe in the following order:
3481 - Attributes (*group*, *priority*, *ingress*, *egress*, *transfer* tokens).
3482 - Tunnel offload specification (tunnel_set, tunnel_match)
3483 - A matching pattern, starting with the *pattern* token and terminated by an
3485 - Actions, starting with the *actions* token and terminated by an *end*
3488 These translate directly to *rte_flow* objects provided as-is to the
3489 underlying functions.
3491 The shortest valid definition only comprises mandatory tokens::
3493 testpmd> flow create 0 pattern end actions end
3495 Note that PMDs may refuse rules that essentially do nothing such as this
3498 **All unspecified object values are automatically initialized to 0.**
3503 These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
3504 specified before the ``pattern`` token.
3506 - ``group {group id}``: priority group.
3507 - ``priority {level}``: priority level within group.
3508 - ``ingress``: rule applies to ingress traffic.
3509 - ``egress``: rule applies to egress traffic.
3510 - ``transfer``: apply rule directly to endpoints found in pattern.
3512 Please note that use of ``transfer`` attribute requires that the flow and
3513 its indirect components be managed via so-called ``transfer`` proxy port.
3514 See `show flow transfer proxy port ID for the given port`_ for details.
3516 Each instance of an attribute specified several times overrides the previous
3517 value as shown below (group 4 is used)::
3519 testpmd> flow create 0 group 42 group 24 group 4 [...]
3521 Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
3523 While not specifying a direction is an error, some rules may allow both
3526 Most rules affect RX therefore contain the ``ingress`` token::
3528 testpmd> flow create 0 ingress pattern [...]
3533 Indicate tunnel offload rule type
3535 - ``tunnel_set {tunnel_id}``: mark rule as tunnel offload decap_set type.
3536 - ``tunnel_match {tunnel_id}``: mark rule as tunnel offload match type.
3541 A matching pattern starts after the ``pattern`` token. It is made of pattern
3542 items and is terminated by a mandatory ``end`` item.
3544 Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
3545 rte_flow_item_type``).
3547 The ``/`` token is used as a separator between pattern items as shown
3550 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
3552 Note that protocol items like these must be stacked from lowest to highest
3553 layer to make sense. For instance, the following rule is either invalid or
3554 unlikely to match any packet::
3556 testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
3558 More information on these restrictions can be found in the *rte_flow*
3561 Several items support additional specification structures, for example
3562 ``ipv4`` allows specifying source and destination addresses as follows::
3564 testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
3565 dst is 10.2.0.0 / end [...]
3567 This rule matches all IPv4 traffic with the specified properties.
3569 In this example, ``src`` and ``dst`` are field names of the underlying
3570 ``struct rte_flow_item_ipv4`` object. All item properties can be specified
3571 in a similar fashion.
3573 The ``is`` token means that the subsequent value must be matched exactly,
3574 and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
3575 accordingly. Possible assignment tokens are:
3577 - ``is``: match value perfectly (with full bit-mask).
3578 - ``spec``: match value according to configured bit-mask.
3579 - ``last``: specify upper bound to establish a range.
3580 - ``mask``: specify bit-mask with relevant bits set to one.
3581 - ``prefix``: generate bit-mask with <prefix-length> most-significant bits set to one.
3583 These yield identical results::
3585 ipv4 src is 10.1.1.1
3589 ipv4 src spec 10.1.1.1 src mask 255.255.255.255
3593 ipv4 src spec 10.1.1.1 src prefix 32
3597 ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
3601 ipv4 src is 10.1.1.1 src last 0 # 0 disables range
3603 Inclusive ranges can be defined with ``last``::
3605 ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
3607 Note that ``mask`` affects both ``spec`` and ``last``::
3609 ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0
3610 # matches 10.1.0.0 to 10.2.255.255
3612 Properties can be modified multiple times::
3614 ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
3618 ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16

3856 - ``tunnel_id {unsigned}``: L2TPv2 tunnel identifier.
3857 - ``session_id {unsigned}``: L2TPv2 session identifier.
3858 - ``ns {unsigned}``: L2TPv2 option ns.
3859 - ``nr {unsigned}``: L2TPv2 option nr.
3861 - ``ppp``: match PPP header.
3863 - ``addr {unsigned}``: PPP address.
3864 - ``ctrl {unsigned}``: PPP control.
3865 - ``proto_id {unsigned}``: PPP protocol identifier.
3870 A list of actions starts after the ``actions`` token in the same fashion as
3871 `Matching pattern`_; actions are separated by ``/`` tokens and the list is
3872 terminated by a mandatory ``end`` action.
3874 Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
3875 rte_flow_action_type``).
3877 Dropping all incoming UDPv4 packets can be expressed as follows::
3879 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3882 Several actions have configurable properties which must be specified when
3883 there is no valid default value. For example, ``queue`` requires a target
3886 This rule redirects incoming UDPv4 traffic to queue index 6::
3888 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3889 actions queue index 6 / end
3891 While this one could be rejected by PMDs (unspecified queue index)::
3893 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3896 As defined by *rte_flow*, the list is not ordered, all actions of a given
3897 rule are performed simultaneously. These are equivalent::
3899 queue index 6 / void / mark id 42 / end
3903 void / mark id 42 / queue index 6 / end
3905 All actions in a list should have different types, otherwise only the last
3906 action of a given type is taken into account::
3908 queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
3912 drop / drop / drop / end # drop is performed only once
3916 mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
3918 Considering they are performed simultaneously, opposite and overlapping
3919 actions can sometimes be combined when the end result is unambiguous::
3921 drop / queue index 6 / end # drop has no effect
3925 queue index 6 / rss queues 6 7 8 / end # queue has no effect
3929 drop / passthru / end # drop has no effect
3931 Note that PMDs may still refuse such combinations.

4152 Destroying flow rules
4153 ~~~~~~~~~~~~~~~~~~~~~
4155 ``flow destroy`` destroys one or more rules from their rule ID (as returned
4156 by ``flow create``), this command calls ``rte_flow_destroy()`` as many
4157 times as necessary::
4159 flow destroy {port_id} rule {rule_id} [...]
4161 If successful, it will show::
4163 Flow rule #[...] destroyed
4165 It does not report anything for rule IDs that do not exist. The usual error
4166 message is shown when a rule cannot be destroyed::
4168 Caught error type [...] ([...]): [...]
4170 ``flow flush`` destroys all rules on a device and does not take extra
4171 arguments. It is bound to ``rte_flow_flush()``::
4173 flow flush {port_id}
4175 Any errors are reported as above.
4177 Creating several rules and destroying them::
4179 testpmd> flow create 0 ingress pattern eth / ipv6 / end
4180 actions queue index 2 / end
4181 Flow rule #0 created
4182 testpmd> flow create 0 ingress pattern eth / ipv4 / end
4183 actions queue index 3 / end
4184 Flow rule #1 created
4185 testpmd> flow destroy 0 rule 0 rule 1
4186 Flow rule #1 destroyed
4187 Flow rule #0 destroyed
4190 The same result can be achieved using ``flow flush``::
4192 testpmd> flow create 0 ingress pattern eth / ipv6 / end
4193 actions queue index 2 / end
4194 Flow rule #0 created
4195 testpmd> flow create 0 ingress pattern eth / ipv4 / end
4196 actions queue index 3 / end
4197 Flow rule #1 created
4198 testpmd> flow flush 0
4201 Non-existent rule IDs are ignored::
4203 testpmd> flow create 0 ingress pattern eth / ipv6 / end
4204 actions queue index 2 / end
4205 Flow rule #0 created
4206 testpmd> flow create 0 ingress pattern eth / ipv4 / end
4207 actions queue index 3 / end
4208 Flow rule #1 created
4209 testpmd> flow destroy 0 rule 42 rule 10 rule 2
4211 testpmd> flow destroy 0 rule 0
4212 Flow rule #0 destroyed
4218 ``flow query`` queries a specific action of a flow rule having that
4219 ability. Such actions collect information that can be reported using this
4220 command. It is bound to ``rte_flow_query()``::
4222 flow query {port_id} {rule_id} {action}
4224 If successful, it will display either the retrieved data for known actions
4225 or the following message::
4227 Cannot display result for action type [...] ([...])
4229 Otherwise, it will complain either that the rule does not exist or that some
4232 Flow rule #[...] not found
4236 Caught error type [...] ([...]): [...]
4238 Currently only the ``count`` action is supported. This action reports the
4239 number of packets that hit the flow rule and the total number of bytes. Its
4240 output has the following format::
4243 hits_set: [...] # whether "hits" contains a valid value
4244 bytes_set: [...] # whether "bytes" contains a valid value
4245 hits: [...] # number of packets
4246 bytes: [...] # number of bytes
4248 Querying counters for TCPv6 packets redirected to queue 6::
4250 testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
4251 actions queue index 6 / count / end
4252 Flow rule #4 created
4253 testpmd> flow query 0 4 count
4264 ``flow list`` lists existing flow rules sorted by priority and optionally
4265 filtered by group identifiers::
4267 flow list {port_id} [group {group_id}] [...]
4269 This command only fails with the following message if the device does not
4274 Output consists of a header line followed by a short description of each
4275 flow rule, one per line. There is no output at all when no flow rules are
4276 configured on the device::
4278 ID Group Prio Attr Rule
4279 [...] [...] [...] [...] [...]
4281 ``Attr`` column flags:
4283 - ``i`` for ``ingress``.
4284 - ``e`` for ``egress``.
4286 Creating several flow rules and listing them::
4288 testpmd> flow create 0 ingress pattern eth / ipv4 / end
4289 actions queue index 6 / end
4290 Flow rule #0 created
4291 testpmd> flow create 0 ingress pattern eth / ipv6 / end
4292 actions queue index 2 / end
4293 Flow rule #1 created
4294 testpmd> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
4295 actions rss queues 6 7 8 end / end
4296 Flow rule #2 created
4297 testpmd> flow list 0
4298 ID Group Prio Attr Rule
4299 0 0 0 i- ETH IPV4 => QUEUE
4300 1 0 0 i- ETH IPV6 => QUEUE
4301 2 0 5 i- ETH IPV4 UDP => RSS
4304 Rules are sorted by priority (i.e. group ID first, then priority level)::
4306 testpmd> flow list 1
4307 ID Group Prio Attr Rule
4308 0 0 0 i- ETH => COUNT
4309 6 0 500 i- ETH IPV6 TCP => DROP COUNT
4310 5 0 1000 i- ETH IPV6 ICMP => QUEUE
4311 1 24 0 i- ETH IPV4 UDP => QUEUE
4312 4 24 10 i- ETH IPV4 TCP => DROP
4313 3 24 20 i- ETH IPV4 => DROP
4314 2 24 42 i- ETH IPV4 UDP => QUEUE
4315 7 63 0 i- ETH IPV6 UDP VXLAN => MARK QUEUE
4318 Output can be limited to specific groups::
4320 testpmd> flow list 1 group 0 group 63
4321 ID Group Prio Attr Rule
4322 0 0 0 i- ETH => COUNT
4323 6 0 500 i- ETH IPV6 TCP => DROP COUNT
4324 5 0 1000 i- ETH IPV6 ICMP => QUEUE
4325 7 63 0 i- ETH IPV6 UDP VXLAN => MARK QUEUE
4328 Toggling isolated mode
4329 ~~~~~~~~~~~~~~~~~~~~~~
4331 ``flow isolate`` can be used to tell the underlying PMD that ingress traffic
4332 must only be injected from the defined flow rules; that no default traffic
4333 is expected outside those rules and the driver is free to assign more
4334 resources to handle them. It is bound to ``rte_flow_isolate()``::
4336 flow isolate {port_id} {boolean}
4338 If successful, enabling or disabling isolated mode shows either::
4340 Ingress traffic on port [...]
4341 is now restricted to the defined flow rules
4345 Ingress traffic on port [...]
4346 is not restricted anymore to the defined flow rules
4348 Otherwise, in case of error::
4350 Caught error type [...] ([...]): [...]
4352 Mainly due to its side effects, PMDs supporting this mode may not have the
4353 ability to toggle it more than once without reinitializing affected ports
4354 first (e.g. by exiting testpmd).
4356 Enabling isolated mode::
4358 testpmd> flow isolate 0 true
4359 Ingress traffic on port 0 is now restricted to the defined flow rules
4362 Disabling isolated mode::
4364 testpmd> flow isolate 0 false
4365 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
4368 Dumping HW internal information
4369 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4371 ``flow dump`` dumps the hardware's internal representation information of
4372 all flows. It is bound to ``rte_flow_dev_dump()``::
4374 flow dump {port_id} {output_file}
4376 If successful, it will show::
4380 Otherwise, it will complain error occurred::
4382 Caught error type [...] ([...]): [...]
4384 Listing and destroying aged flow rules
4385 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4387 ``flow aged`` simply lists aged flow rules be get from api ``rte_flow_get_aged_flows``,
4388 and ``destroy`` parameter can be used to destroy those flow rules in PMD.
4390 flow aged {port_id} [destroy]
4392 Listing current aged flow rules::
4394 testpmd> flow aged 0
4395 Port 0 total aged flows: 0
4396 testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.14 / end
4397 actions age timeout 5 / queue index 0 / end
4398 Flow rule #0 created
4399 testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.15 / end
4400 actions age timeout 4 / queue index 0 / end
4401 Flow rule #1 created
4402 testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.16 / end
4403 actions age timeout 2 / queue index 0 / end
4404 Flow rule #2 created
4405 testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.17 / end
4406 actions age timeout 3 / queue index 0 / end
4407 Flow rule #3 created
4410 Aged Rules are simply list as command ``flow list {port_id}``, but strip the detail rule
4411 information, all the aged flows are sorted by the longest timeout time. For example, if
4412 those rules be configured in the same time, ID 2 will be the first aged out rule, the next
4413 will be ID 3, ID 1, ID 0::
4415 testpmd> flow aged 0
4416 Port 0 total aged flows: 4
4423 If attach ``destroy`` parameter, the command will destroy all the list aged flow rules.
4425 testpmd> flow aged 0 destroy
4426 Port 0 total aged flows: 4
4433 Flow rule #2 destroyed
4434 Flow rule #3 destroyed
4435 Flow rule #1 destroyed
4436 Flow rule #0 destroyed
4437 4 flows be destroyed
4438 testpmd> flow aged 0
4439 Port 0 total aged flows: 0
4441 Creating indirect actions
4442 ~~~~~~~~~~~~~~~~~~~~~~~~~
4444 ``flow indirect_action {port_id} create`` creates indirect action with optional
4445 indirect action ID. It is bound to ``rte_flow_action_handle_create()``::
4447 flow indirect_action {port_id} create [action_id {indirect_action_id}]
4448 [ingress] [egress] [transfer] action {action} / end
4450 If successful, it will show::
4452 Indirect action #[...] created
4454 Otherwise, it will complain either that indirect action already exists or that
4455 some error occurred::
4457 Indirect action #[...] is already assigned, delete it first
4461 Caught error type [...] ([...]): [...]
4463 Create indirect rss action with id 100 to queues 1 and 2 on port 0::
4465 testpmd> flow indirect_action 0 create action_id 100 \
4466 ingress action rss queues 1 2 end / end
4468 Create indirect rss action with id assigned by testpmd to queues 1 and 2 on
4471 testpmd> flow indirect_action 0 create action_id \
4472 ingress action rss queues 0 1 end / end
4474 Updating indirect actions
4475 ~~~~~~~~~~~~~~~~~~~~~~~~~
4477 ``flow indirect_action {port_id} update`` updates configuration of the indirect
4478 action from its indirect action ID (as returned by
4479 ``flow indirect_action {port_id} create``). It is bound to
4480 ``rte_flow_action_handle_update()``::
4482 flow indirect_action {port_id} update {indirect_action_id}
4483 action {action} / end
4485 If successful, it will show::
4487 Indirect action #[...] updated
4489 Otherwise, it will complain either that indirect action not found or that some
4492 Failed to find indirect action #[...] on port [...]
4496 Caught error type [...] ([...]): [...]
4498 Update indirect rss action having id 100 on port 0 with rss to queues 0 and 3
4499 (in create example above rss queues were 1 and 2)::
4501 testpmd> flow indirect_action 0 update 100 action rss queues 0 3 end / end
4503 Destroying indirect actions
4504 ~~~~~~~~~~~~~~~~~~~~~~~~~~~
4506 ``flow indirect_action {port_id} destroy`` destroys one or more indirect actions
4507 from their indirect action IDs (as returned by
4508 ``flow indirect_action {port_id} create``). It is bound to
4509 ``rte_flow_action_handle_destroy()``::
4511 flow indirect_action {port_id} destroy action_id {indirect_action_id} [...]
4513 If successful, it will show::
4515 Indirect action #[...] destroyed
4517 It does not report anything for indirect action IDs that do not exist.
4518 The usual error message is shown when a indirect action cannot be destroyed::
4520 Caught error type [...] ([...]): [...]
4522 Destroy indirect actions having id 100 & 101::
4524 testpmd> flow indirect_action 0 destroy action_id 100 action_id 101
4526 Query indirect actions
4527 ~~~~~~~~~~~~~~~~~~~~~~
4529 ``flow indirect_action {port_id} query`` queries the indirect action from its
4530 indirect action ID (as returned by ``flow indirect_action {port_id} create``).
4531 It is bound to ``rte_flow_action_handle_query()``::
4533 flow indirect_action {port_id} query {indirect_action_id}
4535 Currently only rss indirect action supported. If successful, it will show::
4537 Indirect RSS action:
4540 Otherwise, it will complain either that indirect action not found or that some
4543 Failed to find indirect action #[...] on port [...]
4547 Caught error type [...] ([...]): [...]
4549 Query indirect action having id 100::
4551 testpmd> flow indirect_action 0 query 100
4553 Sample QinQ flow rules
4554 ~~~~~~~~~~~~~~~~~~~~~~
4556 Before creating QinQ rule(s) the following commands should be issued to enable QinQ::
4558 testpmd> port stop 0
4559 testpmd> vlan set extend on 0
4561 The above command sets the inner and outer TPID's to 0x8100.
4563 To change the TPID's the following commands should be used::
4565 testpmd> vlan set outer tpid 0x88A8 0
4566 testpmd> vlan set inner tpid 0x8100 0
4567 testpmd> port start 0
4569 Validate and create a QinQ rule on port 0 to steer traffic to a VF queue in a VM.
4573 testpmd> flow validate 0 ingress pattern eth / vlan tci is 123 /
4574 vlan tci is 456 / end actions vf id 1 / queue index 0 / end
4575 Flow rule #0 validated
4577 testpmd> flow create 0 ingress pattern eth / vlan tci is 4 /
4578 vlan tci is 456 / end actions vf id 123 / queue index 0 / end
4579 Flow rule #0 created

5096 PPPoL2TPv2oUDP RSS rules can be created by the following commands::
5098 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / l2tpv2 / ppp / ipv4
5099 / end actions rss types ipv4 end queues end / end
5100 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / l2tpv2 / ppp / ipv6
5101 / udp / end actions rss types ipv6-udp end queues end / end
5102 testpmd> flow create 0 ingress pattern eth / ipv6 / udp / l2tpv2 / ppp / ipv4
5103 / tcp / end actions rss types ipv4-tcp end queues end / end
5104 testpmd> flow create 0 ingress pattern eth / ipv6 / udp / l2tpv2 / ppp / ipv6
5105 / end actions rss types ipv6 end queues end / end
5110 A RAW rule can be created as following using ``pattern_hex`` key and mask.
5114 testpmd> flow create 0 group 0 priority 1 ingress pattern raw relative is 0 search is 0 offset
5115 is 0 limit is 0 pattern_hex spec 00000000000000000000000000000000000000000000000000000a0a0a0a
5116 pattern_hex mask 0000000000000000000000000000000000000000000000000000ffffffff / end actions
5122 The following sections show functions to load/unload eBPF based filters.
5127 Load an eBPF program as a callback for particular RX/TX queue::
5129 testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)
5131 The available load-flags are:
5133 * ``J``: use JIT generated native code, otherwise BPF interpreter will be used.
5135 * ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.
5141 You'll need clang v3.7 or above to build bpf program you'd like to load
5145 .. code-block:: console
5148 clang -O2 -target bpf -c t1.c
5150 Then to load (and JIT compile) t1.o at RX queue 0, port 1:
5152 .. code-block:: console
5154 testpmd> bpf-load rx 1 0 J ./dpdk.org/examples/bpf/t1.o
5156 To load (not JITed) t1.o at TX queue 0, port 0:
5158 .. code-block:: console
5160 testpmd> bpf-load tx 0 0 - ./dpdk.org/examples/bpf/t1.o
5165 Unload previously loaded eBPF program for particular RX/TX queue::
5167 testpmd> bpf-unload rx|tx (portid) (queueid)
5169 For example to unload BPF filter from TX queue 0, port 0:
5171 .. code-block:: console
5173 testpmd> bpf-unload tx 0 0
5178 The following sections show functions that configure and create flex item object,
5179 create flex pattern and use it in a flow rule.
5180 The commands will use 20 bytes IPv4 header for examples:
5185 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
5186 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
5187 | ver | IHL | TOS | length | +0
5188 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
5189 | identification | flg | frag. offset | +4
5190 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

5196 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
5202 Flex item object is created by PMD according to a new header configuration. The
5203 header configuration is compiled by the testpmd and stored in
5204 ``rte_flow_item_flex_conf`` type variable.
5208 # flow flex_item create <port> <flex id> <configuration file>
5209 testpmd> flow flex_item init 0 3 ipv4_flex_config.json
5210 port-0: created flex item #3
5212 Flex item configuration is kept in external JSON file.
5213 It describes the following header elements:
5215 **New header length.**
5217 Specify whether the new header has fixed or variable length and the basic/minimal
5218 header length value.
5220 If header length is not fixed, header location with a value that completes header
5221 length calculation and scale/offset function must be added.
5223 Scale function depends on port hardware.
5227 Describes location in the new header that specify following network header type.
5229 **Flow match samples.**
5231 Describes locations in the new header that will be used in flow rules.
5233 Number of flow samples and sample maximal length depend of port hardware.
5237 Describes preceding network header configuration.
5241 Describes conditions that trigger transfer to following network header
5243 .. code-block:: json
5246 "next_header": { "field_mode": "FIELD_MODE_FIXED", "field_size": 20},
5247 "next_protocol": {"field_size": 8, "field_base": 72},

5250 { "field_mode": "FIELD_MODE_FIXED", "field_size": 32, "field_base": 32},
5251 { "field_mode": "FIELD_MODE_FIXED", "field_size": 32, "field_base": 64},
5252 { "field_mode": "FIELD_MODE_FIXED", "field_size": 32, "field_base": 96}
5255 {"item": "eth type is 0x0800"},
5256 {"item": "vlan inner_type is 0x0800"}
5259 {"item": "udp", "next": 17},
5260 {"item": "tcp", "next": 6},
5261 {"item": "icmp", "next": 1}
5266 Flex pattern and flow rules
5267 ~~~~~~~~~~~~~~~~~~~~~~~~~~~
5269 Flex pattern describe parts of network header that will trigger flex flow item hit in a flow rule.
5270 Flex pattern directly related to flex item samples configuration.
5271 Flex pattern can be shared between ports.
5273 **Flex pattern and flow rule to match IPv4 version and 20 bytes length**
5277 # set flex_pattern <pattern_id> is <hex bytes sequence>
5278 testpmd> flow flex_item pattern 5 is 45FF
5281 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / flex item is 3 pattern is 5 / end actions mark id 1 / queue index 0 / end
5282 Flow rule #0 created
5284 **Flex pattern and flow rule to match packets with source address 1.2.3.4**
5288 testpmd> flow flex_item pattern 2 spec 45000000000000000000000001020304 mask FF0000000000000000000000FFFFFFFF
5291 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / flex item is 3 pattern is 2 / end actions mark id 1 / queue index 0 / end
5292 Flow rule #0 created
