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|stat_qmap|dcb_tc|cap X
28 info [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|stat_qmap|dcb_tc|cap all
29 stats [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|stat_qmap|dcb_tc|cap X
30 stats [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|stat_qmap|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
76 CLI commands to be read from /home/ubuntu/flow-create-commands.txt

89 Flow rule #498 created
90 Flow rule #499 created
91 Read all CLI commands from /home/ubuntu/flow-create-commands.txt
95 * At run-time additional commands can be loaded in bulk by invoking the ``load FILENAME``
98 .. code-block:: console
100 testpmd> load /home/ubuntu/flow-create-commands.txt
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|stat_qmap|dcb_tc|cap) (port_id|all)
164 The available information categories are:
166 * ``info``: General port information such as MAC address.

305 TX threshold registers: pthresh=36 hthresh=0 wthresh=0
306 TX RS bit threshold=0 - TXQ flags=0x0
311 Set the packet forwarding mode::
313 testpmd> set fwd (io|mac|macswap|flowgen| \
314 rxonly|txonly|csum|icmpecho|noisy|5tswap) (""|retry)
316 ``retry`` can be specified for forwarding engines except ``rx_only``.
318 The available information categories are:
320 * ``io``: Forwards packets "as-is" in I/O mode.
321 This is the fastest possible forwarding operation as it does not access packets data.
322 This is the default mode.
324 * ``mac``: Changes the source and the destination Ethernet addresses of packets before forwarding them.
325 Default application behavior is to set source Ethernet address to that of the transmitting interface, and destination
326 address to a dummy value (set during init). The user may specify a target destination Ethernet address via the 'eth-peer' or
327 'eth-peers-configfile' command-line options. It is not currently possible to specify a specific source Ethernet address.
329 * ``macswap``: MAC swap forwarding mode.
330 Swaps the source and the destination Ethernet addresses of packets before forwarding them.
332 * ``flowgen``: Multi-flow generation mode.
333 Originates a number of flows (with varying destination IP addresses), and terminate receive traffic.
335 * ``rxonly``: Receives packets but doesn't transmit them.
337 * ``txonly``: Generates and transmits packets without receiving any.
339 * ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet.
341 * ``icmpecho``: Receives a burst of packets, lookup for ICMP echo requests and, if any, send back ICMP echo replies.
343 * ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX.
345 * ``noisy``: Noisy neighbor simulation.
346 Simulate more realistic behavior of a guest machine engaged in receiving
347 and sending packets performing Virtual Network Function (VNF).
349 * ``5tswap``: Swap the source and destination of L2,L3,L4 if they exist.
351 L2 swaps the source address and destination address of Ethernet, as same as ``macswap``.
353 L3 swaps the source address and destination address of IP (v4 and v6).
355 L4 swaps the source port and destination port of transport layer (TCP and UDP).
359 testpmd> set fwd rxonly
361 Set rxonly packet forwarding mode
367 When running, forwarding engines maintain statistics from the time they have been started.
368 Example for the io forwarding engine, with some packet drops on the tx side::

636 Configuration Functions
637 -----------------------
639 The testpmd application can be configured from the runtime as well as from the command-line.
641 This section details the available configuration functions that are available.
645 Configuration changes only become active when forwarding is started/restarted.
650 Reset forwarding to the default configuration::
657 Set the debug verbosity level::
659 testpmd> set verbose (level)
661 Available levels are as following:
663 * ``0`` silent except for error.
664 * ``1`` fully verbose except for Tx packets.
665 * ``2`` fully verbose except for Rx packets.
666 * ``> 2`` fully verbose.
671 Set the log level for a log type::
673 testpmd> set log global|(type) (level)
677 * ``type`` is the log name.
679 * ``level`` is the log level.
681 For example, to change the global log level::
683 testpmd> set log global (level)
685 Regexes can also be used for type. To change log level of user1, user2 and user3::
687 testpmd> set log user[1-3] (level)
692 Set the number of ports used by the application:
696 This is equivalent to the ``--nb-ports`` command-line option.
701 Set the number of cores used by the application::
703 testpmd> set nbcore (num)
705 This is equivalent to the ``--nb-cores`` command-line option.
709 The number of cores used must not be greater than number of ports used multiplied by the number of queues per port.
714 Set the forwarding cores hexadecimal mask::
716 testpmd> set coremask (mask)
718 This is equivalent to the ``--coremask`` command-line option.
722 The main lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
727 Set the forwarding ports hexadecimal mask::
729 testpmd> set portmask (mask)
731 This is equivalent to the ``--portmask`` command-line option.
733 set record-core-cycles
734 ~~~~~~~~~~~~~~~~~~~~~~
736 Set the recording of CPU cycles::
738 testpmd> set record-core-cycles (on|off)
742 * ``on`` enables measurement of CPU cycles per packet.
744 * ``off`` disables measurement of CPU cycles per packet.
746 This is equivalent to the ``--record-core-cycles command-line`` option.
748 set record-burst-stats
749 ~~~~~~~~~~~~~~~~~~~~~~
751 Set the displaying of RX and TX bursts::
753 testpmd> set record-burst-stats (on|off)
757 * ``on`` enables display of RX and TX bursts.
759 * ``off`` disables display of RX and TX bursts.
761 This is equivalent to the ``--record-burst-stats command-line`` option.
766 Set number of packets per burst::
768 testpmd> set burst (num)
770 This is equivalent to the ``--burst command-line`` option.
772 When retry is enabled, the transmit delay time and number of retries can also be set::
774 testpmd> set burst tx delay (microseconds) retry (num)
779 Set the offsets of segments relating to the data buffer beginning on receiving
780 if split feature is engaged. Affects only the queues configured with split
781 offloads (currently BUFFER_SPLIT is supported only).
783 testpmd> set rxoffs (x[,y]*)
785 Where x[,y]* represents a CSV list of values, without white space. If the list
786 of offsets is shorter than the list of segments the zero offsets will be used
787 for the remaining segments.
792 Set the length of segments to scatter packets on receiving if split
793 feature is engaged. Affects only the queues configured with split offloads
794 (currently BUFFER_SPLIT is supported only). Optionally the multiple memory
795 pools can be specified with --mbuf-size command line parameter and the mbufs
796 to receive will be allocated sequentially from these extra memory pools (the
797 mbuf for the first segment is allocated from the first pool, the second one
798 from the second pool, and so on, if segment number is greater then pool's the
799 mbuf for remaining segments will be allocated from the last valid pool).
801 testpmd> set rxpkts (x[,y]*)
803 Where x[,y]* represents a CSV list of values, without white space. Zero value
804 means to use the corresponding memory pool data buffer size.
809 Set the length of each segment of the TX-ONLY packets or length of packet for FLOWGEN mode::
811 testpmd> set txpkts (x[,y]*)
813 Where x[,y]* represents a CSV list of values, without white space.
818 Configure the timing burst pattern for Tx only mode. This command enables
819 the packet send scheduling on dynamic timestamp mbuf field and configures
820 timing pattern in Tx only mode. In this mode, if scheduling is enabled
821 application provides timestamps in the packets being sent. It is possible
822 to configure delay (in unspecified device clock units) between bursts
823 and between the packets within the burst::
825 testpmd> set txtimes (inter),(intra)
829 * ``inter`` is the delay between the bursts in the device clock units.
830 If ``intra`` is zero, this is the time between the beginnings of the
831 first packets in the neighbour bursts, if ``intra`` is not zero,
832 ``inter`` specifies the time between the beginning of the first packet
833 of the current burst and the beginning of the last packet of the
834 previous burst. If ``inter`` parameter is zero the send scheduling
835 on timestamps is disabled (default).
837 * ``intra`` is the delay between the packets within the burst specified
838 in the device clock units. The number of packets in the burst is defined
839 by regular burst setting. If ``intra`` parameter is zero no timestamps
840 provided in the packets excepting the first one in the burst.
842 As the result the bursts of packet will be transmitted with specific
843 delays between the packets within the burst and specific delay between
844 the bursts. The rte_eth_read_clock() must be supported by the device(s)
845 and is supposed to be engaged to get the current device clock value
846 and provide the reference for the timestamps. If there is no supported
847 rte_eth_read_clock() there will be no send scheduling provided on the port.
852 Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes::
854 testpmd> set txsplit (off|on|rand)
858 * ``off`` disable packet copy & split for CSUM mode.
860 * ``on`` split outgoing packet into multiple segments. Size of each segment
861 and number of segments per packet is determined by ``set txpkts`` command
864 * ``rand`` same as 'on', but number of segments per each packet is a random value between 1 and total number of segments.
869 Set the list of forwarding cores::
871 testpmd> set corelist (x[,y]*)
873 For example, to change the forwarding cores:
875 .. code-block:: console
877 testpmd> set corelist 3,1
878 testpmd> show config fwd
880 io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled
881 Logical Core 3 (socket 0) forwards packets on 1 streams:
882 RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
883 Logical Core 1 (socket 0) forwards packets on 1 streams:
884 RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
888 The cores are used in the same order as specified on the command line.
893 Set the list of forwarding ports::
895 testpmd> set portlist (x[,y]*)
897 For example, to change the port forwarding:
899 .. code-block:: console
901 testpmd> set portlist 0,2,1,3
902 testpmd> show config fwd
904 io packet forwarding - ports=4 - cores=1 - streams=4
905 Logical Core 3 (socket 0) forwards packets on 4 streams:
906 RX P=0/Q=0 (socket 0) -> TX P=2/Q=0 (socket 0) peer=02:00:00:00:00:01
907 RX P=2/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
908 RX P=1/Q=0 (socket 0) -> TX P=3/Q=0 (socket 0) peer=02:00:00:00:00:03
909 RX P=3/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:02
914 Select how to retrieve new ports created after "port attach" command::
916 testpmd> set port setup on (iterator|event)
918 For each new port, a setup is done.

1044 Add a VLAN ID, or all identifiers, to the set of VLAN identifiers filtered by port ID::
1046 testpmd> rx_vlan add (vlan_id|all) (port_id)
1050 VLAN filter must be set on that port. VLAN ID < 4096.
1051 Depending on the NIC used, number of vlan_ids may be limited to the maximum entries

1123 transmitting a packet using the ``csum`` forwarding engine::
1125 testpmd> csum set (ip|udp|tcp|sctp|outer-ip|outer-udp) (hw|sw) (port_id)
1129 * ``ip|udp|tcp|sctp`` always relate to the inner layer.
1131 * ``outer-ip`` relates to the outer IP layer (only for IPv4) in the case where the packet is recognized
1132 as a tunnel packet by the forwarding engine (geneve, gre, gtp, ipip, vxlan and vxlan-gpe are
1133 supported). See also the ``csum parse-tunnel`` command.
1135 * ``outer-udp`` relates to the outer UDP layer in the case where the packet is recognized
1136 as a tunnel packet by the forwarding engine (geneve, gtp, vxlan and vxlan-gpe are
1137 supported). See also the ``csum parse-tunnel`` command.
1141 Check the NIC Datasheet for hardware limits.

1166 testpmd> set port (port_id) queue-region flush (on|off)
1170 * ``on``: is just an enable function which server for other configuration,
1171 it is for all configuration about queue region from up layer,
1172 at first will only keep in DPDK software stored in driver,
1173 only after "flush on", it commit all configuration to HW.
1175 * ``"off``: is just clean all configuration about queue region just now,
1176 and restore all to DPDK i40e driver default config when start up.
1178 Show all queue region related configuration info on a port::
1180 testpmd> show port (port_id) queue-region
1184 Queue region only support on PF by now, so these command is
1185 only for configuration of queue region on PF port.
1190 Define how tunneled packets should be handled by the csum forward
1193 testpmd> csum parse-tunnel (on|off) (tx_port_id)
1195 If enabled, the csum forward engine will try to recognize supported
1196 tunnel headers (geneve, gtp, gre, ipip, vxlan, vxlan-gpe).
1198 If disabled, treat tunnel packets as non-tunneled packets (a inner
1199 header is handled as a packet payload).
1203 The port argument is the TX port like in the ``csum set`` command.
1207 Consider a packet in packet like the following::
1209 eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in
1211 * If parse-tunnel is enabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
1212 command relate to the inner headers (here ``ipv4_in`` and ``tcp_in``), and the
1213 ``outer-ip|outer-udp`` parameter relates to the outer headers (here ``ipv4_out`` and ``udp_out``).
1215 * If parse-tunnel is disabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
1216 command relate to the outer headers, here ``ipv4_out`` and ``udp_out``.

1248 testpmd> tunnel_tso set (tso_segsz) (port_id)
1253 Display the status of tunneled TCP Segmentation Offload for a port::
1255 testpmd> tunnel_tso show (port_id)
1260 Enable or disable GRO in ``csum`` forwarding engine::
1262 testpmd> set port <port_id> gro on|off
1264 If enabled, the csum forwarding engine will perform GRO on the TCP/IPv4
1265 packets received from the given port.
1267 If disabled, packets received from the given port won't be performed
1268 GRO. By default, GRO is disabled for all ports.
1272 When enable GRO for a port, TCP/IPv4 packets received from the port
1273 will be performed GRO. After GRO, all merged packets have bad
1274 checksums, since the GRO library doesn't re-calculate checksums for
1275 the merged packets. Therefore, if users want the merged packets to
1276 have correct checksums, please select HW IP checksum calculation and
1277 HW TCP checksum calculation for the port which the merged packets are
1283 Display GRO configuration for a given port::
1285 testpmd> show port <port_id> gro
1290 Set the cycle to flush the GROed packets from reassembly tables::
1292 testpmd> set gro flush <cycles>
1294 When enable GRO, the csum forwarding engine performs GRO on received
1295 packets, and the GROed packets are stored in reassembly tables. Users
1296 can use this command to determine when the GROed packets are flushed
1297 from the reassembly tables.
1299 The ``cycles`` is measured in GRO operation times. The csum forwarding
1300 engine flushes the GROed packets from the tables every ``cycles`` GRO
1303 By default, the value of ``cycles`` is 1, which means flush GROed packets
1304 from the reassembly tables as soon as one GRO operation finishes. The value
1305 of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``.
1307 Please note that the large value of ``cycles`` may cause the poor TCP/IP
1308 stack performance. Because the GROed packets are delayed to arrive the
1309 stack, thus causing more duplicated ACKs and TCP retransmissions.
1314 Toggle per-port GSO support in ``csum`` forwarding engine::
1316 testpmd> set port <port_id> gso on|off
1318 If enabled, the csum forwarding engine will perform GSO on supported IPv4
1319 packets, transmitted on the given port.
1321 If disabled, packets transmitted on the given port will not undergo GSO.
1322 By default, GSO is disabled for all ports.
1326 When GSO is enabled on a port, supported IPv4 packets transmitted on that
1327 port undergo GSO. Afterwards, the segmented packets are represented by
1328 multi-segment mbufs; however, the csum forwarding engine doesn't calculation
1329 of checksums for GSO'd segments in SW. As a result, if users want correct
1330 checksums in GSO segments, they should enable HW checksum calculation for
1333 For example, HW checksum calculation for VxLAN GSO'd packets may be enabled
1334 by setting the following options in the csum forwarding engine:
1336 testpmd> csum set outer_ip hw <port_id>
1338 testpmd> csum set ip hw <port_id>
1340 testpmd> csum set tcp hw <port_id>
1342 UDP GSO is the same as IP fragmentation, which treats the UDP header
1343 as the payload and does not modify it during segmentation. That is,
1344 after UDP GSO, only the first output fragment has the original UDP
1345 header. Therefore, users need to enable HW IP checksum calculation
1346 and SW UDP checksum calculation for GSO-enabled ports, if they want
1347 correct checksums for UDP/IPv4 packets.
1352 Set the maximum GSO segment size (measured in bytes), which includes the
1353 packet header and the packet payload for GSO-enabled ports (global)::
1355 testpmd> set gso segsz <length>

1997 Set fec mode for a specific port::
1999 testpmd> set port (port_id) fec_mode auto|off|rs|baser
2005 The following sections show functions for configuring ports.
2009 Port configuration changes only become active when forwarding is started/restarted.
2014 Attach a port specified by pci address or virtual device args::
2016 testpmd> port attach (identifier)
2018 To attach a new pci device, the device should be recognized by kernel first.
2019 Then it should be moved under DPDK management.
2020 Finally the port can be attached to testpmd.
2022 For example, to move a pci device using ixgbe under DPDK management:
2024 .. code-block:: console
2026 # Check the status of the available devices.
2027 ./usertools/dpdk-devbind.py --status
2029 Network devices using DPDK-compatible driver
2030 ============================================
2033 Network devices using kernel driver
2034 ===================================
2035 0000:0a:00.0 '82599ES 10-Gigabit' if=eth2 drv=ixgbe unused=
2038 # Bind the device to igb_uio.
2039 sudo ./usertools/dpdk-devbind.py -b igb_uio 0000:0a:00.0
2042 # Recheck the status of the devices.
2043 ./usertools/dpdk-devbind.py --status
2044 Network devices using DPDK-compatible driver
2045 ============================================
2046 0000:0a:00.0 '82599ES 10-Gigabit' drv=igb_uio unused=
2048 To attach a port created by virtual device, above steps are not needed.
2050 For example, to attach a port whose pci address is 0000:0a:00.0.
2052 .. code-block:: console
2054 testpmd> port attach 0000:0a:00.0
2055 Attaching a new port...
2056 EAL: PCI device 0000:0a:00.0 on NUMA socket -1
2057 EAL: probe driver: 8086:10fb rte_ixgbe_pmd
2058 EAL: PCI memory mapped at 0x7f83bfa00000
2059 EAL: PCI memory mapped at 0x7f83bfa80000
2060 PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
2061 PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
2062 Port 0 is attached. Now total ports is 1
2065 For example, to attach a port created by pcap PMD.
2067 .. code-block:: console
2069 testpmd> port attach net_pcap0
2070 Attaching a new port...
2071 PMD: Initializing pmd_pcap for net_pcap0
2072 PMD: Creating pcap-backed ethdev on numa socket 0
2073 Port 0 is attached. Now total ports is 1
2076 In this case, identifier is ``net_pcap0``.
2077 This identifier format is the same as ``--vdev`` format of DPDK applications.
2079 For example, to re-attach a bonded port which has been previously detached,
2080 the mode and slave parameters must be given.
2082 .. code-block:: console
2084 testpmd> port attach net_bond_0,mode=0,slave=1
2085 Attaching a new port...
2086 EAL: Initializing pmd_bond for net_bond_0
2087 EAL: Create bonded device net_bond_0 on port 0 in mode 0 on socket 0.
2088 Port 0 is attached. Now total ports is 1
2095 Detach a specific port::
2097 testpmd> port detach (port_id)
2099 Before detaching a port, the port should be stopped and closed.
2101 For example, to detach a pci device port 0.
2103 .. code-block:: console
2105 testpmd> port stop 0
2108 testpmd> port close 0
2112 testpmd> port detach 0
2114 EAL: PCI device 0000:0a:00.0 on NUMA socket -1
2115 EAL: remove driver: 8086:10fb rte_ixgbe_pmd
2116 EAL: PCI memory unmapped at 0x7f83bfa00000
2117 EAL: PCI memory unmapped at 0x7f83bfa80000
2121 For example, to detach a virtual device port 0.
2123 .. code-block:: console
2125 testpmd> port stop 0
2128 testpmd> port close 0
2132 testpmd> port detach 0
2134 PMD: Closing pcap ethdev on numa socket 0
2135 Port 'net_pcap0' is detached. Now total ports is 0
2138 To remove a pci device completely from the system, first detach the port from testpmd.
2139 Then the device should be moved under kernel management.
2140 Finally the device can be removed using kernel pci hotplug functionality.
2142 For example, to move a pci device under kernel management:
2144 .. code-block:: console
2146 sudo ./usertools/dpdk-devbind.py -b ixgbe 0000:0a:00.0
2148 ./usertools/dpdk-devbind.py --status
2150 Network devices using DPDK-compatible driver

2155 ===================================
2156 0000:0a:00.0 '82599ES 10-Gigabit' if=eth2 drv=ixgbe unused=igb_uio
2158 To remove a port created by a virtual device, above steps are not needed.
2163 Start all ports or a specific port::
2165 testpmd> port start (port_id|all)
2170 Stop all ports or a specific port::
2172 testpmd> port stop (port_id|all)

2275 RSS is on by default.
2277 The ``all`` option is equivalent to eth|vlan|ip|tcp|udp|sctp|ether|l2tpv3|esp|ah|pfcp.
2279 The ``default`` option enables all supported RSS types reported by device info.
2281 The ``none`` option is equivalent to the ``--disable-rss`` command-line option.

2470 Link Bonding Functions
2471 ----------------------
2473 The Link Bonding functions make it possible to dynamically create and
2474 manage link bonding devices from within testpmd interactive prompt.
2476 create bonded device
2477 ~~~~~~~~~~~~~~~~~~~~
2479 Create a new bonding device::
2481 testpmd> create bonded device (mode) (socket)
2483 For example, to create a bonded device in mode 1 on socket 0::
2485 testpmd> create bonded device 1 0
2486 created new bonded device (port X)
2491 Adds Ethernet device to a Link Bonding device::
2493 testpmd> add bonding slave (slave id) (port id)
2495 For example, to add Ethernet device (port 6) to a Link Bonding device (port 10)::
2497 testpmd> add bonding slave 6 10
2500 remove bonding slave
2501 ~~~~~~~~~~~~~~~~~~~~
2503 Removes an Ethernet slave device from a Link Bonding device::
2505 testpmd> remove bonding slave (slave id) (port id)
2507 For example, to remove Ethernet slave device (port 6) to a Link Bonding device (port 10)::
2509 testpmd> remove bonding slave 6 10
2514 Set the Link Bonding mode of a Link Bonding device::
2516 testpmd> set bonding mode (value) (port id)
2518 For example, to set the bonding mode of a Link Bonding device (port 10) to broadcast (mode 3)::
2520 testpmd> set bonding mode 3 10
2525 Set an Ethernet slave device as the primary device on a Link Bonding device::
2527 testpmd> set bonding primary (slave id) (port id)
2529 For example, to set the Ethernet slave device (port 6) as the primary port of a Link Bonding device (port 10)::
2531 testpmd> set bonding primary 6 10
2536 Set the MAC address of a Link Bonding device::
2538 testpmd> set bonding mac (port id) (mac)
2540 For example, to set the MAC address of a Link Bonding device (port 10) to 00:00:00:00:00:01::

2549 testpmd> set bonding balance_xmit_policy (port_id) (l2|l23|l34)
2551 For example, set a Link Bonding device (port 10) to use a balance policy of layer 3+4 (IP addresses & UDP ports)::
2553 testpmd> set bonding balance_xmit_policy 10 l34
2556 set bonding mon_period
2557 ~~~~~~~~~~~~~~~~~~~~~~
2559 Set the link status monitoring polling period in milliseconds for a bonding device.
2561 This adds support for PMD slave devices which do not support link status interrupts.
2562 When the mon_period is set to a value greater than 0 then all PMD's which do not support
2563 link status ISR will be queried every polling interval to check if their link status has changed::
2565 testpmd> set bonding mon_period (port_id) (value)
2567 For example, to set the link status monitoring polling period of bonded device (port 5) to 150ms::
2569 testpmd> set bonding mon_period 5 150
2572 set bonding lacp dedicated_queue
2573 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

2598 in balance mode with a transmission policy of layer 2+3::
2600 testpmd> show bonding config 9
2602 Balance Xmit Policy: BALANCE_XMIT_POLICY_LAYER23
2604 Active Slaves (3): [1 3 4]
2611 The Register Functions can be used to read from and write to registers on the network card referenced by a port number.
2612 This is mainly useful for debugging purposes.

2655 Set the value of a port register::
2657 testpmd> write reg (port_id) (address) (value)
2659 For example, to clear a register::
2661 testpmd> write reg 0 0xEE00 0x0
2662 port 0 PCI register at offset 0xEE00: 0x00000000 (0)
2667 Set bit field of a port register::
2669 testpmd> write regfield (port_id) (address) (bit_x) (bit_y) (value)

3213 This section details the available filter functions that are available.
3215 Note these functions interface the deprecated legacy filtering framework,
3216 superseded by *rte_flow*. See `Flow rules management`_.

3220 flow_director_filter
3221 ~~~~~~~~~~~~~~~~~~~~
3223 The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.
3225 Four types of filtering are supported which are referred to as Perfect Match, Signature, Perfect-mac-vlan and
3226 Perfect-tunnel filters, the match mode is set by the ``--pkt-filter-mode`` command-line parameter:
3228 * Perfect match filters.
3229 The hardware checks a match between the masked fields of the received packets and the programmed filters.
3230 The masked fields are for IP flow.
3232 * Signature filters.
3233 The hardware checks a match between a hash-based signature of the masked fields of the received packet.
3235 * Perfect-mac-vlan match filters.
3236 The hardware checks a match between the masked fields of the received packets and the programmed filters.
3237 The masked fields are for MAC VLAN flow.
3239 * Perfect-tunnel match filters.
3240 The hardware checks a match between the masked fields of the received packets and the programmed filters.
3241 The masked fields are for tunnel flow.
3243 * Perfect-raw-flow-type match filters.
3244 The hardware checks a match between the masked fields of the received packets and pre-loaded raw (template) packet.
3245 The masked fields are specified by input sets.
3247 The Flow Director filters can match the different fields for different type of packet: flow type, specific input set
3248 per flow type and the flexible payload.
3250 The Flow Director can also mask out parts of all of these fields so that filters
3251 are only applied to certain fields or parts of the fields.
3253 Note that for raw flow type mode the source and destination fields in the
3254 raw packet buffer need to be presented in a reversed order with respect
3255 to the expected received packets.
3256 For example: IP source and destination addresses or TCP/UDP/SCTP
3257 source and destination ports
3259 Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information.

3311 testpmd> flow_director_filter 0 mode IP add flow ipv4-udp src 2.2.2.3 32 \
3312 dst 2.2.2.5 33 tos 2 ttl 40 vlan 0x1 flexbytes (0x88,0x48) \
3313 fwd pf queue 1 fd_id 1
3315 For example, add an ipv4-other flow type filter::
3317 testpmd> flow_director_filter 0 mode IP add flow ipv4-other src 2.2.2.3 \
3318 dst 2.2.2.5 tos 2 proto 20 ttl 40 vlan 0x1 \
3319 flexbytes (0x88,0x48) fwd pf queue 1 fd_id 1
3324 Flush all flow director filters on a device::
3326 testpmd> flush_flow_director (port_id)
3328 Example, to flush all flow director filter on port 0::
3330 testpmd> flush_flow_director 0
3335 Set flow director's input masks::
3337 flow_director_mask (port_id) mode IP vlan (vlan_value) \
3338 src_mask (ipv4_src) (ipv6_src) (src_port) \
3339 dst_mask (ipv4_dst) (ipv6_dst) (dst_port)

3353 FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF 0xFFFF
3355 flow_director_flex_mask
3356 ~~~~~~~~~~~~~~~~~~~~~~~
3358 set masks of flow director's flexible payload based on certain flow type::
3360 testpmd> flow_director_flex_mask (port_id) \
3361 flow (none|ipv4-other|ipv4-frag|ipv4-tcp|ipv4-udp|ipv4-sctp| \
3362 ipv6-other|ipv6-frag|ipv6-tcp|ipv6-udp|ipv6-sctp| \
3363 l2_payload|all) (mask)
3365 Example, to set flow director's flex mask for all flow type on port 0::
3367 testpmd> flow_director_flex_mask 0 flow all \
3368 (0xff,0xff,0,0,0,0,0,0,0,0,0,0,0,0,0,0)
3371 flow_director_flex_payload
3372 ~~~~~~~~~~~~~~~~~~~~~~~~~~
3374 Configure flexible payload selection::
3376 flow_director_flex_payload (port_id) (raw|l2|l3|l4) (config)
3378 For example, to select the first 16 bytes from the offset 4 (bytes) of packet's payload as flexible payload::
3380 testpmd> flow_director_flex_payload 0 l4 \
3381 (4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19)
3386 The Flow Director filters can match the different fields for different type of packet, i.e. specific input set
3387 on per flow type and the flexible payload. This command can be used to change input set for each flow type.
3389 Set the input set for flow director::
3391 set_fdir_input_set (port_id) (ipv4-frag|ipv4-tcp|ipv4-udp|ipv4-sctp| \
3392 ipv4-other|ipv6|ipv6-frag|ipv6-tcp|ipv6-udp|ipv6-sctp|ipv6-other| \
3393 l2_payload|<flow_id>) (ivlan|ethertype|src-ipv4|dst-ipv4|src-ipv6|dst-ipv6| \
3394 ipv4-tos|ipv4-proto|ipv4-ttl|ipv6-tc|ipv6-next-header|ipv6-hop-limits| \
3395 tudp-src-port|udp-dst-port|cp-src-port|tcp-dst-port|sctp-src-port| \
3396 sctp-dst-port|sctp-veri-tag|none) (select|add)
3398 For example to add source IP to FD input set for flow type of ipv4-udp on port 0::
3400 testpmd> set_fdir_input_set 0 ipv4-udp src-ipv4 add
3405 Set different GRE key length for input set::
3407 global_config (port_id) gre-key-len (number in bytes)
3409 For example to set GRE key length for input set to 4 bytes on port 0::
3411 testpmd> global_config 0 gre-key-len 4

3416 Flow rules management
3417 ---------------------
3419 Control of the generic flow API (*rte_flow*) is fully exposed through the
3420 ``flow`` command (validation, creation, destruction, queries and operation
3423 Considering *rte_flow* overlaps with all `Filter Functions`_, using both
3424 features simultaneously may cause undefined side-effects and is therefore
3430 Because the ``flow`` command uses dynamic tokens to handle the large number
3431 of possible flow rules combinations, its behavior differs slightly from
3432 other commands, in particular:
3434 - Pressing *?* or the *<tab>* key displays contextual help for the current
3435 token, not that of the entire command.
3437 - Optional and repeated parameters are supported (provided they are listed
3438 in the contextual help).
3440 The first parameter stands for the operation mode. Possible operations and
3441 their general syntax are described below. They are covered in detail in the
3444 - Check whether a flow rule can be created::
3446 flow validate {port_id}
3447 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3448 pattern {item} [/ {item} [...]] / end
3449 actions {action} [/ {action} [...]] / end
3451 - Create a flow rule::
3453 flow create {port_id}
3454 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3455 pattern {item} [/ {item} [...]] / end
3456 actions {action} [/ {action} [...]] / end
3458 - Destroy specific flow rules::
3460 flow destroy {port_id} rule {rule_id} [...]
3462 - Destroy all flow rules::
3464 flow flush {port_id}
3466 - Query an existing flow rule::
3468 flow query {port_id} {rule_id} {action}
3470 - List existing flow rules sorted by priority, filtered by group
3473 flow list {port_id} [group {group_id}] [...]
3475 - Restrict ingress traffic to the defined flow rules::
3477 flow isolate {port_id} {boolean}
3479 - Dump internal representation information of all flows in hardware::
3481 flow dump {port_id} {output_file}
3483 - List and destroy aged flow rules::
3485 flow aged {port_id} [destroy]
3487 - Tunnel offload - create a tunnel stub::
3489 flow tunnel create {port_id} type {tunnel_type}
3491 - Tunnel offload - destroy a tunnel stub::
3493 flow tunnel destroy {port_id} id {tunnel_id}
3495 - Tunnel offload - list port tunnel stubs::
3497 flow tunnel list {port_id}
3499 Creating a tunnel stub for offload
3500 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3502 ``flow tunnel create`` setup a tunnel stub for tunnel offload flow rules::
3504 flow tunnel create {port_id} type {tunnel_type}
3506 If successful, it will return a tunnel stub ID usable with other commands::
3508 port [...]: flow tunnel #[...] type [...]
3510 Tunnel stub ID is relative to a port.
3512 Destroying tunnel offload stub
3513 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3515 ``flow tunnel destroy`` destroy port tunnel stub::
3517 flow tunnel destroy {port_id} id {tunnel_id}
3519 Listing tunnel offload stubs
3520 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3522 ``flow tunnel list`` list port tunnel offload stubs::
3524 flow tunnel list {port_id}
3526 Validating flow rules
3527 ~~~~~~~~~~~~~~~~~~~~~
3529 ``flow validate`` reports whether a flow rule would be accepted by the
3530 underlying device in its current state but stops short of creating it. It is
3531 bound to ``rte_flow_validate()``::
3533 flow validate {port_id}
3534 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3535 pattern {item} [/ {item} [...]] / end
3536 actions {action} [/ {action} [...]] / end
3538 If successful, it will show::
3542 Otherwise it will show an error message of the form::
3544 Caught error type [...] ([...]): [...]
3546 This command uses the same parameters as ``flow create``, their format is
3547 described in `Creating flow rules`_.
3549 Check whether redirecting any Ethernet packet received on port 0 to RX queue
3550 index 6 is supported::
3552 testpmd> flow validate 0 ingress pattern eth / end
3553 actions queue index 6 / end
3557 Port 0 does not support TCPv6 rules::
3559 testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
3561 Caught error type 9 (specific pattern item): Invalid argument
3567 ``flow create`` validates and creates the specified flow rule. It is bound
3568 to ``rte_flow_create()``::
3570 flow create {port_id}
3571 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3572 [tunnel_set {tunnel_id}] [tunnel_match {tunnel_id}]
3573 pattern {item} [/ {item} [...]] / end
3574 actions {action} [/ {action} [...]] / end
3576 If successful, it will return a flow rule ID usable with other commands::
3578 Flow rule #[...] created
3580 Otherwise it will show an error message of the form::
3582 Caught error type [...] ([...]): [...]
3584 Parameters describe in the following order:
3586 - Attributes (*group*, *priority*, *ingress*, *egress*, *transfer* tokens).
3587 - Tunnel offload specification (tunnel_set, tunnel_match)
3588 - A matching pattern, starting with the *pattern* token and terminated by an
3590 - Actions, starting with the *actions* token and terminated by an *end*
3593 These translate directly to *rte_flow* objects provided as-is to the
3594 underlying functions.
3596 The shortest valid definition only comprises mandatory tokens::
3598 testpmd> flow create 0 pattern end actions end
3600 Note that PMDs may refuse rules that essentially do nothing such as this
3603 **All unspecified object values are automatically initialized to 0.**
3608 These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
3609 specified before the ``pattern`` token.
3611 - ``group {group id}``: priority group.
3612 - ``priority {level}``: priority level within group.
3613 - ``ingress``: rule applies to ingress traffic.
3614 - ``egress``: rule applies to egress traffic.
3615 - ``transfer``: apply rule directly to endpoints found in pattern.
3617 Each instance of an attribute specified several times overrides the previous
3618 value as shown below (group 4 is used)::
3620 testpmd> flow create 0 group 42 group 24 group 4 [...]
3622 Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
3624 While not specifying a direction is an error, some rules may allow both
3627 Most rules affect RX therefore contain the ``ingress`` token::
3629 testpmd> flow create 0 ingress pattern [...]
3634 Indicate tunnel offload rule type
3636 - ``tunnel_set {tunnel_id}``: mark rule as tunnel offload decap_set type.
3637 - ``tunnel_match {tunnel_id}``: mark rule as tunel offload match type.
3642 A matching pattern starts after the ``pattern`` token. It is made of pattern
3643 items and is terminated by a mandatory ``end`` item.
3645 Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
3646 rte_flow_item_type``).
3648 The ``/`` token is used as a separator between pattern items as shown
3651 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
3653 Note that protocol items like these must be stacked from lowest to highest
3654 layer to make sense. For instance, the following rule is either invalid or
3655 unlikely to match any packet::
3657 testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
3659 More information on these restrictions can be found in the *rte_flow*
3662 Several items support additional specification structures, for example
3663 ``ipv4`` allows specifying source and destination addresses as follows::
3665 testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
3666 dst is 10.2.0.0 / end [...]
3668 This rule matches all IPv4 traffic with the specified properties.
3670 In this example, ``src`` and ``dst`` are field names of the underlying
3671 ``struct rte_flow_item_ipv4`` object. All item properties can be specified
3672 in a similar fashion.
3674 The ``is`` token means that the subsequent value must be matched exactly,
3675 and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
3676 accordingly. Possible assignment tokens are:
3678 - ``is``: match value perfectly (with full bit-mask).
3679 - ``spec``: match value according to configured bit-mask.
3680 - ``last``: specify upper bound to establish a range.
3681 - ``mask``: specify bit-mask with relevant bits set to one.
3682 - ``prefix``: generate bit-mask with <prefix-length> most-significant bits set to one.
3684 These yield identical results::
3686 ipv4 src is 10.1.1.1
3690 ipv4 src spec 10.1.1.1 src mask 255.255.255.255
3694 ipv4 src spec 10.1.1.1 src prefix 32
3698 ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
3702 ipv4 src is 10.1.1.1 src last 0 # 0 disables range
3704 Inclusive ranges can be defined with ``last``::
3706 ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
3708 Note that ``mask`` affects both ``spec`` and ``last``::
3710 ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0
3711 # matches 10.1.0.0 to 10.2.255.255
3713 Properties can be modified multiple times::
3715 ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
3719 ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16

3927 A list of actions starts after the ``actions`` token in the same fashion as
3928 `Matching pattern`_; actions are separated by ``/`` tokens and the list is
3929 terminated by a mandatory ``end`` action.
3931 Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
3932 rte_flow_action_type``).
3934 Dropping all incoming UDPv4 packets can be expressed as follows::
3936 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3939 Several actions have configurable properties which must be specified when
3940 there is no valid default value. For example, ``queue`` requires a target
3943 This rule redirects incoming UDPv4 traffic to queue index 6::
3945 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3946 actions queue index 6 / end
3948 While this one could be rejected by PMDs (unspecified queue index)::
3950 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3953 As defined by *rte_flow*, the list is not ordered, all actions of a given
3954 rule are performed simultaneously. These are equivalent::
3956 queue index 6 / void / mark id 42 / end
3960 void / mark id 42 / queue index 6 / end
3962 All actions in a list should have different types, otherwise only the last
3963 action of a given type is taken into account::
3965 queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
3969 drop / drop / drop / end # drop is performed only once
3973 mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
3975 Considering they are performed simultaneously, opposite and overlapping
3976 actions can sometimes be combined when the end result is unambiguous::
3978 drop / queue index 6 / end # drop has no effect
3982 queue index 6 / rss queues 6 7 8 / end # queue has no effect
3986 drop / passthru / end # drop has no effect
3988 Note that PMDs may still refuse such combinations.

4195 Destroying flow rules
4196 ~~~~~~~~~~~~~~~~~~~~~
4198 ``flow destroy`` destroys one or more rules from their rule ID (as returned
4199 by ``flow create``), this command calls ``rte_flow_destroy()`` as many
4200 times as necessary::
4202 flow destroy {port_id} rule {rule_id} [...]
4204 If successful, it will show::
4206 Flow rule #[...] destroyed
4208 It does not report anything for rule IDs that do not exist. The usual error
4209 message is shown when a rule cannot be destroyed::
4211 Caught error type [...] ([...]): [...]
4213 ``flow flush`` destroys all rules on a device and does not take extra
4214 arguments. It is bound to ``rte_flow_flush()``::
4216 flow flush {port_id}
4218 Any errors are reported as above.
4220 Creating several rules and destroying them::
4222 testpmd> flow create 0 ingress pattern eth / ipv6 / end
4223 actions queue index 2 / end
4224 Flow rule #0 created
4225 testpmd> flow create 0 ingress pattern eth / ipv4 / end
4226 actions queue index 3 / end
4227 Flow rule #1 created
4228 testpmd> flow destroy 0 rule 0 rule 1
4229 Flow rule #1 destroyed
4230 Flow rule #0 destroyed
4233 The same result can be achieved using ``flow flush``::
4235 testpmd> flow create 0 ingress pattern eth / ipv6 / end
4236 actions queue index 2 / end
4237 Flow rule #0 created
4238 testpmd> flow create 0 ingress pattern eth / ipv4 / end
4239 actions queue index 3 / end
4240 Flow rule #1 created
4241 testpmd> flow flush 0
4244 Non-existent rule IDs are ignored::
4246 testpmd> flow create 0 ingress pattern eth / ipv6 / end
4247 actions queue index 2 / end
4248 Flow rule #0 created
4249 testpmd> flow create 0 ingress pattern eth / ipv4 / end
4250 actions queue index 3 / end
4251 Flow rule #1 created
4252 testpmd> flow destroy 0 rule 42 rule 10 rule 2
4254 testpmd> flow destroy 0 rule 0
4255 Flow rule #0 destroyed
4261 ``flow query`` queries a specific action of a flow rule having that
4262 ability. Such actions collect information that can be reported using this
4263 command. It is bound to ``rte_flow_query()``::
4265 flow query {port_id} {rule_id} {action}
4267 If successful, it will display either the retrieved data for known actions
4268 or the following message::
4270 Cannot display result for action type [...] ([...])
4272 Otherwise, it will complain either that the rule does not exist or that some
4275 Flow rule #[...] not found
4279 Caught error type [...] ([...]): [...]
4281 Currently only the ``count`` action is supported. This action reports the
4282 number of packets that hit the flow rule and the total number of bytes. Its
4283 output has the following format::
4286 hits_set: [...] # whether "hits" contains a valid value
4287 bytes_set: [...] # whether "bytes" contains a valid value
4288 hits: [...] # number of packets
4289 bytes: [...] # number of bytes
4291 Querying counters for TCPv6 packets redirected to queue 6::
4293 testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
4294 actions queue index 6 / count / end
4295 Flow rule #4 created
4296 testpmd> flow query 0 4 count
4307 ``flow list`` lists existing flow rules sorted by priority and optionally
4308 filtered by group identifiers::
4310 flow list {port_id} [group {group_id}] [...]
4312 This command only fails with the following message if the device does not
4317 Output consists of a header line followed by a short description of each
4318 flow rule, one per line. There is no output at all when no flow rules are
4319 configured on the device::
4321 ID Group Prio Attr Rule
4322 [...] [...] [...] [...] [...]
4324 ``Attr`` column flags:
4326 - ``i`` for ``ingress``.
4327 - ``e`` for ``egress``.
4329 Creating several flow rules and listing them::
4331 testpmd> flow create 0 ingress pattern eth / ipv4 / end
4332 actions queue index 6 / end
4333 Flow rule #0 created
4334 testpmd> flow create 0 ingress pattern eth / ipv6 / end
4335 actions queue index 2 / end
4336 Flow rule #1 created
4337 testpmd> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
4338 actions rss queues 6 7 8 end / end
4339 Flow rule #2 created
4340 testpmd> flow list 0
4341 ID Group Prio Attr Rule
4342 0 0 0 i- ETH IPV4 => QUEUE
4343 1 0 0 i- ETH IPV6 => QUEUE
4344 2 0 5 i- ETH IPV4 UDP => RSS
4347 Rules are sorted by priority (i.e. group ID first, then priority level)::
4349 testpmd> flow list 1
4350 ID Group Prio Attr Rule
4351 0 0 0 i- ETH => COUNT
4352 6 0 500 i- ETH IPV6 TCP => DROP COUNT
4353 5 0 1000 i- ETH IPV6 ICMP => QUEUE
4354 1 24 0 i- ETH IPV4 UDP => QUEUE
4355 4 24 10 i- ETH IPV4 TCP => DROP
4356 3 24 20 i- ETH IPV4 => DROP
4357 2 24 42 i- ETH IPV4 UDP => QUEUE
4358 7 63 0 i- ETH IPV6 UDP VXLAN => MARK QUEUE
4361 Output can be limited to specific groups::
4363 testpmd> flow list 1 group 0 group 63
4364 ID Group Prio Attr Rule
4365 0 0 0 i- ETH => COUNT
4366 6 0 500 i- ETH IPV6 TCP => DROP COUNT
4367 5 0 1000 i- ETH IPV6 ICMP => QUEUE
4368 7 63 0 i- ETH IPV6 UDP VXLAN => MARK QUEUE
4371 Toggling isolated mode
4372 ~~~~~~~~~~~~~~~~~~~~~~
4374 ``flow isolate`` can be used to tell the underlying PMD that ingress traffic
4375 must only be injected from the defined flow rules; that no default traffic
4376 is expected outside those rules and the driver is free to assign more
4377 resources to handle them. It is bound to ``rte_flow_isolate()``::
4379 flow isolate {port_id} {boolean}
4381 If successful, enabling or disabling isolated mode shows either::
4383 Ingress traffic on port [...]
4384 is now restricted to the defined flow rules
4388 Ingress traffic on port [...]
4389 is not restricted anymore to the defined flow rules
4391 Otherwise, in case of error::
4393 Caught error type [...] ([...]): [...]
4395 Mainly due to its side effects, PMDs supporting this mode may not have the
4396 ability to toggle it more than once without reinitializing affected ports
4397 first (e.g. by exiting testpmd).
4399 Enabling isolated mode::
4401 testpmd> flow isolate 0 true
4402 Ingress traffic on port 0 is now restricted to the defined flow rules
4405 Disabling isolated mode::
4407 testpmd> flow isolate 0 false
4408 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
4411 Dumping HW internal information
4412 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4414 ``flow dump`` dumps the hardware's internal representation information of
4415 all flows. It is bound to ``rte_flow_dev_dump()``::
4417 flow dump {port_id} {output_file}
4419 If successful, it will show::
4423 Otherwise, it will complain error occurred::
4425 Caught error type [...] ([...]): [...]
4427 Listing and destroying aged flow rules
4428 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4430 ``flow aged`` simply lists aged flow rules be get from api ``rte_flow_get_aged_flows``,
4431 and ``destroy`` parameter can be used to destroy those flow rules in PMD.
4433 flow aged {port_id} [destroy]
4435 Listing current aged flow rules::
4437 testpmd> flow aged 0
4438 Port 0 total aged flows: 0
4439 testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.14 / end
4440 actions age timeout 5 / queue index 0 / end
4441 Flow rule #0 created
4442 testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.15 / end
4443 actions age timeout 4 / queue index 0 / end
4444 Flow rule #1 created
4445 testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.16 / end
4446 actions age timeout 2 / queue index 0 / end
4447 Flow rule #2 created
4448 testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.17 / end
4449 actions age timeout 3 / queue index 0 / end
4450 Flow rule #3 created
4453 Aged Rules are simply list as command ``flow list {port_id}``, but strip the detail rule
4454 information, all the aged flows are sorted by the longest timeout time. For example, if
4455 those rules be configured in the same time, ID 2 will be the first aged out rule, the next
4456 will be ID 3, ID 1, ID 0::
4458 testpmd> flow aged 0
4459 Port 0 total aged flows: 4
4466 If attach ``destroy`` parameter, the command will destroy all the list aged flow rules.
4468 testpmd> flow aged 0 destroy
4469 Port 0 total aged flows: 4
4476 Flow rule #2 destroyed
4477 Flow rule #3 destroyed
4478 Flow rule #1 destroyed
4479 Flow rule #0 destroyed
4480 4 flows be destroyed
4481 testpmd> flow aged 0
4482 Port 0 total aged flows: 0
4484 Creating shared actions
4485 ~~~~~~~~~~~~~~~~~~~~~~~
4486 ``flow shared_action {port_id} create`` creates shared action with optional
4487 shared action ID. It is bound to ``rte_flow_shared_action_create()``::
4489 flow shared_action {port_id} create [action_id {shared_action_id}]
4490 [ingress] [egress] action {action} / end
4492 If successful, it will show::
4494 Shared action #[...] created
4496 Otherwise, it will complain either that shared action already exists or that
4497 some error occurred::
4499 Shared action #[...] is already assigned, delete it first
4503 Caught error type [...] ([...]): [...]
4505 Create shared rss action with id 100 to queues 1 and 2 on port 0::
4507 testpmd> flow shared_action 0 create action_id 100 \
4508 ingress action rss queues 1 2 end / end
4510 Create shared rss action with id assigned by testpmd to queues 1 and 2 on
4513 testpmd> flow shared_action 0 create action_id \
4514 ingress action rss queues 0 1 end / end
4516 Updating shared actions
4517 ~~~~~~~~~~~~~~~~~~~~~~~
4518 ``flow shared_action {port_id} update`` updates configuration of the shared

4523 flow shared_action {port_id} update {shared_action_id}
4524 action {action} / end
4526 If successful, it will show::
4528 Shared action #[...] updated
4530 Otherwise, it will complain either that shared action not found or that some

4544 Destroying shared actions
4545 ~~~~~~~~~~~~~~~~~~~~~~~~~
4546 ``flow shared_action {port_id} update`` destroys one or more shared actions
4547 from their shared action IDs (as returned by
4548 ``flow shared_action {port_id} create``). It is bound to
4549 ``rte_flow_shared_action_destroy()``::
4551 flow shared_action {port_id} destroy action_id {shared_action_id} [...]
4553 If successful, it will show::
4555 Shared action #[...] destroyed
4557 It does not report anything for shared action IDs that do not exist.
4558 The usual error message is shown when a shared action cannot be destroyed::
4560 Caught error type [...] ([...]): [...]
4562 Destroy shared actions having id 100 & 101::
4564 testpmd> flow shared_action 0 destroy action_id 100 action_id 101
4566 Query shared actions
4567 ~~~~~~~~~~~~~~~~~~~~
4568 ``flow shared_action {port_id} query`` queries the shared action from its
4569 shared action ID (as returned by ``flow shared_action {port_id} create``).
4570 It is bound to ``rte_flow_shared_action_query()``::
4572 flow shared_action {port_id} query {shared_action_id}
4574 Currently only rss shared action supported. If successful, it will show::
4579 Otherwise, it will complain either that shared action not found or that some

4592 Sample QinQ flow rules
4593 ~~~~~~~~~~~~~~~~~~~~~~
4595 Before creating QinQ rule(s) the following commands should be issued to enable QinQ::
4597 testpmd> port stop 0

4600 The above command sets the inner and outer TPID's to 0x8100.
4602 To change the TPID's the following commands should be used::
4604 testpmd> vlan set outer tpid 0xa100 0
4605 testpmd> vlan set inner tpid 0x9100 0
4606 testpmd> port start 0
4608 Validate and create a QinQ rule on port 0 to steer traffic to a VF queue in a VM.

5003 The following sections show functions to load/unload eBPF based filters.
5008 Load an eBPF program as a callback for particular RX/TX queue::
5010 testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)
5012 The available load-flags are:
5014 * ``J``: use JIT generated native code, otherwise BPF interpreter will be used.
5016 * ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.
5022 You'll need clang v3.7 or above to build bpf program you'd like to load
5026 .. code-block:: console
5029 clang -O2 -target bpf -c t1.c
5031 Then to load (and JIT compile) t1.o at RX queue 0, port 1:
5033 .. code-block:: console
5035 testpmd> bpf-load rx 1 0 J ./dpdk.org/examples/bpf/t1.o
5037 To load (not JITed) t1.o at TX queue 0, port 0:
5039 .. code-block:: console
5041 testpmd> bpf-load tx 0 0 - ./dpdk.org/examples/bpf/t1.o
5046 Unload previously loaded eBPF program for particular RX/TX queue::
5048 testpmd> bpf-unload rx|tx (portid) (queueid)
5050 For example to unload BPF filter from TX queue 0, port 0:
5052 .. code-block:: console
5054 testpmd> bpf-unload tx 0 0
