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 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 ./testpmd -n4 -r2 ... -- -i --cmdline-file=/home/ubuntu/flow-create-commands.txt
75 Interactive-mode selected

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.
168 * ``summary``: Brief port summary such as Device Name, Driver Name etc.
170 * ``stats``: RX/TX statistics.
172 * ``xstats``: RX/TX extended NIC statistics.
174 * ``fdir``: Flow Director information and statistics.
176 * ``stat_qmap``: Queue statistics mapping.
178 * ``dcb_tc``: DCB information such as TC mapping.
180 * ``cap``: Supported offload capabilities.
184 .. code-block:: console
186 testpmd> show port info 0
188 ********************* Infos for port 0 *********************
190 MAC address: XX:XX:XX:XX:XX:XX
192 memory allocation on the socket: 0

197 Allmulticast mode: disabled
198 Maximum number of MAC addresses: 64
199 Maximum number of MAC addresses of hash filtering: 0
204 Redirection table size: 512
205 Supported flow types:
225 Display the rss redirection table entry indicated by masks on port X::
227 testpmd> show port (port_id) rss reta (size) (mask0, mask1...)
229 size is used to indicate the hardware supported reta size
234 Display the RSS hash functions and RSS hash key of a port::
236 testpmd> show port (port_id) rss-hash [key]
241 Clear the port statistics for a given port or for all ports::
243 testpmd> clear port (info|stats|xstats|fdir|stat_qmap) (port_id|all)
247 testpmd> clear port stats all
252 Display information for a given port's RX/TX queue::
254 testpmd> show (rxq|txq) info (port_id) (queue_id)
259 Displays the configuration of the application.
260 The configuration comes from the command-line, the runtime or the application defaults::
262 testpmd> show config (rxtx|cores|fwd|txpkts)
264 The available information categories are:
266 * ``rxtx``: RX/TX configuration items.
268 * ``cores``: List of forwarding cores.
270 * ``fwd``: Packet forwarding configuration.
272 * ``txpkts``: Packets to TX configuration.
276 .. code-block:: console
278 testpmd> show config rxtx
280 io packet forwarding - CRC stripping disabled - packets/burst=16
281 nb forwarding cores=2 - nb forwarding ports=1
282 RX queues=1 - RX desc=128 - RX free threshold=0
283 RX threshold registers: pthresh=8 hthresh=8 wthresh=4
284 TX queues=1 - TX desc=512 - TX free threshold=0
285 TX threshold registers: pthresh=36 hthresh=0 wthresh=0
286 TX RS bit threshold=0 - TXQ flags=0x0
291 Set the packet forwarding mode::
293 testpmd> set fwd (io|mac|macswap|flowgen| \
294 rxonly|txonly|csum|icmpecho|noisy) (""|retry)
296 ``retry`` can be specified for forwarding engines except ``rx_only``.
298 The available information categories are:
300 * ``io``: Forwards packets "as-is" in I/O mode.
301 This is the fastest possible forwarding operation as it does not access packets data.
302 This is the default mode.
304 * ``mac``: Changes the source and the destination Ethernet addresses of packets before forwarding them.
305 Default application behaviour is to set source Ethernet address to that of the transmitting interface, and destination
306 address to a dummy value (set during init). The user may specify a target destination Ethernet address via the 'eth-peer' or
307 'eth-peer-configfile' command-line options. It is not currently possible to specify a specific source Ethernet address.
309 * ``macswap``: MAC swap forwarding mode.
310 Swaps the source and the destination Ethernet addresses of packets before forwarding them.
312 * ``flowgen``: Multi-flow generation mode.
313 Originates a number of flows (with varying destination IP addresses), and terminate receive traffic.
315 * ``rxonly``: Receives packets but doesn't transmit them.
317 * ``txonly``: Generates and transmits packets without receiving any.
319 * ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet.
321 * ``icmpecho``: Receives a burst of packets, lookup for ICMP echo requests and, if any, send back ICMP echo replies.
323 * ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX. Requires ``CONFIG_RTE_LIBRTE_IEEE1588=y``.
325 * ``softnic``: Demonstrates the softnic forwarding operation. In this mode, packet forwarding is
326 similar to I/O mode except for the fact that packets are loopback to the softnic ports only. Therefore, portmask parameter should be set to softnic port only. The various software based custom NIC pipelines specified through the softnic firmware (DPDK packet framework script) can be tested in this mode. Furthermore, it allows to build 5-level hierarchical QoS scheduler as a default option that can be enabled through CLI once testpmd application is initialised. The user can modify the default scheduler hierarchy or can specify the new QoS Scheduler hierarchy through CLI. Requires ``CONFIG_RTE_LIBRTE_PMD_SOFTNIC=y``.
328 * ``noisy``: Noisy neighbour simulation.
329 Simulate more realistic behavior of a guest machine engaged in receiving
330 and sending packets performing Virtual Network Function (VNF).

433 Configuration Functions
434 -----------------------
436 The testpmd application can be configured from the runtime as well as from the command-line.
438 This section details the available configuration functions that are available.
442 Configuration changes only become active when forwarding is started/restarted.
447 Reset forwarding to the default configuration::
454 Set the debug verbosity level::
456 testpmd> set verbose (level)
458 Available levels are as following:
460 * ``0`` silent except for error.
461 * ``1`` fully verbose except for Tx packets.
462 * ``2`` fully verbose except for Rx packets.
463 * ``> 2`` fully verbose.
468 Set the log level for a log type::
470 testpmd> set log global|(type) (level)
474 * ``type`` is the log name.
476 * ``level`` is the log level.
478 For example, to change the global log level::
479 testpmd> set log global (level)
481 Regexes can also be used for type. To change log level of user1, user2 and user3::
482 testpmd> set log user[1-3] (level)
487 Set the number of ports used by the application:
491 This is equivalent to the ``--nb-ports`` command-line option.
496 Set the number of cores used by the application::
498 testpmd> set nbcore (num)
500 This is equivalent to the ``--nb-cores`` command-line option.
504 The number of cores used must not be greater than number of ports used multiplied by the number of queues per port.
509 Set the forwarding cores hexadecimal mask::
511 testpmd> set coremask (mask)
513 This is equivalent to the ``--coremask`` command-line option.
517 The master lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
522 Set the forwarding ports hexadecimal mask::
524 testpmd> set portmask (mask)
526 This is equivalent to the ``--portmask`` command-line option.
531 Set number of packets per burst::
533 testpmd> set burst (num)
535 This is equivalent to the ``--burst command-line`` option.
537 When retry is enabled, the transmit delay time and number of retries can also be set::
539 testpmd> set burst tx delay (microseconds) retry (num)
544 Set the length of each segment of the TX-ONLY packets or length of packet for FLOWGEN mode::
546 testpmd> set txpkts (x[,y]*)
548 Where x[,y]* represents a CSV list of values, without white space.
553 Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes::
555 testpmd> set txsplit (off|on|rand)
559 * ``off`` disable packet copy & split for CSUM mode.
561 * ``on`` split outgoing packet into multiple segments. Size of each segment
562 and number of segments per packet is determined by ``set txpkts`` command
565 * ``rand`` same as 'on', but number of segments per each packet is a random value between 1 and total number of segments.
570 Set the list of forwarding cores::
572 testpmd> set corelist (x[,y]*)
574 For example, to change the forwarding cores:
576 .. code-block:: console
578 testpmd> set corelist 3,1
579 testpmd> show config fwd
581 io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled
582 Logical Core 3 (socket 0) forwards packets on 1 streams:
583 RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
584 Logical Core 1 (socket 0) forwards packets on 1 streams:
585 RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
589 The cores are used in the same order as specified on the command line.
594 Set the list of forwarding ports::
596 testpmd> set portlist (x[,y]*)
598 For example, to change the port forwarding:
600 .. code-block:: console
602 testpmd> set portlist 0,2,1,3
603 testpmd> show config fwd
605 io packet forwarding - ports=4 - cores=1 - streams=4
606 Logical Core 3 (socket 0) forwards packets on 4 streams:
607 RX P=0/Q=0 (socket 0) -> TX P=2/Q=0 (socket 0) peer=02:00:00:00:00:01
608 RX P=2/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
609 RX P=1/Q=0 (socket 0) -> TX P=3/Q=0 (socket 0) peer=02:00:00:00:00:03
610 RX P=3/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:02
615 Select how to retrieve new ports created after "port attach" command::
617 testpmd> set port setup on (iterator|event)
619 For each new port, a setup is done.
620 It will find the probed ports via RTE_ETH_FOREACH_MATCHING_DEV loop
621 in iterator mode, or via RTE_ETH_EVENT_NEW in event mode.

886 transmitting a packet using the ``csum`` forwarding engine::
888 testpmd> csum set (ip|udp|tcp|sctp|outer-ip|outer-udp) (hw|sw) (port_id)
892 * ``ip|udp|tcp|sctp`` always relate to the inner layer.
894 * ``outer-ip`` relates to the outer IP layer (only for IPv4) in the case where the packet is recognized
895 as a tunnel packet by the forwarding engine (vxlan, gre and ipip are
896 supported). See also the ``csum parse-tunnel`` command.
898 * ``outer-udp`` relates to the outer UDP layer in the case where the packet is recognized
899 as a tunnel packet by the forwarding engine (vxlan, vxlan-gpe are
900 supported). See also the ``csum parse-tunnel`` command.
904 Check the NIC Datasheet for hardware limits.

912 queue_start_index (value) queue_num (value)
914 Set flowtype mapping on a RSS queue region on a port::
916 testpmd> set port (port_id) queue-region region_id (value) flowtype (value)
920 * For the flowtype(pctype) of packet,the specific index for each type has
921 been defined in file i40e_type.h as enum i40e_filter_pctype.
923 Set user priority mapping on a RSS queue region on a port::
925 testpmd> set port (port_id) queue-region UP (value) region_id (value)
927 Flush all queue region related configuration on a port::
929 testpmd> set port (port_id) queue-region flush (on|off)
933 * "on"is just an enable function which server for other configuration,
934 it is for all configuration about queue region from up layer,
935 at first will only keep in DPDK softwarestored in driver,
936 only after "flush on", it commit all configuration to HW.
937 "off" is just clean all configuration about queue region just now,
938 and restore all to DPDK i40e driver default config when start up.
940 Show all queue region related configuration info on a port::
942 testpmd> show port (port_id) queue-region
946 Queue region only support on PF by now, so these command is
947 only for configuration of queue region on PF port.
952 Define how tunneled packets should be handled by the csum forward
955 testpmd> csum parse-tunnel (on|off) (tx_port_id)
957 If enabled, the csum forward engine will try to recognize supported
958 tunnel headers (vxlan, gre, ipip).
960 If disabled, treat tunnel packets as non-tunneled packets (a inner
961 header is handled as a packet payload).
965 The port argument is the TX port like in the ``csum set`` command.
969 Consider a packet in packet like the following::
971 eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in
973 * If parse-tunnel is enabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
974 command relate to the inner headers (here ``ipv4_in`` and ``tcp_in``), and the
975 ``outer-ip|outer-udp`` parameter relates to the outer headers (here ``ipv4_out`` and ``udp_out``).
977 * If parse-tunnel is disabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
978 command relate to the outer headers, here ``ipv4_out`` and ``udp_out``.
983 Display tx checksum offload configuration::
985 testpmd> csum show (port_id)
990 Enable TCP Segmentation Offload (TSO) in the ``csum`` forwarding engine::
992 testpmd> tso set (segsize) (port_id)
996 Check the NIC datasheet for hardware limits.
1001 Display the status of TCP Segmentation Offload::
1003 testpmd> tso show (port_id)
1008 Enable or disable GRO in ``csum`` forwarding engine::
1010 testpmd> set port <port_id> gro on|off
1012 If enabled, the csum forwarding engine will perform GRO on the TCP/IPv4
1013 packets received from the given port.
1015 If disabled, packets received from the given port won't be performed
1016 GRO. By default, GRO is disabled for all ports.
1020 When enable GRO for a port, TCP/IPv4 packets received from the port
1021 will be performed GRO. After GRO, all merged packets have bad
1022 checksums, since the GRO library doesn't re-calculate checksums for
1023 the merged packets. Therefore, if users want the merged packets to
1024 have correct checksums, please select HW IP checksum calculation and
1025 HW TCP checksum calculation for the port which the merged packets are
1031 Display GRO configuration for a given port::
1033 testpmd> show port <port_id> gro
1038 Set the cycle to flush the GROed packets from reassembly tables::
1040 testpmd> set gro flush <cycles>
1042 When enable GRO, the csum forwarding engine performs GRO on received
1043 packets, and the GROed packets are stored in reassembly tables. Users
1044 can use this command to determine when the GROed packets are flushed
1045 from the reassembly tables.
1047 The ``cycles`` is measured in GRO operation times. The csum forwarding
1048 engine flushes the GROed packets from the tables every ``cycles`` GRO
1051 By default, the value of ``cycles`` is 1, which means flush GROed packets
1052 from the reassembly tables as soon as one GRO operation finishes. The value
1053 of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``.
1055 Please note that the large value of ``cycles`` may cause the poor TCP/IP
1056 stack performance. Because the GROed packets are delayed to arrive the
1057 stack, thus causing more duplicated ACKs and TCP retransmissions.
1062 Toggle per-port GSO support in ``csum`` forwarding engine::
1064 testpmd> set port <port_id> gso on|off
1066 If enabled, the csum forwarding engine will perform GSO on supported IPv4
1067 packets, transmitted on the given port.
1069 If disabled, packets transmitted on the given port will not undergo GSO.
1070 By default, GSO is disabled for all ports.
1074 When GSO is enabled on a port, supported IPv4 packets transmitted on that
1075 port undergo GSO. Afterwards, the segmented packets are represented by
1076 multi-segment mbufs; however, the csum forwarding engine doesn't calculation
1077 of checksums for GSO'd segments in SW. As a result, if users want correct
1078 checksums in GSO segments, they should enable HW checksum calculation for
1081 For example, HW checksum calculation for VxLAN GSO'd packets may be enabled
1082 by setting the following options in the csum forwarding engine:
1084 testpmd> csum set outer_ip hw <port_id>
1086 testpmd> csum set ip hw <port_id>
1088 testpmd> csum set tcp hw <port_id>
1090 UDP GSO is the same as IP fragmentation, which treats the UDP header
1091 as the payload and does not modify it during segmentation. That is,
1092 after UDP GSO, only the first output fragment has the original UDP
1093 header. Therefore, users need to enable HW IP checksum calculation
1094 and SW UDP checksum calculation for GSO-enabled ports, if they want
1095 correct checksums for UDP/IPv4 packets.
1100 Set the maximum GSO segment size (measured in bytes), which includes the
1101 packet header and the packet payload for GSO-enabled ports (global)::

1675 flow rule using the action mplsoudp_encap will use the last configuration set.
1676 To have a different encapsulation header, one of those commands must be called
1677 before the flow rule creation.
1679 Config MPLSoUDP Decap outer layers
1680 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1682 Configure the outer layer to decapsulate MPLSoUDP packet::
1684 set mplsoudp_decap ip-version (ipv4|ipv6)
1685 set mplsoudp_decap-with-vlan ip-version (ipv4|ipv6)
1687 Those command will set an internal configuration inside testpmd, any following
1688 flow rule using the action mplsoudp_decap will use the last configuration set.
1689 To have a different decapsulation header, one of those commands must be called
1690 before the flow rule creation.
1695 The following sections show functions for configuring ports.
1699 Port configuration changes only become active when forwarding is started/restarted.
1704 Attach a port specified by pci address or virtual device args::
1706 testpmd> port attach (identifier)
1708 To attach a new pci device, the device should be recognized by kernel first.
1709 Then it should be moved under DPDK management.
1710 Finally the port can be attached to testpmd.
1712 For example, to move a pci device using ixgbe under DPDK management:
1714 .. code-block:: console
1716 # Check the status of the available devices.
1717 ./usertools/dpdk-devbind.py --status
1719 Network devices using DPDK-compatible driver

1723 Network devices using kernel driver
1724 ===================================
1725 0000:0a:00.0 '82599ES 10-Gigabit' if=eth2 drv=ixgbe unused=
1728 # Bind the device to igb_uio.
1729 sudo ./usertools/dpdk-devbind.py -b igb_uio 0000:0a:00.0
1732 # Recheck the status of the devices.
1733 ./usertools/dpdk-devbind.py --status

1735 ============================================
1736 0000:0a:00.0 '82599ES 10-Gigabit' drv=igb_uio unused=
1738 To attach a port created by virtual device, above steps are not needed.
1740 For example, to attach a port whose pci address is 0000:0a:00.0.
1742 .. code-block:: console
1744 testpmd> port attach 0000:0a:00.0
1745 Attaching a new port...
1746 EAL: PCI device 0000:0a:00.0 on NUMA socket -1
1747 EAL: probe driver: 8086:10fb rte_ixgbe_pmd
1748 EAL: PCI memory mapped at 0x7f83bfa00000
1749 EAL: PCI memory mapped at 0x7f83bfa80000
1750 PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
1751 PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
1752 Port 0 is attached. Now total ports is 1
1755 For example, to attach a port created by pcap PMD.
1757 .. code-block:: console
1759 testpmd> port attach net_pcap0
1760 Attaching a new port...
1761 PMD: Initializing pmd_pcap for net_pcap0
1762 PMD: Creating pcap-backed ethdev on numa socket 0
1763 Port 0 is attached. Now total ports is 1
1766 In this case, identifier is ``net_pcap0``.
1767 This identifier format is the same as ``--vdev`` format of DPDK applications.
1769 For example, to re-attach a bonded port which has been previously detached,
1770 the mode and slave parameters must be given.
1772 .. code-block:: console
1774 testpmd> port attach net_bond_0,mode=0,slave=1
1775 Attaching a new port...
1776 EAL: Initializing pmd_bond for net_bond_0
1777 EAL: Create bonded device net_bond_0 on port 0 in mode 0 on socket 0.
1778 Port 0 is attached. Now total ports is 1
1785 Detach a specific port::
1787 testpmd> port detach (port_id)
1789 Before detaching a port, the port should be stopped and closed.
1791 For example, to detach a pci device port 0.
1793 .. code-block:: console
1795 testpmd> port stop 0
1798 testpmd> port close 0
1802 testpmd> port detach 0
1804 EAL: PCI device 0000:0a:00.0 on NUMA socket -1
1805 EAL: remove driver: 8086:10fb rte_ixgbe_pmd
1806 EAL: PCI memory unmapped at 0x7f83bfa00000
1807 EAL: PCI memory unmapped at 0x7f83bfa80000
1811 For example, to detach a virtual device port 0.
1813 .. code-block:: console
1815 testpmd> port stop 0
1818 testpmd> port close 0
1822 testpmd> port detach 0
1824 PMD: Closing pcap ethdev on numa socket 0
1825 Port 'net_pcap0' is detached. Now total ports is 0
1828 To remove a pci device completely from the system, first detach the port from testpmd.
1829 Then the device should be moved under kernel management.
1830 Finally the device can be removed using kernel pci hotplug functionality.
1832 For example, to move a pci device under kernel management:
1834 .. code-block:: console
1836 sudo ./usertools/dpdk-devbind.py -b ixgbe 0000:0a:00.0
1838 ./usertools/dpdk-devbind.py --status

2149 create bonded device
2150 ~~~~~~~~~~~~~~~~~~~~
2152 Create a new bonding device::
2154 testpmd> create bonded device (mode) (socket)
2156 For example, to create a bonded device in mode 1 on socket 0::
2158 testpmd> create bonded device 1 0
2159 created new bonded device (port X)
2164 Adds Ethernet device to a Link Bonding device::
2166 testpmd> add bonding slave (slave id) (port id)
2168 For example, to add Ethernet device (port 6) to a Link Bonding device (port 10)::
2170 testpmd> add bonding slave 6 10

2230 ~~~~~~~~~~~~~~~~~~~~~~
2232 Set the link status monitoring polling period in milliseconds for a bonding device.
2234 This adds support for PMD slave devices which do not support link status interrupts.
2235 When the mon_period is set to a value greater than 0 then all PMD's which do not support
2236 link status ISR will be queried every polling interval to check if their link status has changed::
2238 testpmd> set bonding mon_period (port_id) (value)
2240 For example, to set the link status monitoring polling period of bonded device (port 5) to 150ms::

2273 testpmd> show bonding config 9
2275 Balance Xmit Policy: BALANCE_XMIT_POLICY_LAYER23
2277 Active Slaves (3): [1 3 4]
2284 The Register Functions can be used to read from and write to registers on the network card referenced by a port number.
2285 This is mainly useful for debugging purposes.
2286 Reference should be made to the appropriate datasheet for the network card for details on the register addresses
2287 and fields that can be accessed.
2292 Display the value of a port register::
2294 testpmd> read reg (port_id) (address)

2320 For example, reading the lowest bit from the register in the example above::
2322 testpmd> read regbit 0 0xEE00 0
2323 port 0 PCI register at offset 0xEE00: bit 0=1
2328 Set the value of a port register::
2330 testpmd> write reg (port_id) (address) (value)
2332 For example, to clear a register::
2334 testpmd> write reg 0 0xEE00 0x0
2335 port 0 PCI register at offset 0xEE00: 0x00000000 (0)
2340 Set bit field of a port register::
2342 testpmd> write regfield (port_id) (address) (bit_x) (bit_y) (value)
2344 For example, writing to the register cleared in the example above::

3034 .. _testpmd_flow_director:
3036 flow_director_filter
3037 ~~~~~~~~~~~~~~~~~~~~
3039 The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.
3041 Four types of filtering are supported which are referred to as Perfect Match, Signature, Perfect-mac-vlan and
3042 Perfect-tunnel filters, the match mode is set by the ``--pkt-filter-mode`` command-line parameter:
3044 * Perfect match filters.
3045 The hardware checks a match between the masked fields of the received packets and the programmed filters.
3046 The masked fields are for IP flow.
3048 * Signature filters.
3049 The hardware checks a match between a hash-based signature of the masked fields of the received packet.
3051 * Perfect-mac-vlan match filters.
3052 The hardware checks a match between the masked fields of the received packets and the programmed filters.
3053 The masked fields are for MAC VLAN flow.
3055 * Perfect-tunnel match filters.
3056 The hardware checks a match between the masked fields of the received packets and the programmed filters.
3057 The masked fields are for tunnel flow.
3059 * Perfect-raw-flow-type match filters.
3060 The hardware checks a match between the masked fields of the received packets and pre-loaded raw (template) packet.
3061 The masked fields are specified by input sets.
3063 The Flow Director filters can match the different fields for different type of packet: flow type, specific input set
3064 per flow type and the flexible payload.
3066 The Flow Director can also mask out parts of all of these fields so that filters
3067 are only applied to certain fields or parts of the fields.
3069 Note that for raw flow type mode the source and destination fields in the
3070 raw packet buffer need to be presented in a reversed order with respect
3071 to the expected received packets.
3072 For example: IP source and destination addresses or TCP/UDP/SCTP
3073 source and destination ports
3075 Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information.

3196 testpmd> flow_director_flex_payload 0 l4 \
3197 (4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19)
3199 get_sym_hash_ena_per_port
3200 ~~~~~~~~~~~~~~~~~~~~~~~~~
3202 Get symmetric hash enable configuration per port::
3204 get_sym_hash_ena_per_port (port_id)
3206 For example, to get symmetric hash enable configuration of port 1::
3208 testpmd> get_sym_hash_ena_per_port 1
3210 set_sym_hash_ena_per_port
3211 ~~~~~~~~~~~~~~~~~~~~~~~~~
3213 Set symmetric hash enable configuration per port to enable or disable::

3217 For example, to set symmetric hash enable configuration of port 1 to enable::
3219 testpmd> set_sym_hash_ena_per_port 1 enable
3221 get_hash_global_config
3222 ~~~~~~~~~~~~~~~~~~~~~~
3224 Get the global configurations of hash filters::

3266 The Flow Director filters can match the different fields for different type of packet, i.e. specific input set
3267 on per flow type and the flexible payload. This command can be used to change input set for each flow type.

3294 .. _testpmd_rte_flow:
3296 Flow rules management
3297 ---------------------
3299 Control of the generic flow API (*rte_flow*) is fully exposed through the
3300 ``flow`` command (validation, creation, destruction, queries and operation
3303 Considering *rte_flow* overlaps with all `Filter Functions`_, using both
3304 features simultaneously may cause undefined side-effects and is therefore
3310 Because the ``flow`` command uses dynamic tokens to handle the large number
3311 of possible flow rules combinations, its behavior differs slightly from
3312 other commands, in particular:
3314 - Pressing *?* or the *<tab>* key displays contextual help for the current
3315 token, not that of the entire command.
3317 - Optional and repeated parameters are supported (provided they are listed
3318 in the contextual help).
3320 The first parameter stands for the operation mode. Possible operations and
3321 their general syntax are described below. They are covered in detail in the
3324 - Check whether a flow rule can be created::
3326 flow validate {port_id}
3327 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3328 pattern {item} [/ {item} [...]] / end
3329 actions {action} [/ {action} [...]] / end
3331 - Create a flow rule::
3333 flow create {port_id}
3334 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3335 pattern {item} [/ {item} [...]] / end
3336 actions {action} [/ {action} [...]] / end
3338 - Destroy specific flow rules::
3340 flow destroy {port_id} rule {rule_id} [...]
3342 - Destroy all flow rules::
3344 flow flush {port_id}
3346 - Query an existing flow rule::
3348 flow query {port_id} {rule_id} {action}
3350 - List existing flow rules sorted by priority, filtered by group
3353 flow list {port_id} [group {group_id}] [...]
3355 - Restrict ingress traffic to the defined flow rules::
3357 flow isolate {port_id} {boolean}
3359 Validating flow rules
3360 ~~~~~~~~~~~~~~~~~~~~~
3362 ``flow validate`` reports whether a flow rule would be accepted by the
3363 underlying device in its current state but stops short of creating it. It is
3364 bound to ``rte_flow_validate()``::
3366 flow validate {port_id}
3367 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3368 pattern {item} [/ {item} [...]] / end
3369 actions {action} [/ {action} [...]] / end
3371 If successful, it will show::
3375 Otherwise it will show an error message of the form::
3377 Caught error type [...] ([...]): [...]
3379 This command uses the same parameters as ``flow create``, their format is
3380 described in `Creating flow rules`_.
3382 Check whether redirecting any Ethernet packet received on port 0 to RX queue
3383 index 6 is supported::
3385 testpmd> flow validate 0 ingress pattern eth / end
3386 actions queue index 6 / end
3390 Port 0 does not support TCPv6 rules::
3392 testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
3394 Caught error type 9 (specific pattern item): Invalid argument
3400 ``flow create`` validates and creates the specified flow rule. It is bound
3401 to ``rte_flow_create()``::
3403 flow create {port_id}
3404 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3405 pattern {item} [/ {item} [...]] / end
3406 actions {action} [/ {action} [...]] / end
3408 If successful, it will return a flow rule ID usable with other commands::
3410 Flow rule #[...] created
3412 Otherwise it will show an error message of the form::
3414 Caught error type [...] ([...]): [...]
3416 Parameters describe in the following order:
3418 - Attributes (*group*, *priority*, *ingress*, *egress*, *transfer* tokens).
3419 - A matching pattern, starting with the *pattern* token and terminated by an
3421 - Actions, starting with the *actions* token and terminated by an *end*
3424 These translate directly to *rte_flow* objects provided as-is to the
3425 underlying functions.
3427 The shortest valid definition only comprises mandatory tokens::
3429 testpmd> flow create 0 pattern end actions end
3431 Note that PMDs may refuse rules that essentially do nothing such as this
3434 **All unspecified object values are automatically initialized to 0.**
3439 These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
3440 specified before the ``pattern`` token.
3442 - ``group {group id}``: priority group.
3443 - ``priority {level}``: priority level within group.
3444 - ``ingress``: rule applies to ingress traffic.
3445 - ``egress``: rule applies to egress traffic.
3446 - ``transfer``: apply rule directly to endpoints found in pattern.
3448 Each instance of an attribute specified several times overrides the previous
3449 value as shown below (group 4 is used)::
3451 testpmd> flow create 0 group 42 group 24 group 4 [...]
3453 Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
3455 While not specifying a direction is an error, some rules may allow both
3458 Most rules affect RX therefore contain the ``ingress`` token::
3460 testpmd> flow create 0 ingress pattern [...]
3465 A matching pattern starts after the ``pattern`` token. It is made of pattern
3466 items and is terminated by a mandatory ``end`` item.
3468 Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
3469 rte_flow_item_type``).
3471 The ``/`` token is used as a separator between pattern items as shown
3474 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
3476 Note that protocol items like these must be stacked from lowest to highest
3477 layer to make sense. For instance, the following rule is either invalid or
3478 unlikely to match any packet::
3480 testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
3482 More information on these restrictions can be found in the *rte_flow*
3485 Several items support additional specification structures, for example
3486 ``ipv4`` allows specifying source and destination addresses as follows::
3488 testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
3489 dst is 10.2.0.0 / end [...]
3491 This rule matches all IPv4 traffic with the specified properties.
3493 In this example, ``src`` and ``dst`` are field names of the underlying
3494 ``struct rte_flow_item_ipv4`` object. All item properties can be specified
3495 in a similar fashion.
3497 The ``is`` token means that the subsequent value must be matched exactly,
3498 and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
3499 accordingly. Possible assignment tokens are:
3501 - ``is``: match value perfectly (with full bit-mask).
3502 - ``spec``: match value according to configured bit-mask.
3503 - ``last``: specify upper bound to establish a range.
3504 - ``mask``: specify bit-mask with relevant bits set to one.
3505 - ``prefix``: generate bit-mask with <prefix-length> most-significant bits set to one.
3507 These yield identical results::
3509 ipv4 src is 10.1.1.1
3513 ipv4 src spec 10.1.1.1 src mask 255.255.255.255
3517 ipv4 src spec 10.1.1.1 src prefix 32
3521 ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
3525 ipv4 src is 10.1.1.1 src last 0 # 0 disables range
3527 Inclusive ranges can be defined with ``last``::
3529 ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
3531 Note that ``mask`` affects both ``spec`` and ``last``::
3533 ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0
3534 # matches 10.1.0.0 to 10.2.255.255
3536 Properties can be modified multiple times::
3538 ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
3542 ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16

3738 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3739 actions queue index 6 / end
3741 While this one could be rejected by PMDs (unspecified queue index)::
3743 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3746 As defined by *rte_flow*, the list is not ordered, all actions of a given
3747 rule are performed simultaneously. These are equivalent::
3749 queue index 6 / void / mark id 42 / end
3753 void / mark id 42 / queue index 6 / end
3755 All actions in a list should have different types, otherwise only the last
3756 action of a given type is taken into account::
3758 queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
3762 drop / drop / drop / end # drop is performed only once
3766 mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
3768 Considering they are performed simultaneously, opposite and overlapping
3769 actions can sometimes be combined when the end result is unambiguous::
3771 drop / queue index 6 / end # drop has no effect
3775 queue index 6 / rss queues 6 7 8 / end # queue has no effect
3779 drop / passthru / end # drop has no effect
3781 Note that PMDs may still refuse such combinations.

3960 Destroying flow rules
3961 ~~~~~~~~~~~~~~~~~~~~~
3963 ``flow destroy`` destroys one or more rules from their rule ID (as returned
3964 by ``flow create``), this command calls ``rte_flow_destroy()`` as many
3965 times as necessary::
3967 flow destroy {port_id} rule {rule_id} [...]
3969 If successful, it will show::
3971 Flow rule #[...] destroyed
3973 It does not report anything for rule IDs that do not exist. The usual error
3974 message is shown when a rule cannot be destroyed::
3976 Caught error type [...] ([...]): [...]
3978 ``flow flush`` destroys all rules on a device and does not take extra
3979 arguments. It is bound to ``rte_flow_flush()``::
3981 flow flush {port_id}
3983 Any errors are reported as above.
3985 Creating several rules and destroying them::
3987 testpmd> flow create 0 ingress pattern eth / ipv6 / end
3988 actions queue index 2 / end
3989 Flow rule #0 created
3990 testpmd> flow create 0 ingress pattern eth / ipv4 / end
3991 actions queue index 3 / end
3992 Flow rule #1 created
3993 testpmd> flow destroy 0 rule 0 rule 1
3994 Flow rule #1 destroyed
3995 Flow rule #0 destroyed
3998 The same result can be achieved using ``flow flush``::
4000 testpmd> flow create 0 ingress pattern eth / ipv6 / end
4001 actions queue index 2 / end
4002 Flow rule #0 created
4003 testpmd> flow create 0 ingress pattern eth / ipv4 / end
4004 actions queue index 3 / end
4005 Flow rule #1 created
4006 testpmd> flow flush 0
4009 Non-existent rule IDs are ignored::
4011 testpmd> flow create 0 ingress pattern eth / ipv6 / end
4012 actions queue index 2 / end
4013 Flow rule #0 created
4014 testpmd> flow create 0 ingress pattern eth / ipv4 / end
4015 actions queue index 3 / end
4016 Flow rule #1 created
4017 testpmd> flow destroy 0 rule 42 rule 10 rule 2
4019 testpmd> flow destroy 0 rule 0
4020 Flow rule #0 destroyed
4026 ``flow query`` queries a specific action of a flow rule having that
4027 ability. Such actions collect information that can be reported using this
4028 command. It is bound to ``rte_flow_query()``::
4030 flow query {port_id} {rule_id} {action}
4032 If successful, it will display either the retrieved data for known actions
4033 or the following message::
4035 Cannot display result for action type [...] ([...])
4037 Otherwise, it will complain either that the rule does not exist or that some
4040 Flow rule #[...] not found
4044 Caught error type [...] ([...]): [...]
4046 Currently only the ``count`` action is supported. This action reports the
4047 number of packets that hit the flow rule and the total number of bytes. Its
4048 output has the following format::
4051 hits_set: [...] # whether "hits" contains a valid value
4052 bytes_set: [...] # whether "bytes" contains a valid value
4053 hits: [...] # number of packets
4054 bytes: [...] # number of bytes
4056 Querying counters for TCPv6 packets redirected to queue 6::
4058 testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
4059 actions queue index 6 / count / end
4060 Flow rule #4 created
4061 testpmd> flow query 0 4 count
4072 ``flow list`` lists existing flow rules sorted by priority and optionally
4073 filtered by group identifiers::
4075 flow list {port_id} [group {group_id}] [...]
4077 This command only fails with the following message if the device does not
4082 Output consists of a header line followed by a short description of each
4083 flow rule, one per line. There is no output at all when no flow rules are
4084 configured on the device::
4086 ID Group Prio Attr Rule
4087 [...] [...] [...] [...] [...]
4089 ``Attr`` column flags:
4091 - ``i`` for ``ingress``.
4092 - ``e`` for ``egress``.
4094 Creating several flow rules and listing them::
4096 testpmd> flow create 0 ingress pattern eth / ipv4 / end
4097 actions queue index 6 / end
4098 Flow rule #0 created
4099 testpmd> flow create 0 ingress pattern eth / ipv6 / end
4100 actions queue index 2 / end
4101 Flow rule #1 created
4102 testpmd> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
4103 actions rss queues 6 7 8 end / end
4104 Flow rule #2 created
4105 testpmd> flow list 0
4106 ID Group Prio Attr Rule
4107 0 0 0 i- ETH IPV4 => QUEUE
4108 1 0 0 i- ETH IPV6 => QUEUE
4109 2 0 5 i- ETH IPV4 UDP => RSS
4112 Rules are sorted by priority (i.e. group ID first, then priority level)::
4114 testpmd> flow list 1
4115 ID Group Prio Attr Rule
4116 0 0 0 i- ETH => COUNT
4117 6 0 500 i- ETH IPV6 TCP => DROP COUNT
4118 5 0 1000 i- ETH IPV6 ICMP => QUEUE
4119 1 24 0 i- ETH IPV4 UDP => QUEUE
4120 4 24 10 i- ETH IPV4 TCP => DROP
4121 3 24 20 i- ETH IPV4 => DROP
4122 2 24 42 i- ETH IPV4 UDP => QUEUE
4123 7 63 0 i- ETH IPV6 UDP VXLAN => MARK QUEUE
4126 Output can be limited to specific groups::
4128 testpmd> flow list 1 group 0 group 63
4129 ID Group Prio Attr Rule
4130 0 0 0 i- ETH => COUNT
4131 6 0 500 i- ETH IPV6 TCP => DROP COUNT
4132 5 0 1000 i- ETH IPV6 ICMP => QUEUE
4133 7 63 0 i- ETH IPV6 UDP VXLAN => MARK QUEUE
4136 Toggling isolated mode
4137 ~~~~~~~~~~~~~~~~~~~~~~
4139 ``flow isolate`` can be used to tell the underlying PMD that ingress traffic
4140 must only be injected from the defined flow rules; that no default traffic
4141 is expected outside those rules and the driver is free to assign more
4142 resources to handle them. It is bound to ``rte_flow_isolate()``::
4144 flow isolate {port_id} {boolean}
4146 If successful, enabling or disabling isolated mode shows either::
4148 Ingress traffic on port [...]
4149 is now restricted to the defined flow rules
4153 Ingress traffic on port [...]
4154 is not restricted anymore to the defined flow rules
4156 Otherwise, in case of error::
4158 Caught error type [...] ([...]): [...]
4160 Mainly due to its side effects, PMDs supporting this mode may not have the
4161 ability to toggle it more than once without reinitializing affected ports
4162 first (e.g. by exiting testpmd).
4164 Enabling isolated mode::
4166 testpmd> flow isolate 0 true
4167 Ingress traffic on port 0 is now restricted to the defined flow rules
4170 Disabling isolated mode::
4172 testpmd> flow isolate 0 false
4173 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
4176 Sample QinQ flow rules
4177 ~~~~~~~~~~~~~~~~~~~~~~
4179 Before creating QinQ rule(s) the following commands should be issued to enable QinQ::
4181 testpmd> port stop 0
4182 testpmd> vlan set qinq on 0
4184 The above command sets the inner and outer TPID's to 0x8100.
4186 To change the TPID's the following commands should be used::
4188 testpmd> vlan set outer tpid 0xa100 0
4189 testpmd> vlan set inner tpid 0x9100 0
4190 testpmd> port start 0
4192 Validate and create a QinQ rule on port 0 to steer traffic to a VF queue in a VM.
4196 testpmd> flow validate 0 ingress pattern eth / vlan tci is 123 /
4197 vlan tci is 456 / end actions vf id 1 / queue index 0 / end
4198 Flow rule #0 validated
4200 testpmd> flow create 0 ingress pattern eth / vlan tci is 4 /
4201 vlan tci is 456 / end actions vf id 123 / queue index 0 / end
4202 Flow rule #0 created
4204 testpmd> flow list 0
4205 ID Group Prio Attr Rule
4206 0 0 0 i- ETH VLAN VLAN=>VF QUEUE
4208 Validate and create a QinQ rule on port 0 to steer traffic to a queue on the host.
4212 testpmd> flow validate 0 ingress pattern eth / vlan tci is 321 /
4213 vlan tci is 654 / end actions pf / queue index 0 / end
4214 Flow rule #1 validated
4216 testpmd> flow create 0 ingress pattern eth / vlan tci is 321 /
4217 vlan tci is 654 / end actions pf / queue index 1 / end
4218 Flow rule #1 created
4220 testpmd> flow list 0
4221 ID Group Prio Attr Rule
4222 0 0 0 i- ETH VLAN VLAN=>VF QUEUE
4223 1 0 0 i- ETH VLAN VLAN=>PF QUEUE

4394 Sample MPLSoUDP encapsulation rule
4395 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4397 MPLSoUDP encapsulation outer layer has default value pre-configured in testpmd
4398 source code, those can be changed by using the following commands
4400 IPv4 MPLSoUDP outer header::
4402 testpmd> set mplsoudp_encap ip-version ipv4 label 4 udp-src 5 udp-dst 10
4403 ip-src 127.0.0.1 ip-dst 128.0.0.1 eth-src 11:11:11:11:11:11

4432 Sample MPLSoUDP decapsulation rule
4433 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4435 MPLSoUDP decapsulation outer layer has default value pre-configured in testpmd
4436 source code, those can be changed by using the following commands
4438 IPv4 MPLSoUDP outer header::
4440 testpmd> set mplsoudp_decap ip-version ipv4
4441 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / mpls / end actions

4447 testpmd> flow create 0 ingress pattern eth / vlan / ipv4 / udp / mpls / end
4448 actions mplsoudp_decap / l2_encap / end
4450 IPv6 MPLSoUDP outer header::

4465 The following sections show functions to load/unload eBPF based filters.
4470 Load an eBPF program as a callback for partciular RX/TX queue::
4472 testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)
4474 The available load-flags are:
4476 * ``J``: use JIT generated native code, otherwise BPF interpreter will be used.
4478 * ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.
4484 You'll need clang v3.7 or above to build bpf program you'd like to load
4488 .. code-block:: console
4491 clang -O2 -target bpf -c t1.c
4493 Then to load (and JIT compile) t1.o at RX queue 0, port 1::
4495 .. code-block:: console
4497 testpmd> bpf-load rx 1 0 J ./dpdk.org/test/bpf/t1.o
4499 To load (not JITed) t1.o at TX queue 0, port 0::
4501 .. code-block:: console
4503 testpmd> bpf-load tx 0 0 - ./dpdk.org/test/bpf/t1.o
4508 Unload previously loaded eBPF program for partciular RX/TX queue::
4510 testpmd> bpf-unload rx|tx (portid) (queueid)
4512 For example to unload BPF filter from TX queue 0, port 0:
4514 .. code-block:: console
4516 testpmd> bpf-load tx 0 0 - ./dpdk.org/test/bpf/t1.o
