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

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

262 The available information categories are:
264 * ``rxtx``: RX/TX configuration items.
266 * ``cores``: List of forwarding cores.
268 * ``fwd``: Packet forwarding configuration.
270 * ``txpkts``: Packets to TX configuration.

292 rxonly|txonly|csum|icmpecho) (""|retry)
294 ``retry`` can be specified for forwarding engines except ``rx_only``.
296 The available information categories are:
298 * ``io``: Forwards packets "as-is" in I/O mode.
299 This is the fastest possible forwarding operation as it does not access packets data.
300 This is the default mode.
302 * ``mac``: Changes the source and the destination Ethernet addresses of packets before forwarding them.
303 Default application behaviour is to set source Ethernet address to that of the transmitting interface, and destination
304 address to a dummy value (set during init). The user may specify a target destination Ethernet address via the 'eth-peer' or
305 'eth-peer-configfile' command-line options. It is not currently possible to specify a specific source Ethernet address.
307 * ``macswap``: MAC swap forwarding mode.
308 Swaps the source and the destination Ethernet addresses of packets before forwarding them.
310 * ``flowgen``: Multi-flow generation mode.
311 Originates a number of flows (with varying destination IP addresses), and terminate receive traffic.
313 * ``rxonly``: Receives packets but doesn't transmit them.
315 * ``txonly``: Generates and transmits packets without receiving any.
317 * ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet.
319 * ``icmpecho``: Receives a burst of packets, lookup for IMCP echo requests and, if any, send back ICMP echo replies.
321 * ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX. Requires ``CONFIG_RTE_LIBRTE_IEEE1588=y``.
323 * ``tm``: Traffic Management forwarding mode
324 Demonstrates the use of ethdev traffic management APIs and softnic PMD for
325 QoS traffic management. In this mode, 5-level hierarchical QoS scheduler is
326 available as an default option that can be enabled through CLI. The user can
327 also modify the default hierarchy or specify the new hierarchy through CLI for
328 implementing QoS scheduler. Requires ``CONFIG_RTE_LIBRTE_PMD_SOFTNIC=y`` ``CONFIG_RTE_LIBRTE_SCHED=y``.

425 Configuration Functions
426 -----------------------
428 The testpmd application can be configured from the runtime as well as from the command-line.
430 This section details the available configuration functions that are available.
434 Configuration changes only become active when forwarding is started/restarted.
439 Reset forwarding to the default configuration::
446 Set the debug verbosity level::
448 testpmd> set verbose (level)
450 Currently the only available levels are 0 (silent except for error) and 1 (fully verbose).
455 Set the log level for a log type::
457 testpmd> set log global|(type) (level)
461 * ``type`` is the log name.
463 * ``level`` is the log level.
465 For example, to change the global log level::
466 testpmd> set log global (level)
468 Regexes can also be used for type. To change log level of user1, user2 and user3::
469 testpmd> set log user[1-3] (level)
474 Set the number of ports used by the application:
478 This is equivalent to the ``--nb-ports`` command-line option.
483 Set the number of cores used by the application::
485 testpmd> set nbcore (num)
487 This is equivalent to the ``--nb-cores`` command-line option.
491 The number of cores used must not be greater than number of ports used multiplied by the number of queues per port.
496 Set the forwarding cores hexadecimal mask::
498 testpmd> set coremask (mask)
500 This is equivalent to the ``--coremask`` command-line option.
504 The master lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
509 Set the forwarding ports hexadecimal mask::
511 testpmd> set portmask (mask)
513 This is equivalent to the ``--portmask`` command-line option.
518 Set number of packets per burst::
520 testpmd> set burst (num)
522 This is equivalent to the ``--burst command-line`` option.
524 When retry is enabled, the transmit delay time and number of retries can also be set::
526 testpmd> set burst tx delay (microseconds) retry (num)
531 Set the length of each segment of the TX-ONLY packets or length of packet for FLOWGEN mode::
533 testpmd> set txpkts (x[,y]*)
535 Where x[,y]* represents a CSV list of values, without white space.
540 Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes::
542 testpmd> set txsplit (off|on|rand)
546 * ``off`` disable packet copy & split for CSUM mode.
548 * ``on`` split outgoing packet into multiple segments. Size of each segment
549 and number of segments per packet is determined by ``set txpkts`` command
552 * ``rand`` same as 'on', but number of segments per each packet is a random value between 1 and total number of segments.
557 Set the list of forwarding cores::
559 testpmd> set corelist (x[,y]*)
561 For example, to change the forwarding cores:
563 .. code-block:: console
565 testpmd> set corelist 3,1
566 testpmd> show config fwd
568 io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled
569 Logical Core 3 (socket 0) forwards packets on 1 streams:
570 RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
571 Logical Core 1 (socket 0) forwards packets on 1 streams:
572 RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
576 The cores are used in the same order as specified on the command line.
581 Set the list of forwarding ports::
583 testpmd> set portlist (x[,y]*)
585 For example, to change the port forwarding:
587 .. code-block:: console
589 testpmd> set portlist 0,2,1,3
590 testpmd> show config fwd
592 io packet forwarding - ports=4 - cores=1 - streams=4
593 Logical Core 3 (socket 0) forwards packets on 4 streams:
594 RX P=0/Q=0 (socket 0) -> TX P=2/Q=0 (socket 0) peer=02:00:00:00:00:01
595 RX P=2/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
596 RX P=1/Q=0 (socket 0) -> TX P=3/Q=0 (socket 0) peer=02:00:00:00:00:03
597 RX P=3/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:02

630 Enable/disable MACsec offload::
632 testpmd> set macsec offload (port_id) on encrypt (on|off) replay-protect (on|off)
633 testpmd> set macsec offload (port_id) off
638 Configure MACsec secure connection (SC)::
640 testpmd> set macsec sc (tx|rx) (port_id) (mac) (pi)
644 The pi argument is ignored for tx.
645 Check the NIC Datasheet for hardware limits.
650 Configure MACsec secure association (SA)::
652 testpmd> set macsec sa (tx|rx) (port_id) (idx) (an) (pn) (key)
656 The IDX value must be 0 or 1.
657 Check the NIC Datasheet for hardware limits.
659 set broadcast mode (for VF)

731 TPID value must be a 16-bit number (value <= 65536).
736 Add a VLAN ID, or all identifiers, to the set of VLAN identifiers filtered by port ID::
738 testpmd> rx_vlan add (vlan_id|all) (port_id)
742 VLAN filter must be set on that port. VLAN ID < 4096.
743 Depending on the NIC used, number of vlan_ids may be limited to the maximum entries
744 in VFTA table. This is important if enabling all vlan_ids.
749 Remove a VLAN ID, or all identifiers, from the set of VLAN identifiers filtered by port ID::

770 Add a tunnel filter on a port::
772 testpmd> tunnel_filter add (port_id) (outer_mac) (inner_mac) (ip_addr) \
773 (inner_vlan) (vxlan|nvgre|ipingre) (imac-ivlan|imac-ivlan-tenid|\
774 imac-tenid|imac|omac-imac-tenid|oip|iip) (tenant_id) (queue_id)
776 The available information categories are:
778 * ``vxlan``: Set tunnel type as VXLAN.
780 * ``nvgre``: Set tunnel type as NVGRE.
782 * ``ipingre``: Set tunnel type as IP-in-GRE.
784 * ``imac-ivlan``: Set filter type as Inner MAC and VLAN.

800 testpmd> tunnel_filter add 0 68:05:CA:28:09:82 00:00:00:00:00:00 \
801 192.168.2.2 0 ipingre oip 1 1
803 Set an IP-in-GRE tunnel on port 0, and the filter type is Outer IP.
808 Remove a tunnel filter on a port::
810 testpmd> tunnel_filter rm (port_id) (outer_mac) (inner_mac) (ip_addr) \
811 (inner_vlan) (vxlan|nvgre|ipingre) (imac-ivlan|imac-ivlan-tenid|\
812 imac-tenid|imac|omac-imac-tenid|oip|iip) (tenant_id) (queue_id)
817 Add an UDP port for VXLAN packet filter on a port::
819 testpmd> rx_vxlan_port add (udp_port) (port_id)
824 Remove an UDP port for VXLAN packet filter on a port::
826 testpmd> rx_vxlan_port rm (udp_port) (port_id)
831 Set hardware insertion of VLAN IDs in packets sent on a port::
833 testpmd> tx_vlan set (port_id) vlan_id[, vlan_id_outer]
835 For example, set a single VLAN ID (5) insertion on port 0::
839 Or, set double VLAN ID (inner: 2, outer: 3) insertion on port 1::
847 Set port based hardware insertion of VLAN ID in packets sent on a port::
849 testpmd> tx_vlan set pvid (port_id) (vlan_id) (on|off)
854 Disable hardware insertion of a VLAN header in packets sent on a port::
856 testpmd> tx_vlan reset (port_id)
861 Select hardware or software calculation of the checksum when
862 transmitting a packet using the ``csum`` forwarding engine::
864 testpmd> csum set (ip|udp|tcp|sctp|outer-ip) (hw|sw) (port_id)
868 * ``ip|udp|tcp|sctp`` always relate to the inner layer.
870 * ``outer-ip`` relates to the outer IP layer (only for IPv4) in the case where the packet is recognized
871 as a tunnel packet by the forwarding engine (vxlan, gre and ipip are
872 supported). See also the ``csum parse-tunnel`` command.
876 Check the NIC Datasheet for hardware limits.
881 Set RSS queue region span on a port::
883 testpmd> set port (port_id) queue-region region_id (value) \
884 queue_start_index (value) queue_num (value)
886 Set flowtype mapping on a RSS queue region on a port::
888 testpmd> set port (port_id) queue-region region_id (value) flowtype (value)
892 * For the flowtype(pctype) of packet,the specific index for each type has
893 been defined in file i40e_type.h as enum i40e_filter_pctype.
895 Set user priority mapping on a RSS queue region on a port::
897 testpmd> set port (port_id) queue-region UP (value) region_id (value)
899 Flush all queue region related configuration on a port::
901 testpmd> set port (port_id) queue-region flush (on|off)
905 * "on"is just an enable function which server for other configuration,
906 it is for all configuration about queue region from up layer,
907 at first will only keep in DPDK softwarestored in driver,
908 only after "flush on", it commit all configuration to HW.
909 "off" is just clean all configuration about queue region just now,
910 and restore all to DPDK i40e driver default config when start up.
912 Show all queue region related configuration info on a port::
914 testpmd> show port (port_id) queue-region
918 Queue region only support on PF by now, so these command is
919 only for configuration of queue region on PF port.
924 Define how tunneled packets should be handled by the csum forward
927 testpmd> csum parse-tunnel (on|off) (tx_port_id)
929 If enabled, the csum forward engine will try to recognize supported
930 tunnel headers (vxlan, gre, ipip).
932 If disabled, treat tunnel packets as non-tunneled packets (a inner
933 header is handled as a packet payload).
937 The port argument is the TX port like in the ``csum set`` command.
941 Consider a packet in packet like the following::
943 eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in
945 * If parse-tunnel is enabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
946 command relate to the inner headers (here ``ipv4_in`` and ``tcp_in``), and the

964 testpmd> tso set (segsize) (port_id)
968 Check the NIC datasheet for hardware limits.
973 Display the status of TCP Segmentation Offload::
975 testpmd> tso show (port_id)
980 Enable or disable GRO in ``csum`` forwarding engine::
982 testpmd> set port <port_id> gro on|off
984 If enabled, the csum forwarding engine will perform GRO on the TCP/IPv4
985 packets received from the given port.
987 If disabled, packets received from the given port won't be performed
988 GRO. By default, GRO is disabled for all ports.
992 When enable GRO for a port, TCP/IPv4 packets received from the port
993 will be performed GRO. After GRO, all merged packets have bad
994 checksums, since the GRO library doesn't re-calculate checksums for
995 the merged packets. Therefore, if users want the merged packets to
996 have correct checksums, please select HW IP checksum calculation and
997 HW TCP checksum calculation for the port which the merged packets are
1003 Display GRO configuration for a given port::
1005 testpmd> show port <port_id> gro
1010 Set the cycle to flush the GROed packets from reassembly tables::
1012 testpmd> set gro flush <cycles>
1014 When enable GRO, the csum forwarding engine performs GRO on received
1015 packets, and the GROed packets are stored in reassembly tables. Users
1016 can use this command to determine when the GROed packets are flushed
1017 from the reassembly tables.
1019 The ``cycles`` is measured in GRO operation times. The csum forwarding
1020 engine flushes the GROed packets from the tables every ``cycles`` GRO
1023 By default, the value of ``cycles`` is 1, which means flush GROed packets
1024 from the reassembly tables as soon as one GRO operation finishes. The value
1025 of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``.
1027 Please note that the large value of ``cycles`` may cause the poor TCP/IP
1028 stack performance. Because the GROed packets are delayed to arrive the
1029 stack, thus causing more duplicated ACKs and TCP retransmissions.
1034 Toggle per-port GSO support in ``csum`` forwarding engine::
1036 testpmd> set port <port_id> gso on|off
1038 If enabled, the csum forwarding engine will perform GSO on supported IPv4
1039 packets, transmitted on the given port.
1041 If disabled, packets transmitted on the given port will not undergo GSO.
1042 By default, GSO is disabled for all ports.
1046 When GSO is enabled on a port, supported IPv4 packets transmitted on that
1047 port undergo GSO. Afterwards, the segmented packets are represented by
1048 multi-segment mbufs; however, the csum forwarding engine doesn't calculation
1049 of checksums for GSO'd segments in SW. As a result, if users want correct
1050 checksums in GSO segments, they should enable HW checksum calculation for
1053 For example, HW checksum calculation for VxLAN GSO'd packets may be enabled
1054 by setting the following options in the csum forwarding engine:
1056 testpmd> csum set outer_ip hw <port_id>
1058 testpmd> csum set ip hw <port_id>
1060 testpmd> csum set tcp hw <port_id>
1062 UDP GSO is the same as IP fragmentation, which treats the UDP header
1063 as the payload and does not modify it during segmentation. That is,
1064 after UDP GSO, only the first output fragment has the original UDP
1065 header. Therefore, users need to enable HW IP checksum calculation
1066 and SW UDP checksum calculation for GSO-enabled ports, if they want
1067 correct checksums for UDP/IPv4 packets.
1072 Set the maximum GSO segment size (measured in bytes), which includes the
1073 packet header and the packet payload for GSO-enabled ports (global)::
1075 testpmd> set gso segsz <length>

1548 The following sections show functions for configuring ports.
1552 Port configuration changes only become active when forwarding is started/restarted.
1557 Attach a port specified by pci address or virtual device args::
1559 testpmd> port attach (identifier)
1561 To attach a new pci device, the device should be recognized by kernel first.
1562 Then it should be moved under DPDK management.
1563 Finally the port can be attached to testpmd.
1565 For example, to move a pci device using ixgbe under DPDK management:
1567 .. code-block:: console
1569 # Check the status of the available devices.
1570 ./usertools/dpdk-devbind.py --status
1572 Network devices using DPDK-compatible driver

1581 # Bind the device to igb_uio.
1582 sudo ./usertools/dpdk-devbind.py -b igb_uio 0000:0a:00.0
1585 # Recheck the status of the devices.
1586 ./usertools/dpdk-devbind.py --status

1588 ============================================
1589 0000:0a:00.0 '82599ES 10-Gigabit' drv=igb_uio unused=
1591 To attach a port created by virtual device, above steps are not needed.
1593 For example, to attach a port whose pci address is 0000:0a:00.0.
1595 .. code-block:: console
1597 testpmd> port attach 0000:0a:00.0
1598 Attaching a new port...
1599 EAL: PCI device 0000:0a:00.0 on NUMA socket -1
1600 EAL: probe driver: 8086:10fb rte_ixgbe_pmd
1601 EAL: PCI memory mapped at 0x7f83bfa00000
1602 EAL: PCI memory mapped at 0x7f83bfa80000
1603 PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
1604 PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
1605 Port 0 is attached. Now total ports is 1
1608 For example, to attach a port created by pcap PMD.
1610 .. code-block:: console
1612 testpmd> port attach net_pcap0
1613 Attaching a new port...
1614 PMD: Initializing pmd_pcap for net_pcap0
1615 PMD: Creating pcap-backed ethdev on numa socket 0
1616 Port 0 is attached. Now total ports is 1
1619 In this case, identifier is ``net_pcap0``.
1620 This identifier format is the same as ``--vdev`` format of DPDK applications.
1622 For example, to re-attach a bonded port which has been previously detached,
1623 the mode and slave parameters must be given.
1625 .. code-block:: console
1627 testpmd> port attach net_bond_0,mode=0,slave=1
1628 Attaching a new port...
1629 EAL: Initializing pmd_bond for net_bond_0
1630 EAL: Create bonded device net_bond_0 on port 0 in mode 0 on socket 0.
1631 Port 0 is attached. Now total ports is 1
1638 Detach a specific port::
1640 testpmd> port detach (port_id)
1642 Before detaching a port, the port should be stopped and closed.
1644 For example, to detach a pci device port 0.
1646 .. code-block:: console
1648 testpmd> port stop 0
1651 testpmd> port close 0
1655 testpmd> port detach 0
1657 EAL: PCI device 0000:0a:00.0 on NUMA socket -1
1658 EAL: remove driver: 8086:10fb rte_ixgbe_pmd
1659 EAL: PCI memory unmapped at 0x7f83bfa00000
1660 EAL: PCI memory unmapped at 0x7f83bfa80000
1664 For example, to detach a virtual device port 0.
1666 .. code-block:: console
1668 testpmd> port stop 0
1671 testpmd> port close 0
1675 testpmd> port detach 0
1677 PMD: Closing pcap ethdev on numa socket 0
1678 Port 'net_pcap0' is detached. Now total ports is 0
1681 To remove a pci device completely from the system, first detach the port from testpmd.
1682 Then the device should be moved under kernel management.
1683 Finally the device can be removed using kernel pci hotplug functionality.
1685 For example, to move a pci device under kernel management:
1687 .. code-block:: console
1689 sudo ./usertools/dpdk-devbind.py -b ixgbe 0000:0a:00.0
1691 ./usertools/dpdk-devbind.py --status

1701 To remove a port created by a virtual device, above steps are not needed.
1706 Start all ports or a specific port::
1708 testpmd> port start (port_id|all)
1713 Stop all ports or a specific port::
1715 testpmd> port stop (port_id|all)
1720 Close all ports or a specific port::
1722 testpmd> port close (port_id|all)
1724 port config - queue ring size
1725 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1727 Configure a rx/tx queue ring size::
1729 testpmd> port (port_id) (rxq|txq) (queue_id) ring_size (value)
1731 Only take effect after command that (re-)start the port or command that setup specific queue.
1733 port start/stop queue

2814 flow_director_filter
2815 ~~~~~~~~~~~~~~~~~~~~
2817 The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.
2819 Four types of filtering are supported which are referred to as Perfect Match, Signature, Perfect-mac-vlan and
2820 Perfect-tunnel filters, the match mode is set by the ``--pkt-filter-mode`` command-line parameter:
2822 * Perfect match filters.
2823 The hardware checks a match between the masked fields of the received packets and the programmed filters.
2824 The masked fields are for IP flow.
2826 * Signature filters.
2827 The hardware checks a match between a hash-based signature of the masked fields of the received packet.
2829 * Perfect-mac-vlan match filters.
2830 The hardware checks a match between the masked fields of the received packets and the programmed filters.
2831 The masked fields are for MAC VLAN flow.
2833 * Perfect-tunnel match filters.
2834 The hardware checks a match between the masked fields of the received packets and the programmed filters.
2835 The masked fields are for tunnel flow.
2837 * Perfect-raw-flow-type match filters.
2838 The hardware checks a match between the masked fields of the received packets and pre-loaded raw (template) packet.
2839 The masked fields are specified by input sets.
2841 The Flow Director filters can match the different fields for different type of packet: flow type, specific input set
2842 per flow type and the flexible payload.
2844 The Flow Director can also mask out parts of all of these fields so that filters
2845 are only applied to certain fields or parts of the fields.
2847 Note that for raw flow type mode the source and destination fields in the
2848 raw packet buffer need to be presented in a reversed order with respect
2849 to the expected received packets.
2850 For example: IP source and destination addresses or TCP/UDP/SCTP
2851 source and destination ports
2853 Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information.

3077 Control of the generic flow API (*rte_flow*) is fully exposed through the
3078 ``flow`` command (validation, creation, destruction, queries and operation
3081 Considering *rte_flow* overlaps with all `Filter Functions`_, using both
3082 features simultaneously may cause undefined side-effects and is therefore
3088 Because the ``flow`` command uses dynamic tokens to handle the large number
3089 of possible flow rules combinations, its behavior differs slightly from
3090 other commands, in particular:
3092 - Pressing *?* or the *<tab>* key displays contextual help for the current
3093 token, not that of the entire command.
3095 - Optional and repeated parameters are supported (provided they are listed
3096 in the contextual help).
3098 The first parameter stands for the operation mode. Possible operations and
3099 their general syntax are described below. They are covered in detail in the
3102 - Check whether a flow rule can be created::
3104 flow validate {port_id}
3105 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3106 pattern {item} [/ {item} [...]] / end
3107 actions {action} [/ {action} [...]] / end
3109 - Create a flow rule::
3111 flow create {port_id}
3112 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3113 pattern {item} [/ {item} [...]] / end
3114 actions {action} [/ {action} [...]] / end
3116 - Destroy specific flow rules::
3118 flow destroy {port_id} rule {rule_id} [...]
3120 - Destroy all flow rules::
3122 flow flush {port_id}
3124 - Query an existing flow rule::
3126 flow query {port_id} {rule_id} {action}
3128 - List existing flow rules sorted by priority, filtered by group
3131 flow list {port_id} [group {group_id}] [...]
3133 - Restrict ingress traffic to the defined flow rules::
3135 flow isolate {port_id} {boolean}
3137 Validating flow rules
3138 ~~~~~~~~~~~~~~~~~~~~~
3140 ``flow validate`` reports whether a flow rule would be accepted by the
3141 underlying device in its current state but stops short of creating it. It is
3142 bound to ``rte_flow_validate()``::
3144 flow validate {port_id}
3145 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3146 pattern {item} [/ {item} [...]] / end
3147 actions {action} [/ {action} [...]] / end
3149 If successful, it will show::
3153 Otherwise it will show an error message of the form::
3155 Caught error type [...] ([...]): [...]
3157 This command uses the same parameters as ``flow create``, their format is
3158 described in `Creating flow rules`_.
3160 Check whether redirecting any Ethernet packet received on port 0 to RX queue
3161 index 6 is supported::
3163 testpmd> flow validate 0 ingress pattern eth / end
3164 actions queue index 6 / end
3168 Port 0 does not support TCPv6 rules::
3170 testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
3172 Caught error type 9 (specific pattern item): Invalid argument
3178 ``flow create`` validates and creates the specified flow rule. It is bound
3179 to ``rte_flow_create()``::
3181 flow create {port_id}
3182 [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3183 pattern {item} [/ {item} [...]] / end
3184 actions {action} [/ {action} [...]] / end
3186 If successful, it will return a flow rule ID usable with other commands::
3188 Flow rule #[...] created
3190 Otherwise it will show an error message of the form::
3192 Caught error type [...] ([...]): [...]
3194 Parameters describe in the following order:
3196 - Attributes (*group*, *priority*, *ingress*, *egress*, *transfer* tokens).
3197 - A matching pattern, starting with the *pattern* token and terminated by an
3199 - Actions, starting with the *actions* token and terminated by an *end*
3202 These translate directly to *rte_flow* objects provided as-is to the
3203 underlying functions.
3205 The shortest valid definition only comprises mandatory tokens::
3207 testpmd> flow create 0 pattern end actions end
3209 Note that PMDs may refuse rules that essentially do nothing such as this
3212 **All unspecified object values are automatically initialized to 0.**
3217 These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
3218 specified before the ``pattern`` token.
3220 - ``group {group id}``: priority group.
3221 - ``priority {level}``: priority level within group.
3222 - ``ingress``: rule applies to ingress traffic.
3223 - ``egress``: rule applies to egress traffic.
3224 - ``transfer``: apply rule directly to endpoints found in pattern.
3226 Each instance of an attribute specified several times overrides the previous
3227 value as shown below (group 4 is used)::
3229 testpmd> flow create 0 group 42 group 24 group 4 [...]
3231 Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
3233 While not specifying a direction is an error, some rules may allow both
3236 Most rules affect RX therefore contain the ``ingress`` token::
3238 testpmd> flow create 0 ingress pattern [...]
3243 A matching pattern starts after the ``pattern`` token. It is made of pattern
3244 items and is terminated by a mandatory ``end`` item.
3246 Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
3247 rte_flow_item_type``).
3249 The ``/`` token is used as a separator between pattern items as shown
3252 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
3254 Note that protocol items like these must be stacked from lowest to highest
3255 layer to make sense. For instance, the following rule is either invalid or
3256 unlikely to match any packet::
3258 testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
3260 More information on these restrictions can be found in the *rte_flow*
3263 Several items support additional specification structures, for example
3264 ``ipv4`` allows specifying source and destination addresses as follows::
3266 testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
3267 dst is 10.2.0.0 / end [...]
3269 This rule matches all IPv4 traffic with the specified properties.
3271 In this example, ``src`` and ``dst`` are field names of the underlying
3272 ``struct rte_flow_item_ipv4`` object. All item properties can be specified
3273 in a similar fashion.
3275 The ``is`` token means that the subsequent value must be matched exactly,
3276 and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
3277 accordingly. Possible assignment tokens are:
3279 - ``is``: match value perfectly (with full bit-mask).
3280 - ``spec``: match value according to configured bit-mask.
3281 - ``last``: specify upper bound to establish a range.
3282 - ``mask``: specify bit-mask with relevant bits set to one.
3283 - ``prefix``: generate bit-mask from a prefix length.
3285 These yield identical results::
3287 ipv4 src is 10.1.1.1
3291 ipv4 src spec 10.1.1.1 src mask 255.255.255.255
3295 ipv4 src spec 10.1.1.1 src prefix 32
3299 ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
3303 ipv4 src is 10.1.1.1 src last 0 # 0 disables range
3305 Inclusive ranges can be defined with ``last``::
3307 ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
3309 Note that ``mask`` affects both ``spec`` and ``last``::
3311 ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0
3312 # matches 10.1.0.0 to 10.2.255.255
3314 Properties can be modified multiple times::
3316 ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
3320 ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16

3494 A list of actions starts after the ``actions`` token in the same fashion as
3495 `Matching pattern`_; actions are separated by ``/`` tokens and the list is
3496 terminated by a mandatory ``end`` action.
3498 Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
3499 rte_flow_action_type``).
3501 Dropping all incoming UDPv4 packets can be expressed as follows::
3503 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3506 Several actions have configurable properties which must be specified when
3507 there is no valid default value. For example, ``queue`` requires a target
3510 This rule redirects incoming UDPv4 traffic to queue index 6::
3512 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3513 actions queue index 6 / end
3515 While this one could be rejected by PMDs (unspecified queue index)::
3517 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3520 As defined by *rte_flow*, the list is not ordered, all actions of a given
3521 rule are performed simultaneously. These are equivalent::
3523 queue index 6 / void / mark id 42 / end
3527 void / mark id 42 / queue index 6 / end
3529 All actions in a list should have different types, otherwise only the last
3530 action of a given type is taken into account::
3532 queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
3536 drop / drop / drop / end # drop is performed only once
3540 mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
3542 Considering they are performed simultaneously, opposite and overlapping
3543 actions can sometimes be combined when the end result is unambiguous::
3545 drop / queue index 6 / end # drop has no effect
3549 queue index 6 / rss queues 6 7 8 / end # queue has no effect
3553 drop / passthru / end # drop has no effect
3555 Note that PMDs may still refuse such combinations.

3594 tokens are the same as `set_hash_input_set`_, except that an empty list
3595 does not disable RSS but instead requests unspecified "best-effort"
3598 - ``key {string}``: RSS hash key, overrides ``key_len``.
3600 - ``key_len {unsigned}``: RSS hash key length in bytes, can be used in
3601 conjunction with ``key`` to pad or truncate it.

3660 Destroying flow rules
3661 ~~~~~~~~~~~~~~~~~~~~~
3663 ``flow destroy`` destroys one or more rules from their rule ID (as returned
3664 by ``flow create``), this command calls ``rte_flow_destroy()`` as many
3665 times as necessary::
3667 flow destroy {port_id} rule {rule_id} [...]
3669 If successful, it will show::
3671 Flow rule #[...] destroyed
3673 It does not report anything for rule IDs that do not exist. The usual error
3674 message is shown when a rule cannot be destroyed::
3676 Caught error type [...] ([...]): [...]
3678 ``flow flush`` destroys all rules on a device and does not take extra
3679 arguments. It is bound to ``rte_flow_flush()``::
3681 flow flush {port_id}
3683 Any errors are reported as above.
3685 Creating several rules and destroying them::
3687 testpmd> flow create 0 ingress pattern eth / ipv6 / end
3688 actions queue index 2 / end
3689 Flow rule #0 created
3690 testpmd> flow create 0 ingress pattern eth / ipv4 / end
3691 actions queue index 3 / end
3692 Flow rule #1 created
3693 testpmd> flow destroy 0 rule 0 rule 1
3694 Flow rule #1 destroyed
3695 Flow rule #0 destroyed
3698 The same result can be achieved using ``flow flush``::
3700 testpmd> flow create 0 ingress pattern eth / ipv6 / end
3701 actions queue index 2 / end
3702 Flow rule #0 created
3703 testpmd> flow create 0 ingress pattern eth / ipv4 / end
3704 actions queue index 3 / end
3705 Flow rule #1 created
3706 testpmd> flow flush 0
3709 Non-existent rule IDs are ignored::
3711 testpmd> flow create 0 ingress pattern eth / ipv6 / end
3712 actions queue index 2 / end
3713 Flow rule #0 created
3714 testpmd> flow create 0 ingress pattern eth / ipv4 / end
3715 actions queue index 3 / end
3716 Flow rule #1 created
3717 testpmd> flow destroy 0 rule 42 rule 10 rule 2
3719 testpmd> flow destroy 0 rule 0
3720 Flow rule #0 destroyed
3726 ``flow query`` queries a specific action of a flow rule having that
3727 ability. Such actions collect information that can be reported using this
3728 command. It is bound to ``rte_flow_query()``::
3730 flow query {port_id} {rule_id} {action}
3732 If successful, it will display either the retrieved data for known actions
3733 or the following message::
3735 Cannot display result for action type [...] ([...])
3737 Otherwise, it will complain either that the rule does not exist or that some
3740 Flow rule #[...] not found
3744 Caught error type [...] ([...]): [...]
3746 Currently only the ``count`` action is supported. This action reports the
3747 number of packets that hit the flow rule and the total number of bytes. Its
3748 output has the following format::
3751 hits_set: [...] # whether "hits" contains a valid value
3752 bytes_set: [...] # whether "bytes" contains a valid value
3753 hits: [...] # number of packets
3754 bytes: [...] # number of bytes
3756 Querying counters for TCPv6 packets redirected to queue 6::
3758 testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
3759 actions queue index 6 / count / end
3760 Flow rule #4 created
3761 testpmd> flow query 0 4 count
3772 ``flow list`` lists existing flow rules sorted by priority and optionally
3773 filtered by group identifiers::
3775 flow list {port_id} [group {group_id}] [...]
3777 This command only fails with the following message if the device does not
3782 Output consists of a header line followed by a short description of each
3783 flow rule, one per line. There is no output at all when no flow rules are
3784 configured on the device::
3786 ID Group Prio Attr Rule
3787 [...] [...] [...] [...] [...]
3789 ``Attr`` column flags:
3791 - ``i`` for ``ingress``.
3792 - ``e`` for ``egress``.
3794 Creating several flow rules and listing them::
3796 testpmd> flow create 0 ingress pattern eth / ipv4 / end
3797 actions queue index 6 / end
3798 Flow rule #0 created
3799 testpmd> flow create 0 ingress pattern eth / ipv6 / end
3800 actions queue index 2 / end
3801 Flow rule #1 created
3802 testpmd> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
3803 actions rss queues 6 7 8 end / end
3804 Flow rule #2 created
3805 testpmd> flow list 0
3806 ID Group Prio Attr Rule
3807 0 0 0 i- ETH IPV4 => QUEUE
3808 1 0 0 i- ETH IPV6 => QUEUE
3809 2 0 5 i- ETH IPV4 UDP => RSS
3812 Rules are sorted by priority (i.e. group ID first, then priority level)::
3814 testpmd> flow list 1

3836 Toggling isolated mode
3837 ~~~~~~~~~~~~~~~~~~~~~~
3839 ``flow isolate`` can be used to tell the underlying PMD that ingress traffic
3840 must only be injected from the defined flow rules; that no default traffic
3841 is expected outside those rules and the driver is free to assign more
3842 resources to handle them. It is bound to ``rte_flow_isolate()``::
3844 flow isolate {port_id} {boolean}
3846 If successful, enabling or disabling isolated mode shows either::
3848 Ingress traffic on port [...]
3849 is now restricted to the defined flow rules
3853 Ingress traffic on port [...]
3854 is not restricted anymore to the defined flow rules
3856 Otherwise, in case of error::
3858 Caught error type [...] ([...]): [...]
3860 Mainly due to its side effects, PMDs supporting this mode may not have the
3861 ability to toggle it more than once without reinitializing affected ports
3862 first (e.g. by exiting testpmd).
3864 Enabling isolated mode::
3866 testpmd> flow isolate 0 true
3867 Ingress traffic on port 0 is now restricted to the defined flow rules
3870 Disabling isolated mode::
3872 testpmd> flow isolate 0 false
3873 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
3876 Sample QinQ flow rules
3877 ~~~~~~~~~~~~~~~~~~~~~~
3879 Before creating QinQ rule(s) the following commands should be issued to enable QinQ::
3881 testpmd> port stop 0
3882 testpmd> vlan set qinq on 0
3884 The above command sets the inner and outer TPID's to 0x8100.
3886 To change the TPID's the following commands should be used::
3888 testpmd> vlan set outer tpid 0xa100 0
3889 testpmd> vlan set inner tpid 0x9100 0
3890 testpmd> port start 0
3892 Validate and create a QinQ rule on port 0 to steer traffic to a VF queue in a VM.
3896 testpmd> flow validate 0 ingress pattern eth / vlan tci is 123 /
3897 vlan tci is 456 / end actions vf id 1 / queue index 0 / end
3898 Flow rule #0 validated
3900 testpmd> flow create 0 ingress pattern eth / vlan tci is 4 /
3901 vlan tci is 456 / end actions vf id 123 / queue index 0 / end
3902 Flow rule #0 created
3904 testpmd> flow list 0
3905 ID Group Prio Attr Rule

3914 Flow rule #1 validated
3916 testpmd> flow create 0 ingress pattern eth / vlan tci is 321 /

3928 The following sections show functions to load/unload eBPF based filters.
3933 Load an eBPF program as a callback for partciular RX/TX queue::
3935 testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)
3937 The available load-flags are:
3939 * ``J``: use JIT generated native code, otherwise BPF interpreter will be used.
3941 * ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.
3947 You'll need clang v3.7 or above to build bpf program you'd like to load
3951 .. code-block:: console
3954 clang -O2 -target bpf -c t1.c
3956 Then to load (and JIT compile) t1.o at RX queue 0, port 1::
3958 .. code-block:: console
3960 testpmd> bpf-load rx 1 0 J ./dpdk.org/test/bpf/t1.o
3962 To load (not JITed) t1.o at TX queue 0, port 0::
3964 .. code-block:: console
3966 testpmd> bpf-load tx 0 0 - ./dpdk.org/test/bpf/t1.o
3971 Unload previously loaded eBPF program for partciular RX/TX queue::
3973 testpmd> bpf-unload rx|tx (portid) (queueid)
3975 For example to unload BPF filter from TX queue 0, port 0:
3977 .. code-block:: console
3979 testpmd> bpf-load tx 0 0 - ./dpdk.org/test/bpf/t1.o
