6Testpmd Runtime Functions
7=========================
8
9Where the testpmd application is started in interactive mode, (``-i|--interactive``),
10it displays a prompt that can be used to start and stop forwarding,
11configure the application, display statistics (including the extended NIC
12statistics aka xstats) , set the Flow Director and other tasks::
13
14   testpmd>
15
16The testpmd prompt has some, limited, readline support.
17Common bash command-line functions such as ``Ctrl+a`` and ``Ctrl+e`` to go to the start and end of the prompt line are supported
18as well as access to the command history via the up-arrow.
19
20There is also support for tab completion.
21If you type a partial command and hit ``<TAB>`` you get a list of the available completions:
22
23.. code-block:: console
24
25   testpmd> show port <TAB>
26
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
31       ...
32
33
34.. note::
35
36   Some examples in this document are too long to fit on one line are are shown wrapped at `"\\"` for display purposes::
37
38      testpmd> set flow_ctrl rx (on|off) tx (on|off) (high_water) (low_water) \
39               (pause_time) (send_xon) (port_id)
40
41In the real ``testpmd>`` prompt these commands should be on a single line.
42
43Help Functions
44--------------
45
46The testpmd has on-line help for the functions that are available at runtime.
47These are divided into sections and can be accessed using help, help section or help all:
48
49.. code-block:: console
50
51   testpmd> help
52
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.
60
61
62Command File Functions
63----------------------
64
65To facilitate loading large number of commands or to avoid cutting and pasting where not
66practical or possible testpmd supports alternative methods for executing commands.
67
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.
71
72.. code-block:: console
73
74   ./testpmd -n4 -r2 ... -- -i --cmdline-file=/home/ubuntu/flow-create-commands.txt

94
95* At run-time additional commands can be loaded in bulk by invoking the ``load FILENAME``
96  command.
97
98.. code-block:: console
99
100   testpmd> load /home/ubuntu/flow-create-commands.txt
101   Flow rule #0 created

108   testpmd>
109
110
111In all cases output from any included command will be displayed as standard output.
112Execution will continue until the end of the file is reached regardless of
113whether any errors occur.  The end user must examine the output to determine if
114any failures occurred.

248~~~~~~~~~~~~~~
249
250Display information for a given port's RX/TX queue::
251
252   testpmd> show (rxq|txq) info (port_id) (queue_id)
253
254show config
255~~~~~~~~~~~
256
257Displays the configuration of the application.
258The configuration comes from the command-line, the runtime or the application defaults::
259
260   testpmd> show config (rxtx|cores|fwd|txpkts)
261
262The available information categories are:
263
264* ``rxtx``: RX/TX configuration items.
265
266* ``cores``: List of forwarding cores.
267
268* ``fwd``: Packet forwarding configuration.

271
272For example:
273
274.. code-block:: console
275
276   testpmd> show config rxtx
277
278   io packet forwarding - CRC stripping disabled - packets/burst=16
279   nb forwarding cores=2 - nb forwarding ports=1
280   RX queues=1 - RX desc=128 - RX free threshold=0
281   RX threshold registers: pthresh=8 hthresh=8 wthresh=4
282   TX queues=1 - TX desc=512 - TX free threshold=0
283   TX threshold registers: pthresh=36 hthresh=0 wthresh=0
284   TX RS bit threshold=0 - TXQ flags=0x0
285
286set fwd
287~~~~~~~
288
289Set the packet forwarding mode::
290
291   testpmd> set fwd (io|mac|macswap|flowgen| \
292                     rxonly|txonly|csum|icmpecho) (""|retry)
293
294``retry`` can be specified for forwarding engines except ``rx_only``.
295
296The available information categories are:
297
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.
301
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.
306
307* ``macswap``: MAC swap forwarding mode.
308  Swaps the source and the destination Ethernet addresses of packets before forwarding them.
309
310* ``flowgen``: Multi-flow generation mode.
311  Originates a number of flows (with varying destination IP addresses), and terminate receive traffic.
312
313* ``rxonly``: Receives packets but doesn't transmit them.
314
315* ``txonly``: Generates and transmits packets without receiving any.
316
317* ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet.
318
319* ``icmpecho``: Receives a burst of packets, lookup for IMCP echo requests and, if any, send back ICMP echo replies.
320
321* ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX. Requires ``CONFIG_RTE_LIBRTE_IEEE1588=y``.
322
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``.
329
330Example::
331
332   testpmd> set fwd rxonly
333
334   Set rxonly packet forwarding mode
335
336

350~~~~~~~~
351
352Display a TX descriptor for a port TX queue::
353
354   testpmd> read txd (port_id) (queue_id) (txd_id)
355
356For example::
357
358   testpmd> read txd 0 0 4
359        0x00000001 - 0x24C3C440 / 0x000F0000 - 0x2330003C

397Configuration Functions
398-----------------------
399
400The testpmd application can be configured from the runtime as well as from the command-line.
401
402This section details the available configuration functions that are available.
403
404.. note::
405
406   Configuration changes only become active when forwarding is started/restarted.
407
408set default
409~~~~~~~~~~~
410
411Reset forwarding to the default configuration::
412
413   testpmd> set default
414
415set verbose
416~~~~~~~~~~~
417
418Set the debug verbosity level::
419
420   testpmd> set verbose (level)
421
422Currently the only available levels are 0 (silent except for error) and 1 (fully verbose).
423
424set log
425~~~~~~~
426
427Set the log level for a log type::
428
429	testpmd> set log global|(type) (level)
430
431Where:
432
433* ``type`` is the log name.
434
435* ``level`` is the log level.
436
437For example, to change the global log level::
438	testpmd> set log global (level)
439
440Regexes can also be used for type. To change log level of user1, user2 and user3::
441	testpmd> set log user[1-3] (level)
442
443set nbport
444~~~~~~~~~~
445
446Set the number of ports used by the application:
447
448set nbport (num)
449
450This is equivalent to the ``--nb-ports`` command-line option.
451
452set nbcore
453~~~~~~~~~~
454
455Set the number of cores used by the application::
456
457   testpmd> set nbcore (num)
458
459This is equivalent to the ``--nb-cores`` command-line option.
460
461.. note::
462
463   The number of cores used must not be greater than number of ports used multiplied by the number of queues per port.
464
465set coremask
466~~~~~~~~~~~~
467
468Set the forwarding cores hexadecimal mask::
469
470   testpmd> set coremask (mask)
471
472This is equivalent to the ``--coremask`` command-line option.
473
474.. note::
475
476   The master lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
477
478set portmask
479~~~~~~~~~~~~
480
481Set the forwarding ports hexadecimal mask::
482
483   testpmd> set portmask (mask)

485This is equivalent to the ``--portmask`` command-line option.
486
487set burst
488~~~~~~~~~
489
490Set number of packets per burst::
491
492   testpmd> set burst (num)
493
494This is equivalent to the ``--burst command-line`` option.
495
496When retry is enabled, the transmit delay time and number of retries can also be set::
497
498   testpmd> set burst tx delay (microseconds) retry (num)
499
500set txpkts
501~~~~~~~~~~
502
503Set the length of each segment of the TX-ONLY packets or length of packet for FLOWGEN mode::
504
505   testpmd> set txpkts (x[,y]*)
506
507Where x[,y]* represents a CSV list of values, without white space.
508
509set txsplit
510~~~~~~~~~~~
511
512Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes::
513
514   testpmd> set txsplit (off|on|rand)
515
516Where:
517
518* ``off`` disable packet copy & split for CSUM mode.
519
520* ``on`` split outgoing packet into multiple segments. Size of each segment
521  and number of segments per packet is determined by ``set txpkts`` command
522  (see above).
523
524* ``rand`` same as 'on', but number of segments per each packet is a random value between 1 and total number of segments.
525
526set corelist
527~~~~~~~~~~~~
528
529Set the list of forwarding cores::
530

841
842* ``outer-ip`` relates to the outer IP layer (only for IPv4) in the case where the packet is recognized
843  as a tunnel packet by the forwarding engine (vxlan, gre and ipip are
844  supported). See also the ``csum parse-tunnel`` command.
845
846.. note::
847
848   Check the NIC Datasheet for hardware limits.
849
850RSS queue region
851~~~~~~~~~~~~~~~~
852
853Set RSS queue region span on a port::
854
855   testpmd> set port (port_id) queue-region region_id (value) \
856		queue_start_index (value) queue_num (value)
857
858Set flowtype mapping on a RSS queue region on a port::
859
860   testpmd> set port (port_id) queue-region region_id (value) flowtype (value)
861
862where:
863
864* For the flowtype(pctype) of packet,the specific index for each type has

872
873   testpmd> set port (port_id) queue-region flush (on|off)
874
875where:
876
877* "on"is just an enable function which server for other configuration,
878  it is for all configuration about queue region from up layer,
879  at first will only keep in DPDK softwarestored in driver,
880  only after "flush on", it commit all configuration to HW.
881  "off" is just clean all configuration about queue region just now,
882  and restore all to DPDK i40e driver default config when start up.
883
884Show all queue region related configuration info on a port::
885
886   testpmd> show port (port_id) queue-region
887
888.. note::
889
890  Queue region only support on PF by now, so these command is
891  only for configuration of queue region on PF port.
892
893csum parse-tunnel
894~~~~~~~~~~~~~~~~~
895
896Define how tunneled packets should be handled by the csum forward
897engine::
898
899   testpmd> csum parse-tunnel (on|off) (tx_port_id)
900
901If enabled, the csum forward engine will try to recognize supported
902tunnel headers (vxlan, gre, ipip).
903
904If disabled, treat tunnel packets as non-tunneled packets (a inner
905header is handled as a packet payload).
906
907.. note::
908
909   The port argument is the TX port like in the ``csum set`` command.
910
911Example:
912
913Consider a packet in packet like the following::
914
915   eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in
916
917* If parse-tunnel is enabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
918  command relate to the inner headers (here ``ipv4_in`` and ``tcp_in``), and the
919  ``outer-ip parameter`` relates to the outer headers (here ``ipv4_out``).
920
921* If parse-tunnel is disabled, the ``ip|udp|tcp|sctp`` parameters of ``csum  set``
922   command relate to the outer headers, here ``ipv4_out`` and ``udp_out``.
923
924csum show
925~~~~~~~~~
926
927Display tx checksum offload configuration::
928
929   testpmd> csum show (port_id)
930
931tso set
932~~~~~~~
933
934Enable TCP Segmentation Offload (TSO) in the ``csum`` forwarding engine::
935
936   testpmd> tso set (segsize) (port_id)
937
938.. note::
939
940   Check the NIC datasheet for hardware limits.
941
942tso show
943~~~~~~~~
944
945Display the status of TCP Segmentation Offload::
946
947   testpmd> tso show (port_id)
948
949set port - gro
950~~~~~~~~~~~~~~
951
952Enable or disable GRO in ``csum`` forwarding engine::
953
954   testpmd> set port <port_id> gro on|off
955
956If enabled, the csum forwarding engine will perform GRO on the TCP/IPv4
957packets received from the given port.
958
959If disabled, packets received from the given port won't be performed
960GRO. By default, GRO is disabled for all ports.
961
962.. note::
963
964   When enable GRO for a port, TCP/IPv4 packets received from the port
965   will be performed GRO. After GRO, all merged packets have bad
966   checksums, since the GRO library doesn't re-calculate checksums for
967   the merged packets. Therefore, if users want the merged packets to
968   have correct checksums, please select HW IP checksum calculation and
969   HW TCP checksum calculation for the port which the merged packets are
970   transmitted to.
971
972show port - gro
973~~~~~~~~~~~~~~~
974
975Display GRO configuration for a given port::
976
977   testpmd> show port <port_id> gro
978
979set gro flush
980~~~~~~~~~~~~~
981
982Set the cycle to flush the GROed packets from reassembly tables::
983
984   testpmd> set gro flush <cycles>
985
986When enable GRO, the csum forwarding engine performs GRO on received
987packets, and the GROed packets are stored in reassembly tables. Users
988can use this command to determine when the GROed packets are flushed
989from the reassembly tables.
990
991The ``cycles`` is measured in GRO operation times. The csum forwarding
992engine flushes the GROed packets from the tables every ``cycles`` GRO
993operations.
994
995By default, the value of ``cycles`` is 1, which means flush GROed packets
996from the reassembly tables as soon as one GRO operation finishes. The value
997of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``.
998
999Please note that the large value of ``cycles`` may cause the poor TCP/IP
1000stack performance. Because the GROed packets are delayed to arrive the
1001stack, thus causing more duplicated ACKs and TCP retransmissions.
1002
1003set port - gso
1004~~~~~~~~~~~~~~
1005
1006Toggle per-port GSO support in ``csum`` forwarding engine::
1007
1008   testpmd> set port <port_id> gso on|off
1009
1010If enabled, the csum forwarding engine will perform GSO on supported IPv4
1011packets, transmitted on the given port.
1012
1013If disabled, packets transmitted on the given port will not undergo GSO.
1014By default, GSO is disabled for all ports.
1015
1016.. note::
1017
1018   When GSO is enabled on a port, supported IPv4 packets transmitted on that
1019   port undergo GSO. Afterwards, the segmented packets are represented by
1020   multi-segment mbufs; however, the csum forwarding engine doesn't calculation
1021   of checksums for GSO'd segments in SW. As a result, if users want correct
1022   checksums in GSO segments, they should enable HW checksum calculation for
1023   GSO-enabled ports.
1024
1025   For example, HW checksum calculation for VxLAN GSO'd packets may be enabled
1026   by setting the following options in the csum forwarding engine:
1027
1028   testpmd> csum set outer_ip hw <port_id>
1029
1030   testpmd> csum set ip hw <port_id>
1031
1032   testpmd> csum set tcp hw <port_id>
1033
1034set gso segsz
1035~~~~~~~~~~~~~
1036
1037Set the maximum GSO segment size (measured in bytes), which includes the
1038packet header and the packet payload for GSO-enabled ports (global)::
1039
1040   testpmd> set gso segsz <length>
1041
1042show port - gso
1043~~~~~~~~~~~~~~~

1447Port Functions
1448--------------
1449
1450The following sections show functions for configuring ports.
1451
1452.. note::
1453
1454   Port configuration changes only become active when forwarding is started/restarted.
1455
1456port attach
1457~~~~~~~~~~~
1458
1459Attach a port specified by pci address or virtual device args::
1460
1461   testpmd> port attach (identifier)
1462
1463To attach a new pci device, the device should be recognized by kernel first.
1464Then it should be moved under DPDK management.
1465Finally the port can be attached to testpmd.
1466
1467For example, to move a pci device using ixgbe under DPDK management:
1468
1469.. code-block:: console
1470
1471   # Check the status of the available devices.
1472   ./usertools/dpdk-devbind.py --status
1473
1474   Network devices using DPDK-compatible driver
1475   ============================================
1476   <none>
1477
1478   Network devices using kernel driver
1479   ===================================
1480   0000:0a:00.0 '82599ES 10-Gigabit' if=eth2 drv=ixgbe unused=
1481
1482
1483   # Bind the device to igb_uio.
1484   sudo ./usertools/dpdk-devbind.py -b igb_uio 0000:0a:00.0
1485
1486
1487   # Recheck the status of the devices.
1488   ./usertools/dpdk-devbind.py --status
1489   Network devices using DPDK-compatible driver
1490   ============================================
1491   0000:0a:00.0 '82599ES 10-Gigabit' drv=igb_uio unused=
1492
1493To attach a port created by virtual device, above steps are not needed.
1494
1495For example, to attach a port whose pci address is 0000:0a:00.0.
1496
1497.. code-block:: console
1498
1499   testpmd> port attach 0000:0a:00.0
1500   Attaching a new port...
1501   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
1502   EAL:   probe driver: 8086:10fb rte_ixgbe_pmd
1503   EAL:   PCI memory mapped at 0x7f83bfa00000
1504   EAL:   PCI memory mapped at 0x7f83bfa80000
1505   PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
1506   PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
1507   Port 0 is attached. Now total ports is 1
1508   Done
1509
1510For example, to attach a port created by pcap PMD.
1511
1512.. code-block:: console
1513
1514   testpmd> port attach net_pcap0
1515   Attaching a new port...
1516   PMD: Initializing pmd_pcap for net_pcap0
1517   PMD: Creating pcap-backed ethdev on numa socket 0
1518   Port 0 is attached. Now total ports is 1
1519   Done
1520
1521In this case, identifier is ``net_pcap0``.
1522This identifier format is the same as ``--vdev`` format of DPDK applications.
1523
1524For example, to re-attach a bonded port which has been previously detached,
1525the mode and slave parameters must be given.
1526
1527.. code-block:: console
1528
1529   testpmd> port attach net_bond_0,mode=0,slave=1
1530   Attaching a new port...
1531   EAL: Initializing pmd_bond for net_bond_0
1532   EAL: Create bonded device net_bond_0 on port 0 in mode 0 on socket 0.
1533   Port 0 is attached. Now total ports is 1
1534   Done
1535
1536
1537port detach
1538~~~~~~~~~~~
1539
1540Detach a specific port::
1541
1542   testpmd> port detach (port_id)
1543
1544Before detaching a port, the port should be stopped and closed.
1545
1546For example, to detach a pci device port 0.
1547
1548.. code-block:: console
1549
1550   testpmd> port stop 0
1551   Stopping ports...
1552   Done
1553   testpmd> port close 0
1554   Closing ports...
1555   Done
1556
1557   testpmd> port detach 0
1558   Detaching a port...
1559   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
1560   EAL:   remove driver: 8086:10fb rte_ixgbe_pmd
1561   EAL:   PCI memory unmapped at 0x7f83bfa00000
1562   EAL:   PCI memory unmapped at 0x7f83bfa80000
1563   Done
1564
1565
1566For example, to detach a virtual device port 0.
1567
1568.. code-block:: console
1569
1570   testpmd> port stop 0
1571   Stopping ports...
1572   Done
1573   testpmd> port close 0
1574   Closing ports...
1575   Done
1576
1577   testpmd> port detach 0
1578   Detaching a port...
1579   PMD: Closing pcap ethdev on numa socket 0
1580   Port 'net_pcap0' is detached. Now total ports is 0
1581   Done
1582
1583To remove a pci device completely from the system, first detach the port from testpmd.
1584Then the device should be moved under kernel management.
1585Finally the device can be removed using kernel pci hotplug functionality.
1586
1587For example, to move a pci device under kernel management:
1588
1589.. code-block:: console
1590
1591   sudo ./usertools/dpdk-devbind.py -b ixgbe 0000:0a:00.0
1592
1593   ./usertools/dpdk-devbind.py --status

1883
1884   testpmd> add bonding slave (slave id) (port id)
1885
1886For example, to add Ethernet device (port 6) to a Link Bonding device (port 10)::
1887
1888   testpmd> add bonding slave 6 10
1889
1890
1891remove bonding slave
1892~~~~~~~~~~~~~~~~~~~~
1893
1894Removes an Ethernet slave device from a Link Bonding device::
1895

2682.. _testpmd_flow_director:
2683
2684flow_director_filter
2685~~~~~~~~~~~~~~~~~~~~
2686
2687The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.
2688
2689Four types of filtering are supported which are referred to as Perfect Match, Signature, Perfect-mac-vlan and
2690Perfect-tunnel filters, the match mode is set by the ``--pkt-filter-mode`` command-line parameter:
2691
2692* Perfect match filters.
2693  The hardware checks a match between the masked fields of the received packets and the programmed filters.
2694  The masked fields are for IP flow.
2695
2696* Signature filters.
2697  The hardware checks a match between a hash-based signature of the masked fields of the received packet.
2698
2699* Perfect-mac-vlan match filters.
2700  The hardware checks a match between the masked fields of the received packets and the programmed filters.
2701  The masked fields are for MAC VLAN flow.
2702
2703* Perfect-tunnel match filters.
2704  The hardware checks a match between the masked fields of the received packets and the programmed filters.
2705  The masked fields are for tunnel flow.
2706
2707* Perfect-raw-flow-type match filters.
2708  The hardware checks a match between the masked fields of the received packets and pre-loaded raw (template) packet.
2709  The masked fields are specified by input sets.
2710
2711The Flow Director filters can match the different fields for different type of packet: flow type, specific input set
2712per flow type and the flexible payload.
2713
2714The Flow Director can also mask out parts of all of these fields so that filters
2715are only applied to certain fields or parts of the fields.
2716
2717Note that for raw flow type mode the source and destination fields in the
2718raw packet buffer need to be presented in a reversed order with respect
2719to the expected received packets.
2720For example: IP source and destination addresses or TCP/UDP/SCTP
2721source and destination ports
2722
2723Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information.

2942.. _testpmd_rte_flow:
2943
2944Flow rules management
2945---------------------
2946
2947Control of the generic flow API (*rte_flow*) is fully exposed through the
2948``flow`` command (validation, creation, destruction, queries and operation
2949modes).
2950
2951Considering *rte_flow* overlaps with all `Filter Functions`_, using both
2952features simultaneously may cause undefined side-effects and is therefore
2953not recommended.
2954
2955``flow`` syntax
2956~~~~~~~~~~~~~~~
2957
2958Because the ``flow`` command uses dynamic tokens to handle the large number
2959of possible flow rules combinations, its behavior differs slightly from
2960other commands, in particular:
2961
2962- Pressing *?* or the *<tab>* key displays contextual help for the current
2963  token, not that of the entire command.
2964
2965- Optional and repeated parameters are supported (provided they are listed
2966  in the contextual help).
2967
2968The first parameter stands for the operation mode. Possible operations and
2969their general syntax are described below. They are covered in detail in the
2970following sections.
2971
2972- Check whether a flow rule can be created::
2973
2974   flow validate {port_id}
2975       [group {group_id}] [priority {level}] [ingress] [egress]
2976       pattern {item} [/ {item} [...]] / end
2977       actions {action} [/ {action} [...]] / end
2978
2979- Create a flow rule::
2980
2981   flow create {port_id}
2982       [group {group_id}] [priority {level}] [ingress] [egress]
2983       pattern {item} [/ {item} [...]] / end
2984       actions {action} [/ {action} [...]] / end
2985
2986- Destroy specific flow rules::
2987
2988   flow destroy {port_id} rule {rule_id} [...]
2989
2990- Destroy all flow rules::
2991
2992   flow flush {port_id}
2993
2994- Query an existing flow rule::
2995
2996   flow query {port_id} {rule_id} {action}
2997
2998- List existing flow rules sorted by priority, filtered by group
2999  identifiers::
3000
3001   flow list {port_id} [group {group_id}] [...]
3002
3003- Restrict ingress traffic to the defined flow rules::
3004
3005   flow isolate {port_id} {boolean}
3006
3007Validating flow rules
3008~~~~~~~~~~~~~~~~~~~~~
3009
3010``flow validate`` reports whether a flow rule would be accepted by the
3011underlying device in its current state but stops short of creating it. It is
3012bound to ``rte_flow_validate()``::
3013
3014   flow validate {port_id}
3015      [group {group_id}] [priority {level}] [ingress] [egress]
3016      pattern {item} [/ {item} [...]] / end
3017      actions {action} [/ {action} [...]] / end
3018
3019If successful, it will show::
3020
3021   Flow rule validated
3022
3023Otherwise it will show an error message of the form::
3024
3025   Caught error type [...] ([...]): [...]
3026
3027This command uses the same parameters as ``flow create``, their format is
3028described in `Creating flow rules`_.
3029
3030Check whether redirecting any Ethernet packet received on port 0 to RX queue
3031index 6 is supported::
3032
3033   testpmd> flow validate 0 ingress pattern eth / end
3034      actions queue index 6 / end
3035   Flow rule validated
3036   testpmd>
3037
3038Port 0 does not support TCPv6 rules::
3039
3040   testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
3041      actions drop / end
3042   Caught error type 9 (specific pattern item): Invalid argument
3043   testpmd>
3044
3045Creating flow rules
3046~~~~~~~~~~~~~~~~~~~
3047
3048``flow create`` validates and creates the specified flow rule. It is bound
3049to ``rte_flow_create()``::
3050
3051   flow create {port_id}
3052      [group {group_id}] [priority {level}] [ingress] [egress]
3053      pattern {item} [/ {item} [...]] / end
3054      actions {action} [/ {action} [...]] / end
3055
3056If successful, it will return a flow rule ID usable with other commands::
3057
3058   Flow rule #[...] created
3059
3060Otherwise it will show an error message of the form::
3061
3062   Caught error type [...] ([...]): [...]
3063
3064Parameters describe in the following order:
3065
3066- Attributes (*group*, *priority*, *ingress*, *egress* tokens).
3067- A matching pattern, starting with the *pattern* token and terminated by an
3068  *end* pattern item.
3069- Actions, starting with the *actions* token and terminated by an *end*
3070  action.
3071
3072These translate directly to *rte_flow* objects provided as-is to the
3073underlying functions.
3074
3075The shortest valid definition only comprises mandatory tokens::
3076
3077   testpmd> flow create 0 pattern end actions end
3078
3079Note that PMDs may refuse rules that essentially do nothing such as this
3080one.
3081
3082**All unspecified object values are automatically initialized to 0.**
3083
3084Attributes
3085^^^^^^^^^^
3086
3087These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
3088specified before the ``pattern`` token.
3089
3090- ``group {group id}``: priority group.
3091- ``priority {level}``: priority level within group.
3092- ``ingress``: rule applies to ingress traffic.
3093- ``egress``: rule applies to egress traffic.
3094
3095Each instance of an attribute specified several times overrides the previous
3096value as shown below (group 4 is used)::
3097
3098   testpmd> flow create 0 group 42 group 24 group 4 [...]
3099
3100Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
3101
3102While not specifying a direction is an error, some rules may allow both
3103simultaneously.
3104
3105Most rules affect RX therefore contain the ``ingress`` token::
3106
3107   testpmd> flow create 0 ingress pattern [...]
3108
3109Matching pattern
3110^^^^^^^^^^^^^^^^
3111
3112A matching pattern starts after the ``pattern`` token. It is made of pattern
3113items and is terminated by a mandatory ``end`` item.
3114
3115Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
3116rte_flow_item_type``).
3117
3118The ``/`` token is used as a separator between pattern items as shown
3119below::
3120
3121   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
3122
3123Note that protocol items like these must be stacked from lowest to highest
3124layer to make sense. For instance, the following rule is either invalid or
3125unlikely to match any packet::
3126
3127   testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
3128
3129More information on these restrictions can be found in the *rte_flow*
3130documentation.
3131
3132Several items support additional specification structures, for example
3133``ipv4`` allows specifying source and destination addresses as follows::
3134
3135   testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
3136      dst is 10.2.0.0 / end [...]
3137
3138This rule matches all IPv4 traffic with the specified properties.
3139
3140In this example, ``src`` and ``dst`` are field names of the underlying
3141``struct rte_flow_item_ipv4`` object. All item properties can be specified
3142in a similar fashion.
3143
3144The ``is`` token means that the subsequent value must be matched exactly,
3145and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
3146accordingly. Possible assignment tokens are:
3147
3148- ``is``: match value perfectly (with full bit-mask).
3149- ``spec``: match value according to configured bit-mask.
3150- ``last``: specify upper bound to establish a range.
3151- ``mask``: specify bit-mask with relevant bits set to one.
3152- ``prefix``: generate bit-mask from a prefix length.
3153
3154These yield identical results::
3155
3156   ipv4 src is 10.1.1.1
3157
3158::
3159
3160   ipv4 src spec 10.1.1.1 src mask 255.255.255.255
3161
3162::
3163
3164   ipv4 src spec 10.1.1.1 src prefix 32
3165
3166::
3167
3168   ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
3169
3170::
3171
3172   ipv4 src is 10.1.1.1 src last 0 # 0 disables range
3173
3174Inclusive ranges can be defined with ``last``::
3175
3176   ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
3177
3178Note that ``mask`` affects both ``spec`` and ``last``::
3179
3180   ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0
3181      # matches 10.1.0.0 to 10.2.255.255
3182
3183Properties can be modified multiple times::
3184
3185   ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
3186
3187::
3188
3189   ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16
3190
3191Pattern items
3192^^^^^^^^^^^^^
3193
3194This section lists supported pattern items and their attributes, if any.
3195
3196- ``end``: end list of pattern items.
3197
3198- ``void``: no-op pattern item.
3199
3200- ``invert``: perform actions when pattern does not match.
3201
3202- ``any``: match any protocol for the current layer.
3203
3204  - ``num {unsigned}``: number of layers covered.
3205
3206- ``pf``: match packets addressed to the physical function.
3207
3208- ``vf``: match packets addressed to a virtual function ID.
3209

3310Actions list
3311^^^^^^^^^^^^
3312
3313A list of actions starts after the ``actions`` token in the same fashion as
3314`Matching pattern`_; actions are separated by ``/`` tokens and the list is
3315terminated by a mandatory ``end`` action.
3316
3317Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
3318rte_flow_action_type``).
3319
3320Dropping all incoming UDPv4 packets can be expressed as follows::
3321
3322   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3323      actions drop / end
3324
3325Several actions have configurable properties which must be specified when
3326there is no valid default value. For example, ``queue`` requires a target
3327queue index.
3328
3329This rule redirects incoming UDPv4 traffic to queue index 6::
3330
3331   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3332      actions queue index 6 / end
3333
3334While this one could be rejected by PMDs (unspecified queue index)::
3335
3336   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3337      actions queue / end
3338
3339As defined by *rte_flow*, the list is not ordered, all actions of a given
3340rule are performed simultaneously. These are equivalent::
3341
3342   queue index 6 / void / mark id 42 / end
3343
3344::
3345
3346   void / mark id 42 / queue index 6 / end
3347
3348All actions in a list should have different types, otherwise only the last
3349action of a given type is taken into account::
3350
3351   queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
3352
3353::
3354
3355   drop / drop / drop / end # drop is performed only once
3356
3357::
3358
3359   mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
3360
3361Considering they are performed simultaneously, opposite and overlapping
3362actions can sometimes be combined when the end result is unambiguous::
3363
3364   drop / queue index 6 / end # drop has no effect
3365
3366::
3367
3368   drop / dup index 6 / end # same as above
3369
3370::
3371
3372   queue index 6 / rss queues 6 7 8 / end # queue has no effect
3373
3374::
3375
3376   drop / passthru / end # drop has no effect
3377
3378Note that PMDs may still refuse such combinations.
3379
3380Actions
3381^^^^^^^
3382
3383This section lists supported actions and their attributes, if any.
3384
3385- ``end``: end list of actions.
3386
3387- ``void``: no-op action.
3388
3389- ``passthru``: let subsequent rule process matched packets.
3390
3391- ``mark``: attach 32 bit value to packets.
3392
3393  - ``id {unsigned}``: 32 bit value to return with packets.
3394
3395- ``flag``: flag packets.
3396
3397- ``queue``: assign packets to a given queue index.
3398
3399  - ``index {unsigned}``: queue index to use.
3400
3401- ``drop``: drop packets (note: passthru has priority).
3402
3403- ``count``: enable counters for this rule.
3404
3405- ``dup``: duplicate packets to a given queue index.
3406
3407  - ``index {unsigned}``: queue index to duplicate packets to.
3408
3409- ``rss``: spread packets among several queues.
3410
3411  - ``types [{RSS hash type} [...]] end``: RSS hash types, allowed tokens
3412    are the same as `set_hash_input_set`_, an empty list means none (0).
3413
3414  - ``key {string}``: RSS hash key, overrides ``key_len``.
3415
3416  - ``key_len {unsigned}``: RSS hash key length in bytes, can be used in
3417    conjunction with ``key`` to pad or truncate it.
3418
3419  - ``queues [{unsigned} [...]] end``: queue indices to use.
3420
3421- ``pf``: redirect packets to physical device function.
3422
3423- ``vf``: redirect packets to virtual device function.
3424
3425  - ``original {boolean}``: use original VF ID if possible.
3426  - ``id {unsigned}``: VF ID to redirect packets to.
3427
3428Destroying flow rules
3429~~~~~~~~~~~~~~~~~~~~~
3430
3431``flow destroy`` destroys one or more rules from their rule ID (as returned
3432by ``flow create``), this command calls ``rte_flow_destroy()`` as many
3433times as necessary::
3434
3435   flow destroy {port_id} rule {rule_id} [...]
3436
3437If successful, it will show::
3438
3439   Flow rule #[...] destroyed
3440
3441It does not report anything for rule IDs that do not exist. The usual error
3442message is shown when a rule cannot be destroyed::
3443
3444   Caught error type [...] ([...]): [...]
3445
3446``flow flush`` destroys all rules on a device and does not take extra
3447arguments. It is bound to ``rte_flow_flush()``::
3448
3449   flow flush {port_id}
3450
3451Any errors are reported as above.
3452
3453Creating several rules and destroying them::
3454
3455   testpmd> flow create 0 ingress pattern eth / ipv6 / end
3456      actions queue index 2 / end
3457   Flow rule #0 created
3458   testpmd> flow create 0 ingress pattern eth / ipv4 / end
3459      actions queue index 3 / end
3460   Flow rule #1 created
3461   testpmd> flow destroy 0 rule 0 rule 1
3462   Flow rule #1 destroyed
3463   Flow rule #0 destroyed
3464   testpmd>
3465
3466The same result can be achieved using ``flow flush``::
3467
3468   testpmd> flow create 0 ingress pattern eth / ipv6 / end
3469      actions queue index 2 / end
3470   Flow rule #0 created
3471   testpmd> flow create 0 ingress pattern eth / ipv4 / end
3472      actions queue index 3 / end
3473   Flow rule #1 created
3474   testpmd> flow flush 0
3475   testpmd>
3476
3477Non-existent rule IDs are ignored::
3478
3479   testpmd> flow create 0 ingress pattern eth / ipv6 / end
3480      actions queue index 2 / end
3481   Flow rule #0 created
3482   testpmd> flow create 0 ingress pattern eth / ipv4 / end
3483      actions queue index 3 / end
3484   Flow rule #1 created
3485   testpmd> flow destroy 0 rule 42 rule 10 rule 2
3486   testpmd>
3487   testpmd> flow destroy 0 rule 0
3488   Flow rule #0 destroyed
3489   testpmd>
3490
3491Querying flow rules
3492~~~~~~~~~~~~~~~~~~~
3493
3494``flow query`` queries a specific action of a flow rule having that
3495ability. Such actions collect information that can be reported using this
3496command. It is bound to ``rte_flow_query()``::
3497
3498   flow query {port_id} {rule_id} {action}
3499
3500If successful, it will display either the retrieved data for known actions
3501or the following message::
3502
3503   Cannot display result for action type [...] ([...])
3504
3505Otherwise, it will complain either that the rule does not exist or that some
3506error occurred::
3507
3508   Flow rule #[...] not found
3509
3510::
3511
3512   Caught error type [...] ([...]): [...]
3513
3514Currently only the ``count`` action is supported. This action reports the
3515number of packets that hit the flow rule and the total number of bytes. Its
3516output has the following format::
3517
3518   count:
3519    hits_set: [...] # whether "hits" contains a valid value
3520    bytes_set: [...] # whether "bytes" contains a valid value
3521    hits: [...] # number of packets
3522    bytes: [...] # number of bytes
3523
3524Querying counters for TCPv6 packets redirected to queue 6::
3525
3526   testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
3527      actions queue index 6 / count / end
3528   Flow rule #4 created
3529   testpmd> flow query 0 4 count
3530   count:
3531    hits_set: 1
3532    bytes_set: 0
3533    hits: 386446
3534    bytes: 0
3535   testpmd>
3536
3537Listing flow rules
3538~~~~~~~~~~~~~~~~~~
3539
3540``flow list`` lists existing flow rules sorted by priority and optionally
3541filtered by group identifiers::
3542
3543   flow list {port_id} [group {group_id}] [...]
3544
3545This command only fails with the following message if the device does not
3546exist::
3547
3548   Invalid port [...]
3549
3550Output consists of a header line followed by a short description of each
3551flow rule, one per line. There is no output at all when no flow rules are
3552configured on the device::
3553
3554   ID      Group   Prio    Attr    Rule
3555   [...]   [...]   [...]   [...]   [...]
3556
3557``Attr`` column flags:
3558
3559- ``i`` for ``ingress``.
3560- ``e`` for ``egress``.
3561
3562Creating several flow rules and listing them::
3563
3564   testpmd> flow create 0 ingress pattern eth / ipv4 / end
3565      actions queue index 6 / end
3566   Flow rule #0 created
3567   testpmd> flow create 0 ingress pattern eth / ipv6 / end
3568      actions queue index 2 / end
3569   Flow rule #1 created
3570   testpmd> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
3571      actions rss queues 6 7 8 end / end
3572   Flow rule #2 created
3573   testpmd> flow list 0
3574   ID      Group   Prio    Attr    Rule
3575   0       0       0       i-      ETH IPV4 => QUEUE
3576   1       0       0       i-      ETH IPV6 => QUEUE
3577   2       0       5       i-      ETH IPV4 UDP => RSS
3578   testpmd>
3579
3580Rules are sorted by priority (i.e. group ID first, then priority level)::
3581
3582   testpmd> flow list 1
3583   ID      Group   Prio    Attr    Rule
3584   0       0       0       i-      ETH => COUNT
3585   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
3586   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
3587   1       24      0       i-      ETH IPV4 UDP => QUEUE
3588   4       24      10      i-      ETH IPV4 TCP => DROP
3589   3       24      20      i-      ETH IPV4 => DROP
3590   2       24      42      i-      ETH IPV4 UDP => QUEUE
3591   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
3592   testpmd>
3593
3594Output can be limited to specific groups::
3595
3596   testpmd> flow list 1 group 0 group 63
3597   ID      Group   Prio    Attr    Rule
3598   0       0       0       i-      ETH => COUNT
3599   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
3600   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
3601   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
3602   testpmd>
3603
3604Toggling isolated mode
3605~~~~~~~~~~~~~~~~~~~~~~
3606
3607``flow isolate`` can be used to tell the underlying PMD that ingress traffic
3608must only be injected from the defined flow rules; that no default traffic
3609is expected outside those rules and the driver is free to assign more
3610resources to handle them. It is bound to ``rte_flow_isolate()``::
3611
3612 flow isolate {port_id} {boolean}
3613
3614If successful, enabling or disabling isolated mode shows either::
3615
3616 Ingress traffic on port [...]
3617    is now restricted to the defined flow rules
3618
3619Or::
3620
3621 Ingress traffic on port [...]
3622    is not restricted anymore to the defined flow rules
3623
3624Otherwise, in case of error::
3625
3626   Caught error type [...] ([...]): [...]
3627
3628Mainly due to its side effects, PMDs supporting this mode may not have the
3629ability to toggle it more than once without reinitializing affected ports
3630first (e.g. by exiting testpmd).
3631
3632Enabling isolated mode::
3633
3634 testpmd> flow isolate 0 true
3635 Ingress traffic on port 0 is now restricted to the defined flow rules
3636 testpmd>
3637
3638Disabling isolated mode::
3639
3640 testpmd> flow isolate 0 false
3641 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
3642 testpmd>
3643
3644Sample QinQ flow rules
3645~~~~~~~~~~~~~~~~~~~~~~
3646
3647Before creating QinQ rule(s) the following commands should be issued to enable QinQ::
3648
3649   testpmd> port stop 0
3650   testpmd> vlan set qinq on 0
3651
3652The above command sets the inner and outer TPID's to 0x8100.
3653
3654To change the TPID's the following commands should be used::
3655
3656   testpmd> vlan set outer tpid 0xa100 0
3657   testpmd> vlan set inner tpid 0x9100 0
3658   testpmd> port start 0
3659
3660Validate and create a QinQ rule on port 0 to steer traffic to a VF queue in a VM.
3661
3662::
3663
3664   testpmd> flow validate 0 ingress pattern eth / vlan tci is 123 /
3665       vlan tci is 456 / end actions vf id 1 / queue index 0 / end
3666   Flow rule #0 validated
3667
3668   testpmd> flow create 0 ingress pattern eth / vlan tci is 4 /
3669       vlan tci is 456 / end actions vf id 123 / queue index 0 / end
3670   Flow rule #0 created
3671
3672   testpmd> flow list 0
3673   ID      Group   Prio    Attr    Rule
3674   0       0       0       i-      ETH VLAN VLAN=>VF QUEUE
3675
3676Validate and create a QinQ rule on port 0 to steer traffic to a queue on the host.
3677
3678::
3679
3680   testpmd> flow validate 0 ingress pattern eth / vlan tci is 321 /
3681        vlan tci is 654 / end actions pf / queue index 0 / end
3682   Flow rule #1 validated
3683
3684   testpmd> flow create 0 ingress pattern eth / vlan tci is 321 /
3685        vlan tci is 654 / end actions pf / queue index 1 / end
3686   Flow rule #1 created
3687
3688   testpmd> flow list 0
3689   ID      Group   Prio    Attr    Rule
3690   0       0       0       i-      ETH VLAN VLAN=>VF QUEUE
3691   1       0       0       i-      ETH VLAN VLAN=>PF QUEUE
3692
