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)
484
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

1898Adds Ethernet device to a Link Bonding device::
1899
1900   testpmd> add bonding slave (slave id) (port id)
1901
1902For example, to add Ethernet device (port 6) to a Link Bonding device (port 10)::
1903
1904   testpmd> add bonding slave 6 10
1905
1906
1907remove bonding slave
1908~~~~~~~~~~~~~~~~~~~~
1909
1910Removes an Ethernet slave device from a Link Bonding device::
1911
1912   testpmd> remove bonding slave (slave id) (port id)
1913
1914For example, to remove Ethernet slave device (port 6) to a Link Bonding device (port 10)::

2698.. _testpmd_flow_director:
2699
2700flow_director_filter
2701~~~~~~~~~~~~~~~~~~~~
2702
2703The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.
2704
2705Four types of filtering are supported which are referred to as Perfect Match, Signature, Perfect-mac-vlan and
2706Perfect-tunnel filters, the match mode is set by the ``--pkt-filter-mode`` command-line parameter:
2707
2708* Perfect match filters.
2709  The hardware checks a match between the masked fields of the received packets and the programmed filters.
2710  The masked fields are for IP flow.
2711
2712* Signature filters.
2713  The hardware checks a match between a hash-based signature of the masked fields of the received packet.
2714
2715* Perfect-mac-vlan match filters.
2716  The hardware checks a match between the masked fields of the received packets and the programmed filters.
2717  The masked fields are for MAC VLAN flow.
2718
2719* Perfect-tunnel match filters.
2720  The hardware checks a match between the masked fields of the received packets and the programmed filters.
2721  The masked fields are for tunnel flow.
2722
2723* Perfect-raw-flow-type match filters.
2724  The hardware checks a match between the masked fields of the received packets and pre-loaded raw (template) packet.
2725  The masked fields are specified by input sets.
2726
2727The Flow Director filters can match the different fields for different type of packet: flow type, specific input set
2728per flow type and the flexible payload.
2729
2730The Flow Director can also mask out parts of all of these fields so that filters
2731are only applied to certain fields or parts of the fields.
2732
2733Note that for raw flow type mode the source and destination fields in the
2734raw packet buffer need to be presented in a reversed order with respect
2735to the expected received packets.
2736For example: IP source and destination addresses or TCP/UDP/SCTP
2737source and destination ports
2738
2739Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information.

2959
2960Flow rules management
2961---------------------
2962
2963Control of the generic flow API (*rte_flow*) is fully exposed through the
2964``flow`` command (validation, creation, destruction, queries and operation
2965modes).
2966
2967Considering *rte_flow* overlaps with all `Filter Functions`_, using both
2968features simultaneously may cause undefined side-effects and is therefore
2969not recommended.
2970
2971``flow`` syntax
2972~~~~~~~~~~~~~~~
2973
2974Because the ``flow`` command uses dynamic tokens to handle the large number
2975of possible flow rules combinations, its behavior differs slightly from
2976other commands, in particular:
2977
2978- Pressing *?* or the *<tab>* key displays contextual help for the current
2979  token, not that of the entire command.
2980
2981- Optional and repeated parameters are supported (provided they are listed
2982  in the contextual help).
2983
2984The first parameter stands for the operation mode. Possible operations and
2985their general syntax are described below. They are covered in detail in the
2986following sections.
2987
2988- Check whether a flow rule can be created::
2989
2990   flow validate {port_id}
2991       [group {group_id}] [priority {level}] [ingress] [egress]
2992       pattern {item} [/ {item} [...]] / end
2993       actions {action} [/ {action} [...]] / end
2994
2995- Create a flow rule::
2996
2997   flow create {port_id}
2998       [group {group_id}] [priority {level}] [ingress] [egress]
2999       pattern {item} [/ {item} [...]] / end
3000       actions {action} [/ {action} [...]] / end
3001
3002- Destroy specific flow rules::
3003
3004   flow destroy {port_id} rule {rule_id} [...]
3005
3006- Destroy all flow rules::
3007
3008   flow flush {port_id}
3009
3010- Query an existing flow rule::
3011
3012   flow query {port_id} {rule_id} {action}
3013
3014- List existing flow rules sorted by priority, filtered by group
3015  identifiers::
3016
3017   flow list {port_id} [group {group_id}] [...]
3018
3019- Restrict ingress traffic to the defined flow rules::
3020
3021   flow isolate {port_id} {boolean}
3022
3023Validating flow rules
3024~~~~~~~~~~~~~~~~~~~~~
3025
3026``flow validate`` reports whether a flow rule would be accepted by the
3027underlying device in its current state but stops short of creating it. It is
3028bound to ``rte_flow_validate()``::
3029
3030   flow validate {port_id}
3031      [group {group_id}] [priority {level}] [ingress] [egress]
3032      pattern {item} [/ {item} [...]] / end
3033      actions {action} [/ {action} [...]] / end
3034
3035If successful, it will show::
3036
3037   Flow rule validated
3038
3039Otherwise it will show an error message of the form::
3040
3041   Caught error type [...] ([...]): [...]
3042
3043This command uses the same parameters as ``flow create``, their format is
3044described in `Creating flow rules`_.
3045
3046Check whether redirecting any Ethernet packet received on port 0 to RX queue
3047index 6 is supported::
3048
3049   testpmd> flow validate 0 ingress pattern eth / end
3050      actions queue index 6 / end
3051   Flow rule validated
3052   testpmd>
3053
3054Port 0 does not support TCPv6 rules::
3055
3056   testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
3057      actions drop / end
3058   Caught error type 9 (specific pattern item): Invalid argument
3059   testpmd>
3060
3061Creating flow rules
3062~~~~~~~~~~~~~~~~~~~
3063
3064``flow create`` validates and creates the specified flow rule. It is bound
3065to ``rte_flow_create()``::
3066
3067   flow create {port_id}
3068      [group {group_id}] [priority {level}] [ingress] [egress]
3069      pattern {item} [/ {item} [...]] / end
3070      actions {action} [/ {action} [...]] / end
3071
3072If successful, it will return a flow rule ID usable with other commands::
3073
3074   Flow rule #[...] created
3075
3076Otherwise it will show an error message of the form::
3077
3078   Caught error type [...] ([...]): [...]
3079
3080Parameters describe in the following order:
3081
3082- Attributes (*group*, *priority*, *ingress*, *egress* tokens).
3083- A matching pattern, starting with the *pattern* token and terminated by an
3084  *end* pattern item.
3085- Actions, starting with the *actions* token and terminated by an *end*
3086  action.
3087
3088These translate directly to *rte_flow* objects provided as-is to the
3089underlying functions.
3090
3091The shortest valid definition only comprises mandatory tokens::
3092
3093   testpmd> flow create 0 pattern end actions end
3094
3095Note that PMDs may refuse rules that essentially do nothing such as this
3096one.
3097
3098**All unspecified object values are automatically initialized to 0.**
3099
3100Attributes
3101^^^^^^^^^^
3102
3103These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
3104specified before the ``pattern`` token.
3105
3106- ``group {group id}``: priority group.
3107- ``priority {level}``: priority level within group.
3108- ``ingress``: rule applies to ingress traffic.
3109- ``egress``: rule applies to egress traffic.
3110
3111Each instance of an attribute specified several times overrides the previous
3112value as shown below (group 4 is used)::
3113
3114   testpmd> flow create 0 group 42 group 24 group 4 [...]
3115
3116Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
3117
3118While not specifying a direction is an error, some rules may allow both
3119simultaneously.
3120
3121Most rules affect RX therefore contain the ``ingress`` token::
3122
3123   testpmd> flow create 0 ingress pattern [...]
3124
3125Matching pattern
3126^^^^^^^^^^^^^^^^
3127
3128A matching pattern starts after the ``pattern`` token. It is made of pattern
3129items and is terminated by a mandatory ``end`` item.
3130
3131Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
3132rte_flow_item_type``).
3133
3134The ``/`` token is used as a separator between pattern items as shown
3135below::
3136
3137   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
3138
3139Note that protocol items like these must be stacked from lowest to highest
3140layer to make sense. For instance, the following rule is either invalid or
3141unlikely to match any packet::
3142
3143   testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
3144
3145More information on these restrictions can be found in the *rte_flow*
3146documentation.
3147
3148Several items support additional specification structures, for example
3149``ipv4`` allows specifying source and destination addresses as follows::
3150
3151   testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
3152      dst is 10.2.0.0 / end [...]
3153
3154This rule matches all IPv4 traffic with the specified properties.
3155
3156In this example, ``src`` and ``dst`` are field names of the underlying
3157``struct rte_flow_item_ipv4`` object. All item properties can be specified
3158in a similar fashion.
3159
3160The ``is`` token means that the subsequent value must be matched exactly,
3161and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
3162accordingly. Possible assignment tokens are:
3163
3164- ``is``: match value perfectly (with full bit-mask).
3165- ``spec``: match value according to configured bit-mask.
3166- ``last``: specify upper bound to establish a range.
3167- ``mask``: specify bit-mask with relevant bits set to one.
3168- ``prefix``: generate bit-mask from a prefix length.
3169
3170These yield identical results::
3171
3172   ipv4 src is 10.1.1.1
3173
3174::
3175
3176   ipv4 src spec 10.1.1.1 src mask 255.255.255.255
3177
3178::
3179
3180   ipv4 src spec 10.1.1.1 src prefix 32
3181
3182::
3183
3184   ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
3185
3186::
3187
3188   ipv4 src is 10.1.1.1 src last 0 # 0 disables range
3189
3190Inclusive ranges can be defined with ``last``::
3191
3192   ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
3193
3194Note that ``mask`` affects both ``spec`` and ``last``::
3195
3196   ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0
3197      # matches 10.1.0.0 to 10.2.255.255
3198
3199Properties can be modified multiple times::
3200
3201   ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
3202
3203::
3204
3205   ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16
3206
3207Pattern items
3208^^^^^^^^^^^^^
3209
3210This section lists supported pattern items and their attributes, if any.
3211
3212- ``end``: end list of pattern items.
3213

3326Actions list
3327^^^^^^^^^^^^
3328
3329A list of actions starts after the ``actions`` token in the same fashion as
3330`Matching pattern`_; actions are separated by ``/`` tokens and the list is
3331terminated by a mandatory ``end`` action.
3332
3333Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
3334rte_flow_action_type``).
3335
3336Dropping all incoming UDPv4 packets can be expressed as follows::
3337
3338   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3339      actions drop / end
3340
3341Several actions have configurable properties which must be specified when
3342there is no valid default value. For example, ``queue`` requires a target
3343queue index.
3344
3345This rule redirects incoming UDPv4 traffic to queue index 6::
3346
3347   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3348      actions queue index 6 / end
3349
3350While this one could be rejected by PMDs (unspecified queue index)::
3351
3352   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3353      actions queue / end
3354
3355As defined by *rte_flow*, the list is not ordered, all actions of a given
3356rule are performed simultaneously. These are equivalent::
3357
3358   queue index 6 / void / mark id 42 / end
3359
3360::
3361
3362   void / mark id 42 / queue index 6 / end
3363
3364All actions in a list should have different types, otherwise only the last
3365action of a given type is taken into account::
3366
3367   queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
3368
3369::
3370
3371   drop / drop / drop / end # drop is performed only once
3372
3373::
3374
3375   mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
3376
3377Considering they are performed simultaneously, opposite and overlapping
3378actions can sometimes be combined when the end result is unambiguous::
3379
3380   drop / queue index 6 / end # drop has no effect
3381
3382::
3383
3384   drop / dup index 6 / end # same as above
3385
3386::
3387
3388   queue index 6 / rss queues 6 7 8 / end # queue has no effect
3389
3390::
3391
3392   drop / passthru / end # drop has no effect
3393
3394Note that PMDs may still refuse such combinations.
3395
3396Actions
3397^^^^^^^
3398
3399This section lists supported actions and their attributes, if any.
3400
3401- ``end``: end list of actions.
3402
3403- ``void``: no-op action.
3404
3405- ``passthru``: let subsequent rule process matched packets.
3406
3407- ``mark``: attach 32 bit value to packets.
3408
3409  - ``id {unsigned}``: 32 bit value to return with packets.
3410
3411- ``flag``: flag packets.
3412
3413- ``queue``: assign packets to a given queue index.
3414
3415  - ``index {unsigned}``: queue index to use.
3416
3417- ``drop``: drop packets (note: passthru has priority).
3418
3419- ``count``: enable counters for this rule.
3420
3421- ``dup``: duplicate packets to a given queue index.
3422
3423  - ``index {unsigned}``: queue index to duplicate packets to.
3424
3425- ``rss``: spread packets among several queues.
3426
3427  - ``types [{RSS hash type} [...]] end``: RSS hash types, allowed tokens
3428    are the same as `set_hash_input_set`_, an empty list means none (0).
3429
3430  - ``key {string}``: RSS hash key, overrides ``key_len``.
3431
3432  - ``key_len {unsigned}``: RSS hash key length in bytes, can be used in
3433    conjunction with ``key`` to pad or truncate it.
3434
3435  - ``queues [{unsigned} [...]] end``: queue indices to use.
3436
3437- ``pf``: redirect packets to physical device function.
3438
3439- ``vf``: redirect packets to virtual device function.
3440
3441  - ``original {boolean}``: use original VF ID if possible.
3442  - ``id {unsigned}``: VF ID to redirect packets to.
3443
3444Destroying flow rules
3445~~~~~~~~~~~~~~~~~~~~~
3446
3447``flow destroy`` destroys one or more rules from their rule ID (as returned
3448by ``flow create``), this command calls ``rte_flow_destroy()`` as many
3449times as necessary::
3450
3451   flow destroy {port_id} rule {rule_id} [...]
3452
3453If successful, it will show::
3454
3455   Flow rule #[...] destroyed
3456
3457It does not report anything for rule IDs that do not exist. The usual error
3458message is shown when a rule cannot be destroyed::
3459
3460   Caught error type [...] ([...]): [...]
3461
3462``flow flush`` destroys all rules on a device and does not take extra
3463arguments. It is bound to ``rte_flow_flush()``::
3464
3465   flow flush {port_id}
3466
3467Any errors are reported as above.
3468
3469Creating several rules and destroying them::
3470
3471   testpmd> flow create 0 ingress pattern eth / ipv6 / end
3472      actions queue index 2 / end
3473   Flow rule #0 created
3474   testpmd> flow create 0 ingress pattern eth / ipv4 / end
3475      actions queue index 3 / end
3476   Flow rule #1 created
3477   testpmd> flow destroy 0 rule 0 rule 1
3478   Flow rule #1 destroyed
3479   Flow rule #0 destroyed
3480   testpmd>
3481
3482The same result can be achieved using ``flow flush``::
3483
3484   testpmd> flow create 0 ingress pattern eth / ipv6 / end
3485      actions queue index 2 / end
3486   Flow rule #0 created
3487   testpmd> flow create 0 ingress pattern eth / ipv4 / end
3488      actions queue index 3 / end
3489   Flow rule #1 created
3490   testpmd> flow flush 0
3491   testpmd>
3492
3493Non-existent rule IDs are ignored::
3494
3495   testpmd> flow create 0 ingress pattern eth / ipv6 / end
3496      actions queue index 2 / end
3497   Flow rule #0 created
3498   testpmd> flow create 0 ingress pattern eth / ipv4 / end
3499      actions queue index 3 / end
3500   Flow rule #1 created
3501   testpmd> flow destroy 0 rule 42 rule 10 rule 2
3502   testpmd>
3503   testpmd> flow destroy 0 rule 0
3504   Flow rule #0 destroyed
3505   testpmd>
3506
3507Querying flow rules
3508~~~~~~~~~~~~~~~~~~~
3509
3510``flow query`` queries a specific action of a flow rule having that
3511ability. Such actions collect information that can be reported using this
3512command. It is bound to ``rte_flow_query()``::
3513
3514   flow query {port_id} {rule_id} {action}
3515
3516If successful, it will display either the retrieved data for known actions
3517or the following message::
3518
3519   Cannot display result for action type [...] ([...])
3520
3521Otherwise, it will complain either that the rule does not exist or that some
3522error occurred::
3523
3524   Flow rule #[...] not found
3525
3526::
3527
3528   Caught error type [...] ([...]): [...]
3529
3530Currently only the ``count`` action is supported. This action reports the
3531number of packets that hit the flow rule and the total number of bytes. Its
3532output has the following format::
3533
3534   count:
3535    hits_set: [...] # whether "hits" contains a valid value
3536    bytes_set: [...] # whether "bytes" contains a valid value
3537    hits: [...] # number of packets
3538    bytes: [...] # number of bytes
3539
3540Querying counters for TCPv6 packets redirected to queue 6::
3541
3542   testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
3543      actions queue index 6 / count / end
3544   Flow rule #4 created
3545   testpmd> flow query 0 4 count
3546   count:
3547    hits_set: 1
3548    bytes_set: 0
3549    hits: 386446
3550    bytes: 0
3551   testpmd>
3552
3553Listing flow rules
3554~~~~~~~~~~~~~~~~~~
3555
3556``flow list`` lists existing flow rules sorted by priority and optionally
3557filtered by group identifiers::
3558
3559   flow list {port_id} [group {group_id}] [...]
3560
3561This command only fails with the following message if the device does not
3562exist::
3563
3564   Invalid port [...]
3565
3566Output consists of a header line followed by a short description of each
3567flow rule, one per line. There is no output at all when no flow rules are
3568configured on the device::
3569
3570   ID      Group   Prio    Attr    Rule
3571   [...]   [...]   [...]   [...]   [...]
3572
3573``Attr`` column flags:
3574
3575- ``i`` for ``ingress``.
3576- ``e`` for ``egress``.
3577
3578Creating several flow rules and listing them::
3579
3580   testpmd> flow create 0 ingress pattern eth / ipv4 / end
3581      actions queue index 6 / end
3582   Flow rule #0 created
3583   testpmd> flow create 0 ingress pattern eth / ipv6 / end
3584      actions queue index 2 / end
3585   Flow rule #1 created
3586   testpmd> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
3587      actions rss queues 6 7 8 end / end
3588   Flow rule #2 created
3589   testpmd> flow list 0
3590   ID      Group   Prio    Attr    Rule
3591   0       0       0       i-      ETH IPV4 => QUEUE
3592   1       0       0       i-      ETH IPV6 => QUEUE
3593   2       0       5       i-      ETH IPV4 UDP => RSS
3594   testpmd>
3595
3596Rules are sorted by priority (i.e. group ID first, then priority level)::
3597
3598   testpmd> flow list 1
3599   ID      Group   Prio    Attr    Rule
3600   0       0       0       i-      ETH => COUNT
3601   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
3602   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
3603   1       24      0       i-      ETH IPV4 UDP => QUEUE
3604   4       24      10      i-      ETH IPV4 TCP => DROP
3605   3       24      20      i-      ETH IPV4 => DROP
3606   2       24      42      i-      ETH IPV4 UDP => QUEUE
3607   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
3608   testpmd>
3609
3610Output can be limited to specific groups::
3611
3612   testpmd> flow list 1 group 0 group 63
3613   ID      Group   Prio    Attr    Rule
3614   0       0       0       i-      ETH => COUNT
3615   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
3616   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
3617   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
3618   testpmd>
3619
3620Toggling isolated mode
3621~~~~~~~~~~~~~~~~~~~~~~
3622
3623``flow isolate`` can be used to tell the underlying PMD that ingress traffic
3624must only be injected from the defined flow rules; that no default traffic
3625is expected outside those rules and the driver is free to assign more
3626resources to handle them. It is bound to ``rte_flow_isolate()``::
3627
3628 flow isolate {port_id} {boolean}
3629
3630If successful, enabling or disabling isolated mode shows either::
3631
3632 Ingress traffic on port [...]
3633    is now restricted to the defined flow rules
3634
3635Or::
3636
3637 Ingress traffic on port [...]
3638    is not restricted anymore to the defined flow rules
3639
3640Otherwise, in case of error::
3641
3642   Caught error type [...] ([...]): [...]
3643
3644Mainly due to its side effects, PMDs supporting this mode may not have the
3645ability to toggle it more than once without reinitializing affected ports
3646first (e.g. by exiting testpmd).
3647
3648Enabling isolated mode::
3649
3650 testpmd> flow isolate 0 true
3651 Ingress traffic on port 0 is now restricted to the defined flow rules
3652 testpmd>
3653
3654Disabling isolated mode::
3655
3656 testpmd> flow isolate 0 false
3657 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
3658 testpmd>
3659
3660Sample QinQ flow rules
3661~~~~~~~~~~~~~~~~~~~~~~
3662
3663Before creating QinQ rule(s) the following commands should be issued to enable QinQ::
3664
3665   testpmd> port stop 0
3666   testpmd> vlan set qinq on 0
3667
3668The above command sets the inner and outer TPID's to 0x8100.
3669
3670To change the TPID's the following commands should be used::
3671
3672   testpmd> vlan set outer tpid 0xa100 0
3673   testpmd> vlan set inner tpid 0x9100 0
3674   testpmd> port start 0
3675
3676Validate and create a QinQ rule on port 0 to steer traffic to a VF queue in a VM.
3677
3678::
3679
3680   testpmd> flow validate 0 ingress pattern eth / vlan tci is 123 /
3681       vlan tci is 456 / end actions vf id 1 / queue index 0 / end
3682   Flow rule #0 validated
3683
3684   testpmd> flow create 0 ingress pattern eth / vlan tci is 4 /
3685       vlan tci is 456 / end actions vf id 123 / queue index 0 / end
3686   Flow rule #0 created
3687
3688   testpmd> flow list 0
3689   ID      Group   Prio    Attr    Rule
3690   0       0       0       i-      ETH VLAN VLAN=>VF QUEUE
3691
3692Validate and create a QinQ rule on port 0 to steer traffic to a queue on the host.
3693
3694::
3695
3696   testpmd> flow validate 0 ingress pattern eth / vlan tci is 321 /
3697        vlan tci is 654 / end actions pf / queue index 0 / end
3698   Flow rule #1 validated
3699
3700   testpmd> flow create 0 ingress pattern eth / vlan tci is 321 /
3701        vlan tci is 654 / end actions pf / queue index 1 / end
3702   Flow rule #1 created
3703
3704   testpmd> flow list 0
3705   ID      Group   Prio    Attr    Rule
3706   0       0       0       i-      ETH VLAN VLAN=>VF QUEUE
3707   1       0       0       i-      ETH VLAN VLAN=>PF QUEUE
3708
