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 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.

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   ./dpdk-testpmd -n4 -r2 ... -- -i --cmdline-file=/home/ubuntu/flow-create-commands.txt

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.

301   nb forwarding cores=2 - nb forwarding ports=1
302   RX queues=1 - RX desc=128 - RX free threshold=0
303   RX threshold registers: pthresh=8 hthresh=8 wthresh=4
304   TX queues=1 - TX desc=512 - TX free threshold=0
305   TX threshold registers: pthresh=36 hthresh=0 wthresh=0
306   TX RS bit threshold=0 - TXQ flags=0x0
307
308set fwd
309~~~~~~~
310
311Set the packet forwarding mode::
312
313   testpmd> set fwd (io|mac|macswap|flowgen| \
314                     rxonly|txonly|csum|icmpecho|noisy|5tswap) (""|retry)
315
316``retry`` can be specified for forwarding engines except ``rx_only``.
317
318The available information categories are:
319
320* ``io``: Forwards packets "as-is" in I/O mode.
321  This is the fastest possible forwarding operation as it does not access packets data.
322  This is the default mode.
323
324* ``mac``: Changes the source and the destination Ethernet addresses of packets before forwarding them.
325  Default application behavior is to set source Ethernet address to that of the transmitting interface, and destination
326  address to a dummy value (set during init). The user may specify a target destination Ethernet address via the 'eth-peer' or
327  'eth-peers-configfile' command-line options. It is not currently possible to specify a specific source Ethernet address.
328
329* ``macswap``: MAC swap forwarding mode.
330  Swaps the source and the destination Ethernet addresses of packets before forwarding them.
331
332* ``flowgen``: Multi-flow generation mode.
333  Originates a number of flows (with varying destination IP addresses), and terminate receive traffic.
334
335* ``rxonly``: Receives packets but doesn't transmit them.
336
337* ``txonly``: Generates and transmits packets without receiving any.
338
339* ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet.
340
341* ``icmpecho``: Receives a burst of packets, lookup for ICMP echo requests and, if any, send back ICMP echo replies.
342
343* ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX.
344
345* ``noisy``: Noisy neighbor simulation.
346  Simulate more realistic behavior of a guest machine engaged in receiving
347  and sending packets performing Virtual Network Function (VNF).
348
349* ``5tswap``: Swap the source and destination of L2,L3,L4 if they exist.
350
351  L2 swaps the source address and destination address of Ethernet, as same as ``macswap``.
352
353  L3 swaps the source address and destination address of IP (v4 and v6).
354
355  L4 swaps the source port and destination port of transport layer (TCP and UDP).
356
357Example::
358
359   testpmd> set fwd rxonly
360
361   Set rxonly packet forwarding mode
362
363
364show fwd
365~~~~~~~~
366
367When running, forwarding engines maintain statistics from the time they have been started.

636Configuration Functions
637-----------------------
638
639The testpmd application can be configured from the runtime as well as from the command-line.
640
641This section details the available configuration functions that are available.
642
643.. note::
644
645   Configuration changes only become active when forwarding is started/restarted.
646
647set default
648~~~~~~~~~~~
649
650Reset forwarding to the default configuration::
651
652   testpmd> set default
653
654set verbose
655~~~~~~~~~~~
656
657Set the debug verbosity level::
658
659   testpmd> set verbose (level)
660
661Available levels are as following:
662
663* ``0`` silent except for error.
664* ``1`` fully verbose except for Tx packets.
665* ``2`` fully verbose except for Rx packets.
666* ``> 2`` fully verbose.
667
668set log
669~~~~~~~
670
671Set the log level for a log type::
672
673	testpmd> set log global|(type) (level)
674
675Where:
676
677* ``type`` is the log name.
678
679* ``level`` is the log level.
680
681For example, to change the global log level::
682
683	testpmd> set log global (level)
684
685Regexes can also be used for type. To change log level of user1, user2 and user3::
686
687	testpmd> set log user[1-3] (level)
688
689set nbport
690~~~~~~~~~~
691
692Set the number of ports used by the application:
693
694set nbport (num)
695
696This is equivalent to the ``--nb-ports`` command-line option.
697
698set nbcore
699~~~~~~~~~~
700
701Set the number of cores used by the application::
702
703   testpmd> set nbcore (num)
704
705This is equivalent to the ``--nb-cores`` command-line option.
706
707.. note::
708
709   The number of cores used must not be greater than number of ports used multiplied by the number of queues per port.
710
711set coremask
712~~~~~~~~~~~~
713
714Set the forwarding cores hexadecimal mask::
715
716   testpmd> set coremask (mask)
717
718This is equivalent to the ``--coremask`` command-line option.
719
720.. note::
721
722   The main lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
723
724set portmask
725~~~~~~~~~~~~
726
727Set the forwarding ports hexadecimal mask::
728
729   testpmd> set portmask (mask)
730
731This is equivalent to the ``--portmask`` command-line option.
732
733set record-core-cycles
734~~~~~~~~~~~~~~~~~~~~~~
735
736Set the recording of CPU cycles::
737
738   testpmd> set record-core-cycles (on|off)
739
740Where:
741
742* ``on`` enables measurement of CPU cycles per packet.
743
744* ``off`` disables measurement of CPU cycles per packet.
745
746This is equivalent to the ``--record-core-cycles command-line`` option.
747
748set record-burst-stats
749~~~~~~~~~~~~~~~~~~~~~~
750
751Set the displaying of RX and TX bursts::
752
753   testpmd> set record-burst-stats (on|off)
754
755Where:
756
757* ``on`` enables display of RX and TX bursts.
758
759* ``off`` disables display of RX and TX bursts.
760
761This is equivalent to the ``--record-burst-stats command-line`` option.
762
763set burst
764~~~~~~~~~
765
766Set number of packets per burst::
767
768   testpmd> set burst (num)
769
770This is equivalent to the ``--burst command-line`` option.
771
772When retry is enabled, the transmit delay time and number of retries can also be set::
773
774   testpmd> set burst tx delay (microseconds) retry (num)
775
776set rxoffs
777~~~~~~~~~~
778
779Set the offsets of segments relating to the data buffer beginning on receiving
780if split feature is engaged. Affects only the queues configured with split
781offloads (currently BUFFER_SPLIT is supported only).
782
783   testpmd> set rxoffs (x[,y]*)
784
785Where x[,y]* represents a CSV list of values, without white space. If the list
786of offsets is shorter than the list of segments the zero offsets will be used
787for the remaining segments.
788
789set rxpkts
790~~~~~~~~~~
791
792Set the length of segments to scatter packets on receiving if split
793feature is engaged. Affects only the queues configured with split offloads
794(currently BUFFER_SPLIT is supported only). Optionally the multiple memory
795pools can be specified with --mbuf-size command line parameter and the mbufs
796to receive will be allocated sequentially from these extra memory pools (the
797mbuf for the first segment is allocated from the first pool, the second one
798from the second pool, and so on, if segment number is greater then pool's the
799mbuf for remaining segments will be allocated from the last valid pool).
800
801   testpmd> set rxpkts (x[,y]*)
802
803Where x[,y]* represents a CSV list of values, without white space. Zero value
804means to use the corresponding memory pool data buffer size.
805
806set txpkts
807~~~~~~~~~~
808
809Set the length of each segment of the TX-ONLY packets or length of packet for FLOWGEN mode::
810
811   testpmd> set txpkts (x[,y]*)
812
813Where x[,y]* represents a CSV list of values, without white space.
814
815set txtimes
816~~~~~~~~~~~
817
818Configure the timing burst pattern for Tx only mode. This command enables
819the packet send scheduling on dynamic timestamp mbuf field and configures
820timing pattern in Tx only mode. In this mode, if scheduling is enabled
821application provides timestamps in the packets being sent. It is possible
822to configure delay (in unspecified device clock units) between bursts
823and between the packets within the burst::
824
825   testpmd> set txtimes (inter),(intra)
826
827where:
828
829* ``inter``  is the delay between the bursts in the device clock units.
830  If ``intra`` is zero, this is the time between the beginnings of the
831  first packets in the neighbour bursts, if ``intra`` is not zero,
832  ``inter`` specifies the time between the beginning of the first packet
833  of the current burst and the beginning of the last packet of the
834  previous burst. If ``inter`` parameter is zero the send scheduling
835  on timestamps is disabled (default).
836
837* ``intra`` is the delay between the packets within the burst specified
838  in the device clock units. The number of packets in the burst is defined
839  by regular burst setting. If ``intra`` parameter is zero no timestamps
840  provided in the packets excepting the first one in the burst.
841
842As the result the bursts of packet will be transmitted with specific
843delays between the packets within the burst and specific delay between
844the bursts. The rte_eth_read_clock() must be supported by the device(s)
845and is supposed to be engaged to get the current device clock value
846and provide the reference for the timestamps. If there is no supported
847rte_eth_read_clock() there will be no send scheduling provided on the port.
848
849set txsplit
850~~~~~~~~~~~
851
852Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes::
853
854   testpmd> set txsplit (off|on|rand)
855
856Where:
857
858* ``off`` disable packet copy & split for CSUM mode.
859
860* ``on`` split outgoing packet into multiple segments. Size of each segment
861  and number of segments per packet is determined by ``set txpkts`` command
862  (see above).
863
864* ``rand`` same as 'on', but number of segments per each packet is a random value between 1 and total number of segments.
865
866set corelist
867~~~~~~~~~~~~
868
869Set the list of forwarding cores::
870
871   testpmd> set corelist (x[,y]*)
872
873For example, to change the forwarding cores:
874
875.. code-block:: console
876
877   testpmd> set corelist 3,1
878   testpmd> show config fwd
879
880   io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled
881   Logical Core 3 (socket 0) forwards packets on 1 streams:
882   RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
883   Logical Core 1 (socket 0) forwards packets on 1 streams:
884   RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
885
886.. note::

888   The cores are used in the same order as specified on the command line.
889
890set portlist
891~~~~~~~~~~~~
892
893Set the list of forwarding ports::
894
895   testpmd> set portlist (x[,y]*)

897For example, to change the port forwarding:
898
899.. code-block:: console
900
901   testpmd> set portlist 0,2,1,3
902   testpmd> show config fwd
903
904   io packet forwarding - ports=4 - cores=1 - streams=4
905   Logical Core 3 (socket 0) forwards packets on 4 streams:
906   RX P=0/Q=0 (socket 0) -> TX P=2/Q=0 (socket 0) peer=02:00:00:00:00:01
907   RX P=2/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
908   RX P=1/Q=0 (socket 0) -> TX P=3/Q=0 (socket 0) peer=02:00:00:00:00:03

1132  as a tunnel packet by the forwarding engine (geneve, gre, gtp, ipip, vxlan and vxlan-gpe are
1133  supported). See also the ``csum parse-tunnel`` command.
1134
1135* ``outer-udp`` relates to the outer UDP layer in the case where the packet is recognized
1136  as a tunnel packet by the forwarding engine (geneve, gtp, vxlan and vxlan-gpe are
1137  supported). See also the ``csum parse-tunnel`` command.
1138
1139.. note::
1140
1141   Check the NIC Datasheet for hardware limits.
1142

1149		queue_start_index (value) queue_num (value)
1150
1151Set flowtype mapping on a RSS queue region on a port::
1152
1153   testpmd> set port (port_id) queue-region region_id (value) flowtype (value)
1154

1166   testpmd> set port (port_id) queue-region flush (on|off)
1167
1168where:
1169
1170* ``on``: is just an enable function which server for other configuration,
1171  it is for all configuration about queue region from up layer,
1172  at first will only keep in DPDK software stored in driver,
1173  only after "flush on", it commit all configuration to HW.
1174
1175* ``"off``: is just clean all configuration about queue region just now,
1176  and restore all to DPDK i40e driver default config when start up.
1177
1178Show all queue region related configuration info on a port::
1179
1180   testpmd> show port (port_id) queue-region
1181
1182.. note::
1183
1184  Queue region only support on PF by now, so these command is
1185  only for configuration of queue region on PF port.
1186
1187csum parse-tunnel
1188~~~~~~~~~~~~~~~~~
1189
1190Define how tunneled packets should be handled by the csum forward
1191engine::
1192
1193   testpmd> csum parse-tunnel (on|off) (tx_port_id)
1194
1195If enabled, the csum forward engine will try to recognize supported
1196tunnel headers (geneve, gtp, gre, ipip, vxlan, vxlan-gpe).
1197
1198If disabled, treat tunnel packets as non-tunneled packets (a inner
1199header is handled as a packet payload).
1200
1201.. note::
1202
1203   The port argument is the TX port like in the ``csum set`` command.
1204
1205Example:
1206
1207Consider a packet in packet like the following::
1208
1209   eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in
1210
1211* If parse-tunnel is enabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
1212  command relate to the inner headers (here ``ipv4_in`` and ``tcp_in``), and the
1213  ``outer-ip|outer-udp`` parameter relates to the outer headers (here ``ipv4_out`` and ``udp_out``).
1214
1215* If parse-tunnel is disabled, the ``ip|udp|tcp|sctp`` parameters of ``csum  set``
1216   command relate to the outer headers, here ``ipv4_out`` and ``udp_out``.

1257set port - gro
1258~~~~~~~~~~~~~~
1259
1260Enable or disable GRO in ``csum`` forwarding engine::
1261
1262   testpmd> set port <port_id> gro on|off
1263
1264If enabled, the csum forwarding engine will perform GRO on the TCP/IPv4
1265packets received from the given port.
1266
1267If disabled, packets received from the given port won't be performed
1268GRO. By default, GRO is disabled for all ports.
1269
1270.. note::
1271
1272   When enable GRO for a port, TCP/IPv4 packets received from the port
1273   will be performed GRO. After GRO, all merged packets have bad
1274   checksums, since the GRO library doesn't re-calculate checksums for
1275   the merged packets. Therefore, if users want the merged packets to
1276   have correct checksums, please select HW IP checksum calculation and
1277   HW TCP checksum calculation for the port which the merged packets are
1278   transmitted to.
1279
1280show port - gro
1281~~~~~~~~~~~~~~~
1282
1283Display GRO configuration for a given port::
1284
1285   testpmd> show port <port_id> gro
1286
1287set gro flush
1288~~~~~~~~~~~~~
1289
1290Set the cycle to flush the GROed packets from reassembly tables::
1291
1292   testpmd> set gro flush <cycles>
1293
1294When enable GRO, the csum forwarding engine performs GRO on received
1295packets, and the GROed packets are stored in reassembly tables. Users
1296can use this command to determine when the GROed packets are flushed
1297from the reassembly tables.
1298
1299The ``cycles`` is measured in GRO operation times. The csum forwarding
1300engine flushes the GROed packets from the tables every ``cycles`` GRO
1301operations.
1302
1303By default, the value of ``cycles`` is 1, which means flush GROed packets
1304from the reassembly tables as soon as one GRO operation finishes. The value
1305of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``.
1306
1307Please note that the large value of ``cycles`` may cause the poor TCP/IP
1308stack performance. Because the GROed packets are delayed to arrive the
1309stack, thus causing more duplicated ACKs and TCP retransmissions.
1310
1311set port - gso
1312~~~~~~~~~~~~~~
1313
1314Toggle per-port GSO support in ``csum`` forwarding engine::
1315
1316   testpmd> set port <port_id> gso on|off
1317
1318If enabled, the csum forwarding engine will perform GSO on supported IPv4
1319packets, transmitted on the given port.
1320
1321If disabled, packets transmitted on the given port will not undergo GSO.
1322By default, GSO is disabled for all ports.
1323
1324.. note::
1325
1326   When GSO is enabled on a port, supported IPv4 packets transmitted on that
1327   port undergo GSO. Afterwards, the segmented packets are represented by
1328   multi-segment mbufs; however, the csum forwarding engine doesn't calculation
1329   of checksums for GSO'd segments in SW. As a result, if users want correct
1330   checksums in GSO segments, they should enable HW checksum calculation for
1331   GSO-enabled ports.
1332
1333   For example, HW checksum calculation for VxLAN GSO'd packets may be enabled
1334   by setting the following options in the csum forwarding engine:
1335
1336   testpmd> csum set outer_ip hw <port_id>
1337
1338   testpmd> csum set ip hw <port_id>
1339
1340   testpmd> csum set tcp hw <port_id>
1341
1342   UDP GSO is the same as IP fragmentation, which treats the UDP header
1343   as the payload and does not modify it during segmentation. That is,
1344   after UDP GSO, only the first output fragment has the original UDP
1345   header. Therefore, users need to enable HW IP checksum calculation
1346   and SW UDP checksum calculation for GSO-enabled ports, if they want
1347   correct checksums for UDP/IPv4 packets.
1348
1349set gso segsz

2002Port Functions
2003--------------
2004
2005The following sections show functions for configuring ports.
2006
2007.. note::
2008
2009   Port configuration changes only become active when forwarding is started/restarted.
2010
2011port attach
2012~~~~~~~~~~~
2013
2014Attach a port specified by pci address or virtual device args::
2015
2016   testpmd> port attach (identifier)
2017
2018To attach a new pci device, the device should be recognized by kernel first.
2019Then it should be moved under DPDK management.
2020Finally the port can be attached to testpmd.
2021
2022For example, to move a pci device using ixgbe under DPDK management:
2023
2024.. code-block:: console
2025
2026   # Check the status of the available devices.
2027   ./usertools/dpdk-devbind.py --status
2028
2029   Network devices using DPDK-compatible driver
2030   ============================================
2031   <none>
2032
2033   Network devices using kernel driver
2034   ===================================
2035   0000:0a:00.0 '82599ES 10-Gigabit' if=eth2 drv=ixgbe unused=
2036
2037
2038   # Bind the device to igb_uio.
2039   sudo ./usertools/dpdk-devbind.py -b igb_uio 0000:0a:00.0
2040
2041
2042   # Recheck the status of the devices.
2043   ./usertools/dpdk-devbind.py --status
2044   Network devices using DPDK-compatible driver
2045   ============================================
2046   0000:0a:00.0 '82599ES 10-Gigabit' drv=igb_uio unused=
2047
2048To attach a port created by virtual device, above steps are not needed.
2049
2050For example, to attach a port whose pci address is 0000:0a:00.0.
2051
2052.. code-block:: console
2053
2054   testpmd> port attach 0000:0a:00.0
2055   Attaching a new port...
2056   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
2057   EAL:   probe driver: 8086:10fb rte_ixgbe_pmd
2058   EAL:   PCI memory mapped at 0x7f83bfa00000
2059   EAL:   PCI memory mapped at 0x7f83bfa80000
2060   PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
2061   PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
2062   Port 0 is attached. Now total ports is 1
2063   Done
2064
2065For example, to attach a port created by pcap PMD.
2066
2067.. code-block:: console
2068
2069   testpmd> port attach net_pcap0
2070   Attaching a new port...
2071   PMD: Initializing pmd_pcap for net_pcap0
2072   PMD: Creating pcap-backed ethdev on numa socket 0
2073   Port 0 is attached. Now total ports is 1
2074   Done
2075
2076In this case, identifier is ``net_pcap0``.
2077This identifier format is the same as ``--vdev`` format of DPDK applications.
2078
2079For example, to re-attach a bonded port which has been previously detached,
2080the mode and slave parameters must be given.
2081
2082.. code-block:: console
2083
2084   testpmd> port attach net_bond_0,mode=0,slave=1
2085   Attaching a new port...
2086   EAL: Initializing pmd_bond for net_bond_0
2087   EAL: Create bonded device net_bond_0 on port 0 in mode 0 on socket 0.
2088   Port 0 is attached. Now total ports is 1
2089   Done
2090
2091
2092port detach
2093~~~~~~~~~~~
2094
2095Detach a specific port::
2096
2097   testpmd> port detach (port_id)
2098
2099Before detaching a port, the port should be stopped and closed.
2100
2101For example, to detach a pci device port 0.
2102
2103.. code-block:: console
2104
2105   testpmd> port stop 0
2106   Stopping ports...
2107   Done
2108   testpmd> port close 0
2109   Closing ports...
2110   Done
2111
2112   testpmd> port detach 0
2113   Detaching a port...
2114   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
2115   EAL:   remove driver: 8086:10fb rte_ixgbe_pmd

2117   EAL:   PCI memory unmapped at 0x7f83bfa80000
2118   Done
2119
2120
2121For example, to detach a virtual device port 0.
2122
2123.. code-block:: console
2124
2125   testpmd> port stop 0
2126   Stopping ports...
2127   Done
2128   testpmd> port close 0
2129   Closing ports...
2130   Done
2131
2132   testpmd> port detach 0
2133   Detaching a port...
2134   PMD: Closing pcap ethdev on numa socket 0
2135   Port 'net_pcap0' is detached. Now total ports is 0
2136   Done
2137
2138To remove a pci device completely from the system, first detach the port from testpmd.
2139Then the device should be moved under kernel management.
2140Finally the device can be removed using kernel pci hotplug functionality.
2141
2142For example, to move a pci device under kernel management:
2143
2144.. code-block:: console
2145
2146   sudo ./usertools/dpdk-devbind.py -b ixgbe 0000:0a:00.0
2147
2148   ./usertools/dpdk-devbind.py --status

2251Set the maximum LRO aggregated packet size::
2252
2253   testpmd> port config all max-lro-pkt-size (value)
2254
2255This is equivalent to the ``--max-lro-pkt-size`` command-line option.
2256
2257port config - Drop Packets
2258~~~~~~~~~~~~~~~~~~~~~~~~~~
2259
2260Enable or disable packet drop on all RX queues of all ports when no receive buffers available::
2261
2262   testpmd> port config all drop-en (on|off)
2263
2264Packet dropping when no receive buffers available is off by default.
2265
2266The ``on`` option is equivalent to the ``--enable-drop-en`` command-line option.
2267
2268port config - RSS
2269~~~~~~~~~~~~~~~~~
2270
2271Set the RSS (Receive Side Scaling) mode on or off::

2274
2275RSS is on by default.
2276
2277The ``all`` option is equivalent to eth|vlan|ip|tcp|udp|sctp|ether|l2tpv3|esp|ah|pfcp.
2278
2279The ``default`` option enables all supported RSS types reported by device info.
2280
2281The ``none`` option is equivalent to the ``--disable-rss`` command-line option.

2296
2297The traffic class should be 4 or 8.
2298
2299port config - Burst
2300~~~~~~~~~~~~~~~~~~~
2301
2302Set the number of packets per burst::
2303
2304   testpmd> port config all burst (value)
2305
2306This is equivalent to the ``--burst`` command-line option.
2307
2308port config - Threshold
2309~~~~~~~~~~~~~~~~~~~~~~~
2310
2311Set thresholds for TX/RX queues::
2312
2313   testpmd> port config all (threshold) (value)
2314
2315Where the threshold type can be:
2316
2317* ``txpt:`` Set the prefetch threshold register of the TX rings, 0 <= value <= 255.
2318
2319* ``txht:`` Set the host threshold register of the TX rings, 0 <= value <= 255.

2394
2395port config dynf
2396~~~~~~~~~~~~~~~~
2397
2398Set/clear dynamic flag per port.
2399testpmd will register this flag in the mbuf (same registration
2400for both Tx and Rx). Then set/clear this flag for each Tx

2425Device Functions
2426----------------
2427
2428The following sections show functions for device operations.
2429
2430device detach
2431~~~~~~~~~~~~~
2432
2433Detach a device specified by pci address or virtual device args::
2434
2435   testpmd> device detach (identifier)
2436
2437Before detaching a device associated with ports, the ports should be stopped and closed.
2438
2439For example, to detach a pci device whose address is 0002:03:00.0.
2440
2441.. code-block:: console
2442
2443    testpmd> device detach 0002:03:00.0
2444    Removing a device...
2445    Port 1 is now closed
2446    EAL: Releasing pci mapped resource for 0002:03:00.0
2447    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218a050000
2448    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218c050000
2449    Device 0002:03:00.0 is detached
2450    Now total ports is 1
2451
2452For example, to detach a port created by pcap PMD.
2453
2454.. code-block:: console
2455
2456    testpmd> device detach net_pcap0
2457    Removing a device...
2458    Port 0 is now closed
2459    Device net_pcap0 is detached
2460    Now total ports is 0
2461    Done
2462
2463In this case, identifier is ``net_pcap0``.
2464This identifier format is the same as ``--vdev`` format of DPDK applications.
2465
2466Link Bonding Functions
2467----------------------
2468
2469The Link Bonding functions make it possible to dynamically create and
2470manage link bonding devices from within testpmd interactive prompt.

2489   testpmd> add bonding slave (slave id) (port id)
2490
2491For example, to add Ethernet device (port 6) to a Link Bonding device (port 10)::
2492
2493   testpmd> add bonding slave 6 10
2494
2495
2496remove bonding slave
2497~~~~~~~~~~~~~~~~~~~~
2498
2499Removes an Ethernet slave device from a Link Bonding device::
2500
2501   testpmd> remove bonding slave (slave id) (port id)
2502
2503For example, to remove Ethernet slave device (port 6) to a Link Bonding device (port 10)::

2547For example, set a Link Bonding device (port 10) to use a balance policy of layer 3+4 (IP addresses & UDP ports)::
2548
2549   testpmd> set bonding balance_xmit_policy 10 l34
2550
2551
2552set bonding mon_period
2553~~~~~~~~~~~~~~~~~~~~~~

2589
2590   testpmd> show bonding config (port id)
2591
2592For example,
2593to show the configuration a Link Bonding device (port 9) with 3 slave devices (1, 3, 4)
2594in balance mode with a transmission policy of layer 2+3::
2595
2596   testpmd> show bonding config 9
2597        Bonding mode: 2
2598        Balance Xmit Policy: BALANCE_XMIT_POLICY_LAYER23

3206Filter Functions
3207----------------
3208
3209This section details the available filter functions that are available.
3210
3211Note these functions interface the deprecated legacy filtering framework,
3212superseded by *rte_flow*. See `Flow rules management`_.
3213
3214.. _testpmd_flow_director:
3215
3216flow_director_mask
3217~~~~~~~~~~~~~~~~~~
3218
3219Set flow director's input masks::
3220
3221   flow_director_mask (port_id) mode IP vlan (vlan_value) \
3222                      src_mask (ipv4_src) (ipv6_src) (src_port) \
3223                      dst_mask (ipv4_dst) (ipv6_dst) (dst_port)
3224
3225   flow_director_mask (port_id) mode MAC-VLAN vlan (vlan_value)
3226
3227   flow_director_mask (port_id) mode Tunnel vlan (vlan_value) \

3229                      tunnel-id (tunnel_id_value)
3230
3231Example, to set flow director mask on port 0::
3232
3233   testpmd> flow_director_mask 0 mode IP vlan 0xefff \
3234            src_mask 255.255.255.255 \

3237                FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF 0xFFFF
3238
3239flow_director_flex_payload
3240~~~~~~~~~~~~~~~~~~~~~~~~~~
3241
3242Configure flexible payload selection::
3243
3244   flow_director_flex_payload (port_id) (raw|l2|l3|l4) (config)

3253
3254Flow rules management
3255---------------------
3256
3257Control of the generic flow API (*rte_flow*) is fully exposed through the
3258``flow`` command (validation, creation, destruction, queries and operation
3259modes).
3260
3261Considering *rte_flow* overlaps with all `Filter Functions`_, using both
3262features simultaneously may cause undefined side-effects and is therefore
3263not recommended.
3264
3265``flow`` syntax
3266~~~~~~~~~~~~~~~
3267
3268Because the ``flow`` command uses dynamic tokens to handle the large number
3269of possible flow rules combinations, its behavior differs slightly from
3270other commands, in particular:
3271
3272- Pressing *?* or the *<tab>* key displays contextual help for the current
3273  token, not that of the entire command.
3274
3275- Optional and repeated parameters are supported (provided they are listed
3276  in the contextual help).
3277
3278The first parameter stands for the operation mode. Possible operations and
3279their general syntax are described below. They are covered in detail in the
3280following sections.
3281
3282- Check whether a flow rule can be created::
3283
3284   flow validate {port_id}
3285       [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3286       pattern {item} [/ {item} [...]] / end
3287       actions {action} [/ {action} [...]] / end
3288

3290
3291   flow create {port_id}
3292       [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3293       pattern {item} [/ {item} [...]] / end
3294       actions {action} [/ {action} [...]] / end
3295
3296- Destroy specific flow rules::
3297
3298   flow destroy {port_id} rule {rule_id} [...]
3299
3300- Destroy all flow rules::
3301
3302   flow flush {port_id}
3303
3304- Query an existing flow rule::
3305
3306   flow query {port_id} {rule_id} {action}
3307
3308- List existing flow rules sorted by priority, filtered by group
3309  identifiers::
3310
3311   flow list {port_id} [group {group_id}] [...]
3312

3320
3321- List and destroy aged flow rules::

3324
3325- Tunnel offload - create a tunnel stub::
3326
3327   flow tunnel create {port_id} type {tunnel_type}
3328
3329- Tunnel offload - destroy a tunnel stub::
3330
3331   flow tunnel destroy {port_id} id {tunnel_id}
3332
3333- Tunnel offload - list port tunnel stubs::
3334
3335   flow tunnel list {port_id}
3336
3337Creating a tunnel stub for offload
3338~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3339
3340``flow tunnel create`` setup a tunnel stub for tunnel offload flow rules::
3341
3342   flow tunnel create {port_id} type {tunnel_type}
3343
3344If successful, it will return a tunnel stub ID usable with other commands::
3345
3346   port [...]: flow tunnel #[...] type [...]
3347
3348Tunnel stub ID is relative to a port.
3349
3350Destroying tunnel offload stub
3351~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3352
3353``flow tunnel destroy`` destroy port tunnel stub::
3354
3355   flow tunnel destroy {port_id} id {tunnel_id}
3356
3357Listing tunnel offload stubs
3358~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3359
3360``flow tunnel list`` list port tunnel offload stubs::
3361
3362   flow tunnel list {port_id}
3363
3364Validating flow rules
3365~~~~~~~~~~~~~~~~~~~~~
3366
3367``flow validate`` reports whether a flow rule would be accepted by the
3368underlying device in its current state but stops short of creating it. It is
3369bound to ``rte_flow_validate()``::
3370
3371   flow validate {port_id}
3372      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3373      pattern {item} [/ {item} [...]] / end
3374      actions {action} [/ {action} [...]] / end
3375
3376If successful, it will show::
3377
3378   Flow rule validated
3379
3380Otherwise it will show an error message of the form::
3381
3382   Caught error type [...] ([...]): [...]
3383
3384This command uses the same parameters as ``flow create``, their format is
3385described in `Creating flow rules`_.
3386
3387Check whether redirecting any Ethernet packet received on port 0 to RX queue
3388index 6 is supported::
3389
3390   testpmd> flow validate 0 ingress pattern eth / end
3391      actions queue index 6 / end
3392   Flow rule validated
3393   testpmd>
3394
3395Port 0 does not support TCPv6 rules::
3396
3397   testpmd> flow validate 0 ingress pattern eth / ipv6 / tcp / end
3398      actions drop / end
3399   Caught error type 9 (specific pattern item): Invalid argument
3400   testpmd>
3401
3402Creating flow rules
3403~~~~~~~~~~~~~~~~~~~
3404
3405``flow create`` validates and creates the specified flow rule. It is bound
3406to ``rte_flow_create()``::
3407
3408   flow create {port_id}
3409      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3410      [tunnel_set {tunnel_id}] [tunnel_match {tunnel_id}]
3411      pattern {item} [/ {item} [...]] / end
3412      actions {action} [/ {action} [...]] / end
3413
3414If successful, it will return a flow rule ID usable with other commands::
3415
3416   Flow rule #[...] created
3417
3418Otherwise it will show an error message of the form::
3419
3420   Caught error type [...] ([...]): [...]
3421
3422Parameters describe in the following order:
3423
3424- Attributes (*group*, *priority*, *ingress*, *egress*, *transfer* tokens).
3425- Tunnel offload specification (tunnel_set, tunnel_match)
3426- A matching pattern, starting with the *pattern* token and terminated by an
3427  *end* pattern item.
3428- Actions, starting with the *actions* token and terminated by an *end*
3429  action.
3430
3431These translate directly to *rte_flow* objects provided as-is to the
3432underlying functions.
3433
3434The shortest valid definition only comprises mandatory tokens::
3435
3436   testpmd> flow create 0 pattern end actions end
3437
3438Note that PMDs may refuse rules that essentially do nothing such as this
3439one.
3440
3441**All unspecified object values are automatically initialized to 0.**
3442
3443Attributes
3444^^^^^^^^^^
3445
3446These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
3447specified before the ``pattern`` token.
3448
3449- ``group {group id}``: priority group.
3450- ``priority {level}``: priority level within group.
3451- ``ingress``: rule applies to ingress traffic.
3452- ``egress``: rule applies to egress traffic.
3453- ``transfer``: apply rule directly to endpoints found in pattern.
3454
3455Each instance of an attribute specified several times overrides the previous
3456value as shown below (group 4 is used)::
3457
3458   testpmd> flow create 0 group 42 group 24 group 4 [...]
3459
3460Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
3461
3462While not specifying a direction is an error, some rules may allow both
3463simultaneously.
3464
3465Most rules affect RX therefore contain the ``ingress`` token::
3466
3467   testpmd> flow create 0 ingress pattern [...]
3468
3469Tunnel offload
3470^^^^^^^^^^^^^^
3471
3472Indicate tunnel offload rule type
3473
3474- ``tunnel_set {tunnel_id}``: mark rule as tunnel offload decap_set type.
3475- ``tunnel_match {tunnel_id}``:  mark rule as tunel offload match type.
3476
3477Matching pattern
3478^^^^^^^^^^^^^^^^
3479
3480A matching pattern starts after the ``pattern`` token. It is made of pattern
3481items and is terminated by a mandatory ``end`` item.
3482
3483Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
3484rte_flow_item_type``).
3485
3486The ``/`` token is used as a separator between pattern items as shown
3487below::
3488
3489   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
3490
3491Note that protocol items like these must be stacked from lowest to highest
3492layer to make sense. For instance, the following rule is either invalid or
3493unlikely to match any packet::
3494
3495   testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
3496
3497More information on these restrictions can be found in the *rte_flow*
3498documentation.
3499
3500Several items support additional specification structures, for example
3501``ipv4`` allows specifying source and destination addresses as follows::
3502
3503   testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
3504      dst is 10.2.0.0 / end [...]
3505
3506This rule matches all IPv4 traffic with the specified properties.
3507
3508In this example, ``src`` and ``dst`` are field names of the underlying
3509``struct rte_flow_item_ipv4`` object. All item properties can be specified
3510in a similar fashion.
3511
3512The ``is`` token means that the subsequent value must be matched exactly,
3513and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
3514accordingly. Possible assignment tokens are:
3515
3516- ``is``: match value perfectly (with full bit-mask).
3517- ``spec``: match value according to configured bit-mask.
3518- ``last``: specify upper bound to establish a range.
3519- ``mask``: specify bit-mask with relevant bits set to one.
3520- ``prefix``: generate bit-mask with <prefix-length> most-significant bits set to one.
3521
3522These yield identical results::
3523
3524   ipv4 src is 10.1.1.1
3525
3526::
3527
3528   ipv4 src spec 10.1.1.1 src mask 255.255.255.255
3529
3530::
3531
3532   ipv4 src spec 10.1.1.1 src prefix 32
3533
3534::
3535
3536   ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
3537
3538::
3539
3540   ipv4 src is 10.1.1.1 src last 0 # 0 disables range
3541
3542Inclusive ranges can be defined with ``last``::
3543
3544   ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
3545
3546Note that ``mask`` affects both ``spec`` and ``last``::
3547
3548   ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0
3549      # matches 10.1.0.0 to 10.2.255.255
3550
3551Properties can be modified multiple times::
3552
3553   ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
3554
3555::
3556
3557   ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16
3558

3761
3762Actions list
3763^^^^^^^^^^^^
3764
3765A list of actions starts after the ``actions`` token in the same fashion as
3766`Matching pattern`_; actions are separated by ``/`` tokens and the list is
3767terminated by a mandatory ``end`` action.
3768
3769Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
3770rte_flow_action_type``).
3771
3772Dropping all incoming UDPv4 packets can be expressed as follows::
3773
3774   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3775      actions drop / end
3776
3777Several actions have configurable properties which must be specified when
3778there is no valid default value. For example, ``queue`` requires a target
3779queue index.
3780
3781This rule redirects incoming UDPv4 traffic to queue index 6::
3782
3783   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3784      actions queue index 6 / end
3785
3786While this one could be rejected by PMDs (unspecified queue index)::
3787
3788   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3789      actions queue / end
3790
3791As defined by *rte_flow*, the list is not ordered, all actions of a given
3792rule are performed simultaneously. These are equivalent::
3793
3794   queue index 6 / void / mark id 42 / end
3795
3796::
3797
3798   void / mark id 42 / queue index 6 / end
3799
3800All actions in a list should have different types, otherwise only the last
3801action of a given type is taken into account::
3802
3803   queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
3804
3805::
3806
3807   drop / drop / drop / end # drop is performed only once
3808
3809::
3810
3811   mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
3812
3813Considering they are performed simultaneously, opposite and overlapping
3814actions can sometimes be combined when the end result is unambiguous::
3815
3816   drop / queue index 6 / end # drop has no effect
3817
3818::
3819
3820   queue index 6 / rss queues 6 7 8 / end # queue has no effect
3821
3822::
3823
3824   drop / passthru / end # drop has no effect
3825
3826Note that PMDs may still refuse such combinations.

4033Destroying flow rules
4034~~~~~~~~~~~~~~~~~~~~~
4035
4036``flow destroy`` destroys one or more rules from their rule ID (as returned
4037by ``flow create``), this command calls ``rte_flow_destroy()`` as many
4038times as necessary::
4039
4040   flow destroy {port_id} rule {rule_id} [...]
4041
4042If successful, it will show::
4043
4044   Flow rule #[...] destroyed
4045
4046It does not report anything for rule IDs that do not exist. The usual error
4047message is shown when a rule cannot be destroyed::
4048
4049   Caught error type [...] ([...]): [...]
4050
4051``flow flush`` destroys all rules on a device and does not take extra
4052arguments. It is bound to ``rte_flow_flush()``::
4053
4054   flow flush {port_id}
4055
4056Any errors are reported as above.
4057
4058Creating several rules and destroying them::
4059
4060   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4061      actions queue index 2 / end
4062   Flow rule #0 created
4063   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4064      actions queue index 3 / end
4065   Flow rule #1 created
4066   testpmd> flow destroy 0 rule 0 rule 1
4067   Flow rule #1 destroyed
4068   Flow rule #0 destroyed
4069   testpmd>
4070
4071The same result can be achieved using ``flow flush``::
4072
4073   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4074      actions queue index 2 / end
4075   Flow rule #0 created
4076   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4077      actions queue index 3 / end
4078   Flow rule #1 created
4079   testpmd> flow flush 0
4080   testpmd>
4081
4082Non-existent rule IDs are ignored::
4083
4084   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4085      actions queue index 2 / end
4086   Flow rule #0 created
4087   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4088      actions queue index 3 / end
4089   Flow rule #1 created
4090   testpmd> flow destroy 0 rule 42 rule 10 rule 2
4091   testpmd>
4092   testpmd> flow destroy 0 rule 0
4093   Flow rule #0 destroyed
4094   testpmd>
4095
4096Querying flow rules
4097~~~~~~~~~~~~~~~~~~~
4098
4099``flow query`` queries a specific action of a flow rule having that
4100ability. Such actions collect information that can be reported using this
4101command. It is bound to ``rte_flow_query()``::
4102
4103   flow query {port_id} {rule_id} {action}
4104
4105If successful, it will display either the retrieved data for known actions
4106or the following message::
4107
4108   Cannot display result for action type [...] ([...])
4109
4110Otherwise, it will complain either that the rule does not exist or that some
4111error occurred::
4112
4113   Flow rule #[...] not found
4114
4115::
4116
4117   Caught error type [...] ([...]): [...]
4118
4119Currently only the ``count`` action is supported. This action reports the
4120number of packets that hit the flow rule and the total number of bytes. Its
4121output has the following format::
4122
4123   count:
4124    hits_set: [...] # whether "hits" contains a valid value
4125    bytes_set: [...] # whether "bytes" contains a valid value
4126    hits: [...] # number of packets
4127    bytes: [...] # number of bytes
4128
4129Querying counters for TCPv6 packets redirected to queue 6::
4130
4131   testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
4132      actions queue index 6 / count / end
4133   Flow rule #4 created
4134   testpmd> flow query 0 4 count
4135   count:
4136    hits_set: 1
4137    bytes_set: 0
4138    hits: 386446
4139    bytes: 0
4140   testpmd>
4141
4142Listing flow rules
4143~~~~~~~~~~~~~~~~~~
4144
4145``flow list`` lists existing flow rules sorted by priority and optionally
4146filtered by group identifiers::
4147
4148   flow list {port_id} [group {group_id}] [...]
4149
4150This command only fails with the following message if the device does not
4151exist::
4152
4153   Invalid port [...]
4154
4155Output consists of a header line followed by a short description of each
4156flow rule, one per line. There is no output at all when no flow rules are
4157configured on the device::
4158
4159   ID      Group   Prio    Attr    Rule
4160   [...]   [...]   [...]   [...]   [...]
4161
4162``Attr`` column flags:
4163
4164- ``i`` for ``ingress``.
4165- ``e`` for ``egress``.
4166
4167Creating several flow rules and listing them::
4168
4169   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4170      actions queue index 6 / end
4171   Flow rule #0 created
4172   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4173      actions queue index 2 / end
4174   Flow rule #1 created
4175   testpmd> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
4176      actions rss queues 6 7 8 end / end
4177   Flow rule #2 created
4178   testpmd> flow list 0
4179   ID      Group   Prio    Attr    Rule
4180   0       0       0       i-      ETH IPV4 => QUEUE
4181   1       0       0       i-      ETH IPV6 => QUEUE
4182   2       0       5       i-      ETH IPV4 UDP => RSS
4183   testpmd>
4184
4185Rules are sorted by priority (i.e. group ID first, then priority level)::
4186
4187   testpmd> flow list 1
4188   ID      Group   Prio    Attr    Rule
4189   0       0       0       i-      ETH => COUNT
4190   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4191   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
4192   1       24      0       i-      ETH IPV4 UDP => QUEUE
4193   4       24      10      i-      ETH IPV4 TCP => DROP
4194   3       24      20      i-      ETH IPV4 => DROP
4195   2       24      42      i-      ETH IPV4 UDP => QUEUE
4196   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
4197   testpmd>
4198
4199Output can be limited to specific groups::
4200
4201   testpmd> flow list 1 group 0 group 63
4202   ID      Group   Prio    Attr    Rule
4203   0       0       0       i-      ETH => COUNT
4204   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4205   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
4206   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
4207   testpmd>
4208
4209Toggling isolated mode
4210~~~~~~~~~~~~~~~~~~~~~~
4211
4212``flow isolate`` can be used to tell the underlying PMD that ingress traffic
4213must only be injected from the defined flow rules; that no default traffic
4214is expected outside those rules and the driver is free to assign more
4215resources to handle them. It is bound to ``rte_flow_isolate()``::
4216
4217 flow isolate {port_id} {boolean}
4218
4219If successful, enabling or disabling isolated mode shows either::
4220
4221 Ingress traffic on port [...]
4222    is now restricted to the defined flow rules
4223
4224Or::
4225
4226 Ingress traffic on port [...]
4227    is not restricted anymore to the defined flow rules
4228
4229Otherwise, in case of error::
4230
4231   Caught error type [...] ([...]): [...]
4232
4233Mainly due to its side effects, PMDs supporting this mode may not have the
4234ability to toggle it more than once without reinitializing affected ports
4235first (e.g. by exiting testpmd).
4236
4237Enabling isolated mode::
4238
4239 testpmd> flow isolate 0 true
4240 Ingress traffic on port 0 is now restricted to the defined flow rules
4241 testpmd>
4242
4243Disabling isolated mode::
4244
4245 testpmd> flow isolate 0 false
4246 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
4247 testpmd>
4248
4249Dumping HW internal information
4250~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4251
4252``flow dump`` dumps the hardware's internal representation information of
4253all flows. It is bound to ``rte_flow_dev_dump()``::
4254
4255   flow dump {port_id} {output_file}
4256
4257If successful, it will show::
4258
4259   Flow dump finished
4260
4261Otherwise, it will complain error occurred::
4262
4263   Caught error type [...] ([...]): [...]
4264
4265Listing and destroying aged flow rules
4266~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4267
4268``flow aged`` simply lists aged flow rules be get from api ``rte_flow_get_aged_flows``,
4269and ``destroy`` parameter can be used to destroy those flow rules in PMD.
4270
4271   flow aged {port_id} [destroy]
4272
4273Listing current aged flow rules::
4274
4275   testpmd> flow aged 0
4276   Port 0 total aged flows: 0
4277   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.14 / end
4278      actions age timeout 5 / queue index 0 /  end
4279   Flow rule #0 created
4280   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.15 / end
4281      actions age timeout 4 / queue index 0 /  end
4282   Flow rule #1 created
4283   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.16 / end
4284      actions age timeout 2 / queue index 0 /  end
4285   Flow rule #2 created
4286   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.17 / end
4287      actions age timeout 3 / queue index 0 /  end
4288   Flow rule #3 created
4289
4290
4291Aged Rules are simply list as command ``flow list {port_id}``, but strip the detail rule
4292information, all the aged flows are sorted by the longest timeout time. For example, if
4293those rules be configured in the same time, ID 2 will be the first aged out rule, the next
4294will be ID 3, ID 1, ID 0::
4295
4296   testpmd> flow aged 0
4297   Port 0 total aged flows: 4
4298   ID      Group   Prio    Attr
4299   2       0       0       i--
4300   3       0       0       i--
4301   1       0       0       i--
4302   0       0       0       i--
4303
4304If attach ``destroy`` parameter, the command will destroy all the list aged flow rules.
4305
4306   testpmd> flow aged 0 destroy
4307   Port 0 total aged flows: 4
4308   ID      Group   Prio    Attr
4309   2       0       0       i--
4310   3       0       0       i--
4311   1       0       0       i--
4312   0       0       0       i--
4313
4314   Flow rule #2 destroyed
4315   Flow rule #3 destroyed
4316   Flow rule #1 destroyed
4317   Flow rule #0 destroyed

4322Creating shared actions
4323~~~~~~~~~~~~~~~~~~~~~~~
4324``flow shared_action {port_id} create`` creates shared action with optional
4325shared action ID. It is bound to ``rte_flow_shared_action_create()``::
4326
4327   flow shared_action {port_id} create [action_id {shared_action_id}]
4328      [ingress] [egress] action {action} / end
4329
4330If successful, it will show::
4331
4332   Shared action #[...] created
4333
4334Otherwise, it will complain either that shared action already exists or that
4335some error occurred::
4336
4337   Shared action #[...] is already assigned, delete it first
4338
4339::
4340
4341   Caught error type [...] ([...]): [...]
4342
4343Create shared rss action with id 100 to queues 1 and 2 on port 0::
4344
4345   testpmd> flow shared_action 0 create action_id 100 \
4346      ingress action rss queues 1 2 end / end
4347
4348Create shared rss action with id assigned by testpmd to queues 1 and 2 on
4349port 0::
4350
4351	testpmd> flow shared_action 0 create action_id \
4352		ingress action rss queues 0 1 end / end
4353
4354Updating shared actions
4355~~~~~~~~~~~~~~~~~~~~~~~
4356``flow shared_action {port_id} update`` updates configuration of the shared
4357action from its shared action ID (as returned by
4358``flow shared_action {port_id} create``). It is bound to
4359``rte_flow_shared_action_update()``::
4360
4361   flow shared_action {port_id} update {shared_action_id}
4362      action {action} / end
4363
4364If successful, it will show::
4365
4366   Shared action #[...] updated
4367
4368Otherwise, it will complain either that shared action not found or that some
4369error occurred::
4370
4371   Failed to find shared action #[...] on port [...]
4372
4373::
4374
4375   Caught error type [...] ([...]): [...]
4376
4377Update shared rss action having id 100 on port 0 with rss to queues 0 and 3
4378(in create example above rss queues were 1 and 2)::
4379
4380   testpmd> flow shared_action 0 update 100 action rss queues 0 3 end / end
4381
4382Destroying shared actions
4383~~~~~~~~~~~~~~~~~~~~~~~~~
4384``flow shared_action {port_id} update`` destroys one or more shared actions
4385from their shared action IDs (as returned by
4386``flow shared_action {port_id} create``). It is bound to
4387``rte_flow_shared_action_destroy()``::
4388
4389   flow shared_action {port_id} destroy action_id {shared_action_id} [...]
4390
4391If successful, it will show::
4392
4393   Shared action #[...] destroyed
4394
4395It does not report anything for shared action IDs that do not exist.
4396The usual error message is shown when a shared action cannot be destroyed::
4397
4398   Caught error type [...] ([...]): [...]
4399
4400Destroy shared actions having id 100 & 101::
4401
4402   testpmd> flow shared_action 0 destroy action_id 100 action_id 101
4403
4404Query shared actions
4405~~~~~~~~~~~~~~~~~~~~
4406``flow shared_action {port_id} query`` queries the shared action from its
4407shared action ID (as returned by ``flow shared_action {port_id} create``).
4408It is bound to ``rte_flow_shared_action_query()``::
4409
4410  flow shared_action {port_id} query {shared_action_id}
4411
4412Currently only rss shared action supported. If successful, it will show::
4413
4414   Shared RSS action:
4415      refs:[...]
4416
4417Otherwise, it will complain either that shared action not found or that some
4418error occurred::
4419
4420   Failed to find shared action #[...] on port [...]
4421
4422::
4423
4424   Caught error type [...] ([...]): [...]
4425
4426Query shared action having id 100::
4427
4428   testpmd> flow shared_action 0 query 100
4429
4430Sample QinQ flow rules
4431~~~~~~~~~~~~~~~~~~~~~~
4432
4433Before creating QinQ rule(s) the following commands should be issued to enable QinQ::
4434
4435   testpmd> port stop 0
4436   testpmd> vlan set qinq_strip on 0
4437
4438The above command sets the inner and outer TPID's to 0x8100.
4439
4440To change the TPID's the following commands should be used::
4441
4442   testpmd> vlan set outer tpid 0xa100 0
4443   testpmd> vlan set inner tpid 0x9100 0
4444   testpmd> port start 0
4445
4446Validate and create a QinQ rule on port 0 to steer traffic to a VF queue in a VM.
4447
4448::
4449
4450   testpmd> flow validate 0 ingress pattern eth / vlan tci is 123 /
4451       vlan tci is 456 / end actions vf id 1 / queue index 0 / end
4452   Flow rule #0 validated

4461
4462Validate and create a QinQ rule on port 0 to steer traffic to a queue on the host.
4463
4464::
4465
4466   testpmd> flow validate 0 ingress pattern eth / vlan tci is 321 /
4467        vlan tci is 654 / end actions pf / queue index 0 / end

4479Sample VXLAN flow rules
4480~~~~~~~~~~~~~~~~~~~~~~~
4481
4482Before creating VXLAN rule(s), the UDP port should be added for VXLAN packet
4483filter on a port::
4484
4485  testpmd> rx_vxlan_port add 4789 0
4486
4487Create VXLAN rules on port 0 to steer traffic to PF queues.

4838BPF Functions
4839--------------
4840
4841The following sections show functions to load/unload eBPF based filters.
4842
4843bpf-load
4844~~~~~~~~
4845
4846Load an eBPF program as a callback for particular RX/TX queue::
4847
4848   testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)
4849
4850The available load-flags are:
4851
4852* ``J``: use JIT generated native code, otherwise BPF interpreter will be used.
4853
4854* ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.
4855
4856* ``-``: none.
4857
4858.. note::
4859
4860   You'll need clang v3.7 or above to build bpf program you'd like to load
4861
4862For example:
4863
4864.. code-block:: console
4865
4866   cd examples/bpf
4867   clang -O2 -target bpf -c t1.c
4868
4869Then to load (and JIT compile) t1.o at RX queue 0, port 1:
4870
4871.. code-block:: console
4872
4873   testpmd> bpf-load rx 1 0 J ./dpdk.org/examples/bpf/t1.o
4874
4875To load (not JITed) t1.o at TX queue 0, port 0:
4876
4877.. code-block:: console
4878
4879   testpmd> bpf-load tx 0 0 - ./dpdk.org/examples/bpf/t1.o
4880
4881bpf-unload
4882~~~~~~~~~~
4883
4884Unload previously loaded eBPF program for particular RX/TX queue::
4885
4886   testpmd> bpf-unload rx|tx (portid) (queueid)
4887
4888For example to unload BPF filter from TX queue 0, port 0:
4889
4890.. code-block:: console
4891
4892   testpmd> bpf-unload tx 0 0
4893
