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|dcb_tc|cap X
28       info [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|dcb_tc|cap all
29       stats [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|dcb_tc|cap X
30       stats [Mul-choice STRING]: show|clear port info|stats|xstats|fdir|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       Help is available for the following sections:
53
54           help control                    : Start and stop forwarding.
55           help display                    : Displaying port, stats and config information.
56           help config                     : Configuration information.
57           help ports                      : Configuring ports.

64Command File Functions
65----------------------
66
67To facilitate loading large number of commands or to avoid cutting and pasting where not
68practical or possible testpmd supports alternative methods for executing commands.
69
70* If started with the ``--cmdline-file=FILENAME`` command line argument testpmd
71  will execute all CLI commands contained within the file immediately before
72  starting packet forwarding or entering interactive mode.
73
74.. code-block:: console
75
76   ./dpdk-testpmd -n4 -r2 ... -- -i --cmdline-file=/home/ubuntu/flow-create-commands.txt

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

109   Read all CLI commands from /home/ubuntu/flow-create-commands.txt
110   testpmd>
111
112
113In all cases output from any included command will be displayed as standard output.
114Execution will continue until the end of the file is reached regardless of
115whether any errors occur.  The end user must examine the output to determine if
116any failures occurred.

308   nb forwarding cores=2 - nb forwarding ports=1
309   RX queues=1 - RX desc=128 - RX free threshold=0
310   RX threshold registers: pthresh=8 hthresh=8 wthresh=4
311   TX queues=1 - TX desc=512 - TX free threshold=0
312   TX threshold registers: pthresh=36 hthresh=0 wthresh=0
313   TX RS bit threshold=0 - TXQ flags=0x0
314
315set fwd
316~~~~~~~
317
318Set the packet forwarding mode::
319
320   testpmd> set fwd (io|mac|macswap|flowgen| \
321                     rxonly|txonly|csum|icmpecho|noisy|5tswap|shared-rxq) (""|retry)
322
323``retry`` can be specified for forwarding engines except ``rx_only``.
324
325The available information categories are:
326
327* ``io``: Forwards packets "as-is" in I/O mode.
328  This is the fastest possible forwarding operation as it does not access packets data.
329  This is the default mode.
330
331* ``mac``: Changes the source and the destination Ethernet addresses of packets before forwarding them.
332  Default application behavior is to set source Ethernet address to that of the transmitting interface, and destination
333  address to a dummy value (set during init). The user may specify a target destination Ethernet address via the 'eth-peer' or
334  'eth-peers-configfile' command-line options. It is not currently possible to specify a specific source Ethernet address.
335
336* ``macswap``: MAC swap forwarding mode.
337  Swaps the source and the destination Ethernet addresses of packets before forwarding them.
338
339* ``flowgen``: Multi-flow generation mode.
340  Originates a number of flows (with varying destination IP addresses), and terminate receive traffic.
341
342* ``rxonly``: Receives packets but doesn't transmit them.
343
344* ``txonly``: Generates and transmits packets without receiving any.
345
346* ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet.
347
348* ``icmpecho``: Receives a burst of packets, lookup for ICMP echo requests and, if any, send back ICMP echo replies.
349
350* ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX.
351
352* ``noisy``: Noisy neighbor simulation.
353  Simulate more realistic behavior of a guest machine engaged in receiving
354  and sending packets performing Virtual Network Function (VNF).
355
356* ``5tswap``: Swap the source and destination of L2,L3,L4 if they exist.
357
358  L2 swaps the source address and destination address of Ethernet, as same as ``macswap``.
359
360  L3 swaps the source address and destination address of IP (v4 and v6).
361
362  L4 swaps the source port and destination port of transport layer (TCP and UDP).
363
364* ``shared-rxq``: Receive only for shared Rx queue.
365  Resolve packet source port from mbuf and update stream statistics accordingly.
366
367Example::
368
369   testpmd> set fwd rxonly
370
371   Set rxonly packet forwarding mode
372
373
374show fwd
375~~~~~~~~
376
377When running, forwarding engines maintain statistics from the time they have been started.
378Example for the io forwarding engine, with some packet drops on the tx side::
379
380   testpmd> show fwd stats all

634Configuration Functions
635-----------------------
636
637The testpmd application can be configured from the runtime as well as from the command-line.
638
639This section details the available configuration functions that are available.
640
641.. note::
642
643   Configuration changes only become active when forwarding is started/restarted.
644
645set default
646~~~~~~~~~~~
647
648Reset forwarding to the default configuration::
649
650   testpmd> set default
651
652set verbose
653~~~~~~~~~~~
654
655Set the debug verbosity level::
656
657   testpmd> set verbose (level)
658
659Available levels are as following:
660
661* ``0`` silent except for error.
662* ``1`` fully verbose except for Tx packets.
663* ``2`` fully verbose except for Rx packets.
664* ``> 2`` fully verbose.
665
666set log
667~~~~~~~
668
669Set the log level for a log type::
670
671	testpmd> set log global|(type) (level)
672
673Where:
674
675* ``type`` is the log name.
676
677* ``level`` is the log level.
678
679For example, to change the global log level::
680
681	testpmd> set log global (level)
682
683Regexes can also be used for type. To change log level of user1, user2 and user3::
684
685	testpmd> set log user[1-3] (level)
686
687set nbport
688~~~~~~~~~~
689
690Set the number of ports used by the application:
691
692set nbport (num)
693
694This is equivalent to the ``--nb-ports`` command-line option.
695
696set nbcore
697~~~~~~~~~~
698
699Set the number of cores used by the application::
700
701   testpmd> set nbcore (num)
702
703This is equivalent to the ``--nb-cores`` command-line option.
704
705.. note::
706
707   The number of cores used must not be greater than number of ports used multiplied by the number of queues per port.
708
709set coremask
710~~~~~~~~~~~~
711
712Set the forwarding cores hexadecimal mask::
713
714   testpmd> set coremask (mask)
715
716This is equivalent to the ``--coremask`` command-line option.
717
718.. note::
719
720   The main lcore is reserved for command line parsing only and cannot be masked on for packet forwarding.
721
722set portmask
723~~~~~~~~~~~~
724
725Set the forwarding ports hexadecimal mask::
726
727   testpmd> set portmask (mask)
728
729This is equivalent to the ``--portmask`` command-line option.
730
731set record-core-cycles
732~~~~~~~~~~~~~~~~~~~~~~
733
734Set the recording of CPU cycles::
735
736   testpmd> set record-core-cycles (on|off)
737
738Where:
739
740* ``on`` enables measurement of CPU cycles per packet.
741
742* ``off`` disables measurement of CPU cycles per packet.
743
744This is equivalent to the ``--record-core-cycles command-line`` option.
745
746set record-burst-stats
747~~~~~~~~~~~~~~~~~~~~~~
748
749Set the displaying of RX and TX bursts::
750
751   testpmd> set record-burst-stats (on|off)
752
753Where:
754
755* ``on`` enables display of RX and TX bursts.
756
757* ``off`` disables display of RX and TX bursts.
758
759This is equivalent to the ``--record-burst-stats command-line`` option.
760
761set burst
762~~~~~~~~~
763
764Set number of packets per burst::
765
766   testpmd> set burst (num)
767
768This is equivalent to the ``--burst command-line`` option.
769
770When retry is enabled, the transmit delay time and number of retries can also be set::
771
772   testpmd> set burst tx delay (microseconds) retry (num)
773
774set rxoffs
775~~~~~~~~~~
776
777Set the offsets of segments relating to the data buffer beginning on receiving
778if split feature is engaged. Affects only the queues configured with split
779offloads (currently BUFFER_SPLIT is supported only).
780
781   testpmd> set rxoffs (x[,y]*)
782
783Where x[,y]* represents a CSV list of values, without white space. If the list
784of offsets is shorter than the list of segments the zero offsets will be used
785for the remaining segments.
786
787set rxpkts
788~~~~~~~~~~
789
790Set the length of segments to scatter packets on receiving if split
791feature is engaged. Affects only the queues configured with split offloads
792(currently BUFFER_SPLIT is supported only). Optionally the multiple memory
793pools can be specified with --mbuf-size command line parameter and the mbufs
794to receive will be allocated sequentially from these extra memory pools (the
795mbuf for the first segment is allocated from the first pool, the second one
796from the second pool, and so on, if segment number is greater then pool's the
797mbuf for remaining segments will be allocated from the last valid pool).
798
799   testpmd> set rxpkts (x[,y]*)
800
801Where x[,y]* represents a CSV list of values, without white space. Zero value
802means to use the corresponding memory pool data buffer size.
803
804set rxhdrs
805~~~~~~~~~~
806
807Set the protocol headers of segments to scatter packets on receiving
808if split feature is engaged.
809Affects only the queues configured with split offloads
810(currently BUFFER_SPLIT is supported only).
811
812   testpmd> set rxhdrs (eth[,ipv4]*)
813
814Where eth[,ipv4]* represents a CSV list of values, without white space.
815If the list of offsets is shorter than the list of segments,
816zero offsets will be used for the remaining segments.
817
818set txpkts
819~~~~~~~~~~
820
821Set the length of each segment of the TX-ONLY packets or length of packet for FLOWGEN mode::
822
823   testpmd> set txpkts (x[,y]*)
824
825Where x[,y]* represents a CSV list of values, without white space.
826
827set txtimes
828~~~~~~~~~~~
829
830Configure the timing burst pattern for Tx only mode. This command enables
831the packet send scheduling on dynamic timestamp mbuf field and configures
832timing pattern in Tx only mode. In this mode, if scheduling is enabled
833application provides timestamps in the packets being sent. It is possible
834to configure delay (in unspecified device clock units) between bursts
835and between the packets within the burst::
836
837   testpmd> set txtimes (inter),(intra)
838
839where:
840
841* ``inter``  is the delay between the bursts in the device clock units.
842  If ``intra`` is zero, this is the time between the beginnings of the
843  first packets in the neighbour bursts, if ``intra`` is not zero,
844  ``inter`` specifies the time between the beginning of the first packet
845  of the current burst and the beginning of the last packet of the
846  previous burst. If ``inter`` parameter is zero the send scheduling
847  on timestamps is disabled (default).
848
849* ``intra`` is the delay between the packets within the burst specified
850  in the device clock units. The number of packets in the burst is defined
851  by regular burst setting. If ``intra`` parameter is zero no timestamps
852  provided in the packets excepting the first one in the burst.
853
854As the result the bursts of packet will be transmitted with specific
855delays between the packets within the burst and specific delay between
856the bursts. The rte_eth_read_clock() must be supported by the device(s)
857and is supposed to be engaged to get the current device clock value
858and provide the reference for the timestamps. If there is no supported
859rte_eth_read_clock() there will be no send scheduling provided on the port.
860
861set txsplit
862~~~~~~~~~~~
863
864Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes::
865
866   testpmd> set txsplit (off|on|rand)
867
868Where:
869
870* ``off`` disable packet copy & split for CSUM mode.
871
872* ``on`` split outgoing packet into multiple segments. Size of each segment
873  and number of segments per packet is determined by ``set txpkts`` command
874  (see above).
875
876* ``rand`` same as 'on', but number of segments per each packet is a random value between 1 and total number of segments.
877
878set corelist
879~~~~~~~~~~~~
880
881Set the list of forwarding cores::
882
883   testpmd> set corelist (x[,y]*)
884
885For example, to change the forwarding cores:
886
887.. code-block:: console
888
889   testpmd> set corelist 3,1
890   testpmd> show config fwd
891
892   io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled
893   Logical Core 3 (socket 0) forwards packets on 1 streams:
894   RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
895   Logical Core 1 (socket 0) forwards packets on 1 streams:
896   RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
897
898.. note::

912
913   testpmd> set portlist 0,2,1,3
914   testpmd> show config fwd
915
916   io packet forwarding - ports=4 - cores=1 - streams=4
917   Logical Core 3 (socket 0) forwards packets on 4 streams:
918   RX P=0/Q=0 (socket 0) -> TX P=2/Q=0 (socket 0) peer=02:00:00:00:00:01
919   RX P=2/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
920   RX P=1/Q=0 (socket 0) -> TX P=3/Q=0 (socket 0) peer=02:00:00:00:00:03
921   RX P=3/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:02

1078csum set
1079~~~~~~~~
1080
1081Select hardware or software calculation of the checksum when
1082transmitting a packet using the ``csum`` forwarding engine::
1083
1084   testpmd> csum set (ip|udp|tcp|sctp|outer-ip|outer-udp) (hw|sw) (port_id)
1085
1086Where:
1087
1088* ``ip|udp|tcp|sctp`` always relate to  the inner layer.
1089
1090* ``outer-ip`` relates to the outer IP layer (only for IPv4) in the case where the packet is recognized
1091  as a tunnel packet by the forwarding engine (geneve, gre, gtp, ipip, vxlan and vxlan-gpe are
1092  supported). See also the ``csum parse-tunnel`` command.
1093
1094* ``outer-udp`` relates to the outer UDP layer in the case where the packet is recognized
1095  as a tunnel packet by the forwarding engine (geneve, gtp, vxlan and vxlan-gpe are
1096  supported). See also the ``csum parse-tunnel`` command.
1097
1098.. note::
1099
1100   Check the NIC Datasheet for hardware limits.
1101
1102csum parse-tunnel
1103~~~~~~~~~~~~~~~~~
1104
1105Define how tunneled packets should be handled by the csum forward
1106engine::
1107
1108   testpmd> csum parse-tunnel (on|off) (tx_port_id)
1109
1110If enabled, the csum forward engine will try to recognize supported
1111tunnel headers (geneve, gtp, gre, ipip, vxlan, vxlan-gpe).
1112
1113If disabled, treat tunnel packets as non-tunneled packets (a inner
1114header is handled as a packet payload).
1115
1116.. note::
1117
1118   The port argument is the TX port like in the ``csum set`` command.
1119
1120Example:
1121
1122Consider a packet in packet like the following::
1123
1124   eth_out/ipv4_out/udp_out/vxlan/eth_in/ipv4_in/tcp_in
1125
1126* If parse-tunnel is enabled, the ``ip|udp|tcp|sctp`` parameters of ``csum set``
1127  command relate to the inner headers (here ``ipv4_in`` and ``tcp_in``), and the
1128  ``outer-ip|outer-udp`` parameter relates to the outer headers (here ``ipv4_out`` and ``udp_out``).
1129
1130* If parse-tunnel is disabled, the ``ip|udp|tcp|sctp`` parameters of ``csum  set``
1131   command relate to the outer headers, here ``ipv4_out`` and ``udp_out``.
1132
1133csum show

1139
1140tso set
1141~~~~~~~
1142
1143Enable TCP Segmentation Offload (TSO) in the ``csum`` forwarding engine::
1144
1145   testpmd> tso set (segsize) (port_id)
1146
1147.. note::
1148
1149   Check the NIC datasheet for hardware limits.
1150
1151tso show
1152~~~~~~~~
1153

1155
1156   testpmd> tso show (port_id)
1157
1158tunnel tso set
1159~~~~~~~~~~~~~~
1160
1161Set tso segment size of tunneled packets for a port in csum engine::
1162
1163   testpmd> tunnel_tso set (tso_segsz) (port_id)
1164
1165tunnel tso show
1166~~~~~~~~~~~~~~~
1167

1169
1170   testpmd> tunnel_tso show (port_id)
1171
1172set port - gro
1173~~~~~~~~~~~~~~
1174
1175Enable or disable GRO in ``csum`` forwarding engine::
1176
1177   testpmd> set port <port_id> gro on|off
1178
1179If enabled, the csum forwarding engine will perform GRO on the TCP/IPv4
1180packets received from the given port.
1181
1182If disabled, packets received from the given port won't be performed
1183GRO. By default, GRO is disabled for all ports.
1184
1185.. note::
1186
1187   When enable GRO for a port, TCP/IPv4 packets received from the port
1188   will be performed GRO. After GRO, all merged packets have bad
1189   checksums, since the GRO library doesn't re-calculate checksums for
1190   the merged packets. Therefore, if users want the merged packets to
1191   have correct checksums, please select HW IP checksum calculation and
1192   HW TCP checksum calculation for the port which the merged packets are
1193   transmitted to.
1194
1195show port - gro
1196~~~~~~~~~~~~~~~
1197
1198Display GRO configuration for a given port::
1199
1200   testpmd> show port <port_id> gro
1201
1202set gro flush
1203~~~~~~~~~~~~~
1204
1205Set the cycle to flush the GROed packets from reassembly tables::
1206
1207   testpmd> set gro flush <cycles>
1208
1209When enable GRO, the csum forwarding engine performs GRO on received
1210packets, and the GROed packets are stored in reassembly tables. Users
1211can use this command to determine when the GROed packets are flushed
1212from the reassembly tables.
1213
1214The ``cycles`` is measured in GRO operation times. The csum forwarding
1215engine flushes the GROed packets from the tables every ``cycles`` GRO
1216operations.
1217
1218By default, the value of ``cycles`` is 1, which means flush GROed packets
1219from the reassembly tables as soon as one GRO operation finishes. The value
1220of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``.
1221
1222Please note that the large value of ``cycles`` may cause the poor TCP/IP
1223stack performance. Because the GROed packets are delayed to arrive the
1224stack, thus causing more duplicated ACKs and TCP retransmissions.
1225
1226set port - gso
1227~~~~~~~~~~~~~~
1228
1229Toggle per-port GSO support in ``csum`` forwarding engine::
1230
1231   testpmd> set port <port_id> gso on|off
1232
1233If enabled, the csum forwarding engine will perform GSO on supported IPv4
1234packets, transmitted on the given port.
1235
1236If disabled, packets transmitted on the given port will not undergo GSO.
1237By default, GSO is disabled for all ports.
1238
1239.. note::
1240
1241   When GSO is enabled on a port, supported IPv4 packets transmitted on that
1242   port undergo GSO. Afterwards, the segmented packets are represented by
1243   multi-segment mbufs; however, the csum forwarding engine doesn't calculation
1244   of checksums for GSO'd segments in SW. As a result, if users want correct
1245   checksums in GSO segments, they should enable HW checksum calculation for
1246   GSO-enabled ports.
1247
1248   For example, HW checksum calculation for VxLAN GSO'd packets may be enabled
1249   by setting the following options in the csum forwarding engine:
1250
1251   testpmd> csum set outer_ip hw <port_id>
1252
1253   testpmd> csum set ip hw <port_id>
1254
1255   testpmd> csum set tcp hw <port_id>
1256
1257   UDP GSO is the same as IP fragmentation, which treats the UDP header
1258   as the payload and does not modify it during segmentation. That is,
1259   after UDP GSO, only the first output fragment has the original UDP
1260   header. Therefore, users need to enable HW IP checksum calculation
1261   and SW UDP checksum calculation for GSO-enabled ports, if they want
1262   correct checksums for UDP/IPv4 packets.
1263
1264set gso segsz
1265~~~~~~~~~~~~~
1266
1267Set the maximum GSO segment size (measured in bytes), which includes the

1730
1731Config Raw Encapsulation
1732~~~~~~~~~~~~~~~~~~~~~~~~~
1733
1734Configure the raw data to be used when encapsulating a packet by
1735rte_flow_action_raw_encap::
1736
1737 set raw_encap {index} {item} [/ {item} [...]] / end_set
1738
1739There are multiple global buffers for ``raw_encap``, this command will set one
1740internal buffer index by ``{index}``.
1741If there is no ``{index}`` specified::
1742
1743 set raw_encap {item} [/ {item} [...]] / end_set
1744
1745the default index ``0`` is used.
1746In order to use different encapsulating header, ``index`` must be specified
1747during the flow rule creation::
1748
1749 testpmd> flow create 0 egress pattern eth / ipv4 / end actions
1750        raw_encap index 2 / end
1751
1752Otherwise the default index ``0`` is used.

1803Port Functions
1804--------------
1805
1806The following sections show functions for configuring ports.
1807
1808.. note::
1809
1810   Port configuration changes only become active when forwarding is started/restarted.
1811
1812.. _port_attach:
1813
1814port attach
1815~~~~~~~~~~~
1816
1817Attach a port specified by pci address or virtual device args::
1818
1819   testpmd> port attach (identifier)
1820
1821To attach a new pci device, the device should be recognized by kernel first.
1822Then it should be moved under DPDK management.
1823Finally the port can be attached to testpmd.
1824
1825For example, to move a pci device using ixgbe under DPDK management:
1826
1827.. code-block:: console
1828
1829   # Check the status of the available devices.
1830   ./usertools/dpdk-devbind.py --status
1831
1832   Network devices using DPDK-compatible driver
1833   ============================================
1834   <none>
1835
1836   Network devices using kernel driver
1837   ===================================
1838   0000:0a:00.0 '82599ES 10-Gigabit' if=eth2 drv=ixgbe unused=
1839
1840
1841   # Bind the device to igb_uio.
1842   sudo ./usertools/dpdk-devbind.py -b igb_uio 0000:0a:00.0
1843
1844
1845   # Recheck the status of the devices.
1846   ./usertools/dpdk-devbind.py --status
1847   Network devices using DPDK-compatible driver
1848   ============================================
1849   0000:0a:00.0 '82599ES 10-Gigabit' drv=igb_uio unused=
1850
1851To attach a port created by virtual device, above steps are not needed.
1852
1853For example, to attach a port whose pci address is 0000:0a:00.0.
1854
1855.. code-block:: console
1856
1857   testpmd> port attach 0000:0a:00.0
1858   Attaching a new port...
1859   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
1860   EAL:   probe driver: 8086:10fb rte_ixgbe_pmd
1861   EAL:   PCI memory mapped at 0x7f83bfa00000
1862   EAL:   PCI memory mapped at 0x7f83bfa80000
1863   PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 18, SFP+: 5
1864   PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb
1865   Port 0 is attached. Now total ports is 1
1866   Done
1867
1868For example, to attach a port created by pcap PMD.
1869
1870.. code-block:: console
1871
1872   testpmd> port attach net_pcap0
1873   Attaching a new port...
1874   PMD: Initializing pmd_pcap for net_pcap0
1875   PMD: Creating pcap-backed ethdev on numa socket 0
1876   Port 0 is attached. Now total ports is 1
1877   Done
1878
1879In this case, identifier is ``net_pcap0``.
1880This identifier format is the same as ``--vdev`` format of DPDK applications.
1881
1882For example, to re-attach a bonded port which has been previously detached,
1883the mode and slave parameters must be given.
1884
1885.. code-block:: console
1886
1887   testpmd> port attach net_bond_0,mode=0,slave=1
1888   Attaching a new port...
1889   EAL: Initializing pmd_bond for net_bond_0
1890   EAL: Create bonded device net_bond_0 on port 0 in mode 0 on socket 0.
1891   Port 0 is attached. Now total ports is 1
1892   Done
1893
1894
1895port detach
1896~~~~~~~~~~~
1897
1898Detach a specific port::
1899
1900   testpmd> port detach (port_id)
1901
1902Before detaching a port, the port should be stopped and closed.
1903
1904For example, to detach a pci device port 0.
1905
1906.. code-block:: console
1907
1908   testpmd> port stop 0
1909   Stopping ports...
1910   Done
1911   testpmd> port close 0
1912   Closing ports...
1913   Done
1914
1915   testpmd> port detach 0
1916   Detaching a port...
1917   EAL: PCI device 0000:0a:00.0 on NUMA socket -1
1918   EAL:   remove driver: 8086:10fb rte_ixgbe_pmd
1919   EAL:   PCI memory unmapped at 0x7f83bfa00000
1920   EAL:   PCI memory unmapped at 0x7f83bfa80000
1921   Done
1922
1923
1924For example, to detach a virtual device port 0.
1925
1926.. code-block:: console
1927
1928   testpmd> port stop 0
1929   Stopping ports...
1930   Done
1931   testpmd> port close 0
1932   Closing ports...
1933   Done
1934
1935   testpmd> port detach 0
1936   Detaching a port...
1937   PMD: Closing pcap ethdev on numa socket 0
1938   Port 'net_pcap0' is detached. Now total ports is 0
1939   Done
1940
1941To remove a pci device completely from the system, first detach the port from testpmd.
1942Then the device should be moved under kernel management.
1943Finally the device can be removed using kernel pci hotplug functionality.
1944
1945For example, to move a pci device under kernel management:
1946
1947.. code-block:: console
1948
1949   sudo ./usertools/dpdk-devbind.py -b ixgbe 0000:0a:00.0
1950
1951   ./usertools/dpdk-devbind.py --status

2193Set Tx metadata value per port.
2194testpmd will add this value to any Tx packet sent from this port::
2195
2196   testpmd> port config (port_id) tx_metadata (value)
2197
2198port config dynf
2199~~~~~~~~~~~~~~~~
2200
2201Set/clear dynamic flag per port.
2202testpmd will register this flag in the mbuf (same registration
2203for both Tx and Rx). Then set/clear this flag for each Tx
2204packet sent from this port. The set bit only works for Tx packet::
2205
2206   testpmd> port config (port_id) dynf (name) (set|clear)
2207
2208port config mtu
2209~~~~~~~~~~~~~~~
2210
2211To configure MTU(Maximum Transmission Unit) on devices using testpmd::
2212
2213   testpmd> port config mtu (port_id) (value)
2214
2215port config rss hash key
2216~~~~~~~~~~~~~~~~~~~~~~~~
2217
2218To configure the RSS hash key used to compute the RSS
2219hash of input [IP] packets received on port::
2220
2221   testpmd> port config <port_id> rss-hash-key (ipv4|ipv4-frag|\
2222                     ipv4-tcp|ipv4-udp|ipv4-sctp|ipv4-other|\
2223                     ipv6|ipv6-frag|ipv6-tcp|ipv6-udp|ipv6-sctp|\
2224                     ipv6-other|l2-payload|ipv6-ex|ipv6-tcp-ex|\
2225                     ipv6-udp-ex <string of hex digits \
2226                     (variable length, NIC dependent)>)
2227
2228port cleanup txq mbufs
2229~~~~~~~~~~~~~~~~~~~~~~
2230
2231To cleanup txq mbufs currently cached by driver::
2232
2233   testpmd> port cleanup (port_id) txq (queue_id) (free_cnt)
2234
2235If the value of ``free_cnt`` is 0, driver should free all cached mbufs.
2236
2237Device Functions
2238----------------
2239
2240The following sections show functions for device operations.
2241
2242device detach
2243~~~~~~~~~~~~~
2244
2245Detach a device specified by pci address or virtual device args::
2246
2247   testpmd> device detach (identifier)
2248
2249Before detaching a device associated with ports, the ports should be stopped and closed.
2250
2251For example, to detach a pci device whose address is 0002:03:00.0.
2252
2253.. code-block:: console
2254
2255    testpmd> device detach 0002:03:00.0
2256    Removing a device...
2257    Port 1 is now closed
2258    EAL: Releasing pci mapped resource for 0002:03:00.0
2259    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218a050000
2260    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218c050000
2261    Device 0002:03:00.0 is detached
2262    Now total ports is 1
2263
2264For example, to detach a port created by pcap PMD.
2265
2266.. code-block:: console
2267
2268    testpmd> device detach net_pcap0
2269    Removing a device...
2270    Port 0 is now closed
2271    Device net_pcap0 is detached
2272    Now total ports is 0
2273    Done
2274
2275In this case, identifier is ``net_pcap0``.
2276This identifier format is the same as ``--vdev`` format of DPDK applications.
2277

2846Filter Functions
2847----------------
2848
2849This section details the available filter functions that are available.
2850
2851Note these functions interface the deprecated legacy filtering framework,
2852superseded by *rte_flow*. See `Flow rules management`_.
2853
2854.. _testpmd_rte_flow:
2855
2856Flow rules management
2857---------------------
2858
2859Control of the generic flow API (*rte_flow*) is fully exposed through the
2860``flow`` command (configuration, validation, creation, destruction, queries
2861and operation modes).
2862
2863Considering *rte_flow* overlaps with all `Filter Functions`_, using both
2864features simultaneously may cause undefined side-effects and is therefore
2865not recommended.
2866
2867``flow`` syntax
2868~~~~~~~~~~~~~~~
2869
2870Because the ``flow`` command uses dynamic tokens to handle the large number
2871of possible flow rules combinations, its behavior differs slightly from
2872other commands, in particular:
2873
2874- Pressing *?* or the *<tab>* key displays contextual help for the current
2875  token, not that of the entire command.
2876
2877- Optional and repeated parameters are supported (provided they are listed
2878  in the contextual help).
2879
2880The first parameter stands for the operation mode. Possible operations and
2881their general syntax are described below. They are covered in detail in the
2882following sections.

3279Creating flow rules
3280~~~~~~~~~~~~~~~~~~~
3281
3282``flow create`` validates and creates the specified flow rule. It is bound
3283to ``rte_flow_create()``::
3284
3285   flow create {port_id}
3286      [group {group_id}] [priority {level}] [ingress] [egress] [transfer]
3287      [tunnel_set {tunnel_id}] [tunnel_match {tunnel_id}]
3288      pattern {item} [/ {item} [...]] / end
3289      actions {action} [/ {action} [...]] / end
3290
3291If successful, it will return a flow rule ID usable with other commands::
3292
3293   Flow rule #[...] created
3294
3295Otherwise it will show an error message of the form::
3296
3297   Caught error type [...] ([...]): [...]
3298
3299Parameters describe in the following order:
3300
3301- Attributes (*group*, *priority*, *ingress*, *egress*, *transfer* tokens).
3302- Tunnel offload specification (tunnel_set, tunnel_match)
3303- A matching pattern, starting with the *pattern* token and terminated by an
3304  *end* pattern item.
3305- Actions, starting with the *actions* token and terminated by an *end*
3306  action.
3307
3308These translate directly to *rte_flow* objects provided as-is to the
3309underlying functions.
3310
3311The shortest valid definition only comprises mandatory tokens::
3312
3313   testpmd> flow create 0 pattern end actions end
3314
3315Note that PMDs may refuse rules that essentially do nothing such as this
3316one.
3317
3318**All unspecified object values are automatically initialized to 0.**
3319
3320Enqueueing creation of flow rules
3321~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3322
3323``flow queue create`` adds creation operation of a flow rule to a queue.
3324It is bound to ``rte_flow_async_create()``::
3325
3326   flow queue {port_id} create {queue_id}
3327       [postpone {boolean}] template_table {table_id}
3328       pattern_template {pattern_template_index}
3329       actions_template {actions_template_index}
3330       pattern {item} [/ {item} [...]] / end
3331       actions {action} [/ {action} [...]] / end
3332
3333If successful, it will return a flow rule ID usable with other commands::
3334
3335   Flow rule #[...] creaion enqueued
3336
3337Otherwise it will show an error message of the form::
3338
3339   Caught error type [...] ([...]): [...]
3340
3341This command uses the same pattern items and actions as ``flow create``,
3342their format is described in `Creating flow rules`_.
3343
3344``flow queue pull`` must be called to retrieve the operation status.
3345
3346Attributes
3347^^^^^^^^^^
3348
3349These tokens affect flow rule attributes (``struct rte_flow_attr``) and are
3350specified before the ``pattern`` token.
3351
3352- ``group {group id}``: priority group.
3353- ``priority {level}``: priority level within group.
3354- ``ingress``: rule applies to ingress traffic.
3355- ``egress``: rule applies to egress traffic.
3356- ``transfer``: apply rule directly to endpoints found in pattern.
3357
3358Please note that use of ``transfer`` attribute requires that the flow and
3359its indirect components be managed via so-called ``transfer`` proxy port.
3360See `show flow transfer proxy port ID for the given port`_ for details.
3361
3362Each instance of an attribute specified several times overrides the previous
3363value as shown below (group 4 is used)::
3364
3365   testpmd> flow create 0 group 42 group 24 group 4 [...]
3366
3367Note that once enabled, ``ingress`` and ``egress`` cannot be disabled.
3368
3369While not specifying a direction is an error, some rules may allow both
3370simultaneously.
3371
3372Most rules affect RX therefore contain the ``ingress`` token::
3373
3374   testpmd> flow create 0 ingress pattern [...]
3375
3376Tunnel offload
3377^^^^^^^^^^^^^^
3378
3379Indicate tunnel offload rule type
3380
3381- ``tunnel_set {tunnel_id}``: mark rule as tunnel offload decap_set type.
3382- ``tunnel_match {tunnel_id}``:  mark rule as tunnel offload match type.
3383
3384Matching pattern
3385^^^^^^^^^^^^^^^^
3386
3387A matching pattern starts after the ``pattern`` token. It is made of pattern
3388items and is terminated by a mandatory ``end`` item.
3389
3390Items are named after their type (*RTE_FLOW_ITEM_TYPE_* from ``enum
3391rte_flow_item_type``).
3392
3393The ``/`` token is used as a separator between pattern items as shown
3394below::
3395
3396   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end [...]
3397
3398Note that protocol items like these must be stacked from lowest to highest
3399layer to make sense. For instance, the following rule is either invalid or
3400unlikely to match any packet::
3401
3402   testpmd> flow create 0 ingress pattern eth / udp / ipv4 / end [...]
3403
3404More information on these restrictions can be found in the *rte_flow*
3405documentation.
3406
3407Several items support additional specification structures, for example
3408``ipv4`` allows specifying source and destination addresses as follows::
3409
3410   testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.1.1.1
3411      dst is 10.2.0.0 / end [...]
3412
3413This rule matches all IPv4 traffic with the specified properties.
3414
3415In this example, ``src`` and ``dst`` are field names of the underlying
3416``struct rte_flow_item_ipv4`` object. All item properties can be specified
3417in a similar fashion.
3418
3419The ``is`` token means that the subsequent value must be matched exactly,
3420and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item``
3421accordingly. Possible assignment tokens are:
3422
3423- ``is``: match value perfectly (with full bit-mask).
3424- ``spec``: match value according to configured bit-mask.
3425- ``last``: specify upper bound to establish a range.
3426- ``mask``: specify bit-mask with relevant bits set to one.
3427- ``prefix``: generate bit-mask with <prefix-length> most-significant bits set to one.
3428
3429These yield identical results::
3430
3431   ipv4 src is 10.1.1.1
3432
3433::
3434
3435   ipv4 src spec 10.1.1.1 src mask 255.255.255.255
3436
3437::
3438
3439   ipv4 src spec 10.1.1.1 src prefix 32
3440
3441::
3442
3443   ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value
3444
3445::
3446
3447   ipv4 src is 10.1.1.1 src last 0 # 0 disables range
3448
3449Inclusive ranges can be defined with ``last``::
3450
3451   ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4
3452
3453Note that ``mask`` affects both ``spec`` and ``last``::
3454
3455   ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0
3456      # matches 10.1.0.0 to 10.2.255.255
3457
3458Properties can be modified multiple times::
3459
3460   ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4
3461
3462::
3463
3464   ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16
3465

3716
3717Actions list
3718^^^^^^^^^^^^
3719
3720A list of actions starts after the ``actions`` token in the same fashion as
3721`Matching pattern`_; actions are separated by ``/`` tokens and the list is
3722terminated by a mandatory ``end`` action.
3723
3724Actions are named after their type (*RTE_FLOW_ACTION_TYPE_* from ``enum
3725rte_flow_action_type``).
3726
3727Dropping all incoming UDPv4 packets can be expressed as follows::
3728
3729   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3730      actions drop / end
3731
3732Several actions have configurable properties which must be specified when
3733there is no valid default value. For example, ``queue`` requires a target
3734queue index.
3735
3736This rule redirects incoming UDPv4 traffic to queue index 6::
3737
3738   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3739      actions queue index 6 / end
3740
3741While this one could be rejected by PMDs (unspecified queue index)::
3742
3743   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end
3744      actions queue / end
3745
3746As defined by *rte_flow*, the list is not ordered, all actions of a given
3747rule are performed simultaneously. These are equivalent::
3748
3749   queue index 6 / void / mark id 42 / end
3750
3751::
3752
3753   void / mark id 42 / queue index 6 / end
3754
3755All actions in a list should have different types, otherwise only the last
3756action of a given type is taken into account::
3757
3758   queue index 4 / queue index 5 / queue index 6 / end # will use queue 6
3759
3760::
3761
3762   drop / drop / drop / end # drop is performed only once
3763
3764::
3765
3766   mark id 42 / queue index 3 / mark id 24 / end # mark will be 24
3767
3768Considering they are performed simultaneously, opposite and overlapping
3769actions can sometimes be combined when the end result is unambiguous::
3770
3771   drop / queue index 6 / end # drop has no effect
3772
3773::
3774
3775   queue index 6 / rss queues 6 7 8 / end # queue has no effect
3776
3777::
3778
3779   drop / passthru / end # drop has no effect
3780
3781Note that PMDs may still refuse such combinations.
3782

4005Destroying flow rules
4006~~~~~~~~~~~~~~~~~~~~~
4007
4008``flow destroy`` destroys one or more rules from their rule ID (as returned
4009by ``flow create``), this command calls ``rte_flow_destroy()`` as many
4010times as necessary::
4011
4012   flow destroy {port_id} rule {rule_id} [...]
4013
4014If successful, it will show::
4015
4016   Flow rule #[...] destroyed
4017
4018It does not report anything for rule IDs that do not exist. The usual error
4019message is shown when a rule cannot be destroyed::
4020
4021   Caught error type [...] ([...]): [...]
4022
4023``flow flush`` destroys all rules on a device and does not take extra
4024arguments. It is bound to ``rte_flow_flush()``::
4025
4026   flow flush {port_id}
4027
4028Any errors are reported as above.
4029
4030Creating several rules and destroying them::
4031
4032   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4033      actions queue index 2 / end
4034   Flow rule #0 created
4035   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4036      actions queue index 3 / end
4037   Flow rule #1 created
4038   testpmd> flow destroy 0 rule 0 rule 1
4039   Flow rule #1 destroyed
4040   Flow rule #0 destroyed
4041   testpmd>
4042
4043The same result can be achieved using ``flow flush``::
4044
4045   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4046      actions queue index 2 / end
4047   Flow rule #0 created
4048   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4049      actions queue index 3 / end
4050   Flow rule #1 created
4051   testpmd> flow flush 0
4052   testpmd>
4053
4054Non-existent rule IDs are ignored::
4055
4056   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4057      actions queue index 2 / end
4058   Flow rule #0 created
4059   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4060      actions queue index 3 / end
4061   Flow rule #1 created
4062   testpmd> flow destroy 0 rule 42 rule 10 rule 2
4063   testpmd>
4064   testpmd> flow destroy 0 rule 0
4065   Flow rule #0 destroyed
4066   testpmd>
4067
4068Enqueueing destruction of flow rules
4069~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4070
4071``flow queue destroy`` adds destruction operations to destroy one or more rules
4072from their rule ID (as returned by ``flow queue create``) to a queue,
4073this command calls ``rte_flow_async_destroy()`` as many times as necessary::
4074
4075   flow queue {port_id} destroy {queue_id}
4076        [postpone {boolean}] rule {rule_id} [...]
4077
4078If successful, it will show::
4079
4080   Flow rule #[...] destruction enqueued
4081
4082It does not report anything for rule IDs that do not exist. The usual error
4083message is shown when a rule cannot be destroyed::
4084
4085   Caught error type [...] ([...]): [...]
4086
4087``flow queue pull`` must be called to retrieve the operation status.
4088
4089Querying flow rules
4090~~~~~~~~~~~~~~~~~~~
4091
4092``flow query`` queries a specific action of a flow rule having that
4093ability. Such actions collect information that can be reported using this
4094command. It is bound to ``rte_flow_query()``::
4095
4096   flow query {port_id} {rule_id} {action}
4097
4098If successful, it will display either the retrieved data for known actions
4099or the following message::
4100
4101   Cannot display result for action type [...] ([...])
4102
4103Otherwise, it will complain either that the rule does not exist or that some
4104error occurred::
4105
4106   Flow rule #[...] not found
4107
4108::
4109
4110   Caught error type [...] ([...]): [...]
4111
4112Currently only the ``count`` action is supported. This action reports the
4113number of packets that hit the flow rule and the total number of bytes. Its
4114output has the following format::
4115
4116   count:
4117    hits_set: [...] # whether "hits" contains a valid value
4118    bytes_set: [...] # whether "bytes" contains a valid value
4119    hits: [...] # number of packets
4120    bytes: [...] # number of bytes
4121
4122Querying counters for TCPv6 packets redirected to queue 6::
4123
4124   testpmd> flow create 0 ingress pattern eth / ipv6 / tcp / end
4125      actions queue index 6 / count / end
4126   Flow rule #4 created
4127   testpmd> flow query 0 4 count
4128   count:
4129    hits_set: 1
4130    bytes_set: 0
4131    hits: 386446
4132    bytes: 0
4133   testpmd>
4134
4135Listing flow rules
4136~~~~~~~~~~~~~~~~~~
4137
4138``flow list`` lists existing flow rules sorted by priority and optionally
4139filtered by group identifiers::
4140
4141   flow list {port_id} [group {group_id}] [...]
4142
4143This command only fails with the following message if the device does not
4144exist::
4145
4146   Invalid port [...]
4147
4148Output consists of a header line followed by a short description of each
4149flow rule, one per line. There is no output at all when no flow rules are
4150configured on the device::
4151
4152   ID      Group   Prio    Attr    Rule
4153   [...]   [...]   [...]   [...]   [...]
4154
4155``Attr`` column flags:
4156
4157- ``i`` for ``ingress``.
4158- ``e`` for ``egress``.
4159
4160Creating several flow rules and listing them::
4161
4162   testpmd> flow create 0 ingress pattern eth / ipv4 / end
4163      actions queue index 6 / end
4164   Flow rule #0 created
4165   testpmd> flow create 0 ingress pattern eth / ipv6 / end
4166      actions queue index 2 / end
4167   Flow rule #1 created
4168   testpmd> flow create 0 priority 5 ingress pattern eth / ipv4 / udp / end
4169      actions rss queues 6 7 8 end / end
4170   Flow rule #2 created
4171   testpmd> flow list 0
4172   ID      Group   Prio    Attr    Rule
4173   0       0       0       i-      ETH IPV4 => QUEUE
4174   1       0       0       i-      ETH IPV6 => QUEUE
4175   2       0       5       i-      ETH IPV4 UDP => RSS
4176   testpmd>
4177
4178Rules are sorted by priority (i.e. group ID first, then priority level)::
4179
4180   testpmd> flow list 1
4181   ID      Group   Prio    Attr    Rule
4182   0       0       0       i-      ETH => COUNT
4183   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4184   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
4185   1       24      0       i-      ETH IPV4 UDP => QUEUE
4186   4       24      10      i-      ETH IPV4 TCP => DROP
4187   3       24      20      i-      ETH IPV4 => DROP
4188   2       24      42      i-      ETH IPV4 UDP => QUEUE
4189   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
4190   testpmd>
4191
4192Output can be limited to specific groups::
4193
4194   testpmd> flow list 1 group 0 group 63
4195   ID      Group   Prio    Attr    Rule
4196   0       0       0       i-      ETH => COUNT
4197   6       0       500     i-      ETH IPV6 TCP => DROP COUNT
4198   5       0       1000    i-      ETH IPV6 ICMP => QUEUE
4199   7       63      0       i-      ETH IPV6 UDP VXLAN => MARK QUEUE
4200   testpmd>
4201
4202Toggling isolated mode
4203~~~~~~~~~~~~~~~~~~~~~~
4204
4205``flow isolate`` can be used to tell the underlying PMD that ingress traffic
4206must only be injected from the defined flow rules; that no default traffic
4207is expected outside those rules and the driver is free to assign more
4208resources to handle them. It is bound to ``rte_flow_isolate()``::
4209
4210 flow isolate {port_id} {boolean}
4211
4212If successful, enabling or disabling isolated mode shows either::
4213
4214 Ingress traffic on port [...]
4215    is now restricted to the defined flow rules
4216
4217Or::
4218
4219 Ingress traffic on port [...]
4220    is not restricted anymore to the defined flow rules
4221
4222Otherwise, in case of error::
4223
4224   Caught error type [...] ([...]): [...]
4225
4226Mainly due to its side effects, PMDs supporting this mode may not have the
4227ability to toggle it more than once without reinitializing affected ports
4228first (e.g. by exiting testpmd).
4229
4230Enabling isolated mode::
4231
4232 testpmd> flow isolate 0 true
4233 Ingress traffic on port 0 is now restricted to the defined flow rules
4234 testpmd>
4235
4236Disabling isolated mode::
4237
4238 testpmd> flow isolate 0 false
4239 Ingress traffic on port 0 is not restricted anymore to the defined flow rules
4240 testpmd>
4241
4242Dumping HW internal information
4243~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4244
4245``flow dump`` dumps the hardware's internal representation information of
4246all flows. It is bound to ``rte_flow_dev_dump()``::
4247
4248   flow dump {port_id} {output_file}
4249
4250If successful, it will show::
4251
4252   Flow dump finished
4253
4254Otherwise, it will complain error occurred::
4255
4256   Caught error type [...] ([...]): [...]
4257
4258Listing and destroying aged flow rules
4259~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4260
4261``flow aged`` simply lists aged flow rules be get from api ``rte_flow_get_aged_flows``,
4262and ``destroy`` parameter can be used to destroy those flow rules in PMD.
4263
4264   flow aged {port_id} [destroy]
4265
4266Listing current aged flow rules::
4267
4268   testpmd> flow aged 0
4269   Port 0 total aged flows: 0
4270   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.14 / end
4271      actions age timeout 5 / queue index 0 /  end
4272   Flow rule #0 created
4273   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.15 / end
4274      actions age timeout 4 / queue index 0 /  end
4275   Flow rule #1 created
4276   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.16 / end
4277      actions age timeout 2 / queue index 0 /  end
4278   Flow rule #2 created
4279   testpmd> flow create 0 ingress pattern eth / ipv4 src is 2.2.2.17 / end
4280      actions age timeout 3 / queue index 0 /  end
4281   Flow rule #3 created
4282
4283
4284Aged Rules are simply list as command ``flow list {port_id}``, but strip the detail rule
4285information, all the aged flows are sorted by the longest timeout time. For example, if
4286those rules be configured in the same time, ID 2 will be the first aged out rule, the next
4287will be ID 3, ID 1, ID 0::
4288
4289   testpmd> flow aged 0
4290   Port 0 total aged flows: 4

4316Enqueueing listing and destroying aged flow rules
4317~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4318
4319``flow queue aged`` simply lists aged flow rules be get from
4320``rte_flow_get_q_aged_flows`` API, and ``destroy`` parameter can be used to
4321destroy those flow rules in PMD::
4322
4323   flow queue {port_id} aged {queue_id} [destroy]
4324
4325Listing current aged flow rules::
4326
4327   testpmd> flow queue 0 aged 0
4328   Port 0 queue 0 total aged flows: 0
4329   testpmd> flow queue 0 create 0 ingress tanle 0 item_template 0 action_template 0
4330      pattern eth / ipv4 src is 2.2.2.14 / end
4331      actions age timeout 5 / queue index 0 /  end
4332   Flow rule #0 creation enqueued
4333   testpmd> flow queue 0 create 0 ingress tanle 0 item_template 0 action_template 0

5066 testpmd> flow create 0 group 5 ingress pattern eth / ipv4 / tcp / conntrack is 1 / end actions queue index 5 / end
5067
5068Construct the conntrack again with only "is_orig" set to 0 (other fields are
5069ignored), then use "update" interface to update the direction. Create flow
5070rules like above for the peer port.
5071
5072::
5073
5074 testpmd> flow indirect_action 0 update 0 action conntrack_update dir / end

5136Sample RAW rule
5137~~~~~~~~~~~~~~~
5138
5139A RAW rule can be created as following using ``pattern_hex`` key and mask.
5140
5141::
5142
5143    testpmd> flow create 0 group 0 priority 1 ingress pattern raw relative is 0 search is 0 offset
5144             is 0 limit is 0 pattern_hex spec 00000000000000000000000000000000000000000000000000000a0a0a0a
5145             pattern_hex mask 0000000000000000000000000000000000000000000000000000ffffffff / end actions
5146             queue index 4 / end
5147
5148BPF Functions
5149--------------
5150
5151The following sections show functions to load/unload eBPF based filters.
5152
5153bpf-load
5154~~~~~~~~
5155
5156Load an eBPF program as a callback for particular RX/TX queue::
5157
5158   testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename)
5159
5160The available load-flags are:
5161
5162* ``J``: use JIT generated native code, otherwise BPF interpreter will be used.
5163
5164* ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data.
5165
5166* ``-``: none.
5167
5168.. note::
5169
5170   You'll need clang v3.7 or above to build bpf program you'd like to load
5171
5172For example:
5173
5174.. code-block:: console
5175
5176   cd examples/bpf
5177   clang -O2 -target bpf -c t1.c
5178
5179Then to load (and JIT compile) t1.o at RX queue 0, port 1:
5180
5181.. code-block:: console
5182
5183   testpmd> bpf-load rx 1 0 J ./dpdk.org/examples/bpf/t1.o
5184
5185To load (not JITed) t1.o at TX queue 0, port 0:
5186
5187.. code-block:: console
5188
5189   testpmd> bpf-load tx 0 0 - ./dpdk.org/examples/bpf/t1.o
5190
5191bpf-unload
5192~~~~~~~~~~
5193
5194Unload previously loaded eBPF program for particular RX/TX queue::
5195
5196   testpmd> bpf-unload rx|tx (portid) (queueid)
5197
5198For example to unload BPF filter from TX queue 0, port 0:
5199
5200.. code-block:: console
5201
5202   testpmd> bpf-unload tx 0 0
5203
5204Flex Item Functions
5205-------------------
5206
5207The following sections show functions that configure and create flex item object,
5208create flex pattern and use it in a flow rule.
5209The commands will use 20 bytes IPv4 header for examples:
5210
5211::
5212
5213   0                   1                   2                   3

5228Create flex item
5229~~~~~~~~~~~~~~~~
5230
5231Flex item object is created by PMD according to a new header configuration. The
5232header configuration is compiled by the testpmd and stored in
5233``rte_flow_item_flex_conf`` type variable.
5234
5235::
5236
5237   # flow flex_item create <port> <flex id> <configuration file>
5238   testpmd> flow flex_item init 0 3 ipv4_flex_config.json
5239   port-0: created flex item #3
5240
5241Flex item configuration is kept in external JSON file.
5242It describes the following header elements:
5243
5244**New header length.**
5245
5246Specify whether the new header has fixed or variable length and the basic/minimal
5247header length value.
5248
5249If header length is not fixed, header location with a value that completes header
5250length calculation and scale/offset function must be added.
5251
5252Scale function depends on port hardware.
5253
5254**Next protocol.**
5255
5256Describes location in the new header that specify following network header type.
5257
5258**Flow match samples.**
5259
5260Describes locations in the new header that will be used in flow rules.
5261
5262Number of flow samples and sample maximal length depend of port hardware.
5263
5264**Input trigger.**
5265
5266Describes preceding network header configuration.
5267
5268**Output trigger.**
5269
5270Describes conditions that trigger transfer to following network header
5271
5272.. code-block:: json

5294
5295Flex pattern and flow rules
5296~~~~~~~~~~~~~~~~~~~~~~~~~~~
5297
5298Flex pattern describe parts of network header that will trigger flex flow item hit in a flow rule.
5299Flex pattern directly related to flex item samples configuration.
5300Flex pattern can be shared between ports.
5301
5302**Flex pattern and flow rule to match IPv4 version and 20 bytes length**
5303
5304::
5305
5306   # set flex_pattern <pattern_id> is <hex bytes sequence>
5307   testpmd> flow flex_item pattern 5 is 45FF
5308   created pattern #5
5309
5310   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / flex item is 3 pattern is 5 / end actions mark id 1 / queue index 0 / end
5311   Flow rule #0 created
5312
5313**Flex pattern and flow rule to match packets with source address 1.2.3.4**
5314
5315::
5316
5317   testpmd> flow flex_item pattern 2 spec 45000000000000000000000001020304 mask FF0000000000000000000000FFFFFFFF
5318   created pattern #2
5319
5320   testpmd> flow create 0 ingress pattern eth / ipv4 / udp / flex item is 3 pattern is 2 / end actions mark id 1 / queue index 0 / end
5321   Flow rule #0 created
