The user may specify a target destination Ethernet address via the 'eth-peer' or 330 'eth-peers-configfile' command-line options. It is not currently possible to specify a specific source Ethernet address. 331 332* ``macswap``: MAC swap forwarding mode. 333 Swaps the source and the destination Ethernet addresses of packets before forwarding them. 334 335* ``flowgen``: Multi-flow generation mode. 336 Originates a number of flows (with varying destination IP addresses), and terminate receive traffic. 337 338* ``rxonly``: Receives packets but doesn't transmit them. 339 340* ``txonly``: Generates and transmits packets without receiving any. 341 342* ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet. 343 344* ``icmpecho``: Receives a burst of packets, lookup for ICMP echo requests and, if any, send back ICMP echo replies. 345 346* ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX. 347 348* ``noisy``: Noisy neighbor simulation. 349 Simulate more realistic behavior of a guest machine engaged in receiving 350 and sending packets performing Virtual Network Function (VNF). 351 352* ``5tswap``: Swap the source and destination of L2,L3,L4 if they exist. 353 354 L2 swaps the source address and destination address of Ethernet, as same as ``macswap``. 355 356 L3 swaps the source address and destination address of IP (v4 and v6). 357 358 L4 swaps the source port and destination port of transport layer (TCP and UDP).

Optionally the multiple memory 798pools can be specified with --mbuf-size command line parameter and the mbufs 799to receive will be allocated sequentially from these extra memory pools (the 800mbuf for the first segment is allocated from the first pool, the second one 801from the second pool, and so on, if segment number is greater then pool's the 802mbuf for remaining segments will be allocated from the last valid pool). 803 804 testpmd> set rxpkts (x[,y]*) 805 806Where x[,y]* represents a CSV list of values, without white space.

This command enables 822the packet send scheduling on dynamic timestamp mbuf field and configures 823timing pattern in Tx only mode. In this mode, if scheduling is enabled 824application provides timestamps in the packets being sent. It is possible 825to configure delay (in unspecified device clock units) between bursts 826and between the packets within the burst:: 827 828 testpmd> set txtimes (inter),(intra) 829 830where: 831 832* ``inter`` is the delay between the bursts in the device clock units. 833 If ``intra`` is zero, this is the time between the beginnings of the 834 first packets in the neighbour bursts, if ``intra`` is not zero, 835 ``inter`` specifies the time between the beginning of the first packet 836 of the current burst and the beginning of the last packet of the 837 previous burst. If ``inter`` parameter is zero the send scheduling 838 on timestamps is disabled (default). 839 840* ``intra`` is the delay between the packets within the burst specified 841 in the device clock units. The number of packets in the burst is defined 842 by regular burst setting. If ``intra`` parameter is zero no timestamps 843 provided in the packets excepting the first one in the burst. 844 845As the result the bursts of packet will be transmitted with specific 846delays between the packets within the burst and specific delay between 847the bursts. The rte_eth_read_clock() must be supported by the device(s) 848and is supposed to be engaged to get the current device clock value 849and provide the reference for the timestamps. If there is no supported 850rte_eth_read_clock() there will be no send scheduling provided on the port. 851 852set txsplit 853~~~~~~~~~~~ 854 855Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes:: 856 857 testpmd> set txsplit (off|on|rand) 858 859Where: 860 861* ``off`` disable packet copy & split for CSUM mode. 862 863* ``on`` split outgoing packet into multiple segments.

By default, GRO is disabled for all ports. 1272 1273.. note:: 1274 1275 When enable GRO for a port, TCP/IPv4 packets received from the port 1276 will be performed GRO. After GRO, all merged packets have bad 1277 checksums, since the GRO library doesn't re-calculate checksums for 1278 the merged packets. Therefore, if users want the merged packets to 1279 have correct checksums, please select HW IP checksum calculation and 1280 HW TCP checksum calculation for the port which the merged packets are 1281 transmitted to. 1282 1283show port - gro 1284~~~~~~~~~~~~~~~ 1285 1286Display GRO configuration for a given port:: 1287 1288 testpmd> show port <port_id> gro 1289 1290set gro flush 1291~~~~~~~~~~~~~ 1292 1293Set the cycle to flush the GROed packets from reassembly tables:: 1294 1295 testpmd> set gro flush <cycles> 1296 1297When enable GRO, the csum forwarding engine performs GRO on received 1298packets, and the GROed packets are stored in reassembly tables. Users 1299can use this command to determine when the GROed packets are flushed 1300from the reassembly tables. 1301 1302The ``cycles`` is measured in GRO operation times. The csum forwarding 1303engine flushes the GROed packets from the tables every ``cycles`` GRO 1304operations. 1305 1306By default, the value of ``cycles`` is 1, which means flush GROed packets 1307from the reassembly tables as soon as one GRO operation finishes. The value 1308of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``. 1309 1310Please note that the large value of ``cycles`` may cause the poor TCP/IP 1311stack performance. Because the GROed packets are delayed to arrive the 1312stack, thus causing more duplicated ACKs and TCP retransmissions. 1313 1314set port - gso 1315~~~~~~~~~~~~~~ 1316 1317Toggle per-port GSO support in ``csum`` forwarding engine:: 1318 1319 testpmd> set port <port_id> gso on|off 1320 1321If enabled, the csum forwarding engine will perform GSO on supported IPv4 1322packets, transmitted on the given port. 1323 1324If disabled, packets transmitted on the given port will not undergo GSO. 1325By default, GSO is disabled for all ports. 1326 1327.. note:: 1328 1329 When GSO is enabled on a port, supported IPv4 packets transmitted on that 1330 port undergo GSO. Afterwards, the segmented packets are represented by 1331 multi-segment mbufs; however, the csum forwarding engine doesn't calculation 1332 of checksums for GSO'd segments in SW. As a result, if users want correct 1333 checksums in GSO segments, they should enable HW checksum calculation for 1334 GSO-enabled ports. 1335 1336 For example, HW checksum calculation for VxLAN GSO'd packets may be enabled 1337 by setting the following options in the csum forwarding engine: 1338 1339 testpmd> csum set outer_ip hw <port_id> 1340 1341 testpmd> csum set ip hw <port_id> 1342 1343 testpmd> csum set tcp hw <port_id> 1344 1345 UDP GSO is the same as IP fragmentation, which treats the UDP header 1346 as the payload and does not modify it during segmentation. That is, 1347 after UDP GSO, only the first output fragment has the original UDP 1348 header. Therefore, users need to enable HW IP checksum calculation 1349 and SW UDP checksum calculation for GSO-enabled ports, if they want 1350 correct checksums for UDP/IPv4 packets. 1351 1352set gso segsz 1353~~~~~~~~~~~~~ 1354 1355Set the maximum GSO segment size (measured in bytes), which includes the 1356packet header and the packet payload for GSO-enabled ports (global):: 1357 1358 testpmd> set gso segsz <length> 1359 1360show port - gso 1361~~~~~~~~~~~~~~~ 1362 1363Display the status of Generic Segmentation Offload for a given port:: 1364 1365 testpmd> show port <port_id> gso 1366 1367mac_addr add 1368~~~~~~~~~~~~ 1369 1370Add an alternative MAC address to a port:: 1371 1372 testpmd> mac_addr add (port_id) (XX:XX:XX:XX:XX:XX) 1373 1374mac_addr remove 1375~~~~~~~~~~~~~~~ 1376 1377Remove a MAC address from a port:: 1378 1379 testpmd> mac_addr remove (port_id) (XX:XX:XX:XX:XX:XX) 1380 1381mcast_addr add 1382~~~~~~~~~~~~~~ 1383 1384To add the multicast MAC address to/from the set of multicast addresses 1385filtered by port:: 1386 1387 testpmd> mcast_addr add (port_id) (mcast_addr) 1388 1389mcast_addr remove 1390~~~~~~~~~~~~~~~~~ 1391 1392To remove the multicast MAC address to/from the set of multicast addresses 1393filtered by port:: 1394 1395 testpmd> mcast_addr remove (port_id) (mcast_addr) 1396 1397mac_addr add (for VF) 1398~~~~~~~~~~~~~~~~~~~~~ 1399 1400Add an alternative MAC address for a VF to a port:: 1401 1402 testpmd> mac_add add port (port_id) vf (vf_id) (XX:XX:XX:XX:XX:XX) 1403 1404mac_addr set 1405~~~~~~~~~~~~ 1406 1407Set the default MAC address for a port:: 1408 1409 testpmd> mac_addr set (port_id) (XX:XX:XX:XX:XX:XX) 1410 1411mac_addr set (for VF) 1412~~~~~~~~~~~~~~~~~~~~~ 1413 1414Set the MAC address for a VF from the PF:: 1415 1416 testpmd> set vf mac addr (port_id) (vf_id) (XX:XX:XX:XX:XX:XX) 1417 1418set eth-peer 1419~~~~~~~~~~~~ 1420 1421Set the forwarding peer address for certain port:: 1422 1423 testpmd> set eth-peer (port_id) (peer_addr) 1424 1425This is equivalent to the ``--eth-peer`` command-line option. 1426 1427set port-uta 1428~~~~~~~~~~~~ 1429 1430Set the unicast hash filter(s) on/off for a port:: 1431 1432 testpmd> set port (port_id) uta (XX:XX:XX:XX:XX:XX|all) (on|off) 1433 1434set promisc 1435~~~~~~~~~~~ 1436 1437Set the promiscuous mode on for a port or for all ports. 1438In promiscuous mode packets are not dropped if they aren't for the specified MAC address:: 1439 1440 testpmd> set promisc (port_id|all) (on|off) 1441 1442set allmulti 1443~~~~~~~~~~~~ 1444 1445Set the allmulti mode for a port or for all ports:: 1446 1447 testpmd> set allmulti (port_id|all) (on|off) 1448 1449Same as the ifconfig (8) option.

For example, ``queue`` requires a target 3809queue index. 3810 3811This rule redirects incoming UDPv4 traffic to queue index 6:: 3812 3813 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end 3814 actions queue index 6 / end 3815 3816While this one could be rejected by PMDs (unspecified queue index):: 3817 3818 testpmd> flow create 0 ingress pattern eth / ipv4 / udp / end 3819 actions queue / end 3820 3821As defined by *rte_flow*, the list is not ordered, all actions of a given 3822rule are performed simultaneously. These are equivalent:: 3823 3824 queue index 6 / void / mark id 42 / end 3825 3826:: 3827 3828 void / mark id 42 / queue index 6 / end 3829 3830All actions in a list should have different types, otherwise only the last 3831action of a given type is taken into account:: 3832 3833 queue index 4 / queue index 5 / queue index 6 / end # will use queue 6 3834 3835:: 3836 3837 drop / drop / drop / end # drop is performed only once 3838 3839:: 3840 3841 mark id 42 / queue index 3 / mark id 24 / end # mark will be 24 3842 3843Considering they are performed simultaneously, opposite and overlapping 3844actions can sometimes be combined when the end result is unambiguous:: 3845 3846 drop / queue index 6 / end # drop has no effect 3847 3848:: 3849 3850 queue index 6 / rss queues 6 7 8 / end # queue has no effect 3851 3852:: 3853 3854 drop / passthru / end # drop has no effect 3855 3856Note that PMDs may still refuse such combinations. 3857 3858Actions 3859^^^^^^^ 3860 3861This section lists supported actions and their attributes, if any. 3862 3863- ``end``: end list of actions. 3864 3865- ``void``: no-op action. 3866 3867- ``passthru``: let subsequent rule process matched packets. 3868 3869- ``jump``: redirect traffic to group on device. 3870 3871 -

Sampling/Mirroring rules 4873~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 4874 4875Sample/Mirroring rules can be set by the following commands 4876 4877NIC-RX Sampling rule, the matched ingress packets and sent to the queue 1, 4878and 50% packets are duplicated and marked with 0x1234 and sent to queue 0. 4879 4880:: 4881 4882 testpmd> set sample_actions 0 mark id 0x1234 / queue index 0 / end 4883 testpmd> flow create 0 ingress group 1 pattern eth / end actions 4884 sample ratio 2 index 0 / queue index 1 / end 4885 4886Mirroring rule with port representors (with "transfer" attribute), the matched 4887ingress packets with encapsulation header are sent to port id 0, and also 4888mirrored the packets and sent to port id 2. 4889 4890:: 4891 4892 testpmd> set sample_actions 0 port_id id 2 / end 4893 testpmd> flow create 1 ingress transfer pattern eth / end actions 4894 sample ratio 1 index 0 / raw_encap / port_id id 0 / end 4895 4896Mirroring rule with port representors (with "transfer" attribute), the matched 4897ingress packets are sent to port id 2, and also mirrored the packets with 4898encapsulation header and sent to port id 0. 4899 4900:: 4901 4902 testpmd> set sample_actions 0 raw_encap / port_id id 0 / end 4903 testpmd> flow create 0 ingress transfer pattern eth / end actions 4904 sample ratio 1 index 0 / port_id id 2 / end 4905 4906Mirroring rule with port representors (with "transfer" attribute), the matched 4907ingress packets are sent to port id 2, and also mirrored the packets with 4908VXLAN encapsulation header and sent to port id 0. 4909 4910:: 4911 4912 testpmd> set vxlan ip-version ipv4 vni 4 udp-src 4 udp-dst 4 ip-src 127.0.0.1 4913 ip-dst 128.0.0.1 eth-src 11:11:11:11:11:11 eth-dst 22:22:22:22:22:22 4914 testpmd> set sample_actions 0 vxlan_encap / port_id

load/unload eBPF based filters. 4934 4935bpf-load 4936~~~~~~~~ 4937 4938Load an eBPF program as a callback for particular RX/TX queue:: 4939 4940 testpmd> bpf-load rx|tx (portid) (queueid) (load-flags) (bpf-prog-filename) 4941 4942The available load-flags are: 4943 4944* ``J``: use JIT generated native code, otherwise BPF interpreter will be used. 4945 4946* ``M``: assume input parameter is a pointer to rte_mbuf, otherwise assume it is a pointer to first segment's data. 4947 4948* ``-``: none. 4949 4950.. note:: 4951 4952 You'll need clang v3.7 or above to build bpf program you'd like to load 4953 4954For example: 4955 4956.. code-block:: console 4957 4958 cd examples/bpf 4959 clang -O2 -target bpf -c t1.c 4960 4961Then to load (and JIT compile) t1.o at RX queue 0, port 1: 4962 4963.. code-block:: console 4964 4965 testpmd> bpf-load rx 1 0 J ./dpdk.org/examples/bpf/t1.o 4966 4967To load (not JITed) t1.o at TX queue 0, port 0: 4968 4969.. code-block:: console 4970 4971 testpmd> bpf-load tx 0 0 - ./dpdk.org/examples/bpf/t1.o 4972 4973bpf-unload 4974~~~~~~~~~~ 4975 4976Unload previously loaded eBPF program for particular RX/TX queue:: 4977 4978 testpmd> bpf-unload rx|tx (portid) (queueid) 4979 4980For example to unload BPF filter from TX queue 0, port 0: 4981 4982.. code-block:: console 4983 4984 testpmd> bpf-unload tx 0 0 4985
