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).

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.

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.

By default, GRO is disabled for all ports. 1318 1319.. note:: 1320 1321 When enable GRO for a port, TCP/IPv4 packets received from the port 1322 will be performed GRO. After GRO, all merged packets have bad 1323 checksums, since the GRO library doesn't re-calculate checksums for 1324 the merged packets. Therefore, if users want the merged packets to 1325 have correct checksums, please select HW IP checksum calculation and 1326 HW TCP checksum calculation for the port which the merged packets are 1327 transmitted to. 1328 1329show port - gro 1330~~~~~~~~~~~~~~~ 1331 1332Display GRO configuration for a given port:: 1333 1334 testpmd> show port <port_id> gro 1335 1336set gro flush 1337~~~~~~~~~~~~~ 1338 1339Set the cycle to flush the GROed packets from reassembly tables:: 1340 1341 testpmd> set gro flush <cycles> 1342 1343When enable GRO, the csum forwarding engine performs GRO on received 1344packets, and the GROed packets are stored in reassembly tables. Users 1345can use this command to determine when the GROed packets are flushed 1346from the reassembly tables. 1347 1348The ``cycles`` is measured in GRO operation times. The csum forwarding 1349engine flushes the GROed packets from the tables every ``cycles`` GRO 1350operations. 1351 1352By default, the value of ``cycles`` is 1, which means flush GROed packets 1353from the reassembly tables as soon as one GRO operation finishes. The value 1354of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``. 1355 1356Please note that the large value of ``cycles`` may cause the poor TCP/IP 1357stack performance. Because the GROed packets are delayed to arrive the 1358stack, thus causing more duplicated ACKs and TCP retransmissions. 1359 1360set port - gso 1361~~~~~~~~~~~~~~ 1362 1363Toggle per-port GSO support in ``csum`` forwarding engine:: 1364 1365 testpmd> set port <port_id> gso on|off 1366 1367If enabled, the csum forwarding engine will perform GSO on supported IPv4 1368packets, transmitted on the given port. 1369 1370If disabled, packets transmitted on the given port will not undergo GSO. 1371By default, GSO is disabled for all ports. 1372 1373.. note:: 1374 1375 When GSO is enabled on a port, supported IPv4 packets transmitted on that 1376 port undergo GSO. Afterwards, the segmented packets are represented by 1377 multi-segment mbufs; however, the csum forwarding engine doesn't calculation 1378 of checksums for GSO'd segments in SW. As a result, if users want correct 1379 checksums in GSO segments, they should enable HW checksum calculation for 1380 GSO-enabled ports. 1381 1382 For example, HW checksum calculation for VxLAN GSO'd packets may be enabled 1383 by setting the following options in the csum forwarding engine: 1384 1385 testpmd> csum set outer_ip hw <port_id> 1386 1387 testpmd> csum set ip hw <port_id> 1388 1389 testpmd> csum set tcp hw <port_id> 1390 1391 UDP GSO is the same as IP fragmentation, which treats the UDP header 1392 as the payload and does not modify it during segmentation. That is, 1393 after UDP GSO, only the first output fragment has the original UDP 1394 header. Therefore, users need to enable HW IP checksum calculation 1395 and SW UDP checksum calculation for GSO-enabled ports, if they want 1396 correct checksums for UDP/IPv4 packets. 1397 1398set gso segsz 1399~~~~~~~~~~~~~ 1400 1401Set the maximum GSO segment size (measured in bytes), which includes the 1402packet header and the packet payload for GSO-enabled ports (global):: 1403 1404 testpmd> set gso segsz <length> 1405 1406show port - gso 1407~~~~~~~~~~~~~~~ 1408 1409Display the status of Generic Segmentation Offload for a given port:: 1410 1411 testpmd> show port <port_id> gso 1412 1413mac_addr add 1414~~~~~~~~~~~~ 1415 1416Add an alternative MAC address to a port:: 1417 1418 testpmd> mac_addr add (port_id) (XX:XX:XX:XX:XX:XX) 1419 1420mac_addr remove 1421~~~~~~~~~~~~~~~ 1422 1423Remove a MAC address from a port:: 1424 1425 testpmd> mac_addr remove (port_id) (XX:XX:XX:XX:XX:XX) 1426 1427mcast_addr add 1428~~~~~~~~~~~~~~ 1429 1430To add the multicast MAC address to/from the set of multicast addresses 1431filtered by port:: 1432 1433 testpmd> mcast_addr add (port_id) (mcast_addr) 1434 1435mcast_addr remove 1436~~~~~~~~~~~~~~~~~ 1437 1438To remove the multicast MAC address to/from the set of multicast addresses 1439filtered by port:: 1440 1441 testpmd> mcast_addr remove (port_id) (mcast_addr) 1442 1443mac_addr add (for VF) 1444~~~~~~~~~~~~~~~~~~~~~ 1445 1446Add an alternative MAC address for a VF to a port:: 1447 1448 testpmd> mac_add add port (port_id) vf (vf_id) (XX:XX:XX:XX:XX:XX) 1449 1450mac_addr set 1451~~~~~~~~~~~~ 1452 1453Set the default MAC address for a port:: 1454 1455 testpmd> mac_addr set (port_id) (XX:XX:XX:XX:XX:XX) 1456 1457mac_addr set (for VF) 1458~~~~~~~~~~~~~~~~~~~~~ 1459 1460Set the MAC address for a VF from the PF:: 1461 1462 testpmd> set vf mac addr (port_id) (vf_id) (XX:XX:XX:XX:XX:XX) 1463 1464set eth-peer 1465~~~~~~~~~~~~ 1466 1467Set the forwarding peer address for certain port:: 1468 1469 testpmd> set eth-peer (port_id) (peer_addr) 1470 1471This is equivalent to the ``--eth-peer`` command-line option. 1472 1473set port-uta 1474~~~~~~~~~~~~ 1475 1476Set the unicast hash filter(s) on/off for a port:: 1477 1478 testpmd> set port (port_id) uta (XX:XX:XX:XX:XX:XX|all) (on|off) 1479 1480set promisc 1481~~~~~~~~~~~ 1482 1483Set the promiscuous mode on for a port or for all ports. 1484In promiscuous mode packets are not dropped if they aren't for the specified MAC address:: 1485 1486 testpmd> set promisc (port_id|all) (on|off) 1487 1488set allmulti 1489~~~~~~~~~~~~ 1490 1491Set the allmulti mode for a port or for all ports:: 1492 1493 testpmd> set allmulti (port_id|all) (on|off) 1494 1495Same as the ifconfig (8) option.

specific flows or sets of flows and route them to specific queues. 3382 3383Four types of filtering are supported which are referred to as Perfect Match, Signature, Perfect-mac-vlan and 3384Perfect-tunnel filters, the match mode is set by the ``--pkt-filter-mode`` command-line parameter: 3385 3386* Perfect match filters. 3387 The hardware checks a match between the masked fields of the received packets and the programmed filters. 3388 The masked fields are for IP flow. 3389 3390* Signature filters. 3391 The hardware checks a match between a hash-based signature of the masked fields of the received packet. 3392 3393* Perfect-mac-vlan match filters. 3394 The hardware checks a match between the masked fields of the received packets and the programmed filters. 3395 The masked fields are for MAC VLAN flow. 3396 3397* Perfect-tunnel match filters. 3398 The hardware checks a match between the masked fields of the received packets and the programmed filters. 3399 The masked fields are for tunnel flow. 3400 3401* Perfect-raw-flow-type match filters. 3402 The hardware checks a match between the masked fields of the received packets and pre-loaded raw (template) packet. 3403 The masked fields are specified by input sets. 3404 3405The Flow Director filters can match the different fields for different type of packet: flow type, specific input set 3406per flow type and the flexible payload. 3407 3408The Flow Director can also mask out parts of all of these fields so that filters 3409are only applied to certain fields or parts of the fields. 3410 3411Note that for raw flow type mode the source and destination fields in the 3412raw packet buffer need to be presented in a reversed order with respect 3413to the expected received packets. 3414For example: IP source and destination addresses or TCP/UDP/SCTP 3415source and destination ports 3416 3417Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information. 3418 3419# Commands to add flow director filters of different flow types:: 3420 3421 flow_director_filter (port_id) mode IP (add|del|update) \ 3422 flow

Possible operations and 3663their general syntax are described below. They are covered in detail in the 3664following sections. 3665 3666- Check whether a flow rule can be created:: 3667 3668 flow validate {port_id} 3669 [group {group_id}] [priority {level}] [ingress] [egress] [transfer] 3670 pattern {item} [/ {item} [...]] / end 3671 actions {action} [/ {action} [...]] / end 3672 3673- Create a flow rule:: 3674 3675 flow create {port_id} 3676 [group {group_id}] [priority {level}] [ingress] [egress] [transfer] 3677 pattern {item} [/ {item} [...]] / end 3678 actions {action} [/ {action} [...]] / end 3679 3680- Destroy specific flow rules:: 3681 3682 flow destroy {port_id} rule {rule_id} [...] 3683 3684- Destroy all flow rules:: 3685 3686 flow flush {port_id} 3687 3688- Query an existing flow rule:: 3689 3690 flow query {port_id} {rule_id} {action} 3691 3692- List existing flow rules sorted by priority, filtered by group 3693 identifiers:: 3694 3695 flow list {port_id} [group {group_id}] [...] 3696 3697- Restrict ingress traffic to the defined flow rules:: 3698 3699 flow isolate {port_id} {boolean} 3700 3701- Dump internal representation information of all flows in hardware:: 3702 3703 flow dump {port_id} {output_file} 3704 3705- List and destroy aged flow rules:: 3706 3707 flow aged {port_id} [destroy] 3708 3709- Tunnel offload - create a tunnel stub:: 3710 3711 flow tunnel create {port_id} type {tunnel_type} 3712 3713- Tunnel offload - destroy a tunnel stub:: 3714 3715 flow tunnel destroy {port_id} id {tunnel_id} 3716 3717- Tunnel offload - list port tunnel stubs:: 3718 3719 flow tunnel list {port_id} 3720 3721Creating a tunnel stub for offload 3722~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 3723 3724``flow tunnel create`` setup a tunnel stub for tunnel offload flow rules:: 3725 3726 flow tunnel create {port_id} type {tunnel_type} 3727 3728If successful, it will return a tunnel stub ID usable with other commands:: 3729 3730 port [...]: flow tunnel #[...] type [...] 3731 3732Tunnel stub ID is relative to a port. 3733 3734Destroying tunnel offload stub 3735~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 3736 3737``flow tunnel destroy`` destroy port tunnel stub:: 3738 3739 flow tunnel destroy {port_id} id {tunnel_id} 3740 3741Listing tunnel offload stubs 3742~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 3743 3744``flow tunnel list`` list port tunnel offload stubs:: 3745 3746 flow tunnel list {port_id} 3747 3748Validating flow rules 3749~~~~~~~~~~~~~~~~~~~~~ 3750 3751``flow validate`` reports whether a flow rule would be accepted by the 3752underlying device in its current state but stops short of creating it.
