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

This command enables 838the packet send scheduling on dynamic timestamp mbuf field and configures 839timing pattern in Tx only mode. In this mode, if scheduling is enabled 840application provides timestamps in the packets being sent.

If ``inter`` parameter is zero the send scheduling 854 on timestamps is disabled (default). 855 856* ``intra`` is the delay between the packets within the burst specified 857 in the device clock units. The number of packets in the burst is defined 858 by regular burst setting. If ``intra`` parameter is zero no timestamps 859 provided in the packets excepting the first one in the burst. 860 861As the result the bursts of packet will be transmitted with specific 862delays between the packets within the burst and specific delay between 863the bursts. The rte_eth_read_clock() must be supported by the device(s) 864and is supposed to be engaged to get the current device clock value 865and provide the reference for the timestamps.

By default, GRO is disabled for all ports. 1191 1192.. note:: 1193 1194 When enable GRO for a port, TCP/IPv4 packets received from the port 1195 will be performed GRO. After GRO, all merged packets have bad 1196 checksums, since the GRO library doesn't re-calculate checksums for 1197 the merged packets. Therefore, if users want the merged packets to 1198 have correct checksums, please select HW IP checksum calculation and 1199 HW TCP checksum calculation for the port which the merged packets are 1200 transmitted to. 1201 1202show port - gro 1203~~~~~~~~~~~~~~~ 1204 1205Display GRO configuration for a given port:: 1206 1207 testpmd> show port <port_id> gro 1208 1209set gro flush 1210~~~~~~~~~~~~~ 1211 1212Set the cycle to flush the GROed packets from reassembly tables:: 1213 1214 testpmd> set gro flush <cycles> 1215 1216When enable GRO, the csum forwarding engine performs GRO on received 1217packets, and the GROed packets are stored in reassembly tables. Users 1218can use this command to determine when the GROed packets are flushed 1219from the reassembly tables. 1220 1221The ``cycles`` is measured in GRO operation times. The csum forwarding 1222engine flushes the GROed packets from the tables every ``cycles`` GRO 1223operations. 1224 1225By default, the value of ``cycles`` is 1, which means flush GROed packets 1226from the reassembly tables as soon as one GRO operation finishes. The value 1227of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``. 1228 1229Please note that the large value of ``cycles`` may cause the poor TCP/IP 1230stack performance. Because the GROed packets are delayed to arrive the 1231stack, thus causing more duplicated ACKs and TCP retransmissions. 1232 1233set port - gso 1234~~~~~~~~~~~~~~ 1235 1236Toggle per-port GSO support in ``csum`` forwarding engine:: 1237 1238 testpmd> set port <port_id> gso on|off 1239 1240If enabled, the csum forwarding engine will perform GSO on supported IPv4 1241packets, transmitted on the given port. 1242 1243If disabled, packets transmitted on the given port will not undergo GSO. 1244By default, GSO is disabled for all ports. 1245 1246.. note:: 1247 1248 When GSO is enabled on a port, supported IPv4 packets transmitted on that 1249 port undergo GSO. Afterwards, the segmented packets are represented by 1250 multi-segment mbufs; however, the csum forwarding engine doesn't calculation 1251 of checksums for GSO'd segments in SW. As a result, if users want correct 1252 checksums in GSO segments, they should enable HW checksum calculation for 1253 GSO-enabled ports. 1254 1255 For example, HW checksum calculation for VxLAN GSO'd packets may be enabled 1256 by setting the following options in the csum forwarding engine: 1257 1258 testpmd> csum set outer_ip hw <port_id> 1259 1260 testpmd> csum set ip hw <port_id> 1261 1262 testpmd> csum set tcp hw <port_id> 1263 1264 UDP GSO is the same as IP fragmentation, which treats the UDP header 1265 as the payload and does not modify it during segmentation. That is, 1266 after UDP GSO, only the first output fragment has the original UDP 1267 header. Therefore, users need to enable HW IP checksum calculation 1268 and SW UDP checksum calculation for GSO-enabled ports, if they want 1269 correct checksums for UDP/IPv4 packets. 1270 1271set gso segsz 1272~~~~~~~~~~~~~ 1273 1274Set the maximum GSO segment size (measured in bytes), which includes the 1275packet header and the packet payload for GSO-enabled ports (global):: 1276 1277 testpmd> set gso segsz <length> 1278 1279show port - gso 1280~~~~~~~~~~~~~~~ 1281 1282Display the status of Generic Segmentation Offload for a given port:: 1283 1284 testpmd> show port <port_id> gso 1285 1286mac_addr add 1287~~~~~~~~~~~~ 1288 1289Add an alternative MAC address to a port:: 1290 1291 testpmd> mac_addr add (port_id) (XX:XX:XX:XX:XX:XX) 1292 1293mac_addr remove 1294~~~~~~~~~~~~~~~ 1295 1296Remove a MAC address from a port:: 1297 1298 testpmd> mac_addr remove (port_id) (XX:XX:XX:XX:XX:XX) 1299 1300mcast_addr add 1301~~~~~~~~~~~~~~ 1302 1303To add the multicast MAC address to/from the set of multicast addresses 1304filtered by port:: 1305 1306 testpmd> mcast_addr add (port_id) (mcast_addr) 1307 1308mcast_addr remove 1309~~~~~~~~~~~~~~~~~ 1310 1311To remove the multicast MAC address to/from the set of multicast addresses 1312filtered by port:: 1313 1314 testpmd> mcast_addr remove (port_id) (mcast_addr) 1315 1316mac_addr add (for VF) 1317~~~~~~~~~~~~~~~~~~~~~ 1318 1319Add an alternative MAC address for a VF to a port:: 1320 1321 testpmd> mac_add add port (port_id) vf (vf_id) (XX:XX:XX:XX:XX:XX) 1322 1323mac_addr set 1324~~~~~~~~~~~~ 1325 1326Set the default MAC address for a port:: 1327 1328 testpmd> mac_addr set (port_id) (XX:XX:XX:XX:XX:XX) 1329 1330mac_addr set (for VF) 1331~~~~~~~~~~~~~~~~~~~~~ 1332 1333Set the MAC address for a VF from the PF:: 1334 1335 testpmd> set vf mac addr (port_id) (vf_id) (XX:XX:XX:XX:XX:XX) 1336 1337set eth-peer 1338~~~~~~~~~~~~ 1339 1340Set the forwarding peer address for certain port:: 1341 1342 testpmd> set eth-peer (port_id) (peer_addr) 1343 1344This is equivalent to the ``--eth-peer`` command-line option. 1345 1346set port-uta 1347~~~~~~~~~~~~ 1348 1349Set the unicast hash filter(s) on/off for a port:: 1350 1351 testpmd> set port (port_id) uta (XX:XX:XX:XX:XX:XX|all) (on|off) 1352 1353set promisc 1354~~~~~~~~~~~ 1355 1356Set the promiscuous mode on for a port or for all ports. 1357In promiscuous mode packets are not dropped if they aren't for the specified MAC address:: 1358 1359 testpmd> set promisc (port_id|all) (on|off) 1360 1361set allmulti 1362~~~~~~~~~~~~ 1363 1364Set the allmulti mode for a port or for all ports:: 1365 1366 testpmd> set allmulti (port_id|all) (on|off) 1367 1368Same as the ifconfig (8) option.
