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

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.

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 1268packet header and the packet payload for GSO-enabled ports (global):: 1269 1270 testpmd> set gso segsz <length> 1271 1272show port - gso 1273~~~~~~~~~~~~~~~ 1274 1275Display the status of Generic Segmentation Offload for a given port:: 1276 1277 testpmd> show port <port_id> gso 1278 1279mac_addr add 1280~~~~~~~~~~~~ 1281 1282Add an alternative MAC address to a port:: 1283 1284 testpmd> mac_addr add (port_id) (XX:XX:XX:XX:XX:XX) 1285 1286mac_addr remove 1287~~~~~~~~~~~~~~~ 1288 1289Remove a MAC address from a port:: 1290 1291 testpmd> mac_addr remove (port_id) (XX:XX:XX:XX:XX:XX) 1292 1293mcast_addr add 1294~~~~~~~~~~~~~~ 1295 1296To add the multicast MAC address to/from the set of multicast addresses 1297filtered by port:: 1298 1299 testpmd> mcast_addr add (port_id) (mcast_addr) 1300 1301mcast_addr remove 1302~~~~~~~~~~~~~~~~~ 1303 1304To remove the multicast MAC address to/from the set of multicast addresses 1305filtered by port:: 1306 1307 testpmd> mcast_addr remove (port_id) (mcast_addr) 1308 1309mac_addr add (for VF) 1310~~~~~~~~~~~~~~~~~~~~~ 1311 1312Add an alternative MAC address for a VF to a port:: 1313 1314 testpmd> mac_add add port (port_id) vf (vf_id) (XX:XX:XX:XX:XX:XX) 1315 1316mac_addr set 1317~~~~~~~~~~~~ 1318 1319Set the default MAC address for a port:: 1320 1321 testpmd> mac_addr set (port_id) (XX:XX:XX:XX:XX:XX) 1322 1323mac_addr set (for VF) 1324~~~~~~~~~~~~~~~~~~~~~ 1325 1326Set the MAC address for a VF from the PF:: 1327 1328 testpmd> set vf mac addr (port_id) (vf_id) (XX:XX:XX:XX:XX:XX) 1329 1330set eth-peer 1331~~~~~~~~~~~~ 1332 1333Set the forwarding peer address for certain port:: 1334 1335 testpmd> set eth-peer (port_id) (peer_addr) 1336 1337This is equivalent to the ``--eth-peer`` command-line option. 1338 1339set port-uta 1340~~~~~~~~~~~~ 1341 1342Set the unicast hash filter(s) on/off for a port:: 1343 1344 testpmd> set port (port_id) uta (XX:XX:XX:XX:XX:XX|all) (on|off) 1345 1346set promisc 1347~~~~~~~~~~~ 1348 1349Set the promiscuous mode on for a port or for all ports. 1350In promiscuous mode packets are not dropped if they aren't for the specified MAC address:: 1351 1352 testpmd> set promisc (port_id|all) (on|off) 1353 1354set allmulti 1355~~~~~~~~~~~~ 1356 1357Set the allmulti mode for a port or for all ports:: 1358 1359 testpmd> set allmulti (port_id|all) (on|off) 1360 1361Same as the ifconfig (8) option.
