The user may specify a target destination Ethernet address via the 'eth-peer' or 333 'eth-peers-configfile' command-line options. It is not currently possible to specify a specific source Ethernet address. 334 335* ``macswap``: MAC swap forwarding mode. 336 Swaps the source and the destination Ethernet addresses of packets before forwarding them. 337 338* ``flowgen``: Multi-flow generation mode. 339 Originates a number of flows (with varying destination IP addresses), and terminate receive traffic. 340 341* ``rxonly``: Receives packets but doesn't transmit them. 342 343* ``txonly``: Generates and transmits packets without receiving any. 344 345* ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet. 346 347* ``icmpecho``: Receives a burst of packets, lookup for ICMP echo requests and, if any, send back ICMP echo replies. 348 349* ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX. 350 351* ``noisy``: Noisy neighbor simulation. 352 Simulate more realistic behavior of a guest machine engaged in receiving 353 and sending packets performing Virtual Network Function (VNF). 354 355* ``5tswap``: Swap the source and destination of L2,L3,L4 if they exist. 356 357 L2 swaps the source address and destination address of Ethernet, as same as ``macswap``. 358 359 L3 swaps the source address and destination address of IP (v4 and v6). 360 361 L4 swaps the source port and destination port of transport layer (TCP and UDP). 362 363* ``shared-rxq``: Receive only for shared Rx queue. 364 Resolve packet source port from mbuf and update stream statistics accordingly. 365 366* ``recycle_mbufs``: Recycle Tx queue used mbufs for Rx queue mbuf ring. 367 This mode uses fast path mbuf recycle feature and forwards packets in I/O mode. 368 369Example:: 370 371 testpmd> set fwd rxonly 372 373 Set rxonly packet forwarding mode

This command enables 847the packet send scheduling on dynamic timestamp mbuf field and configures 848timing pattern in Tx only mode. In this mode, if scheduling is enabled 849application provides timestamps in the packets being sent. It is possible 850to configure delay (in unspecified device clock units) between bursts 851and between the packets within the burst:: 852 853 testpmd> set txtimes (inter),(intra) 854 855where: 856 857* ``inter`` is the delay between the bursts in the device clock units. 858 If ``intra`` is zero, this is the time between the beginnings of the 859 first packets in the neighbour bursts, if ``intra`` is not zero, 860 ``inter`` specifies the time between the beginning of the first packet 861 of the current burst and the beginning of the last packet of the 862 previous burst. If ``inter`` parameter is zero the send scheduling 863 on timestamps is disabled (default). 864 865* ``intra`` is the delay between the packets within the burst specified 866 in the device clock units. The number of packets in the burst is defined 867 by regular burst setting. If ``intra`` parameter is zero no timestamps 868 provided in the packets excepting the first one in the burst. 869 870As the result the bursts of packet will be transmitted with specific 871delays between the packets within the burst and specific delay between 872the bursts. The rte_eth_read_clock() must be supported by the device(s) 873and is supposed to be engaged to get the current device clock value 874and provide the reference for the timestamps. If there is no supported 875rte_eth_read_clock() there will be no send scheduling provided on the port. 876 877set txsplit 878~~~~~~~~~~~ 879 880Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes:: 881 882 testpmd> set txsplit (off|on|rand) 883 884Where: 885 886* ``off`` disable packet copy & split for CSUM mode. 887 888* ``on`` split outgoing packet into multiple segments.

By default, GRO is disabled for all ports. 1200 1201.. note:: 1202 1203 When enable GRO for a port, TCP/IPv4 packets received from the port 1204 will be performed GRO. After GRO, all merged packets have bad 1205 checksums, since the GRO library doesn't re-calculate checksums for 1206 the merged packets. Therefore, if users want the merged packets to 1207 have correct checksums, please select HW IP checksum calculation and 1208 HW TCP checksum calculation for the port which the merged packets are 1209 transmitted to. 1210 1211show port - gro 1212~~~~~~~~~~~~~~~ 1213 1214Display GRO configuration for a given port:: 1215 1216 testpmd> show port <port_id> gro 1217 1218set gro flush 1219~~~~~~~~~~~~~ 1220 1221Set the cycle to flush the GROed packets from reassembly tables:: 1222 1223 testpmd> set gro flush <cycles> 1224 1225When enable GRO, the csum forwarding engine performs GRO on received 1226packets, and the GROed packets are stored in reassembly tables. Users 1227can use this command to determine when the GROed packets are flushed 1228from the reassembly tables. 1229 1230The ``cycles`` is measured in GRO operation times. The csum forwarding 1231engine flushes the GROed packets from the tables every ``cycles`` GRO 1232operations. 1233 1234By default, the value of ``cycles`` is 1, which means flush GROed packets 1235from the reassembly tables as soon as one GRO operation finishes. The value 1236of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``. 1237 1238Please note that the large value of ``cycles`` may cause the poor TCP/IP 1239stack performance. Because the GROed packets are delayed to arrive the 1240stack, thus causing more duplicated ACKs and TCP retransmissions. 1241 1242set port - gso 1243~~~~~~~~~~~~~~ 1244 1245Toggle per-port GSO support in ``csum`` forwarding engine:: 1246 1247 testpmd> set port <port_id> gso on|off 1248 1249If enabled, the csum forwarding engine will perform GSO on supported IPv4 1250packets, transmitted on the given port. 1251 1252If disabled, packets transmitted on the given port will not undergo GSO. 1253By default, GSO is disabled for all ports. 1254 1255.. note:: 1256 1257 When GSO is enabled on a port, supported IPv4 packets transmitted on that 1258 port undergo GSO. Afterwards, the segmented packets are represented by 1259 multi-segment mbufs; however, the csum forwarding engine doesn't calculation 1260 of checksums for GSO'd segments in SW. As a result, if users want correct 1261 checksums in GSO segments, they should enable HW checksum calculation for 1262 GSO-enabled ports. 1263 1264 For example, HW checksum calculation for VxLAN GSO'd packets may be enabled 1265 by setting the following options in the csum forwarding engine: 1266 1267 testpmd> csum set outer_ip hw <port_id> 1268 1269 testpmd> csum set ip hw <port_id> 1270 1271 testpmd> csum set tcp hw <port_id> 1272 1273 UDP GSO is the same as IP fragmentation, which treats the UDP header 1274 as the payload and does not modify it during segmentation.

See `Flow rules management`_. 2929 2930.. _testpmd_rte_flow: 2931 2932Flow rules management 2933--------------------- 2934 2935Control of the generic flow API (*rte_flow*) is fully exposed through the 2936``flow`` command (configuration, validation, creation, destruction, queries 2937and operation modes). 2938 2939Considering *rte_flow* overlaps with all `Filter Functions`_, using both 2940features simultaneously may cause undefined side-effects and is therefore 2941not recommended. 2942 2943``flow`` syntax 2944~~~~~~~~~~~~~~~ 2945 2946Because the ``flow`` command uses dynamic tokens to handle the large number 2947of possible flow rules combinations, its behavior differs slightly from 2948other commands, in particular: 2949 2950- Pressing *?* or the *<tab>* key displays contextual help for the current 2951 token, not that of the entire command. 2952 2953- Optional and repeated parameters are supported (provided they are listed 2954 in the contextual help). 2955 2956The first parameter stands for the operation mode. Possible operations and 2957their general syntax are described below. They are covered in detail in the 2958following sections. 2959 2960- Get info about flow engine:: 2961 2962 flow info {port_id} 2963 2964- Configure flow engine:: 2965 2966 flow configure {port_id} 2967 [queues_number {number}] [queues_size {size}] 2968 [counters_number {number}] 2969 [aging_counters_number {number}] 2970 [meters_number {number}] [flags {number}] 2971 2972- Create a pattern template:: 2973 2974 flow pattern_template {port_id} create [pattern_template_id {id}] 2975 [relaxed {boolean}] [ingress] [egress] [transfer] 2976 template {item} [/ {item} [...]] / end 2977 2978- Destroy a pattern template:: 2979 2980 flow pattern_template {port_id} destroy pattern_template {id} [...] 2981 2982- Create an actions template:: 2983 2984 flow actions_template {port_id} create [actions_template_id {id}] 2985 [ingress] [egress] [transfer] 2986 template {action} [/ {action} [...]] / end 2987 mask {action} [/ {action} [...]] / end 2988 2989- Destroy an actions template:: 2990 2991 flow actions_template {port_id} destroy actions_template {id} [...] 2992 2993- Create a table:: 2994 2995 flow table {port_id} create 2996 [table_id {id}] 2997 [group {group_id}] [priority {level}] [ingress] [egress] [transfer] 2998 rules_number {number} 2999 pattern_template {pattern_template_id} 3000 actions_template {actions_template_id} 3001 3002- Destroy a table:: 3003 3004 flow table {port_id} destroy table {id} [...] 3005 3006- Check whether a flow rule can be created:: 3007 3008 flow validate {port_id} 3009 [group {group_id}] [priority {level}] [ingress] [egress] [transfer] 3010 pattern {item} [/ {item} [...]] / end 3011 actions {action} [/ {action} [...]] / end 3012 3013- Enqueue creation of a flow rule:: 3014 3015 flow queue {port_id} create {queue_id} 3016 [postpone {boolean}] template_table {table_id} 3017 pattern_template {pattern_template_index} 3018 actions_template {actions_template_index} 3019 pattern {item} [/ {item} [...]] / end 3020 actions {action} [/ {action} [...]] / end 3021 3022- Enqueue destruction of specific flow rules:: 3023 3024 flow queue {port_id} destroy {queue_id} 3025 [postpone {boolean}] rule {rule_id} [...] 3026 3027- Push enqueued operations:: 3028 3029 flow push {port_id} queue {queue_id} 3030 3031- Pull all operations results from a queue:: 3032 3033 flow pull {port_id} queue {queue_id} 3034 3035- Create a flow rule:: 3036 3037 flow create {port_id} 3038 [group {group_id}] [priority {level}] [ingress] [egress] 3039 [transfer] [tunnel_set {tunnel_id}] [tunnel_match {tunnel_id}] 3040 [user_id {user_id}] pattern {item} [/ {item} [...]] / end 3041 actions {action} [/ {action} [...]] / end 3042 3043- Destroy specific flow rules:: 3044 3045 flow destroy {port_id} rule {rule_id} [...] [user_id] 3046 3047- Destroy all flow rules:: 3048 3049 flow flush {port_id} 3050 3051- Query an existing flow rule:: 3052 3053 flow query {port_id} {rule_id} {action} [user_id] 3054 3055- List existing flow rules sorted by priority, filtered by group 3056 identifiers:: 3057 3058 flow list {port_id} [group {group_id}] [...] 3059 3060- Restrict ingress traffic to the defined flow rules:: 3061 3062 flow isolate {port_id} {boolean} 3063 3064- Dump internal representation information of all flows in hardware:: 3065 3066 flow dump {port_id} all {output_file} [user_id] 3067 3068 for one flow:: 3069 3070 flow dump {port_id} rule {rule_id} {output_file} [user_id] 3071 3072- List and destroy aged flow rules:: 3073 3074 flow aged {port_id} [destroy] 3075 3076- Enqueue list and destroy aged flow rules:: 3077 3078 flow queue {port_id} aged {queue_id} [destroy] 3079 3080- Tunnel offload - create a tunnel stub:: 3081 3082 flow tunnel create {port_id} type {tunnel_type} 3083 3084- Tunnel offload - destroy a tunnel stub:: 3085 3086 flow tunnel destroy {port_id} id {tunnel_id} 3087 3088- Tunnel offload - list port tunnel stubs:: 3089 3090 flow tunnel list {port_id} 3091 3092Retrieving info about flow management engine 3093~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 3094 3095``flow info`` retrieves info on pre-configurable resources in the underlying 3096device to give a hint of possible values for flow engine configuration. 3097 3098``rte_flow_info_get()``:: 3099 3100 flow info {port_id} 3101 3102If successful, it will show:: 3103 3104 Flow engine resources on port #[...]: 3105 Number of queues: #[...] 3106 Size of queues: #[...] 3107 Number of counters: #[...] 3108 Number of aging objects: #[...] 3109 Number of meters: #[...] 3110 3111Otherwise it will show an error message of the form:: 3112 3113 Caught error type [...] ([...]): [...] 3114 3115Configuring flow management engine 3116~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 3117 3118``flow configure`` pre-allocates all the needed resources in the underlying 3119device to be used later at the flow creation.
