It is not currently possible to specify a specific source Ethernet address. 306 307* ``macswap``: MAC swap forwarding mode. 308 Swaps the source and the destination Ethernet addresses of packets before forwarding them. 309 310* ``flowgen``: Multi-flow generation mode. 311 Originates a number of flows (with varying destination IP addresses), and terminate receive traffic. 312 313* ``rxonly``: Receives packets but doesn't transmit them. 314 315* ``txonly``: Generates and transmits packets without receiving any. 316 317* ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet. 318 319* ``icmpecho``: Receives a burst of packets, lookup for IMCP echo requests and, if any, send back ICMP echo replies. 320 321* ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX. Requires ``CONFIG_RTE_LIBRTE_IEEE1588=y``. 322 323* ``tm``: Traffic Management forwarding mode 324 Demonstrates the use of ethdev traffic management APIs and softnic PMD for 325 QoS traffic management. In this mode, 5-level hierarchical QoS scheduler is 326 available as an default option that can be enabled through CLI. The user can 327 also modify the default hierarchy or specify the new hierarchy through CLI for 328 implementing QoS scheduler.

By default, GRO is disabled for all ports. 961 962.. note:: 963 964 When enable GRO for a port, TCP/IPv4 packets received from the port 965 will be performed GRO. After GRO, all merged packets have bad 966 checksums, since the GRO library doesn't re-calculate checksums for 967 the merged packets. Therefore, if users want the merged packets to 968 have correct checksums, please select HW IP checksum calculation and 969 HW TCP checksum calculation for the port which the merged packets are 970 transmitted to. 971 972show port - gro 973~~~~~~~~~~~~~~~ 974 975Display GRO configuration for a given port:: 976 977 testpmd> show port <port_id> gro 978 979set gro flush 980~~~~~~~~~~~~~ 981 982Set the cycle to flush the GROed packets from reassembly tables:: 983 984 testpmd> set gro flush <cycles> 985 986When enable GRO, the csum forwarding engine performs GRO on received 987packets, and the GROed packets are stored in reassembly tables. Users 988can use this command to determine when the GROed packets are flushed 989from the reassembly tables. 990 991The ``cycles`` is measured in GRO operation times. The csum forwarding 992engine flushes the GROed packets from the tables every ``cycles`` GRO 993operations. 994 995By default, the value of ``cycles`` is 1, which means flush GROed packets 996from the reassembly tables as soon as one GRO operation finishes. The value 997of ``cycles`` should be in the range of 1 to ``GRO_MAX_FLUSH_CYCLES``. 998 999Please note that the large value of ``cycles`` may cause the poor TCP/IP 1000stack performance. Because the GROed packets are delayed to arrive the 1001stack, thus causing more duplicated ACKs and TCP retransmissions. 1002 1003set port - gso 1004~~~~~~~~~~~~~~ 1005 1006Toggle per-port GSO support in ``csum`` forwarding engine:: 1007 1008 testpmd> set port <port_id> gso on|off 1009 1010If enabled, the csum forwarding engine will perform GSO on supported IPv4 1011packets, transmitted on the given port. 1012 1013If disabled, packets transmitted on the given port will not undergo GSO. 1014By default, GSO is disabled for all ports. 1015 1016.. note:: 1017 1018 When GSO is enabled on a port, supported IPv4 packets transmitted on that 1019 port undergo GSO. Afterwards, the segmented packets are represented by 1020 multi-segment mbufs; however, the csum forwarding engine doesn't calculation 1021 of checksums for GSO'd segments in SW.

2702 2703 2704.. _testpmd_flow_director: 2705 2706flow_director_filter 2707~~~~~~~~~~~~~~~~~~~~ 2708 2709The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues. 2710 2711Four types of filtering are supported which are referred to as Perfect Match, Signature, Perfect-mac-vlan and 2712Perfect-tunnel filters, the match mode is set by the ``--pkt-filter-mode`` command-line parameter: 2713 2714* Perfect match filters. 2715 The hardware checks a match between the masked fields of the received packets and the programmed filters. 2716 The masked fields are for IP flow. 2717 2718* Signature filters. 2719 The hardware checks a match between a hash-based signature of the masked fields of the received packet. 2720 2721* Perfect-mac-vlan match filters. 2722 The hardware checks a match between the masked fields of the received packets and the programmed filters. 2723 The masked fields are for MAC VLAN flow. 2724 2725* Perfect-tunnel match filters. 2726 The hardware checks a match between the masked fields of the received packets and the programmed filters. 2727 The masked fields are for tunnel flow. 2728 2729* Perfect-raw-flow-type match filters. 2730 The hardware checks a match between the masked fields of the received packets and pre-loaded raw (template) packet. 2731 The masked fields are specified by input sets. 2732 2733The Flow Director filters can match the different fields for different type of packet: flow type, specific input set 2734per flow type and the flexible payload. 2735 2736The Flow Director can also mask out parts of all of these fields so that filters 2737are only applied to certain fields or parts of the fields. 2738 2739Note that for raw flow type mode the source and destination fields in the 2740raw packet buffer need to be presented in a reversed order with respect 2741to the expected received packets. 2742For example: IP source and destination addresses or TCP/UDP/SCTP 2743source and destination ports 2744 2745Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information. 2746 2747# Commands to

Possible operations and 2991their general syntax are described below. They are covered in detail in the 2992following sections. 2993 2994- Check whether a flow rule can be created:: 2995 2996 flow validate {port_id} 2997 [group {group_id}] [priority {level}] [ingress] [egress] 2998 pattern {item} [/ {item} [...]] / end 2999 actions {action} [/ {action} [...]] / end 3000 3001- Create a flow rule:: 3002 3003 flow create {port_id} 3004 [group {group_id}] [priority {level}] [ingress] [egress] 3005 pattern {item} [/ {item} [...]] / end 3006 actions {action} [/ {action} [...]] / end 3007 3008- Destroy specific flow rules:: 3009 3010 flow destroy {port_id} rule {rule_id} [...] 3011 3012- Destroy all flow rules:: 3013 3014 flow flush {port_id} 3015 3016- Query an existing flow rule:: 3017 3018 flow query {port_id} {rule_id} {action} 3019 3020- List existing flow rules sorted by priority, filtered by group 3021 identifiers:: 3022 3023 flow list {port_id} [group {group_id}] [...] 3024 3025- Restrict ingress traffic to the defined flow rules:: 3026 3027 flow isolate {port_id} {boolean} 3028 3029Validating flow rules 3030~~~~~~~~~~~~~~~~~~~~~ 3031 3032``flow validate`` reports whether a flow rule would be accepted by the 3033underlying device in its current state but stops short of creating it.

All item properties can be specified 3164in a similar fashion. 3165 3166The ``is`` token means that the subsequent value must be matched exactly, 3167and assigns ``spec`` and ``mask`` fields in ``struct rte_flow_item`` 3168accordingly. Possible assignment tokens are: 3169 3170- ``is``: match value perfectly (with full bit-mask). 3171- ``spec``: match value according to configured bit-mask. 3172- ``last``: specify upper bound to establish a range. 3173- ``mask``: specify bit-mask with relevant bits set to one. 3174- ``prefix``: generate bit-mask from a prefix length. 3175 3176These yield identical results:: 3177 3178 ipv4 src is 10.1.1.1 3179 3180:: 3181 3182 ipv4 src spec 10.1.1.1 src mask 255.255.255.255 3183 3184:: 3185 3186 ipv4 src spec 10.1.1.1 src prefix 32 3187 3188:: 3189 3190 ipv4 src is 10.1.1.1 src last 10.1.1.1 # range with a single value 3191 3192:: 3193 3194 ipv4 src is 10.1.1.1 src last 0 # 0 disables range 3195 3196Inclusive ranges can be defined with ``last``:: 3197 3198 ipv4 src is 10.1.1.1 src last 10.2.3.4 # 10.1.1.1 to 10.2.3.4 3199 3200Note that ``mask`` affects both ``spec`` and ``last``:: 3201 3202 ipv4 src is 10.1.1.1 src last 10.2.3.4 src mask 255.255.0.0 3203 # matches 10.1.0.0 to 10.2.255.255 3204 3205Properties can be modified multiple times:: 3206 3207 ipv4 src is 10.1.1.1 src is 10.1.2.3 src is 10.2.3.4 # matches 10.2.3.4 3208 3209:: 3210 3211 ipv4 src is 10.1.1.1 src prefix 24 src prefix 16 # matches 10.1.0.0/16 3212 3213Pattern items 3214^^^^^^^^^^^^^ 3215 3216This section lists supported pattern items and their attributes, if any. 3217 3218- ``end``: end list of pattern items. 3219 3220- ``void``: no-op pattern item. 3221 3222- ``invert``: perform actions when pattern does not match. 3223 3224- ``any``: match any protocol for the current layer. 3225 3226 -
