34========================= 35 36Where the testpmd application is started in interactive mode, (``-i|--interactive``), 37it displays a prompt that can be used to start and stop forwarding, 38configure the application, display statistics, set the Flow Director and other tasks:: 39 40 testpmd> 41 42The testpmd prompt has some, limited, readline support. 43Common bash command-line functions such as ``Ctrl+a`` and ``Ctrl+e`` to go to the start and end of the prompt line are supported 44as well as access to the command history via the up-arrow. 45 46There is also support for tab completion. 47If you type a partial command and hit ``<TAB>`` you get a list of the available completions: 48 49.. code-block:: console 50 51 testpmd> show port <TAB> 52 53 info [Mul-choice STRING]: show|clear port

`"\\"` for display purposes:: 63 64 testpmd> set flow_ctrl rx (on|off) tx (on|off) (high_water) (low_water) \ 65 (pause_time) (send_xon) (port_id) 66 67In the real ``testpmd>`` prompt these commands should be on a single line. 68 69Help Functions 70-------------- 71 72The testpmd has on-line help for the functions that are available at runtime. 73These are divided into sections and can be accessed using help, help section or help all: 74 75.. code-block:: console 76 77 testpmd> help 78 79 help control : Start and stop forwarding. 80 help display : Displaying port, stats and config information. 81 help config : Configuration information. 82 help ports : Configuring ports. 83 help registers : Reading and setting port registers. 84 help filters : Filters configuration help. 85

forwarding mode:: 251 252 testpmd> set fwd (io|mac|mac_retry|macswap|flowgen| \ 253 rxonly|txonly|csum|icmpecho) 254 255The available information categories are: 256 257* ``io``: Forwards packets "as-is" in I/O mode. 258 This is the fastest possible forwarding operation as it does not access packets data. 259 This is the default mode. 260 261* ``mac``: Changes the source and the destination Ethernet addresses of packets before forwarding them. 262 263* ``mac_retry``: Same as "mac" forwarding mode, but includes retries if the destination queue is full. 264 265* ``macswap``: MAC swap forwarding mode. 266 Swaps the source and the destination Ethernet addresses of packets before forwarding them. 267 268* ``flowgen``: Multi-flow generation mode. 269 Originates a number of flows (with varying destination IP addresses), and terminate receive traffic. 270 271* ``rxonly``: Receives packets but doesn't transmit them. 272 273* ``txonly``: Generates and transmits packets without receiving any. 274 275* ``csum``: Changes the checksum field with hardware or software methods depending on the offload flags on the packet. 276 277* ``icmpecho``: Receives a burst of packets, lookup for IMCP echo requests and, if any, send back ICMP echo replies. 278 279* ``ieee1588``: Demonstrate L2 IEEE1588 V2 PTP timestamping for RX and TX. Requires ``CONFIG_RTE_LIBRTE_IEEE1588=y``. 280 281Note: TX timestamping is only available in the "Full Featured" TX path. To force ``testpmd`` into this mode set ``--txqflags=0``. 282 283Example:: 284 285 testpmd> set fwd rxonly 286 287 Set rxonly packet forwarding mode 288 289 290read rxd 291~~~~~~~~ 292 293Display an RX descriptor for a port RX queue:: 294 295 testpmd> read rxd (port_id) (queue_id) (rxd_id) 296 297For example:: 298 299 testpmd> read rxd 0 0 4 300 0x0000000B - 0x001D0180 / 0x0000000B - 0x001D0180 301 302read txd 303~~~~~~~~ 304 305Display a TX descriptor for a port TX queue:: 306 307 testpmd> read txd (port_id) (queue_id) (txd_id) 308 309For example:: 310 311 testpmd> read txd 0 0 4 312 0x00000001 - 0x24C3C440 / 0x000F0000 - 0x2330003C 313 314 315Configuration Functions 316----------------------- 317 318The testpmd application can be configured from the runtime as well as from the command-line. 319 320This section details the available configuration functions that are available. 321 322.. note:: 323 324 Configuration changes only become active when forwarding is started/restarted. 325 326set default 327~~~~~~~~~~~ 328 329Reset forwarding to the default configuration:: 330 331 testpmd> set default 332 333set verbose 334~~~~~~~~~~~ 335 336Set the debug verbosity level:: 337 338 testpmd> set verbose (level) 339 340Currently the only available levels are 0 (silent except for error) and 1 (fully verbose). 341 342set nbport 343~~~~~~~~~~ 344 345Set the number of ports used by the application: 346 347set nbport (num) 348 349This is equivalent to the ``--nb-ports`` command-line option. 350 351set nbcore 352~~~~~~~~~~ 353 354Set the number of cores used by the application:: 355 356 testpmd> set nbcore (num) 357 358This is equivalent to the ``--nb-cores`` command-line option. 359 360.. note:: 361 362 The number of cores used must not be greater than number of ports used multiplied by the number of queues per port. 363 364set coremask 365~~~~~~~~~~~~ 366 367Set the forwarding cores hexadecimal mask:: 368 369 testpmd> set coremask (mask) 370 371This is equivalent to the ``--coremask`` command-line option. 372 373.. note:: 374 375 The master lcore is reserved for command line parsing only and cannot be masked on for packet forwarding. 376 377set portmask 378~~~~~~~~~~~~ 379 380Set the forwarding ports hexadecimal mask:: 381 382 testpmd> set portmask (mask) 383 384This is equivalent to the ``--portmask`` command-line option. 385 386set burst 387~~~~~~~~~ 388 389Set number of packets per burst:: 390 391 testpmd> set burst (num) 392 393This is equivalent to the ``--burst command-line`` option. 394 395In ``mac_retry`` forwarding mode, the transmit delay time and number of retries can also be set:: 396 397 testpmd> set burst tx delay (micrseconds) retry (num) 398 399set txpkts 400~~~~~~~~~~ 401 402Set the length of each segment of the TX-ONLY packets:: 403 404 testpmd> set txpkts (x[,y]*) 405 406Where x[,y]* represents a CSV list of values, without white space. 407 408set txsplit 409~~~~~~~~~~~ 410 411Set the split policy for the TX packets, applicable for TX-ONLY and CSUM forwarding modes:: 412 413 testpmd> set txsplit (off|on|rand) 414 415Where: 416 417* ``off`` disable packet copy & split for CSUM mode. 418 419* ``on`` split outgoing packet into multiple segments. Size of each segment 420 and number of segments per packet is determined by ``set txpkts`` command 421 (see above). 422 423* ``rand`` same as 'on', but number of segments per each packet is a random value between 1 and total number of segments. 424 425set corelist 426~~~~~~~~~~~~ 427 428Set the list of forwarding cores:: 429 430 testpmd> set corelist (x[,y]*) 431 432For example, to change the forwarding cores: 433 434.. code-block:: console 435 436 testpmd> set corelist 3,1 437 testpmd> show config fwd 438 439 io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled 440 Logical Core 3 (socket 0) forwards packets on 1 streams: 441 RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01 442 Logical Core 1 (socket 0) forwards packets on 1 streams: 443 RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00 444 445.. note:: 446 447 The cores are used in the same order as specified on the command line. 448 449set portlist 450~~~~~~~~~~~~ 451 452Set the list of forwarding ports:: 453 454 testpmd> set portlist (x[,y]*) 455 456For example, to change the port forwarding: 457 458.. code-block:: console 459 460 testpmd> set portlist 0,2,1,3 461 testpmd> show config fwd 462 463 io packet forwarding - ports=4 - cores=1 - streams=4 464 Logical Core 3 (socket 0) forwards packets on 4 streams: 465 RX P=0/Q=0 (socket 0) -> TX P=2/Q=0 (socket 0) peer=02:00:00:00:00:01 466 RX P=2/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00 467 RX P=1/Q=0 (socket 0) -> TX P=3/Q=0 (socket 0) peer=02:00:00:00:00:03 468 RX P=3/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:02 469 470vlan set strip 471~~~~~~~~~~~~~~ 472 473Set the VLAN strip on a port:: 474 475 testpmd> vlan set strip (on|off) (port_id) 476 477vlan set stripq 478~~~~~~~~~~~~~~~ 479 480Set the VLAN strip for a queue on a port:: 481 482 testpmd> vlan set stripq (on|off) (port_id,queue_id) 483 484vlan set filter 485~~~~~~~~~~~~~~~ 486 487Set the VLAN filter on a port:: 488 489 testpmd> vlan set filter (on|off) (port_id) 490 491vlan set qinq 492~~~~~~~~~~~~~ 493 494Set the VLAN QinQ (extended queue in queue) on for a port:: 495 496 testpmd> vlan set qinq (on|off) (port_id) 497 498vlan set tpid 499~~~~~~~~~~~~~ 500 501Set the inner or outer VLAN TPID for packet filtering on a port:: 502 503 testpmd> vlan set (inner|outer) tpid (value) (port_id) 504 505.. note:: 506 507 TPID value must be a 16-bit number (value <= 65536). 508 509rx_vlan add 510~~~~~~~~~~~ 511 512Add a VLAN ID, or all identifiers, to the set of VLAN identifiers filtered by port ID:: 513 514 testpmd> rx_vlan add (vlan_id|all) (port_id) 515 516.. note:: 517 518 VLAN filter must be set on that port.

them to specific queues. 1723 1724Four types of filtering are supported which are referred to as Perfect Match, Signature, Perfect-mac-vlan and 1725Perfect-tunnel filters, the match mode is set by the ``--pkt-filter-mode`` command-line parameter: 1726 1727* Perfect match filters. 1728 The hardware checks a match between the masked fields of the received packets and the programmed filters. 1729 The masked fields are for IP flow. 1730 1731* Signature filters. 1732 The hardware checks a match between a hash-based signature of the masked fields of the received packet. 1733 1734* Perfect-mac-vlan match filters. 1735 The hardware checks a match between the masked fields of the received packets and the programmed filters. 1736 The masked fields are for MAC VLAN flow. 1737 1738* Perfect-tunnel match filters. 1739 The hardware checks a match between the masked fields of the received packets and the programmed filters. 1740 The masked fields are for tunnel flow. 1741 1742The Flow Director filters can match the different fields for different type of packet: flow type, specific input set 1743per flow type and the flexible payload. 1744 1745The Flow Director can also mask out parts of all of these fields so that filters 1746are only applied to certain fields or parts of the fields. 1747 1748Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information. 1749 1750# Commands to add flow director filters of different flow types:: 1751 1752 flow_director_filter (port_id) mode IP (add|del|update) \ 1753 flow
