31Testpmd Runtime Functions
32=========================
33
34Where the testpmd application is started in interactive mode, (-i|--interactive),
35it displays a prompt that can be used to start and stop forwarding,
36configure the application, display statistics, set the Flow Director and other tasks.
37
38.. code-block:: console
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 info|stats|fdir|stat_qmap X
54        info [Mul-choice STRING]: show|clear port info|stats|fdir|stat_qmap all
55        stats [Mul-choice STRING]: show|clear port info|stats|fdir|stat_qmap X
56        stats [Mul-choice STRING]: show|clear port info|stats|fdir|stat_qmap all
57        ...

311~~~~~~~~~
312
313Set number of packets per burst:
314
315set burst (num)

321set burst tx delay (micrseconds) retry (num)
322
323set txpkts
324~~~~~~~~~~
325
326Set the length of each segment of the TX-ONLY packets:

345
346    io packet forwarding - ports=2 - cores=2 - streams=2 - NUMA support disabled
347    Logical Core 3 (socket 0) forwards packets on 1 streams:
348    RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
349    Logical Core 1 (socket 0) forwards packets on 1 streams:
350    RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00

554
555*   io: forwards packets "as-is" in I/O mode.
556    This is the fastest possible forwarding operation as it does not access packets data.
557    This is the default mode.
558
559*   mac: changes the source and the destination Ethernet addresses of packets before forwarding them.
560
561*   mac_retry: same as "mac" forwarding mode, but includes retries if the destination queue is full.
562
563*   macswap: MAC swap forwarding mode.
564    Swaps the source and the destination Ethernet addresses of packets before forwarding them.
565
566*   flowgen: multi-flow generation mode.
567    Originates a bunch of flows (varying destination IP addresses), and terminate receive traffic.
568
569*   rxonly: receives packets but doesn't transmit them.
570
571*   txonly: generates and transmits packets without receiving any.
572
573*   csum: changes the checksum field with HW or SW methods depending on the offload flags on the packet.
574
575*   icmpecho: receives a burst of packets, lookup for IMCP echo requests and, if any, send back ICMP echo replies.
576

624
625Set the allmulti mode for a port or for all ports:
626
627set allmulti (port_id|all) (on|off)

1009
1010Removes an Ethernet slave device from a Link Bonding device:
1011
1012remove bonding slave (slave id) (port id)
1013
1014For example, to remove Ethernet slave device (port 6) to a Link Bonding device (port 10).
1015
1016.. code-block:: console
1017
1018    testpmd> remove bonding slave 6 10
1019
1020set bonding mode

12705tuple_filter
1271~~~~~~~~~~~~~~~~~
1272
1273Add or delete a 5-tuple filter,
1274which consists of a 5-tuple (protocol, source and destination IP addresses, source and destination TCP/UDP/SCTP port)
1275and routes packets into one of the receive queues.
1276
12775tuple_filter (port_id) (add|del) dst_ip (dst_address) src_ip (src_address) dst_port (dst_port_value) src_port (src_port_value)
1278protocol (protocol_value) mask (mask_value) tcp_flags (tcp_flags_value) priority (prio_value) queue (queue_id)
1279
1280The available information parameters are:
1281
1282*   port_id: the port which the 5-tuple filter assigned on.
1283
1284*   dst_address: destination IP address.
1285
1286*   src_address: source IP address.
1287
1288*   dst_port_value: TCP/UDP destination port.
1289
1290*   src_port_value: TCP/UDP source port.
1291
1292*   protocol_value: L4 protocol.
1293
1294*   mask_value: participates in the match or not by bit for field above, 1b means participate
1295
1296*   tcp_flags_value: TCP control bits. The non-zero value is invalid, when the protocol_value is not set to 0x06 (TCP).
1297
1298*   prio_value: the priority of this filter.
1299
1300*   queue_id: The receive queue associated with this 5-tuple filter.
1301
1302Example, to add/remove an 5tuple filter rule:
1303
1304.. code-block:: console
1305
1306    testpmd> 5tuple_filter 0 add dst_ip 2.2.2.5 src_ip 2.2.2.4 dst_port 64 src_port 32 protocol 0x06 mask 0x1F flags 0x0 priority 3 queue 3
1307    testpmd> 5tuple_filter 0 del dst_ip 2.2.2.5 src_ip 2.2.2.4 dst_port 64 src_port 32 protocol 0x06 mask 0x1F flags 0x0 priority 3 queue 3
1308
1309syn_filter
1310~~~~~~~~~~~~~~
1311
1312By SYN filter, TCP packets whose *SYN* flag is set can be forwarded to a separate queue.
1313
1314syn_filter (port_id) (add|del) priority (high|low) queue (queue_id)
1315
1316The available information parameters are:
1317
1318*   port_id: the port which the SYN filter assigned on.
1319
1320*   high: this SYN filter has higher priority than other filters.
1321
1322*   low: this SYN filter has lower priority than other filters.
1323
1324*   queue_id: The receive queue associated with this SYN filter
1325
1326Example:
1327
1328.. code-block:: console
1329
1330    testpmd> syn_filter 0 add priority high queue 3
1331
1332flex_filter
1333~~~~~~~~~~~
1334
1335With flex filter, packets can be recognized by any arbitrary pattern within the first 128 bytes of the packet
1336and routes packets into one of the receive queues.
1337
1338flex_filter (port_id) (add|del) len (len_value) bytes (bytes_value)
1339mask (mask_value) priority (prio_value) queue (queue_id)

1343*   port_id: the port which the Flex filter is assigned on.
1344
1345*   len_value: filter length in bytes, no greater than 128.
1346
1347*   bytes_value: a string in hexadecimal, means the value the flex filter needs to match.
1348
1349*   mask_value: a string in hexadecimal, bit 1 means corresponding byte participates in the match.
1350
1351*   prio_value: the priority of this filter.
1352
1353*   queue_id: the receive queue associated with this Flex filter.
1354
1355Example:
1356
1357.. code-block:: console
1358
1359   testpmd> flex_filter 0 add len 16 bytes 0x00000000000000000000000008060000
1360        mask 000C priority 3 queue 3
1361
1362   testpmd> flex_filter 0 del len 16 bytes 0x00000000000000000000000008060000
1363        mask 000C priority 3 queue 3
1364
1365flow_director_filter
1366~~~~~~~~~~~~~~~~~~~~
1367
1368The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues.
1369
1370Two types of filtering are supported which are referred to as Perfect Match and Signature filters, the match mode
1371is set by the --pkt-filter-mode command-line parameter:
1372
1373*   Perfect match filters.
1374    The hardware checks a match between the masked fields of the received packets and the programmed filters.
1375
1376*   Signature filters.
1377    The hardware checks a match between a hash-based signature of the masked fields of the received packet.
1378
1379The Flow Director filters can match the different fields for different type of packet: flow type, specific input set
1380per flow type and the flexible payload. The Flow Director can also mask out parts of all of these fields so that filters
1381are only applied to certain fields or parts of the fields.
1382
1383Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire the information.
1384
