312 * This command is used to start or stop a packet capture, or show
313 * the status of packet capture. Note that both "pcap rx trace" and
314 * "pcap tx trace" are implemented. The command syntax is identical,
315 * simply substitute rx for tx as needed.
317 * This command has the following optional parameters:
319 * - <b>on|off</b> - Used to start or stop a packet capture.
321 * - <b>max <nn></b> - Depth of local buffer. Once '<em>nn</em>' number
322 * of packets have been received, buffer is flushed to file. Once another
323 * '<em>nn</em>' number of packets have been received, buffer is flushed
324 * to file, overwriting previous write. If not entered, value defaults
325 * to 100. Can only be updated if packet capture is off.
327 * - <b>intfc <interface>|any</b> - Used to specify a given interface,
328 * or use '<em>any</em>' to run packet capture on all interfaces.
329 * '<em>any</em>' is the default if not provided. Settings from a previous
330 * packet capture are preserved, so '<em>any</em>' can be used to reset
331 * the interface setting.
333 * - <b>file <name></b> - Used to specify the output filename. The file will
334 * be placed in the '<em>/tmp</em>' directory, so only the filename is
335 * supported. Directory should not be entered. If file already exists, file
336 * will be overwritten. If no filename is provided, '<em>/tmp/vpe.pcap</em>'
337 * will be used. Can only be updated if packet capture is off.
339 * - <b>status</b> - Displays the current status and configured attributes
340 * associated with a packet capture. If packet capture is in progress,
341 * '<em>status</em>' also will return the number of packets currently in
342 * the local buffer. All additional attributes entered on command line
343 * with '<em>status</em>' will be ignored and not applied.
346 * Example of how to display the status of a tx packet capture when off:
347 * @cliexstart{pcap tx trace status}
348 * max is 100, for any interface to file /tmp/vpe.pcap
349 * pcap tx capture is off...
351 * Example of how to start a tx packet capture:
352 * @cliexstart{pcap tx trace on max 35 intfc GigabitEthernet0/8/0 file vppTest.pcap}
353 * pcap tx capture on...
355 * Example of how to display the status of a tx packet capture in progress:
356 * @cliexstart{pcap tx trace status}
357 * max is 35, for interface GigabitEthernet0/8/0 to file /tmp/vppTest.pcap
358 * pcap tx capture is on: 20 of 35 pkts...
360 * Example of how to stop a tx packet capture:
361 * @cliexstart{vppctl pcap tx trace off}
362 * captured 21 pkts...
363 * saved to /tmp/vppTest.pcap...

1400 * - <b>id subport|pipe|tc</b> - Classification occurs across three fields.
1401 * This parameter indicates which of the three masks are being configured. Legacy
1402 * code used 0-2 to represent these three fields, so 0-2 is still accepted.
1403 * - <b>subport|0</b> - Currently only one subport is supported, so only
1404 * an empty mask is supported for the subport classification.
1405 * - <b>pipe|1</b> - Currently, 4096 pipes per subport are supported, so a
1406 * 12-bit mask should be configure to map to the 0-4095 pipes.
1407 * - <b>tc|2</b> - The translation table (see '<em>set dpdk interface hqos
1408 * tctbl</em>' command) maps each value (0-63) into one of the 4 traffic classes
1409 * per pipe. A 6-bit mask should be configure to map this field to a traffic class.
1411 * - <b>offset <n></b> - Offset in the packet to apply the 64-bit mask for classification.
1412 * The offset should be on an 8-byte boundary (0,8,16,24..).
1414 * - <b>mask <hex-mask></b> - 64-bit mask to apply to packet at the given '<em>offset</em>'.
1415 * Bits must be contiguous and should not include '<em>0x</em>'.
1417 * The default values for the '<em>pktfield</em>' assumes Ethernet/IPv4/UDP packets with
1418 * no VLAN. Adjust based on expected packet format and desired classification field.
1419 * - '<em>subport</em>' is always empty (offset 0 mask 0000000000000000)
