279 * This command is used to start or stop a packet capture, or show
280 * the status of packet capture.
282 * This command has the following optional parameters:
284 * - <b>on|off</b> - Used to start or stop a packet capture.
286 * - <b>max <nn></b> - Depth of local buffer. Once '<em>nn</em>' number
287 * of packets have been received, buffer is flushed to file. Once another
288 * '<em>nn</em>' number of packets have been received, buffer is flushed
289 * to file, overwriting previous write. If not entered, value defaults
290 * to 100. Can only be updated if packet capture is off.
292 * - <b>intfc <interface>|any</b> - Used to specify a given interface,
293 * or use '<em>any</em>' to run packet capture on all interfaces.
294 * '<em>any</em>' is the default if not provided. Settings from a previous
295 * packet capture are preserved, so '<em>any</em>' can be used to reset
296 * the interface setting.
298 * - <b>file <name></b> - Used to specify the output filename. The file will
299 * be placed in the '<em>/tmp</em>' directory, so only the filename is
300 * supported. Directory should not be entered. If file already exists, file
301 * will be overwritten. If no filename is provided, '<em>/tmp/vpe.pcap</em>'
302 * will be used. Can only be updated if packet capture is off.
304 * - <b>status</b> - Displays the current status and configured attributes
305 * associated with a packet capture. If packet capture is in progress,
306 * '<em>status</em>' also will return the number of packets currently in
307 * the local buffer. All additional attributes entered on command line
308 * with '<em>status</em>' will be ingnored and not applied.
311 * Example of how to display the status of a tx packet capture when off:
312 * @cliexstart{pcap tx trace status}
313 * max is 100, for any interface to file /tmp/vpe.pcap
314 * pcap tx capture is off...
316 * Example of how to start a tx packet capture:
317 * @cliexstart{pcap tx trace on max 35 intfc GigabitEthernet0/8/0 file vppTest.pcap}
318 * pcap tx capture on...
320 * Example of how to display the status of a tx packet capture in progress:

322 * max is 35, for interface GigabitEthernet0/8/0 to file /tmp/vppTest.pcap

327 * captured 21 pkts...

1445 * - <b>id subport|pipe|tc</b> - Classification occurs across three fields.
1446 * This parameter indicates which of the three masks are being configured. Legacy
1447 * code used 0-2 to represent these three fields, so 0-2 is still accepted.
1448 * - <b>subport|0</b> - Currently only one subport is supported, so only
1449 * an empty mask is supported for the subport classification.
1450 * - <b>pipe|1</b> - Currently, 4096 pipes per subport are supported, so a
1451 * 12-bit mask should be configure to map to the 0-4095 pipes.
1452 * - <b>tc|2</b> - The translation table (see '<em>set dpdk interface hqos
1453 * tctbl</em>' command) maps each value (0-63) into one of the 4 traffic classes
1454 * per pipe. A 6-bit mask should be configure to map this field to a traffic class.
1456 * - <b>offset <n></b> - Offset in the packet to apply the 64-bit mask for classification.
1457 * The offset should be on an 8-byte boundary (0,8,16,24..).
1459 * - <b>mask <hex-mask></b> - 64-bit mask to apply to packet at the given '<em>offset</em>'.
1460 * Bits must be contiguous and should not include '<em>0x</em>'.
1462 * The default values for the '<em>pktfield</em>' assumes Ethernet/IPv4/UDP packets with
1463 * no VLAN. Adjust based on expected packet format and desired classification field.
1464 * - '<em>subport</em>' is always empty (offset 0 mask 0000000000000000)
1465 * - By default, '<em>pipe</em>' maps to the UDP payload bits 12 .. 23 (offset 40
1466 * mask 0000000fff000000)
1467 * - By default, '<em>tc</em>' maps to the DSCP field in IP header (offset 48 mask
1471 * Example of how modify the '<em>pipe</em>' classification filter to match VLAN:
1472 * @cliexcmd{set dpdk interface hqos pktfield GigabitEthernet0/8/0 id pipe offset 8 mask 0000000000000FFF}
