591 : *
592 : * The following subinterface syntax is supported. The first two are for
593 : * backwards compatability:
594 : *
595 : * <intf-name> <id>
596 : * - a subinterface with the name <intf-name>.<id>. The subinterface
597 : * is a single dot1q vlan with vlan id <id> and exact-match semantics.
598 : *
599 : * <intf-name> <min_id>-<max_id>
600 : * - a set of the above subinterfaces, repeating for each id
601 : * in the range <min_id> to <max_id>
602 : *
603 : * In the following, exact-match semantics (i.e. the number of vlan tags on the
604 : * packet must match the number of tags in the configuration) are used only if
605 : * the keyword exact-match is present. Non-exact match is the default.
606 : *
607 : * <intf-name> <id> dot1q <outer_id> [exact-match]
608 : * - a subinterface with the name <intf-name>.<id>. The subinterface
609 : * is a single dot1q vlan with vlan id <outer_id>.
610 : *
611 : * <intf-name> <id> dot1q any [exact-match]
612 : * - a subinterface with the name <intf-name>.<id>. The subinterface
613 : * is a single dot1q vlan with any vlan id.
614 : *
615 : * <intf-name> <id> dot1q <outer_id> inner-dot1q <inner_id> [exact-match]
616 : * - a subinterface with the name <intf-name>.<id>. The subinterface
617 : * is a double dot1q vlan with outer vlan id <outer_id> and inner vlan id
618 : * <inner_id>.
619 : *
620 : * <intf-name> <id> dot1q <outer_id> inner-dot1q any [exact-match]
621 : * - a subinterface with the name <intf-name>.<id>. The subinterface
622 : * is a double dot1q vlan with outer vlan id <id> and any inner vlan id.
623 : *
624 : * <intf-name> <id> dot1q any inner-dot1q any [exact-match]
625 : *
626 : * - a subinterface with the name <intf-name>.<id>. The subinterface
627 : * is a double dot1q vlan with any outer vlan id and any inner vlan id.
628 : *
629 : * For each of the above CLI, there is a duplicate that uses the keyword
630 : * "dot1ad" in place of the first "dot1q". These interfaces use ethertype
631 : * 0x88ad in place of 0x8100 for the outer ethertype. Note that for double-
632 : * tagged packets the inner ethertype is always 0x8100. Also note that
633 : * the dot1q and dot1ad naming spaces are independent, so it is legal to
634 : * have both "Gig3/0/0.1 dot1q 100" and "Gig3/0/0.2 dot1ad 100". For example:
635 : *
636 : * <intf-name> <id> dot1ad <outer_id> inner-dot1q <inner_id> [exact-match]
637 : * - a subinterface with the name <intf-name>.<id>. The subinterface
638 : * is a double dot1ad vlan with outer vlan id <outer_id> and inner vlan
639 : * id <inner_id>.
640 : *
641 : * <intf-name> <id> untagged
642 : * - a subinterface with the name <intf-name>.<id>. The subinterface
643 : * has no vlan tags. Only one can be specified per interface.
644 : *
645 : * <intf-name> <id> default
646 : * - a subinterface with the name <intf-name>.<id>. This is associated
647 : * with a packet that did not match any other configured subinterface
648 : * on this interface. Only one can be specified per interface.

829 : * This command is used to add VLAN IDs to interfaces, also known as subinterfaces.
830 : * The primary input to this command is the '<em>interface</em>' and '<em>subId</em>'
831 : * (subinterface Id) parameters. If no additional VLAN ID is provide, the VLAN ID is
832 : * assumed to be the '<em>subId</em>'. The VLAN ID and '<em>subId</em>' can be different,
833 : * but this is not recommended.
834 : *
835 : * This command has several variations:
836 : * - <b>create sub-interfaces <interface> <subId></b> - Create a subinterface to
837 : * process packets with a given 802.1q VLAN ID (same value as the '<em>subId</em>').
838 : *
839 : * - <b>create sub-interfaces <interface> <subId> default</b> - Adding the
840 : * '<em>default</em>' parameter indicates that packets with VLAN IDs that do not
841 : * match any other subinterfaces should be sent to this subinterface.
842 : *
843 : * - <b>create sub-interfaces <interface> <subId> untagged</b> - Adding the
844 : * '<em>untagged</em>' parameter indicates that packets no VLAN IDs should be sent
845 : * to this subinterface.
846 : *
847 : * - <b>create sub-interfaces <interface> <subId>-<subId></b> - Create a range of
848 : * subinterfaces to handle a range of VLAN IDs.
849 : *
850 : * - <b>create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any [exact-match]</b> -
851 : * Use this command to specify the outer VLAN ID, to either be explicit or to make the
852 : * VLAN ID different from the '<em>subId</em>'.
853 : *
854 : * - <b>create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any inner-dot1q
855 : * <vlanId>|any [exact-match]</b> - Use this command to specify the outer VLAN ID and
856 : * the inner VLAN ID.
857 : *
858 : * When '<em>dot1q</em>' or '<em>dot1ad</em>' is explicitly entered, subinterfaces
859 : * can be configured as either exact-match or non-exact match. Non-exact match is the CLI
860 : * default. If '<em>exact-match</em>' is specified, packets must have the same number of
861 : * VLAN tags as the configuration. For non-exact-match, packets must at least that number
862 : * of tags. L3 (routed) interfaces must be configured as exact-match. L2 interfaces are
863 : * typically configured as non-exact-match. If '<em>dot1q</em>' or '<em>dot1ad</em>' is NOT
864 : * entered, then the default behavior is exact-match.
865 : *
866 : * Use the '<em>show interface</em>' command to display all subinterfaces.

868 : * @cliexpar

870 : * Example of how to create a VLAN subinterface 11 to process packets on 802.1q VLAN ID 11:
871 : * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11}
872 : *
873 : * The previous example is shorthand and is equivalent to:
874 : * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 11 exact-match}
875 : *
876 : *
877 : * Example of how to create a subinterface number that is different from the VLAN ID:
878 : * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100}
879 : *
880 : *
881 : * Examples of how to create q-in-q and q-in-any subinterfaces:
882 : * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100 inner-dot1q 200}
883 : * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q any}
884 : *
885 : * Examples of how to create dot1ad interfaces:
886 : * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1ad 11}
887 : * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 12 dot1ad 100 inner-dot1q 200}
888 : *
889 : *
890 : * Examples of '<em>exact-match</em>' versus non-exact match. A packet with
891 : * outer VLAN 100 and inner VLAN 200 would match this interface, because the default
892 : * is non-exact match:
893 : * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100}
894 : *

2353 : * This command is used to start or stop a packet capture, or show
2354 : * the status of packet capture.
2355 : *
2356 : * This command has the following optional parameters:
2357 : *
2358 : *
2359 : * - <b>rx</b> - Capture received packets
2360 : *
2361 : * - <b>tx</b> - Capture transmitted packets
2362 : *
2363 : * - <b>drop</b> - Capture dropped packets
2364 : *
2365 : * - <b>off</b> - Stop capturing packets, write results to the specified file
2366 : *
2367 : * - <b>max <nn></b> - Depth of local buffer. Once '<em>nn</em>' number
2368 : * of packets have been received, buffer is flushed to file. Once another
2369 : * '<em>nn</em>' number of packets have been received, buffer is flushed
2370 : * to file, overwriting previous write. If not entered, value defaults
2371 : * to 100. Can only be updated if packet capture is off.
2372 : *
2373 : * - <b>max-bytes-per-pkt <nnnn></b> - Maximum number of bytes to capture
2374 : * for each packet. Must be >= 32, <= 9000.
2375 : *
2376 : * - <b>preallocate-data</b> - Preallocate the data buffer, to avoid
2377 : * vector expansion delays during pcap capture
2378 : *
2379 : * - <b>free-data</b> - Free the data buffer. Ordinarily it's a feature
2380 : * to retain the data buffer so this option is seldom used.
2381 : *
2382 : * - <b>intfc <interface-name>|any</b> - Used to specify a given interface,
2383 : * or use '<em>any</em>' to run packet capture on all interfaces.
2384 : * '<em>any</em>' is the default if not provided. Settings from a previous
2385 : * packet capture are preserved, so '<em>any</em>' can be used to reset
2386 : * the interface setting.
2387 : *
2388 : * - <b>filter</b> - Use the pcap trace rx / tx / drop filter, which
2389 : * must be configured. Use <b>classify filter pcap...</b> to configure the
2390 : * filter. The filter will only be executed if the per-interface or
2391 : * any-interface tests fail.
2392 : *
2393 : * - <b>error <node>.<error></b> - filter packets based on a specific error.
2394 : * For example: error {ip4-udp-lookup}.{no_listener}
2395 : *
2396 : * - <b>file <name></b> - Used to specify the output filename. The file will
2397 : * be placed in the '<em>/tmp</em>' directory, so only the filename is
2398 : * supported. Directory should not be entered. If file already exists, file
2399 : * will be overwritten. If no filename is provided, the file will be
2400 : * named "/tmp/rx.pcap", "/tmp/tx.pcap", "/tmp/rxandtx.pcap", etc.
2401 : * Can only be updated if packet capture is off.
2402 : *
2403 : * - <b>status</b> - Displays the current status and configured attributes
2404 : * associated with a packet capture. If packet capture is in progress,
2405 : * '<em>status</em>' also will return the number of packets currently in
2406 : * the local buffer. All additional attributes entered on command line
2407 : * with '<em>status</em>' will be ignored and not applied.
2408 : *
2409 : * @cliexpar
2410 : * Example of how to display the status of a tx packet capture when off:
2411 : * @cliexstart{pcap trace status}
2412 : * max is 100, for any interface to file /tmp/vpe.pcap
2413 : * pcap tx capture is off...
2414 : * @cliexend
2415 : * Example of how to start a tx packet capture:
2416 : * @cliexstart{pcap trace tx max 35 intfc GigabitEthernet0/8/0 file
2417 : * vppTest.pcap}
2418 : * @cliexend
2419 : * Example of how to display the status of a tx packet capture in progress:
2420 : * @cliexstart{pcap trace status}
2421 : * max is 35, for interface GigabitEthernet0/8/0 to file /tmp/vppTest.pcap
2422 : * pcap tx capture is on: 20 of 35 pkts...
2423 : * @cliexend
2424 : * Example of how to stop a tx packet capture:
2425 : * @cliexstart{pcap trace off}
2426 : * captured 21 pkts...
