564 * - a subinterface with the name <intf-name>.<id>. The subinterface
565 * is a single dot1q vlan with vlan id <id> and exact-match semantics.
567 * <intf-name> <min_id>-<max_id>
568 * - a set of the above subinterfaces, repeating for each id
569 * in the range <min_id> to <max_id>
571 * In the following, exact-match semantics (i.e. the number of vlan tags on the
572 * packet must match the number of tags in the configuration) are used only if
573 * the keyword exact-match is present. Non-exact match is the default.
575 * <intf-name> <id> dot1q <outer_id> [exact-match]
576 * - a subinterface with the name <intf-name>.<id>. The subinterface
577 * is a single dot1q vlan with vlan id <outer_id>.
579 * <intf-name> <id> dot1q any [exact-match]
580 * - a subinterface with the name <intf-name>.<id>. The subinterface
581 * is a single dot1q vlan with any vlan id.
583 * <intf-name> <id> dot1q <outer_id> inner-dot1q <inner_id> [exact-match]
584 * - a subinterface with the name <intf-name>.<id>. The subinterface
585 * is a double dot1q vlan with outer vlan id <outer_id> and inner vlan id
588 * <intf-name> <id> dot1q <outer_id> inner-dot1q any [exact-match]
589 * - a subinterface with the name <intf-name>.<id>. The subinterface
590 * is a double dot1q vlan with outer vlan id <id> and any inner vlan id.
592 * <intf-name> <id> dot1q any inner-dot1q any [exact-match]
594 * - a subinterface with the name <intf-name>.<id>. The subinterface
595 * is a double dot1q vlan with any outer vlan id and any inner vlan id.
597 * For each of the above CLI, there is a duplicate that uses the keyword
598 * "dot1ad" in place of the first "dot1q". These interfaces use ethertype
599 * 0x88ad in place of 0x8100 for the outer ethertype. Note that for double-
600 * tagged packets the inner ethertype is always 0x8100. Also note that
601 * the dot1q and dot1ad naming spaces are independent, so it is legal to
602 * have both "Gig3/0/0.1 dot1q 100" and "Gig3/0/0.2 dot1ad 100". For example:
604 * <intf-name> <id> dot1ad <outer_id> inner-dot1q <inner_id> [exact-match]
605 * - a subinterface with the name <intf-name>.<id>. The subinterface
606 * is a double dot1ad vlan with outer vlan id <outer_id> and inner vlan
609 * <intf-name> <id> untagged
610 * - a subinterface with the name <intf-name>.<id>. The subinterface
611 * has no vlan tags. Only one can be specified per interface.
613 * <intf-name> <id> default
614 * - a subinterface with the name <intf-name>.<id>. This is associated
615 * with a packet that did not match any other configured subinterface
616 * on this interface. Only one can be specified per interface.

797 * This command is used to add VLAN IDs to interfaces, also known as subinterfaces.
798 * The primary input to this command is the '<em>interface</em>' and '<em>subId</em>'
799 * (subinterface Id) parameters. If no additional VLAN ID is provide, the VLAN ID is
800 * assumed to be the '<em>subId</em>'. The VLAN ID and '<em>subId</em>' can be different,
801 * but this is not recommended.
803 * This command has several variations:
804 * - <b>create sub-interfaces <interface> <subId></b> - Create a subinterface to
805 * process packets with a given 802.1q VLAN ID (same value as the '<em>subId</em>').
807 * - <b>create sub-interfaces <interface> <subId> default</b> - Adding the
808 * '<em>default</em>' parameter indicates that packets with VLAN IDs that do not
809 * match any other subinterfaces should be sent to this subinterface.
811 * - <b>create sub-interfaces <interface> <subId> untagged</b> - Adding the
812 * '<em>untagged</em>' parameter indicates that packets no VLAN IDs should be sent
813 * to this subinterface.
815 * - <b>create sub-interfaces <interface> <subId>-<subId></b> - Create a range of
816 * subinterfaces to handle a range of VLAN IDs.
818 * - <b>create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any [exact-match]</b> -
819 * Use this command to specify the outer VLAN ID, to either be explicit or to make the
820 * VLAN ID different from the '<em>subId</em>'.
822 * - <b>create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any inner-dot1q
823 * <vlanId>|any [exact-match]</b> - Use this command to specify the outer VLAN ID and
826 * When '<em>dot1q</em>' or '<em>dot1ad</em>' is explicitly entered, subinterfaces
827 * can be configured as either exact-match or non-exact match. Non-exact match is the CLI
828 * default. If '<em>exact-match</em>' is specified, packets must have the same number of
829 * VLAN tags as the configuration. For non-exact-match, packets must at least that number
830 * of tags. L3 (routed) interfaces must be configured as exact-match. L2 interfaces are
831 * typically configured as non-exact-match. If '<em>dot1q</em>' or '<em>dot1ad</em>' is NOT
832 * entered, then the default behavior is exact-match.
834 * Use the '<em>show interface</em>' command to display all subinterfaces.
838 * Example of how to create a VLAN subinterface 11 to process packets on 802.1q VLAN ID 11:
839 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11}
841 * The previous example is shorthand and is equivalent to:
842 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 11 exact-match}
845 * Example of how to create a subinterface number that is different from the VLAN ID:
846 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100}
849 * Examples of how to create q-in-q and q-in-any subinterfaces:
850 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100 inner-dot1q 200}
851 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q any}
853 * Examples of how to create dot1ad interfaces:
854 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1ad 11}
855 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 12 dot1ad 100 inner-dot1q 200}
858 * Examples of '<em>exact-match</em>' versus non-exact match. A packet with
859 * outer VLAN 100 and inner VLAN 200 would match this interface, because the default
860 * is non-exact match:
861 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100}
863 * However, the same packet would NOT match this interface because '<em>exact-match</em>'
864 * is specified and only one VLAN is configured, but packet contains two VLANs:
865 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100 exact-match}
868 * Example of how to created a subinterface to process untagged packets:
869 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 untagged}
871 * Example of how to created a subinterface to process any packet with a VLAN ID that
872 * does not match any other subinterface:
873 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 7 default}
875 * When subinterfaces are created, they are in the down state. Example of how to
876 * enable a newly created subinterface:
877 * @cliexcmd{set interface GigabitEthernet2/0/0.7 up}

1935 * - <b>max <nn></b> - Depth of local buffer. Once '<em>nn</em>' number
1936 * of packets have been received, buffer is flushed to file. Once another
1937 * '<em>nn</em>' number of packets have been received, buffer is flushed
1938 * to file, overwriting previous write. If not entered, value defaults
1939 * to 100. Can only be updated if packet capture is off.
1941 * - <b>intfc <interface>|any</b> - Used to specify a given interface,
1942 * or use '<em>any</em>' to run packet capture on all interfaces.
1943 * '<em>any</em>' is the default if not provided. Settings from a previous
1944 * packet capture are preserved, so '<em>any</em>' can be used to reset
1945 * the interface setting.
1947 * - <b>file <name></b> - Used to specify the output filename. The file will
1948 * be placed in the '<em>/tmp</em>' directory, so only the filename is
1949 * supported. Directory should not be entered. If file already exists, file
1950 * will be overwritten. If no filename is provided, '<em>/tmp/vpe.pcap</em>'
1951 * will be used. Can only be updated if packet capture is off.
1953 * - <b>status</b> - Displays the current status and configured attributes
1954 * associated with a packet capture. If packet capture is in progress,
1955 * '<em>status</em>' also will return the number of packets currently in
1956 * the local buffer. All additional attributes entered on command line
1957 * with '<em>status</em>' will be ignored and not applied.
1960 * Example of how to display the status of a tx packet capture when off:
1961 * @cliexstart{pcap tx trace status}
1962 * max is 100, for any interface to file /tmp/vpe.pcap
