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

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