565  * Parse subinterface names.
566  *
567  * The following subinterface syntax is supported. The first two are for
568  * backwards compatability:
569  *
570  * <intf-name> <id>
571  * - a subinterface with the name <intf-name>.<id>. The subinterface
572  * is a single dot1q vlan with vlan id <id> and exact-match semantics.
573  *
574  * <intf-name> <min_id>-<max_id>
575  * - a set of the above subinterfaces, repeating for each id
576  * in the range <min_id> to <max_id>
577  *
578  * In the following, exact-match semantics (i.e. the number of vlan tags on the
579  * packet must match the number of tags in the configuration) are used only if
580  * the keyword exact-match is present. Non-exact match is the default.
581  *
582  * <intf-name> <id> dot1q <outer_id> [exact-match]
583  * - a subinterface with the name <intf-name>.<id>. The subinterface
584  * is a single dot1q vlan with vlan id <outer_id>.
585  *
586  * <intf-name> <id> dot1q any [exact-match]
587  * - a subinterface with the name <intf-name>.<id>. The subinterface
588  * is a single dot1q vlan with any vlan id.
589  *
590  * <intf-name> <id> dot1q <outer_id> inner-dot1q <inner_id> [exact-match]
591  * - a subinterface with the name <intf-name>.<id>. The subinterface
592  * is a double dot1q vlan with outer vlan id <outer_id> and inner vlan id
593  * <inner_id>.
594  *
595  * <intf-name> <id> dot1q <outer_id> inner-dot1q any [exact-match]
596  * - a subinterface with the name <intf-name>.<id>. The subinterface
597  * is a double dot1q vlan with outer vlan id <id> and any inner vlan id.
598  *
599  * <intf-name> <id> dot1q any inner-dot1q any [exact-match]
600  *
601  * - a subinterface with the name <intf-name>.<id>. The subinterface
602  * is a double dot1q vlan with any outer vlan id and any inner vlan id.
603  *
604  * For each of the above CLI, there is a duplicate that uses the keyword
605  * "dot1ad" in place of the first "dot1q". These interfaces use ethertype
606  * 0x88ad in place of 0x8100 for the outer ethertype. Note that for double-
607  * tagged packets the inner ethertype is always 0x8100. Also note that
608  * the dot1q and dot1ad naming spaces are independent, so it is legal to
609  * have both "Gig3/0/0.1 dot1q 100" and "Gig3/0/0.2 dot1ad 100". For example:
610  *
611  * <intf-name> <id> dot1ad <outer_id> inner-dot1q <inner_id> [exact-match]
612  * - a subinterface with the name <intf-name>.<id>. The subinterface
613  * is a double dot1ad vlan with outer vlan id <outer_id> and inner vlan
614  * id <inner_id>.
615  *
616  * <intf-name> <id> untagged
617  * - a subinterface with the name <intf-name>.<id>. The subinterface
618  * has no vlan tags. Only one can be specified per interface.
619  *
620  * <intf-name> <id> default
621  * - a subinterface with the name <intf-name>.<id>. This is associated
622  * with a packet that did not match any other configured subinterface
623  * on this interface. Only one can be specified per interface.

804  * This command is used to add VLAN IDs to interfaces, also known as subinterfaces.
805  * The primary input to this command is the '<em>interface</em>' and '<em>subId</em>'
806  * (subinterface Id) parameters. If no additional VLAN ID is provide, the VLAN ID is
807  * assumed to be the '<em>subId</em>'. The VLAN ID and '<em>subId</em>' can be different,
808  * but this is not recommended.
809  *
810  * This command has several variations:
811  * - <b>create sub-interfaces <interface> <subId></b> - Create a subinterface to
812  * process packets with a given 802.1q VLAN ID (same value as the '<em>subId</em>').
813  *
814  * - <b>create sub-interfaces <interface> <subId> default</b> - Adding the
815  * '<em>default</em>' parameter indicates that packets with VLAN IDs that do not
816  * match any other subinterfaces should be sent to this subinterface.
817  *
818  * - <b>create sub-interfaces <interface> <subId> untagged</b> - Adding the
819  * '<em>untagged</em>' parameter indicates that packets no VLAN IDs should be sent
820  * to this subinterface.
821  *
822  * - <b>create sub-interfaces <interface> <subId>-<subId></b> - Create a range of
823  * subinterfaces to handle a range of VLAN IDs.
824  *
825  * - <b>create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any [exact-match]</b> -
826  * Use this command to specify the outer VLAN ID, to either be explicited or to make the
827  * VLAN ID different from the '<em>subId</em>'.
828  *
829  * - <b>create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any inner-dot1q
830  * <vlanId>|any [exact-match]</b> - Use this command to specify the outer VLAN ID and
831  * the innner VLAN ID.
832  *
833  * When '<em>dot1q</em>' or '<em>dot1ad</em>' is explictly entered, subinterfaces
834  * can be configured as either exact-match or non-exact match. Non-exact match is the CLI
835  * default. If '<em>exact-match</em>' is specified, packets must have the same number of
836  * VLAN tags as the configuration. For non-exact-match, packets must at least that number
837  * of tags. L3 (routed) interfaces must be configured as exact-match. L2 interfaces are
838  * typically configured as non-exact-match. If '<em>dot1q</em>' or '<em>dot1ad</em>' is NOT
839  * entered, then the default behavior is exact-match.
840  *
841  * Use the '<em>show interface</em>' command to display all subinterfaces.

845  * Example of how to create a VLAN subinterface 11 to process packets on 802.1q VLAN ID 11:
846  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11}
847  *
848  * The previous example is shorthand and is equivalent to:
849  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 11 exact-match}
850  *
851  *
852  * Example of how to create a subinterface number that is different from the VLAN ID:
853  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100}
854  *
855  *
856  * Examples of how to create q-in-q and q-in-any subinterfaces:
857  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100 inner-dot1q 200}
858  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q any}
859  *
860  * Examples of how to create dot1ad interfaces:
861  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1ad 11}
862  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 12 dot1ad 100 inner-dot1q 200}
863  *
864  *
865  * Examples of '<em>exact-match</em>' versus non-exact match. A packet with
866  * outer VLAN 100 and inner VLAN 200 would match this interface, because the default
867  * is non-exact match:
868  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100}
869  *
870  * However, the same packet would NOT match this interface because '<em>exact-match</em>'
871  * is specified and only one VLAN is configured, but packet contains two VLANs:
872  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100 exact-match}
873  *
874  *
875  * Example of how to created a subinterface to process untagged packets:
876  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 untagged}
877  *
878  * Example of how to created a subinterface to process any packet with a VLAN ID that
879  * does not match any other subinterface:
880  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 7 default}
881  *
882  * When subinterfaces are created, they are in the down state. Example of how to
883  * enable a newly created subinterface:
