556  * Parse subinterface names.
557  *
558  * The following subinterface syntax is supported. The first two are for
559  * backwards compatability:
560  *
561  * <intf-name> <id>
562  * - a subinterface with the name <intf-name>.<id>. The subinterface
563  * is a single dot1q vlan with vlan id <id> and exact-match semantics.
564  *
565  * <intf-name> <min_id>-<max_id>
566  * - a set of the above subinterfaces, repeating for each id
567  * in the range <min_id> to <max_id>
568  *
569  * In the following, exact-match semantics (i.e. the number of vlan tags on the
570  * packet must match the number of tags in the configuration) are used only if
571  * the keyword exact-match is present. Non-exact match is the default.
572  *
573  * <intf-name> <id> dot1q <outer_id> [exact-match]
574  * - a subinterface with the name <intf-name>.<id>. The subinterface
575  * is a single dot1q vlan with vlan id <outer_id>.
576  *
577  * <intf-name> <id> dot1q any [exact-match]
578  * - a subinterface with the name <intf-name>.<id>. The subinterface
579  * is a single dot1q vlan with any vlan id.
580  *
581  * <intf-name> <id> dot1q <outer_id> inner-dot1q <inner_id> [exact-match]
582  * - a subinterface with the name <intf-name>.<id>. The subinterface
583  * is a double dot1q vlan with outer vlan id <outer_id> and inner vlan id
584  * <inner_id>.
585  *
586  * <intf-name> <id> dot1q <outer_id> inner-dot1q any [exact-match]
587  * - a subinterface with the name <intf-name>.<id>. The subinterface
588  * is a double dot1q vlan with outer vlan id <id> and any inner vlan id.
589  *
590  * <intf-name> <id> dot1q any inner-dot1q any [exact-match]
591  *
592  * - a subinterface with the name <intf-name>.<id>. The subinterface
593  * is a double dot1q vlan with any outer vlan id and any inner vlan id.
594  *
595  * For each of the above CLI, there is a duplicate that uses the keyword
596  * "dot1ad" in place of the first "dot1q". These interfaces use ethertype
597  * 0x88ad in place of 0x8100 for the outer ethertype. Note that for double-
598  * tagged packets the inner ethertype is always 0x8100. Also note that
599  * the dot1q and dot1ad naming spaces are independent, so it is legal to
600  * have both "Gig3/0/0.1 dot1q 100" and "Gig3/0/0.2 dot1ad 100". For example:
601  *
602  * <intf-name> <id> dot1ad <outer_id> inner-dot1q <inner_id> [exact-match]
603  * - a subinterface with the name <intf-name>.<id>. The subinterface
604  * is a double dot1ad vlan with outer vlan id <outer_id> and inner vlan
605  * id <inner_id>.
606  *
607  * <intf-name> <id> untagged
608  * - a subinterface with the name <intf-name>.<id>. The subinterface
609  * has no vlan tags. Only one can be specified per interface.
610  *
611  * <intf-name> <id> default
612  * - a subinterface with the name <intf-name>.<id>. This is associated
613  * with a packet that did not match any other configured subinterface
614  * on this interface. Only one can be specified per interface.

795  * This command is used to add VLAN IDs to interfaces, also known as subinterfaces.
796  * The primary input to this command is the '<em>interface</em>' and '<em>subId</em>'
797  * (subinterface Id) parameters. If no additional VLAN ID is provide, the VLAN ID is
798  * assumed to be the '<em>subId</em>'. The VLAN ID and '<em>subId</em>' can be different,
799  * but this is not recommended.
800  *
801  * This command has several variations:
802  * - <b>create sub-interfaces <interface> <subId></b> - Create a subinterface to
803  * process packets with a given 802.1q VLAN ID (same value as the '<em>subId</em>').
804  *
805  * - <b>create sub-interfaces <interface> <subId> default</b> - Adding the
806  * '<em>default</em>' parameter indicates that packets with VLAN IDs that do not
807  * match any other subinterfaces should be sent to this subinterface.
808  *
809  * - <b>create sub-interfaces <interface> <subId> untagged</b> - Adding the
810  * '<em>untagged</em>' parameter indicates that packets no VLAN IDs should be sent
811  * to this subinterface.
812  *
813  * - <b>create sub-interfaces <interface> <subId>-<subId></b> - Create a range of
814  * subinterfaces to handle a range of VLAN IDs.
815  *
816  * - <b>create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any [exact-match]</b> -
817  * Use this command to specify the outer VLAN ID, to either be explicited or to make the
818  * VLAN ID different from the '<em>subId</em>'.
819  *
820  * - <b>create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any inner-dot1q
821  * <vlanId>|any [exact-match]</b> - Use this command to specify the outer VLAN ID and
822  * the innner VLAN ID.
823  *
824  * When '<em>dot1q</em>' or '<em>dot1ad</em>' is explictly entered, subinterfaces
825  * can be configured as either exact-match or non-exact match. Non-exact match is the CLI
826  * default. If '<em>exact-match</em>' is specified, packets must have the same number of
827  * VLAN tags as the configuration. For non-exact-match, packets must at least that number
828  * of tags. L3 (routed) interfaces must be configured as exact-match. L2 interfaces are
829  * typically configured as non-exact-match. If '<em>dot1q</em>' or '<em>dot1ad</em>' is NOT
830  * entered, then the default behavior is exact-match.
831  *
832  * Use the '<em>show interface</em>' command to display all subinterfaces.

836  * Example of how to create a VLAN subinterface 11 to process packets on 802.1q VLAN ID 11:
837  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11}
838  *
839  * The previous example is shorthand and is equivalent to:
840  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 11 exact-match}
841  *
842  *
843  * Example of how to create a subinterface number that is different from the VLAN ID:
844  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100}
845  *
846  *
847  * Examples of how to create q-in-q and q-in-any subinterfaces:
848  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100 inner-dot1q 200}
849  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q any}
850  *
851  * Examples of how to create dot1ad interfaces:
852  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1ad 11}
853  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 12 dot1ad 100 inner-dot1q 200}
854  *
855  *
856  * Examples of '<em>exact-match</em>' versus non-exact match. A packet with
857  * outer VLAN 100 and inner VLAN 200 would match this interface, because the default
858  * is non-exact match:
859  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100}
860  *
861  * However, the same packet would NOT match this interface because '<em>exact-match</em>'
862  * is specified and only one VLAN is configured, but packet contains two VLANs:
863  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100 exact-match}
864  *
865  *
866  * Example of how to created a subinterface to process untagged packets:
867  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 untagged}
868  *
869  * Example of how to created a subinterface to process any packet with a VLAN ID that
870  * does not match any other subinterface:
871  * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 7 default}
872  *
873  * When subinterfaces are created, they are in the down state. Example of how to
874  * enable a newly created subinterface:
