The subinterface + * is a double dot1q vlan with any outer vlan id and any inner vlan id. + * + * For each of the above CLI, there is a duplicate that uses the keyword + * "dot1ad" in place of the first "dot1q". These interfaces use ethertype + * 0x88ad in place of 0x8100 for the outer ethertype. Note that for double- + * tagged packets the inner ethertype is always 0x8100. Also note that + * the dot1q and dot1ad naming spaces are independent, so it is legal to + * have both "Gig3/0/0.1 dot1q 100" and "Gig3/0/0.2 dot1ad 100". For example: + * + * <intf-name> <id> dot1ad <outer_id> inner-dot1q <inner_id> [exact-match] + * - a subinterface with the name <intf-name>.<id>. The subinterface + * is a double dot1ad vlan with outer vlan id <outer_id> and inner vlan + * id <inner_id>. + * + * <intf-name> <id> untagged + * - a subinterface with the name <intf-name>.<id>. The subinterface + * has no vlan tags. Only one can be specified per interface. + * + * <intf-name> <id> default + * - a subinterface with the name <intf-name>.<id>. This is associated + * with a packet that did not match any other configured subinterface + * on this interface.
