Each conceptual row represents the set of Distributed subscriber management configuration data for a range of VLAN Q-tags on a particular interface, or for the interface itself. Users whose traffic comes in on this interface tagged with a matching VLAN Q-tag are to be processed according to the configuration specified in this conceptual row; otherwise, the default configuration specified in the default range [4096-4096] must be used. Rows in this table are created and destroyed automatically by the system. A single row in this table is always created by the system and cannot be destroyed: the default range [4096-4096].
