Each row entry represents a backplane ethernet DSL port on an IOM card in a chassis in the system. Entries cannot be created and deleted via SNMP SET operations. Entries in this table will be created automatically when the tmnxMDAAssignedType object is set to a p8-xdsl or p6-dsl MDA type. The aluDslPortEntry contains attributes that are unique to the 'XDSL' or 'SHDSL' tmnxPortType. The tmnxPortPortID contains the slot, mda and port numbers encoded into it. For each aluDslPortEntry, there will be a corresponding entry in the tmnxPortTable and the ifTable.
