Each row entry represents a configured sonet path in a packet over Sonet port on a IOM card in a chassis in the system. The tmnxSonetPathEntry contains attributes that are unique to a sonet path of a 'sonet' TmnxPortType. The tmnxPortPortID for a sonet port includes a sonet path number in the lower bits. If the sonet path number is zero, '0', it represents a single (clear) sonet path on the port that uses the full bandwidth of the sonet port. Entries in this table that have the sonet path number part of their tmnxPortPortID index value set to zero cannot be created and deleted via SNMP SET operations. They are created by the SNMP agent when the corresponding entry in the tmnxSonetTable is created.

Entries with non-zero sonet path numbers can be created and deleted via SNMP SET operations using tmnxSonetPathRowStatus. When a row is created in the tmnxSonetPathTable, the agent also creates a row with the same index values in the tmnxPortTable. In order to delete an entry, tmnxPortAdminStatus must first be set to 'outOfService'. When the tmnxSonetPathEntry is deleted, the agent also deletes the corresponding row in the tmnxPortTable.
