The tmnxNatLsnSubscIdStrTable associates subscriber strings with Large Scale NAT subscribers. The strings are taken from RADIUS messages according to the configuration in the tmnxNatSubIdTable. A subscriber string can be associated with more than one Large Scale NAT subscriber. Given a known subscriber string, this table provides the index values to retrieve the inside information of (one or more) associated Large Scale NAT subscribers, for example in the tmnxNatLsnHostTable. Rows in this table are created and destroyed automatically by the system.
