A row in this table represents a Virtual Private Lan Service(VPLS) in a packet network. It is indexed by fsMplsVplsInstanceIndex, which uniquely identifies a single VPLS. A row is created by the operator or by the agent if a VPLS service is created by non-SNMP application or due to autodiscovery process. None of the read-create objects values can be changed when fsMplsVplsRowStatus is in the active(1) state. Changes are allowed when the fsMplsVplsRowStatus is in notInService(2) or notReady(3) states only. If the operator need to change one of the values for an active row the fsMplsVplsRowStatus should be first changed to notInService(2), the objects may be changed now, and later to active(1) in order to re-initiate the signaling process with the new values in effect.
