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