Module: NORTEL-NETWORKS-RAPID-SPANNING-TREE-MIB
OID (symbolic): NORTEL-NETWORKS-RAPID-SPANNING-TREE-MIB::nnRstDot1wPortTopoChSmState
OID (numeric): 1.3.6.1.4.1.45.5.4.1.2.2.1.8
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This indicates the current state of the Topology Change state machine.
This object will hold the value 'init' when the Topology Change state machine is in the INIT state, the value 'inactive' when the state machine is in the INACTIVE state, the value 'active' when the state machine is in the ACTIVE state, the value 'detected' when the state machine is in the DETECTED state, the value 'notifiedtcn' when the state machine is in the NOTIFIED_TCN state, the value 'notifiedtc' when the state machine is in the NOTIFIED_TC state, the value 'propagating' state when the state machine is in the PROPAGATING state and the value 'acknowledged' when the state machine is in the ACKNOWLEDGED state.
What is nnRstDot1wPortTopoChSmState?
Reports the current state of this port's Topology Change state machine (e.g. detected, notifiedtc, propagating, acknowledged), used to trace how a detected topology change is being propagated through the spanning-tree domain from this port.
