nnRstDot1wPortEffectivePortState

Module: NORTEL-NETWORKS-RAPID-SPANNING-TREE-MIB

OID (symbolic): NORTEL-NETWORKS-RAPID-SPANNING-TREE-MIB::nnRstDot1wPortEffectivePortState

OID (numeric): 1.3.6.1.4.1.45.5.4.1.2.2.1.20

Node type: OBJECT-TYPE

Description: The effective Operational state of the port. This object will be set to TRUE only when the port is operationally up in the interface manager and the force Port State for this port and specified port state is enabled. Otherwise this object is set to FALSE.

What is nnRstDot1wPortEffectivePortState?

Reports TRUE only when the port is both operationally up in the interface manager and its forced port state matches the specified state, giving an admin a single combined signal for whether the port's forced spanning-tree state is actually taking effect.

Examples
