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

OID (symbolic): NORTEL-NETWORKS-RAPID-SPANNING-TREE-MIB::nnRstDot1wPortRoleSelSmState

OID (numeric): 1.3.6.1.4.1.45.5.4.1.2.1.4

What is nnRstDot1wPortRoleSelSmState?

Reports whether the bridge-wide Port Role Selection state machine is still initializing (initbridge) or actively assigning port roles (roleselection); mostly useful when debugging why RSTP role assignment appears stuck.
