What is eriRouterBridgePortPreviousState?
This accessible-for-notify INTEGER records a bridge port's prior spanning-tree state before a topology change, with values disabled, blocking, listening, learning, forwarding, or broken. It appears in eriRouterBridgeTopologyChangeEvent notifications alongside the new state (dot1dStpPortState) so an admin can see exactly what transition occurred. For example, a trap showing eriRouterBridgePortPreviousState of blocking(2) transitioning to forwarding tells the admin the port just came out of blocking into active forwarding.
