a3ComSysBridgePortReceiveBlockedDiscards
Module: A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB
OID (symbolic): A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB::a3ComSysBridgePortReceiveBlockedDiscards
OID (numeric): 1.3.6.1.4.1.43.29.4.10.3.1.7
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The number of frames discarded by the bridge port identified by this entry because the receiving bridge port was not in the 'forwarding' state.
What is a3ComSysBridgePortReceiveBlockedDiscards?
This counter tracks frames dropped because the port was not in forwarding state (blocked by STP). Engineers use it to confirm STP is working and detect unexpected port blocks that impede traffic flow. A large value spike indicates recent topology changes or STP recalculation.
