What is accBrPortInDupPkts?
This counter records duplicate packets detected on incoming traffic to the port, which indicates the spanning tree loop prevention isn't working or that a hardware issue is creating unwanted copies of frames. A rising duplicate packet counter is a red flag signaling active loops in the network topology that must be resolved immediately. If this counter jumps from 0 to 500 duplicates over 5 minutes, a spanning tree loop is actively forwarding the same frame multiple times.
