What is filterLastSrc?
This read-only OCTET STRING holds the source MAC address of the most recent packet discarded by this filter. An admin uses this to quickly identify which specific device is currently triggering a given filter without needing a packet capture. Checking filterLastSrc after filterPktCnts starts climbing quickly reveals which host on the network is generating the traffic being blocked.
