What is agentPortSecurityLastDiscardedMAC?
This read-only string reports the VLAN ID and source MAC address of the most recent packet discarded due to a port security violation on this port. Admins check it to quickly identify the offending device behind the latest violation without needing to have caught the corresponding trap in real time. An agentPortSecurityLastDiscardedMAC reading 5 a0:b1:c2:99:88:77 tells the admin that MAC address on VLAN 5 was the most recent unauthorized device blocked from this port.
