What is agentPortSecurityLastDiscardedMAC?
This read-only string reports the VLAN ID and source MAC address of the most recent packet discarded on a locked port due to a security violation. Admins check it after a violation trap fires to immediately see which device attempted unauthorized access without needing to dig through logs. A value showing an unfamiliar MAC address tells the admin exactly which device to investigate as the source of the most recent violation on that port.
