Section 5.9
Managing Port Security
Port security, or port access control, provides the ability to filter or accept traffic from specific MAC addresses.
Port security works by inspecting the source MAC addresses of received frames and validating them against the list
of MAC addresses authorized by the port. Unauthorized frames are filtered and, optionally, the part that received
the frame can be shut down permanently or for a specified period of time. An alarm will be raised indicating the
detected unauthorized MAC address.
Frames to unknown destination addresses are flooded through secure ports.
