MAC Port Security Overview

The MAC Port Security function is intended to filter incoming frames
with an unauthorized source MAC address (SA) on a secured port.
When a frame is received on a secured port, its SA is checked against the
MAC Address Table. If the SA is not found in the MAC Address T able or it
is found but has a different port location than the incoming frame, the
frame is rejected without being learned. A message is then sent to the
Agent.
The Agent reports the attempted intrusion with an SNMP security
violation trap containing the intruder's MAC address. To prevent the
flooding of the Console's trap log or network, the Agent sends an intruder
alert every 5 seconds for the first 3 times a specific intruder is detected on
a port, and then every 15 minutes if the intrusion continues.

Configuring MAC Port Security

To apply MAC Port Security to a selected port:
1. Select Configure > MAC Port Security. The MAC Port Security dialog
box opens.
