Port Security Table

This table displays the security status of each port. A port can have a number of authorized MAC addresses, which are displayed in the Port Address Table.

Double-click any entry to edit information for that row.

Slot

Port

Displays the number of the port in question.

Mode

Displays the learning and security modes of the port. Possible values are No Restrictions, Continuous Learning, Auto Learn, and Secure. No Restrictions disables all learning and security. Continuous Learning means that addresses are learned continually. If more addresses are learned than are permitted on the port, the older entries will be aged out. Auto Learn deletes all addresses for this port, learns addresses up to the number permitted, then sets Port Mode to secure. Secure disables learning.

When in a learning mode, Num Addr displays the maximum number of addresses that can be learned on the port. This can be set by the user.

A trap is sent whenever a station has been learned, and a different trap is sent whenever a packet is received from an unauthorized station.
