Configuring Port Security
The Fast Ethernet switch has a port security feature that can be used to
enhance network security. This feature allows you to control network
access by limiting the number of MAC addresses that are learned on the
ports on a switch in a stack.
Note
The port security feature does not apply to ports on any expansion
modules installed in the switch.
To set the port security level for the ports on a switch, perform the
following procedure:
1. From the Main Menu, select the switch where you want to configure
port security.
2. From the Omega Main Menu, select System Configuration.
The System Configuration menu in Figure 7 on page 39 is
displayed.
3. Select Security/Source Address Table.
The following window is displayed:

Automatic
This selection disables port security. With this option activated,
the switch will not restrict the number of MAC addresses that are
learned on the switch ports. This is the default setting.
