Activating a Port Security Level
The following procedure explains how to activate a port security level on
a stack.
Note
Before activating the Limited security level, configure the maximum
number of MAC addresses each port group can learn. For
instructions, refer to Configuring Limited Security Level on page
72.
Note
This procedure can only be performed from a local management
session. You cannot perform it from a Telnet management session.
You can perform this procedure on any switch in a stack. All switches in
the stack are automatically changed to the same security level. Only one
security level can be active in a stack at a time.
To activate port security on a stack, perform the following procedure:
1. From the Main Menu, type 1 to select Ports Menu.
2. From the Ports Menu, type 5 to select Port Security.
