3. Select the desired security level:
❑ To disable port security on the switch, type 1 to select Automatic
mode. A switch operating in Automatic mode does not restrict the
number of MAC addresses learned by the ports. The switch
continues to learn addresses so long as there is available space in
the MAC address table. This is the default setting.
❑ To specify a maximum number of MAC addresses each port can
learn, type 2 to select Limited mode. To specify the limits, perform
the procedure in Configuring the Limited Security Mode on
page 69.
❑ To forward frames based solely on static MAC addresses, type 3 to
select the Secured mode. After activating this security mode, you
must enter the static MAC addresses of the nodes with frames the
switch is to forward. For instructions on how to add static MAC
addresses, refer to Adding Static MAC Addresses on page 137.
