Section II: Local and Telnet Mangement

6. Select the desired security level by typing the corresponding letter:

❑ To disable port security on the switch, type A 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 L to select Limited mode. To specify the limits, perform

the procedure in Configuring the Limited Security Mode on

page 71.

❑ To forward frames based solely on static MAC addresses, type S 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 Deleting All Dynamic MAC Addresses on

page 159.

❑ To stop the switch from learning new dynamic MAC addresses

and have it forward frames based only on static MAC addresses

and on those dynamic addresses that it has already learned, type

K to select Lock all the ports now.

Note

Only one security level can be active on a switch at a time.

A change to the security level is immediately activated on the

switch.
