❑ To specify a maximum number of dynamic MAC addresses each
port can learn, type L to select Limited mode. To specify the limits,
refer to the next procedure.

have it forward frames based only on static MAC addresses and on
those dynamic addresses that it has already learned, type S to
select Secure mode.
Note
Only one security level can be active on a port at a time.
A change to the security level is immediately activated on the port
and the new setting is displayed in the Port Security Configuration
Menu.
