switchport port-security aging
To allow unlimited access to a secure address, configure it as a secure address, and disable aging for the
statically configured secure address by using the no switchport port-security aging static interface
configuration command.
Examples This example sets the aging time as 2 hours for absolute aging for all the secure addresses on a port:
Switch(config)# interface fastethernet0/1
Switch(config-if)# switchport port-security aging time 120
This example sets the aging time as 2 minutes for inactivity aging type for configured secure addresses
on a port:
Switch(config)# interface fastethernet0/2
Switch(config-if)# switchport port-security aging time 2
Switch(config-if)# switchport port-security aging type inactivity
Switch(config-if)# switchport port-security aging static
This example shows how to disable aging for configured secure addresses:
Switch(config-if)# no switchport port-security aging static
