Chapter 26 Configuring Port Security
Displaying Port Security Settings
To configure port security aging, perform this task:
When configuring port security aging, note the following:
• With all releases, you can enter the no keyword to disable aging.
• For Release 12.1(19)E and later releases, the valid aging-time range is from 1 to 1440 minutes.
• For releases earlier than Release 12.1(19)E, the valid aging-time range is from 0 to 1440 minutes. You
can enter zero to disable aging.
This example shows how to set the aging time as 2 hours for the secure addresses on the Fast Ethernet
interface 5/1:
Router(config)# interface fastethernet 5/1
Router(config-if)# switchport port-security aging time 120
This example shows how to set the aging time as 2 minutes:
Router(config-if)# switchport port-security aging time 2
You can verify the previous commands by entering the show port-security interface interface_id
privileged EXEC command.
Displaying Port Security Settings
The show interfaces interface_id switchport privileged EXEC command displays the interface traffic
suppression and control configuration. The show interfaces counters privileged EXEC commands
display the count of discarded packets. The show storm control and show port-security privileged
EXEC commands display those features.
