Configuring Port Security on Access Ports
This example shows how to set the aging time to 2 minutes:
Switch(config-if)# switchport port-security aging time 2
You can verify the previous commands with the show port-security interface command.
Example 4: Setting the Aging Timer Type
This example shows how to set the aging timer type to Inactivity for the secure addresses on the Fast
Ethernet interface 3/5:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface fastethernet 3/5

Switch(config-if)# switchport mode access
Switch(config-if)# switchport port-security
Switch(config-if)# switchport port-security maximum 10
Switch(config-if)# switchport port-security mac-address 0000.0000.0003 (Static secure MAC)
Switch(config-if)# end
Switch#show port address
