Configuring Destination Port Permit Lists (Optional)

To prevent accidental configuration of ports as destinations, you can create a permit list of the ports that
are valid for use as destinations. With a destination port permit list configured, you can only configure
the ports in the permit list as destinations.
To configure a destination port permit list, perform this task:
Command
Step 1
Router# configure terminal
Step 2
Router(config)# monitor permit-list
Step 3
Router(config)# no monitor permit-list
Step 4
Router(config)# monitor permit-list destination
1
interface type
slot/port - port]
Step 5
Router(config)# no monitor permit-list destination
1
interface type
slot/port - port]
Step 6
Router(config)# do show monitor permit-list
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
This example shows how to configure a destination port permit list that includes Gigabit Ethernet ports
5/1 through 5/4 and 6/1:
Router# configure terminal
Router(config)# monitor permit-list
Router(config)# monitor permit-list destination interface gigabitethernet 5/1-4,
gigabitethernet 6/1
This example shows how to verify the configuration:
Router(config)# do show monitor permit-list
