Disabling And Enabling Cdp On An Interface - Cisco ME 3400 Software Configuration Manual

Configuring CDP

Disabling and Enabling CDP on an Interface

CDP is enabled by default on NNIs to send and to receive CDP information. You can enable CDP on
ENIs, but it is not supported on UNIs. Beginning in privileged EXEC mode, follow these steps to disable
CDP on a port:
Command
Step 1 configure terminal
Step 2 interface interface-id
Step 3 no cdp enable
Step 4 end
Step 5 copy running-config startup-config
Beginning in privileged EXEC mode, follow these steps to enable CDP on a port when it has been
disabled:
Command
Step 1 configure terminal
Step 2 interface interface-id
Step 3
cdp enable
Step 4 end
Step 5 copy running-config startup-config
This example shows how to enable CDP on a port when it has been disabled.
Switch# configure terminal
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# cdp enable
Switch(config-if)# end
This example shows how to change a UNI to an ENI and enable CDP on the port.
Switch# configure terminal
Switch(config)# interface fastethernet0/1
Switch(config-if)# port-type eni
Switch(config-if)# cdp enable
Switch(config-if)# end
