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

Command Purpose

Step 1 configure terminal Enter global configuration mode.

Step 2 interface interface-id Specify the interface on which you are disabling CDP, and enter

interface configuration mode.

Note If the interface is a UNI, you must enter the port-type nni or

port-type eni interface configuration command before

configuring CDP. By default, CDP is enabled on NNIs and

disabled on ENIs.

Step 3 no cdp enable Disable CDP on the interface.

Step 4 end Return to privileged EXEC mode.

Step 5 copy running-config startup-config (Optional) Save your entries in the configuration file.
