CDP: Disable

colmgrier · ‎02-17-2009

Is it possible to disable cdp under an SVI on a Catalyst 6500 switch. tried running the command but still no sucess. CDP is globally enabled.

interface vlan 100

no cdp run

I have not tried it but isn't the command to disable cdp under an interface:

no cdp en

CDP is not a layer 3 function so you would have to disable it on the port interfaces.

The "no cdp run" is for Global configuration only (turns off CDP to the appliance).

You can over-ride this command by going into the interface and do the "no cdp enable".

For example.

config t

no cdp run < -- Turns OFF CDP to the appliance.

!

interface FastEthernet 2/12

cdp enable < --- Enable CDP to this AND ONLY this interface.

Does this help?

Hi Leo,

exactly my point in my posting earlier that he ought to use no cdp en under the interface.
