cdp neighbor Question ?

CCIE_2011

Hi all ....
CDP ,in switches only as we all know, uses the lowest SVI in its advertisements traffic to other cisco devices.
How can we choose a specific svi to be advertised in the CDP traffic?

Maybe he thought it meant the time (military) not the date!

I tried to disable cdp at svi. It seems impossible.
Is that what you are saying ?

CDP uses vlan 1, if you disable vlan 1 on the trunk, cdp will still use vlan 1.
The link provided didn't explain this.

CDP is not supported on an SVI. They are logical interfaces inside the switch so what device would they exchange a CDP frame with? Itself?

What is it you are trying to do?
