Gert,

I seem to remember us adding this.

CDP and ODR Support for ATM PVCs

This feature introduces support for the Cisco Discovery Protocol (CDP) over ATM point-to-point permanent virtual circuits (PVCs). Prior to this release, CDP discovery messages were not supported over ATM interfaces.

<snip>

Looks like it went in 12.2(8)T and later so 12.3 should have it.
