[c-nsp] selectively suppress CDP vlan warnings?

Hi,
one of our switches is pegging me with warnings like this one:
Oct 27 23:51:29 sw2-int.XX.XX 5882: %CDP-4-NATIVE_VLAN_MISMATCH: Native VLAN
mismatch discovered on FastEthernet0/1 (1), with SCAxxxxx(YYY-ZZ) 7/41 (81).
- which I am aware of, and it's perfectly fine that way - the switch
that is sending out all the complaints is a "slave switch", which has
no VLANs at all, all the ports in VLAN 1 (2950, 12.1(22)EA4).
To get rid of the warnings, I see two possible approaches, that I both
do not like very much:
- switch off CDP (or go to v1 globally on the 6509 on the other end)
- we think CDP is useful, have it enabled on all "internal" links, and
CDP v2 carries more useful stuff around
- move all ports plus management VLAN to vlan 81
- lots of effort, for minor gain
what I'd *really* like to see is an option
" no cdp warnings vlan-mismatch "
but as far as I'm aware, it doesn't exist.
Anything I'm overlooking here?
