Error on CatOS 6509: Native Vlan Mismatched

Hi, first of all thanks...my 6509 Catos core switch is now displaying the error:

"%CDP-4-NVLANMISMATCH:Native vlan mismatch detected on port 4/11"... now port 4/11 is not a trunk port so it shouldn't care about a native vlan (this is my understanding) unless it had 802.1Q configured but this is not the case, any ideas why all of the sudden I'm seeing this message?

Re: Error on CatOS 6509: Native Vlan Mismatched

you will see this even if you aren't trunking. It is a harmless message other than filling up the logs . To get rid of it obviously match the native vlans on each end . Other ways to get rid of this is to turn the logging level for cdp down to level 3 instead of 4 , it will still be happening but you won't see it in the logs .
