Problem with my cisco catalyst4007

hello, sorry to bother you all, really need your kind help. Currently we are using catalyst4007 and just upgarded it with new 48 ports 10/100/1000 module. But after the IOS upgrade to 12.2 and installation of the new module a problem came out. When we try to link this Catalyst4007 to our cisco 2950 the error came out - DOMAINMISMATCH: Unable to perform trunk negotiation on port Gi2/01 because of VTP domain mismatch.What is the problem actually, we really need your kind advice in order us to solve this problem. Thnak you

Re: Problem with my cisco catalyst4007

will you please post your trunking configuration as well as vtp status?

Re: Problem with my cisco catalyst4007

This message means that the two ports involved in trunk negotiation belong to different VTP domains. Trunking is possible only when the ports involved belong to the same VTP domain.

Ensure that the two ports that are involved in trunk negotiation belong to the same VTP domain.

so change you domain name or make your domain name same...

rate this post if it helps

Re: Problem with my cisco catalyst4007

You "must" match the vtp domain name on each switch in order for the trunk to come up . Cisco has never made the parameters on this function consistent , some switches you do not have to match the domain names (catos) and others like the 4506 you must match the domain names...
