Hi All,

I am having some weird VTP issue at the moment where one of the 4
switches wont join the VTP domain. I have tired reloads of the switch,
deleting the vlan.dat file and even erasing the whole config and
starting again. But still it doesnt join the domain.

Does anyone have any suggestions?

Thanks

Az
