Yeah, seems to fit the situation, but even if that's true, you're going to
get a problem when you make the first change to either of the switches. The
configuration revision will increment and the other switch will then be
updated with all the VLAN info from the one which has had the change (losing
any VLANS which did not already exist on both).
Nelluri - Did the VLAN's disappear immediately, or is it possible that a
change may have been made to one of the switches which incremented the
revision and screwed things up?
Either way I think the only way is to configure all VLANS on the switch with
the highest revision.
