Re: [Testbed-admins] query regarding MIB compatibility with the experiment switch

[Robert P Ricci <ricci@cs.utah.edu>]

We actually don't use VTP or any of the stacking protocols at all. It
just happens that the OIDs we use for 'regular' VLAN creation and a few
other operations are in the VTP and STACK MIBs. This is why I think that
it's likely that if you give these OIDs to Cisco, they will be able to
tell you of another MIB that provides the same functionality.
