I have a puzzling situation with a DEChub.
The customer has a hub, with a UTP card and a DECbridge 90. Attached
to the UTPs are PCs and a server. The server has a UB card, and the
PCs have either UB or 3Com cards. This works fine.
Across the backbone is a UB Access One, with a bridge and UTP. On this
are also PCs and a server with a UB card. The PCs on the DEChub can
gain access to the server on the Access One, if they have a 3Com card.
However, if they have a UB card - they do not make it!
It would also seem that the PCs on the UB Access One can gain access to
the local server if they have a UB card or a 3Com card, but they can't
get to the server on the DEChub if they hace a UB card!
I never heard of bridges filtering on Manufacturer, so I guess it is
something else - any pointers?

It turned out that the management of the UB Hub was at fault.
Apparently, they set things up such that the UB Hub Bridge retrieved
its forwarding database from a management station, rather than learning
which side of it the Ethernet addresses were. This in conjunction with
the move on the network, and the simultaneous installation of the
DEChub bridge caused the confusing situation. When they put the UB
Bridge into dynamic learing mode, it all sprung into action.
So - the DECbridge 90 is exhonerated (and the customer thinks its
wonderful!).
