[comp.sys.dec] Lan Bridge 150 problem?

markat@cyrano (Mark Tassinari) (11/08/90)

We have a number of bridges that were recently upgraded to LB150s.  Soon
after the upgrade one of the bridges would occasionally get into a weird
state where it would stop forwarding packets and no longer respond
to RBMS commands. All other outward indications were that the bridge was
fine - it was seeing packets on both ports and that it was in forwarding 
mode.  The only way to make it begin bridging again was to power it off
then on.

After the second occurance, the bridge was replaced.  When the new bridge
failed all the related hardware was checked and verified to be working
properly.  Today, this same behavior has occured in a another LB150 on a 
network across the site that is connected to the same backbone.  Now its
begining to look like the cause is on the network.  A Sniffer has 
revealed nothing unusual on the backbone, but then the data captured did
not coincide with one of the bridges failing.

Can someone out there please tell me that they've seen this and point me
to a solution?
