Hey Don,
Interesting problem.. Have you tried clearing the arp cache on the 2924? I
assume that the hosts connected to the hub are in the same subnet as the
ones on the switch? Any Vlans setup on the switch? Any access-lists setup?
Finally, have you tried erasing the config and starting from scratch on it?
Don't know too much about the Bay hubs so can't really offer any advice on
it. Let me know if you were able to fix it and how.
Hope that helps
Russ..
