If you can, check the ICMP traffic on your LAN and see if it is very high. If you can see switch utilization and it is high you may have a virus that uses ICMP (ping)to spread.
Good luck.

You are missing the whole layer 3 part of the equation in reference to the routing table in reference to the router.
The MAC or layer 2 is for the interfaces. The IP address will get you to the host's router as long as the route is learned via algorithim or via static route. The first and last...
Your cable is not a low loss cable. There is a spec. for the length. I would say anything over 12-15 ft. is out of spec. Try 2 different lengths, 1 short and 1 long. If the loss is different, you have your fix!

"Proper" use of VLAN's will segment your broadcast domains and give you a certain level of security. It will change your IP scheme. Route between VLAN's, switch within VLAN's. It will also solve your host # problem.

You are using a cross connect cable I hope? With link lights
on I assume that you are. Does a reboot on the BB switch have any effect? Does Crisco...oops Cisco require more than one connection when running ISL? Try it in the standards based 802.3ad mode.

Can you shutdown the E1 WAN port? Is there anything connected to this port? I suspect the router will learn any
addresses that enter that port.
