Peculiar problem (collision) in Internet Router

Hi, we are facing peculiar problem in Router. In our Internet Router (2610) E0 we are getting lot of collisions & deferred. I had undergone the steps to solve the problem.

The Setup is link this:




1.Changed the Router E'net cable

2.Removed the Packeter & Connected to Switch then FW

3.Removed from Switch, Port Settings & Connected to Firewall directly with out any device intermediate

4.Changed the Router E'net cable

After all the changes nothing is working out. Then we changed the Router but problem is not resolved.

10 Mts E'net interface Report is below


Ethernet0/0 is up, line protocol is up

Re: Peculiar problem (collision) in Internet Router

Have you tried manually setting the ethernet interfaces on both sides to full duplex? Cisco autonegotiation often does not work well with other vendor ethernet interfaces.
