We have upgrade our lease line from 4mb copper to 10mb fibre which meant we had to change our router.
The old router was a Cisco 2620 and the new Router is a Cisco 1841. Between the Cisco Router and our Cisco 3550 layer three switch is a bandwidth management box, which is an Allot NetEnforcer AC-402. On the old the old set-up using the Cisco 2620 everything worked fine. On the new set-up with the Cisco 1841 we are seeing a lot of CRC errors until the whole thing falls over. >From our side nothing has changed except the router which was supplied by the ISP. We did find out that the FE0/0 interface on the Cisco 1841 was set to auto, but this has now been set to Full Duplex 100mb which matches the Allot NetEnforcer. Taking the NetEnforcer out and connecting to the Cisco 1841 directly to the Cisco 3550 stops the errors, but as said before switching back to the Cisco 2620 also stops the errors. Any help would be appreciated.
