Re: 2600 Cisco router error message

This is actually a symptom of another problem. Usually of bad cabling (possibly too long) or too many hubs deep in the network. It could also be a bad NIC on some system in the network.

I would first try changing the cabling between the router and the switch/hub that its connected to. After that, I would look deeper into your network to try and figure out if you have too many hubs deep in your network.

I would probably also verify the duplex and speed settings of the devices on the ports getting the late collisions.... I seem to remember problems of this type (though it shouldn't be late collisions), for some reason.
