Timeout problem

[mainstreetexpress]

Hi
Currently I have a point to point 10bT ethernet link i.e. /30 between a 7200 and a 2610 (ISP to customer). Now I am noticing a timeout every 20-30 seconds. Currently there is about 1Mbps traffic across the link according to MRTG but I'm noticing about 30-50 collisions per second!

Can anyone suggest any reason for this or what else to look out for in trying to diagonse this problem?

Any help would be great

hai
this problem is due to your internal network traffic and bandwidth.also please check your last mile by loop back test(higher resistance in cable may be another cause)

Hi
The link between the 7200 and the 2610 is about 5 metres using standard cat5 cabling between the two ethernet ports. I am looking in from the ISP side (7200) to the customer side(2610).
I am pinging the WAN side of the customers router.

How would the customers internal traffic affect this link?

Have you checked the interface counters?

sounds like you have a bad patch cable, or a port on one router or the other. Ethernet devices should listen for traffic befor sending a packet! one of your devices is not listening to the traffic before sending. as there is no way the two routers will try to send at the same instance that many times a second. Have you tested your cable? if you are experiancing cross talk it could be seen by the routers as collisions. First test cable or use a known good one. then try another port if you have one.
