Collision detection in my WAN
Hi,
There is a few time, my ISP told me that he noticed thath there are lot off collision in my wan network. As i see the cacti graph, every thing is fine in the bandwith. Some time, there are some pic but i identife the clients who are responsible.but the traffic is allowed. So i need help to how can i know that there are lot of collision. Is there a network monitor witch can help me ?
regards.

If ethernet hand off, check the WAN interface, are you running full duplex? If yes, i would have the ISP check their hand off for half duplex. A fiber to copper transceiver could also not negotiate properly and negotiate to half duplex.

See below the show interface commande for my routeur. Can you confirme that there is not collision? Or can you give me an explicit interpretation?
