I purchased two 3725 routers from ebay and for some strange reason the fa0/0 & fa0/1 interfaces will not remain up\up.
This is when conecting to a 3550. I've connected the interfaces to a laptop and the ports go active at once - but once I connect the interfaces to a switch they immediately go down. I've hardcoded the switch ports with no success.
I've hardcoded the duplex and speed on the routers and the interface goes up\up then down\down. Autosense produces no positive results ...
Any reason WHY this can be happening ... its very odd!!!
