I'm connecting a 3560 switch to a CPE (from Alvarion). When the CPE is set to autonegotiate all the posible transmisions modes and speed, the port of the switch starts blinking green-ambar. If I force the CPE to 10 Mbps and Half, the port stops blinking and I have conectivivity.
I have other 10 siwtch with the same configuration and only two of them present the same problem.
If I perform the comand: show controllers ethernet-controller phy detail, I obtain this (see attachment)
In the section Port Status Register we can see: Error 1.
Could this be problem of the cable? What are the posible reasons why this "Error 1"?
Any help, will be appreciate.
