Hi!
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.
Bestregards!

Hi,
What is the speed/duplex configuration on the switch side.

Hi!
The siwtch is configured in auto.

Run this on the port connecting to the cpe.
#test cable-diagnostics tdr interface (port)
Then run:
#show cable-diagnostics tdr interface (port)
Make sure that it says normal under pair status. I think if it runs fine under 10 half that means you may have issue with cable as its not running in full duplex.
Heres a example of one of my ports.
TDR test last run on: June 22 10:57:30
Interface Speed Local pair Pair length Remote pair Pair status
--------- ----- ---------- ------------------ ----------- --------------------
Gi1/0/1 1000M Pair A 28 +/- 4 meters Pair A Normal
Pair B 27 +/- 4 meters Pair B Normal
Pair C 28 +/- 4 meters Pair C Normal
Pair D 28 +/- 4 meters Pair D Normal
Then I would suggest making sure that the port on the cpe is mdix (auto sensing).
