Cisco 3750 Switchport Intermittent Green/Amber

Last Modified: 2013-12-23
Hello, I have a (2) Cisco 3750's connected via trunked ports that traverse a radio shot between distant areas(the information is tunneled). We will lose connectivity to the far side portion of the network and I was given information that when this happens the trunked port will flash intermittent Green and Amber and we lose connectivity. Once the tech on the other end disconnects and reconnects the cable, the flashing will stop for awhile. Logs for the far end interface show only the manual disconnects.

My question is this: Is the intermittent flashing an indication that it has received some sort of bad input from the radio?

We are not seeing any problems with the network and work in a harsh environment, thus we think the radio equipment could be at fault, but have no way to be sure.

Thank you for any help!
