Hi,
We have two 10GB links using the Cisco 10GB LR x2 gbics in a 8 port 10GE card (WS-X6708-10GE), one which is showing high optical loss, while the other is fine.

Te2/2 29.0 0.00 5.2 -2.6 -3.5
When we switch the links the loss doesn't follow the fibre, and swapping out the end gbics also does not resolve the issue. We are at a loss on how to resolve.
Has anyone else come across this?
Thanks
David
