I have an extreme switch recently configured, the optical port is not working very good. The link state is always active for a while(couple of hours to couple of days), and then change to link state "ready" and never come back until I power the whole switch down and up.
Recent log, related to this issue is :
09/29/2015 22:05:50.48
Port 45 link down - remote fault 09/29/2015 22:05:50.47 Port 46 link down - remote fault
09/29/2015 07:02:32.41 Port 45 link UP at speed 10 Gbps and full-duplex
09/29/2015 07:02:32.40 Port 46 link UP at speed 10 Gbps and full-duplex
09/29/2015 07:02:27.37 Port 45 link down - Local fault
09/29/2015 07:02:27.36 Port 46 link down - Local fault
Seems like the local fault can be recovered by the switch itself, but if the remote fault occurs, the port won't come back. Does anybody know what the remote fault really means?
Switch Type: X670V-48t
EXOS version: 15.2.2.7
detailed transceiver information on the extreme switch side:

On the other end, we are connecting to EXFO QA-805 10 gig optic ports with transceivers supported by them.
Thanks!
