Alcatel Unleashed

Hello,

After a worm reload of the 6900 two ports haven't come up (no lights); all others came up fine. After moving the SFP to another port everything worked.
I still have another port not functioning and would like to troubleshoot it to avoid the problem in the future; not sure where to start, though..

Here is the interface in question:

The switch was synched and operational before the reboot, I've had no indications of any port problems.

I've seen this behavior when the fibers are dirty/bad. You could test this with a loop plug and see if the behavior changes.
