Knowing my luck, within a week of re-enabling this circuit, it'll start
flapping again.

At a previous $dayjob, we employed a guy that was a bona fide optical guru.
He had effectively memorized the 400+ page Nortel 6500 operating guide, and
some of the hardware vendors would call him for advice when their TACs
couldn't figure a problem out. Allegedly, he was the person who discovered

Ask them for an RFO report. They should be able to explain the diagnostics and
reason for the original flapping. It's quite possible they found a problem
somewhere on the path with a DWDM multiplexor or something. That wouldn't need
any card replacement on your prem.

I have a wave transport vendor that suffered issues twice about ten days apart,
causing my link to flap a bunch. I put in a ticket on the second set of
occurrences. I was told that there was a card issue identified and would be
notified when the replacement happened. Ticket closed.
