I've run into weird problems like this when module heatsinks failed.
Traffic would pass so long as the overheating hardware didn't mess it
up. In my case, BGP would establish, but die out after TCP handshake.
I was able to ping with sufficiently small packets, but above a
certain size traffic would drop.
This was on a 6816-GBIC and the heatsink failure only affected one of
the FEs. If I moved to a port on the other FE, things would work
normally.
