And how was the fiber connected on the other end? It looks like problem with the autonegotiation. Or maybe flow control - is the remote device using fiber natively and going to copper through some intermediate converter? Those can cause such problems also. We need way more info to get this through troubleshooting. Or maybe they should involve TAC? -- "There's no sense in being precise when | Łukasz Bromirski you don't know what you're talking | jid:lbromir...@jabber.org about."
