On the plus side, autoneg is mandatory in later versions of the
specs (1000Tx, 10g) IIRC, so maybe this nonsense will finally die?
If I understand 802.3 correctly, you must implement it, but you don't have
to use it, but I might not understand

The only places we disable autoneg in our network are to connect to same

Hi all,
Running up against an odd issue where we have a 3550 with an LX GBIC trying to
talk to a copper port on an ME3600 with a media converter in the middle. The
ME3600 side always shows as up; we disabled fault passthrough on the MC. The
LX GBIC on the 3550 side shows down/down with
If you have an fiber coupler (SC) you can loop TX to RX and verify that
link comes up on the 3550 side on your section of fiber. Also if media
converter has ability to do any internal loop tests (in either direction)
that would be good too.You may be able to plug an ethernet RJ45
loopback
