While trying to track down some network issues this morning we came across a handful of ports on the passport (8600) that had their duplex settings set to auto-negotiate. As of Friday at 6:00 these ports were set to 100/full with autonegotiate disabled. I verified these settings before I left the office. Over the weekend we upgraded our database system, but made no changes to the passport itself. I have looked through the logs with Nortel and there is no indication of a change being made or even of one of the suspect ports bouncing. We are running 3.7.0.0 code. I can find no reason why this would suddenly go back to autonegotiation and only on a handful of ports. Other config on the passport seems ok. We aren't seeing any errors and the port is negotiated properly, but these are mission critical servers and our policy is to have them hard coded due to the possible issues with autonegotiation. Any ideas why this changed? And how?
