We recently converted our 330 and 540 from FDDI to 100BaseT. We found that we had to manually force both the 100BaseT card in the toaster and the specific port on our Cabletron Smart Switch 9000 to 100BaseT-FD. For the 100BaseT card, it was simply changing the auto to 100tx-fd:
ifconfig e5 `hostname`-e5 mediatype 100tx-fd netmask 255.255.248.0
Funny how that auto-negotiation thing never really works, and how much it really affects performance.

Hi Warren,
Were you using autonegotiation against full duplex? If so, that isn't going to work by the specs for auto-negotiation. I think the designers of the protocol assumed if your nic (or switch port) was too old to support autonegotiation, then it was to old to support full duplex.
So auto <--> half works and auto <--> auto works but auto <--> full won't by specification.
That is my understanding, at least. Feel free to correct me if I am wrong.

I should clarify... by "won't work", I mean it will negotiate at the wrong media type. The 'auto' side will negotiate to 'half' when connected to a full duplex port.

That is correct. No matter what kind of switch you are connected to, you should force but sides to Full duplex.

This gets even better -- our 720 hated explicit modes talking to our Cabletron SSR-8 (the former YAGO switch-router). We had run into many problems with auto negotiation on other parts of our network and when we brought the 720 online we set it to 100tx-fd and it seemed to run at 10/half duplex. When our NetApp SE came out, all we could do to fix the problem was change back to auto negotiation.
