I've thought about half/full duplex issues on the 450's ethernet but its set correctly on the netapp and I've read that the 450 does support full-duplex anyway.
Any ideas as to why my 450 doesn't like the switch?
considering i wasted a substantial chunk of this week on exactly that issue, i'd say *check the duplexity*.
yes, all sorts of things are happy running full-duplex, but there doesn't seem to be a rock-solid protocol for autodetection of duplex state yet. even our (not particularly cheap) CISCO catalyst switch can't do it reliably.
if you can't interrogate your switch, and it doesn't have duplex-state idiot lights, you might try switching the toaster back to half-duplex and seeing if that improves matters.
i would also look at the output of "netstat -i" on the toaster; if the ratio of ierrs to ipkts is more than about 1:10^5, i'd also consider that strong evidence of a duplexity problem.
hth.
