Oook.
Found what it was.
Ive been using the GUI exclusivly for setting simple things, although I can drive the CLI as well.
What I found, was that somehow lo got set to the IP address of 151.142.223.30, the one I was trying to set for e0, or e1a-d with no sucess.
I wasnt able to remove the address from lo, so I just booted the sucker...and did it all by hand.
No problems.
Im yet to recreate the problem, but on my spare filer heads that are waiting patiently for cluster-failover, I will try to reproduce before I make any bug reports.
Also, Ive noticed a max input rate of about 20Mb/sec into the filter, then the CPU tops out on my F760.
I understand that the NVRAM can only process 16Mb at a time before the system really gums up, but I did expect a little more input performance.
Does anyone have any official or un-official comments on this?
