really? what switch / fw version? That's one of the ones I did play with and had no issue, at least on 8030:I tried the "dd temp-fanspeed" command with "?" and tab to see if FastIron had anything. I wasn't expecting anything, only curious. It didn't and instead I had to go physically reset the switch. The smart thing would have been to try on a switch I wasn't actively using, oh well.
telnet@FCX2#dd temp-fanspeed DECIMAL fan speed 1 or 2 DECIMAL gap between two readings (sec) auto fan speed in auto mode
