I came in this morning to work and it seems that the entire office was working at a snails pace (the 4506 that runs the office is in a Flat network config, only 40 devices all in the same domain). Everything runs at Gigabit or 100mbit speeds. It felt like everything had dropped to worse than 10mbit speeds! (Link speeds were still correct from the PCs, Gigabit PCs were still linked at Gigabit) I tried to access the switch from the console (the only way I have it setup to get console access) but I could not get a console (yes, the settings are correct, I even tried to recreate my hyperterminal config and tried using a different PC to connect just in case it was com-port issue). I can't get a console on the switch. I turned off the switch, and powered it back up, everything seems to work fine again. But I still can't get a console. I tried everything I could think of to get the console to work (set it to VT100 instead of Auto, tried Hardware FlowControl and No FlowControl). I didn't try a different cable, since I don't have one, but the cable has been in the same place for 3 years, and has never moved - it has always worked before as far as I know (it's been at least 6 months since I've logged in to it). Is the console port "dead"? Any help would be great.
I have this problem too.
