Hi,
I'm doing some testing with wired dot1x and coming across possible future support issues. The supplicants are XP machines connecting to a 3750 switch.
The issue I see arising is when a user fails authentication, for whatever reason, how can you remotely be able to get a username/ password prompt to be redisplayed on the PC?
From my tests so far, once failed say for an incorrect password, the username password box never gets redisplayed unless the PC is either rebooted or physically disconnected and reconnected to the switch. OK, not the end of the world I know but I'd rather not have users pulling out and putting back in plugs as they are bound to end up in the wrong places.....you're probably way ahead of me here.
Anyway, bouncing the port from the switch didn't appear to make this happen. Clearing dot1x int didn't do anything either although it does if authentication has been successful as long as password cacheing has been turned off in XP.
As for working, everything is fine but it's when it doesn't work I can see problems arising for remote faulting. The Cisco docs don't cover this bit?
Anyone got any real life experience of this?
Cheers Bob
