Hi,

I have reloaded a Cisco 3548-XL (Software V12.05) and for some reason I cannot get
Radius to Authenticate,

I recieve an authentication failed when using a domain account.  All other switches are working without problems on the same Windows IAS Server.


Any help appriciated.


Here is the config.

while logged in with enable access, I might change the line

aaa authentication login default group Radius_Servers local
to
aaa authentication login default group Radius_Servers

by removing "local", you will only see the radius debug

and then keeping the session open, configure two debugs

debug aaa authentication
debug aaa protocol radius

then retry accessing the device using a different terminal

Tried a different terminal.

Still fails to authenticate.

I would recheck that the IP address of the switch is in IAS as a RADIUS client, then recheck the shared secret
