Hi,

We have a Nortel BayStack 470 switch configured with Radius
authentication. We also have a Cisco ACS version 3.3 server which works
as a Radius & TACACS+ server. Now when we press <Cntrl> + <Y> to log in
to the switch, it asks for a username and password. However, when we
type in the correct username and password it says "Access Denied from
RADIUS".

I also tried a WinRadius server and it didn't work.

Does anybody know how to get into this switch??

Thanks.
Deepu.

You can click "Ctrl + C" to interrupt booting and get into a boot
mode.
At this mode, press "i" to initialize config and log flash.
It's kind of a procedure of password recovery but you will lose any
configuraiton and log at this switch.

Is there any way to do this without losing the config of this switch,
as I am not aware of the existing configuration of this switch?

Thanks,
Deepu.

Unfortuately, this is the only one way to recover password by yourself.

Unless, you send this switch to Nortel and ask the tenical support
recover password without losing configuration. There is no well-known
backdoor at Nortel switches using new firmwares.

Is there any compatibility problem between the Nortel BayStack 470
switch and the Cisco ACS server v3.3. It appears that the Cisco ACS
server supports login from Nortel devices using Radius. When I check
the logs of the Cisco ACS server (Radius) it states that the user has
authenticated sucessfully, but the Nortel BayStack 470 gives "Access
Denied from RADIUS" message?
