Nortel 5510 password recovery via Device Manager
« on: January 22, 2015, 08:55:32 AM »
Hello,

I have a bs5510 switch stack that we don't know the ssh or local console password to however device manager works fine.

I have TFTP 'd the asci config off the switch and was thinking I could edit the following lines in the config file then TFTP upload the config file back onto the switch:

cli password stack serial none
cli password stack telnet none
cli password stack read-only public
cli password stack read-write private
telnet-access enable

My question regarding a TFTP upload of a config to a switch is whether the switch will reboot, or does it just merge the config and remain in operational?

I also thought an alternative would be to create a user on a RADIUS server, then using DM configure the switch to use RADIUS for user authentication, then login to the switch with the RADIUS credentials and change the local passwords.

Thanks for reading.
Your thoughts appreciated.

it will just merge in the changes.  the switch wont reboot.
 you can actually just TFTP a file with those security setting. you don't need to TFTP the entire config.

Thanks for the reply Paul, I don't have a test switch to work on so providing there are no gotchas, I think I'll go ahead and do this under Change Control.
Best regards.
