avaya switch password reset stack

[Joseph_Crist]

I have a couple of Avaya 5500 series switches. I can no longer access one of them because I have forgotten the password. I heard it is possible to reset a the password without wiping the configuration. The process requires adding the switch to a stack and saving a new password to the switch's config. I have never performed a password reset using this method, and I would like to know where I can find a guide to perform a password reset without wiping the config.

Thanks,

Joe

There are two methods in which a user can regain CLI access without using the existing locally authenticated user name and password:

Method 1: Accessing the unit/stack using a backdoor password. This method will keep the current configuration intact. Once a user regains access to the CLI the existing password in the user profiles can be modified. You need to contact GTAC to get the back door password.

Method 2: Connect switch using console and enter Egineering menu to default the password. You also need to contact GTAC to get the Engineering password.

is the same applicable to ERS8010? I have forgot the password of ERS8010 but I want the configuration to be stable after the reset and need access.

HI Jong,

Please confirm I will not lose of my existing configuration using this option.

I'm seeing you mentioned model 8800 and 8600. does the same applicable for 8010 as well ?
