Passwords
The following section describes various ways to recover forgotten passwords.
Symptom User forgot password.
Probable cause and recommended action
If you know the root password, you can use this procedure to recover the password for the default
accounts of user, admin, and factory. If you do not know the root password, you must contact your
service support provider to recover admin passwords.
Recovering passwords
1. Open a CLI connection (serial or Telnet) to the switch.
2. Log in as root.
3. Enter the command for the type of password that was lost:
passwd user
passwd admin
passwd factory
4. Enter the requested information at the prompts.
Symptom Unable to log in as root password.
Probable cause and recommended action
To recover your root password, contact your switch service provider.
Symptom Unable to log into the boot PROM.
Probable cause and recommended action
To recover a lost boot PROM password, contact your switch service provider. You must have
previously set a recovery string to recover the boot PROM password.
This does not work on lost or forgotten passwords in the account database.
