The ACE supports the following special characters in a password Note that the ACE encrypts clear text passwords in the running-config. For example, to create a user named user1 that uses the clear text password mysecret_801, enter the following command: switch/Admin(config)# username user1 password 0 mysecret_801 To remove the username from the configuration, enter the following command: switch/Admin(config)# no username user1 Resetting the Administrator CLI Account Password If you forget the password for the ACE administrator account and cannot access the ACE, you can recover the admin password during the initial bootup sequence of the ACE.
