You can use a local database on each switch to authenticate management sessions. An account can be disabled or enabled locally using read/write access. Even all administrative privileged accounts and user privileged accounts can be disabled. Lawful-Intercept account will be disabled under user privileged option. When all administrative accounts will be disabled locally, a warning will be shown to use failsafe account, if necessary.
The local database stores user names and passwords and helps to ensure that any configuration changes to the switch can be done only by authorized users.
You can increase authentication security using Secure Shell 2 (SSH2). SSH2 provides encryption for management sessions. For information about SSH2, see Secure Shell 2.
