User Accounts and Privileges

The switch software supports three levels of privilege for users: USER, MANAGER, and SECURITY OFFICER. By default, the switch has one account (manager) defined with manager privilege and the default password friend. The commands that a user can execute depends on the user’s privilege level and whether the switch is operating in normal or security mode (see Normal Mode and Security Mode” on page 47). A USER level prompt looks like:

>

while a MANAGER prompt looks like:

Manager >

and a SECURITY OFFICER prompt looks like:

SecOff >

The MANAGER level has access to the full set of commands when the switch is in normal mode. When the switch is operating in security mode, users with MANAGER privilege cannot execute a subset of the commands known as the security commands (see Normal Mode and Security Mode” on page 47).
