By default, the commands at level 3 are available to the users logging in to the AUX user interface. The
commands at level 0 are available to the users logging in to VTY user interfaces.
Commands fall into four command levels: visit, monitor, system, and manage, which are described as
follows:
z Visit level: Commands at this level are used to diagnose network, such as the ping, tracert, and
telnet command. Commands at this level cannot be saved in configuration files.
z Monitor level: Commands at this level are used to maintain the system, to debug service problems,
and so on. The display and debugging commands are at monitor level. Commands at this level
cannot be saved in configuration files.
z System level: Commands at this level are used to configure services. Commands concerning
routing and network layers are at system level. You can utilize network services by using these
commands.
z Manage level: Commands at this level are for the operation of the entire system and the system
supporting modules. Services are supported by these commands. Commands concerning file
system, file transfer protocol (FTP), trivial file transfer protocol (TFTP), downloading using
XModem, user management, and level setting are at administration level.
Refer to CLI Configuration for information about command level.
