z
You can execute a command by entering part of the command in the CLI as long
as the keywords you enter do not conflict those of other commands.
1.2 Command Level/Command View
To prevent unauthorized accesses, commands are grouped by level.
Commands fall into four levels: visit, monitor, system, and manage.
z
Visit level: Commands at this level are mainly used to diagnose network and
switch the language mode on the user interface, and they cannot be saved in
configuration files. Such commands include ping, tracert, and language-mode.
z
Monitor level: Commands at this level are mainly used to maintain the system and
diagnose service faults, and they cannot be saved in configuration files. Such
commands include display and debugging.
z
System level: Commands at this level are mainly used to configure services.
Commands concerning routing and network layers are at this level. These
commands can be used to provide network services directly.
z
Manage level: Commands at this level are associated with the basic operation
modules and support modules of the system. These commands provide supports
for services. Commands concerning file system, FTP/TFTP/XModem
downloading, user management, and level setting are at this level.
Users logging in to a switch also fall into four levels, which respectively correspond to
the command levels. Users at a specific level can only use the commands at the same
level or lower levels.
1.2.1 Switching between User Levels
You can switch from one user level to another by executing a related command and set
a password for the switching as required after logging in to a switch.
