Introduction to the CLI
A S4200G series Ethernet switch provides a command line interface (CLI) and
commands for you to configure and manage the Ethernet switch. The CLI is featured
by the following:
■
Commands are grouped by levels. This prevents unauthorized users from
operating the switch with relevant commands.
■
Users can gain online help at any time by entering the question mark “?”.
■
Commonly used diagnosing utilities (such as Tracert and Ping) are available.
■
Debugging information of various kinds is available.
■
The command history is available. You can recall and execute a history command
easily.
■
You can execute a command by only entering part of the command in the CLI, as
long as the keywords you input uniquely identify the corresponding ones.
Command
Level/Command View
To prevent unauthorized accesses, commands are grouped by command levels.
Commands fall into four levels: visit, monitor, system, and manage:
■
Visit level: Commands at this level are mainly used to diagnose network and
change the language mode of user interface, and cannot be saved in
configuration files. For example, the
ping
,
tracert
, and
language-mode
commands are at this level.
■
Monitor level: Commands at this level are mainly used to maintain the system and
diagnose service problems, and cannot be saved to configuration files. For
example, the
display
and
debugging
commands are at this level.
■
System level: Commands at this level are mainly used to configure services.
Commands concerning routing and network layers are at this level. You can utilize
network services by using these commands.
■
Manage level: Commands at this level are associated with the basic operation of
the system, and the system supporting modules. These commands provide
supports to services. Commands concerning file system, FTP/TFTP/XModem
downloading, user management, and level setting are at this level.
Users logging into a switch also fall into four levels, each of which corresponding to
one of the above command levels. Users at a specific level can only use the
commands of the same level and those of the lower levels.
Switching between
User Levels
A user can switch the user level from one to another by executing a related command
after logging into a switch. The administrator can also set user level switching
passwords so that users can switch their levels from lower ones to higher ones only
when they input the correct passwords.
