Chapter 5. Introductions for CLI
5.1 What’s CLI and hierarchy level Mode
The MA-2040 command-line interface(CLI) is a software interface providing our another
way to set the parameters of equipment from the console or through a telnet network
connection. Before using them better a few of details will be introduced on four different
CLI hierarchy level modes which have different access rights:
$ User exec mode—The command prompt “>” shows you are in the user mode , in this
mode user can only use some simple commands to see the current configuration and
the status of the device, or enter the “ping” command to troubleshoot the network
connectivity.
$ Privileged exec mode—When you enter privileged mode ,the prompt will change to
“#” which user can do not only what is allowed in the user exec mode but also the new
additions like importing and exporting for files , system log , debug and so on .
$ Global configuration mode—The global configuration mode with prompt “<config>#”
allows user to add, set, modify and delete current configuration.
$ Interface mode—Prompt “<config-xx>” means in this mode we can set both IP address
and mtu for this interface.
Following is a relationship diagram about how to access or quit among the different
modes:
