1.2.1 The role of CLI model

There are two main functions of the CLI model：

 Convenient classification of users，Prevent unauthorized users from using CLI illegally。

Users can be divided into two levels，That's the two category：Common users and privileged

users。

Ordinary users can only see some of the running state of the switch，Use only display

commands。

Privileged users can not only view the running state of the switch, but also maintain and

configure the switch to change the behavior of the switch。

 Convenient for users to configure switches

Switches have a lot of configuration, and if you put all the configuration in one mode, it's

very inconvenient for the user to use. To this end, the establishment of multiple modes on the CLI,

the similar commands placed in a mode, user-friendly understanding and use. For example, put the

commands associated with VLAN in the VLAN configuration mode.Put the interface related

commands in the interface configuration mode。

1.2.2 Identification of CLI mode

The CLI prompt is the identity of the CLI mode，When the user is using CLI，By looking at

the CLI prompt, you know the CLI model that you're currently in。

The CLI prompt consists of two parts，Part identifies the host，Another part identifies

patterns。

The host part of the CLI prompt uses the hostname of the system，The host name of the

system is configurable，the default is Switch，So the CLI prompt defaults to Switch，the CLI

descriptor mentioned later generally uses the default host name。

The schema section in the CLI prompt is not configurable，each pattern has its own

corresponding pattern string，some pattern strings are immutable，some pattern strings are

mutable。If the pattern string of the VLAN configuration pattern is fixed, the pattern string of the

interface configuration pattern is variable。

For example：
