Introduction of CLI command line

This chapter gives a detailed description of the WI-TEK Managed Switch CLI command line

interface The main contents are as follows

 Access switch CLI

 CLI mode introduction

 Introduction to command syntax

 Command line shortcuts

 History command

14 / 345

1.1 Access switch CLI

The CLI command line interface of the switch provides the interface for the user to manage

the switch The user can access the CLI command line interface of the switch through the

Console port and the Telnet two terminals The following are introduced separately

The main contents include

 Users access CLI through Console port

 Users access CLI through TELNET

1.1.1 Users access CLI through Console port

Figure 1 - Console cable

Cisco part number 72-3383-01 (Console Cable)

The operating procedure is as follows

First step Connect the serial port of PC with the Console port of the switch by configuring

the cable The following diagram

15 / 345

Second steps Start the terminal emulation program on the PC machine (such as the super

terminal of Windows) Configuring communication parameters of terminal emulation program

The communication parameters of the terminal are configured as follows

Baud rate 38400

Data bits 8

Parity check nothing

Stop bit 1

Data stream control nothing

The communication parameters configuration of the super terminal is shown below

16 / 345

Third steps Start switch After the Switch is started, the CLI prompt will be displayed on

the terminal (the default is Switch >) Users can enter commands at this prompt This allows the

user to access the CLI of the switch

1.1.2

Users access CLI through TELNET

The user can access the switch through the port of the switch

The IP address of the port of the switch defaults to 192.168.0.1 The steps to access the

switch through the port are as follows

First step Connect Ethernet port and switch port of PC through Ethernet cable The

following diagram

Second steps Set the IP address of the Ethernet port of the PC machine The IP address

must be in the 192.168.0.0/24 segment (such as IP address 192.168.0.100) Judging the

connectivity between PC and switch through Ping 192.168.0.1

Third steps If the PC is connected to the switch Then Telnet 192.168.0.1 enters the Telnet

terminal interface The following diagram

17 / 345

Fourth steps If the system does not have a password, the Telnet interface goes directly to

the CLI, and the CLI prompt appears (default is Switch >). If the system sets the password, you

need to enter the password on the Telnet interface to enter the CLI.

Two points should be paid special attention to

 The IP address of the switch port is based on the VLAN three layer interface Before

accessing the switch You must set the IP address of a VLAN interface The default IP

address of VLAN1 is 192.168.0.1 It can be used directly The IP address of the

VLAN interface can be configured through the Console port

 The user accesses the switch through the port You can connect PC and ports directly

through Ethernet cable You can also connect through a network You just need PC to

communicate with one of the VLAN switches

1.2 CLI mode introduction

The main contents include

 The role of CLI model

 Identification of CLI mode

 Classification of CLI patterns

18 / 345

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

19 / 345

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

CLI prompt Switch# identifies privileged mode Switch identifies the host, and #

identification model

The CLI prompt (config-ge1/1)# identifies the interface configuration mode and is

configured with ge1/1 port Switch identifies the host, and (config-ge1/1) # identification

model

The CLI prompt Switch(config-vlan2)# identifies the interface configuration mode And

configure the vlan2 interface Switch identifies the host, and (config-vlan2) # identification

model

1.2.3 Classification of CLI patterns

The CLI model is divided into four categories: general mode, privileged mode, global

configuration mode and configuration sub pattern, while the configuration sub model is composed

of many CLI modes.

Ordinary users can only access common patterns, and privileged users can access all of the

CLI patterns

Console and Telnet terminals first enter the common mode, enter the enable command in the

normal mode, and successfully verify the password, then enter privileged mode On the Telnet

terminal, ordinary users can only stay in the ordinary mode and cannot enter privileged mode

Enter configure terminal in privileged mode CLI mode enters global configuration mode In

global configuration mode, you can enter the relevant commands and enter each configuration sub
