Chapter 1
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
