Chapter 1 Using the CLI
1.1 Accessing the CLI
You can log on to the switch and access the CLI by logging on to the switch remotely by a Telnet
through an Ethernet port. To log on to the switch by a Telnet connection, please take the following
steps:
1. Make sure the switch and the PC are in the same LAN.
2. Click Start →Run to open the Run window.
Figure 1-1 Open the Run window
3. Type “cmd” in the prompt Run window as Figure 1-2 and click OK button.
Figure 1-2 Run Window

4
4. Type “telnet 192.168.0.1” in the command prompt shown as Figure 1-3, and press the Enter
button.
Figure 1-3 Connecting to the Switch
5. Type the User name and Password (the factory default value for both of them is admin) and
press the Enter button, then you can use the CLI now, which is shown as Figure1-4.
Figure 1-4 Log in the Switch
1.2 CLI Command Modes
The CLI is divided into different command modes: User EXEC Mode, Privileged EXEC Mode,
Global Configuration Mode, Interface Configuration Mode and VLAN Configuration Mode.
Interface Configuration Mode can also be divided into Interface gigabitEthernet, Interface
link-aggregation and some other modes, which is shown as the following diagram.
The following table gives detailed information about the Accessing path, Prompt of each mode and
how to exit the current mode and access the next mode.

5
Mode Accessing Path Prompt Logout or Access the next
mode
User EXEC
Mode
Primary mode once it
is connected with the
switch.
TL-SG2424P>
Use the exit command to
disconnect the switch.
Use the enable command to
access Privileged EXEC mode.
Privileged
EXEC Mode
Use the enable
command to enter
this mode from User
EXEC mode.
TL-SG2424P#
Enter the disable or the exit
command to return to User EXEC
mode.
Enter configure command to
access Global Configuration
mode.
Global
Configuration
Mode
Use the configure
command to enter
this mode from
Privileged EXEC
mode.
TL-SG2424P(config)#
Use the exit or the end command
or press Ctrl+Z to return to
Privileged EXEC mode.
Use the interface
gigabitEthernet port or interface
range gigabitEthernet port-list
command to access interface
Configuration mode.
Use the vlan vlan-list to access
VLAN Configuration mode.
Interface
Configuration
Mode
Use the interface
gigabitEthernet port
or interface range
gigabitEthernet
port-list command to
enter this mode from
Global Configuration
mode.
TL-SG2424P(config-if)#
or
TL-SG2424P(config-if-range)#
Use the end command or press
Ctrl+Z to return to Privileged
EXEC mode.
Enter the exit or the # command
to return to Global Configuration
mode.
A port number must be specified
in the interface command.
VLAN
Configuration
Mode
Use the vlan vlan-list
command to enter
this mode from
Global Configuration
mode.
TL-SG2424P(config-vlan)#
Use the end command or press
Ctrl+Z to return to Privileged
EXEC mode.
Enter the exit or the # command
to return to Global configuration
mode.
Note:
1. The user is automatically in User EXEC Mode after the connection between the PC and
the switch is established by a telnet connection.
2. Each command mode has its own set of specific commands. To configure some
commands, you should access the corresponding command mode firstly.
Global Configuration Mode: In this mode, global commands are provided, such as
the Spanning Tree, Schedule Mode and so on.
Interface Configuration Mode: In this mode, users can configure one or several
ports, different ports corresponds to different commands

6
a). Interface gigabitEthernet: Configure parameters for an Ethernet port, such as
Duplex-mode, flow control status.
b). Interface range gigabitEthernet: The commands contained are the same as that
of the Interface Ethernet. Configure parameters for several Ethernet ports.
c). Interface link-aggregation: Configure parameters for a link-aggregation, such as
broadcast storm.
d). Interface range link-aggregation: Configure parameters for multi-trunks.
e). Interface vlan: Configure parameters for the vlan-port.
Vlan Configuration Mode: In this mode, users can create a VLAN and add a
specified port to the VLAN.
3. Some commands are global, that means they can be performed in all modes:
show: Displays all information of switch, for example: statistic information, port
information, VLAN information.
history: Displays the commands history.
1.3 Security Levels
This switch’s security is divided into two levels: User level and Admin level.
User level only allows users to do some simple operations in User EXEC Mode; Admin level
allows you to monitor, configure and manage the switch in Privileged EXEC Mode, Global
Configuration Mode, Interface Configuration Mode and VLAN Configuration Mode.
Users get the privilege to the User level once logging in by Telnet. However, Guest users are
restricted to access the CLI.
Users can enter Privileged EXEC mode from User EXEC mode by using the enable command.
1.4 Conventions
1.4.1 Format Conventions
The following conventions are used in this Guide:
Items in square brackets [ ] are optional
Items in braces { } are required
Alternative items are grouped in braces and separated by vertical bars. For example: speed
{10 | 100 | 1000 }

7
Bold indicates an unalterable keyword. For example: show logging
Normal Font indicates a constant (several options are enumerated and only one can be
selected). For example: switchport type { access | trunk | general }
Italic Font indicates a variable (an actual value must be assigned). For example: bridge
aging-time aging-time
1.4.2 Special Characters
You should pay attentions to the description below if the variable is a character string:
These six characters ” < > , \ & can not be input.
If a blank is contained in a character string, single or double quotation marks should be used,
for example ’hello world’, ”hello world”, and the words in the quotation marks will be identified
as a string. Otherwise, the words will be identified as several strings.
1.4.3 Parameter Format
Some parameters must be entered in special formats which are shown as follows:
MAC Address must be entered in the format of xx:xx:xx:xx:xx:xx
One or several values can be typed for a port-list or a vlan-list using comma to separate. Use
a hyphen to designate a range of values, for instance 1, 3-5,7 indicates choosing 1,3,4,5,7.
The port number should format as 1/0/3, meaning unit/slot/port. The unit number is always 1,
and slot number is always 0 and the port number is a variable (an actual value must be
assigned).
