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 or
SSH connection through an Ethernet port.
1.1.1. Logon by Telnet
To log on to the switch by a Telnet connection, please take the following steps:
1. Click Start → Run to open the Run window, and type in telnet 192.168.0.1 in the prompt Run
window as Figure 1-1 and click OK.
Figure 1-1 Run Window
2. Type in the User name and Password (the factory default value for both of them are admin)
and press the Enter button to enter User EXEC Mode , which is shown as Figure 1-2.
Figure 1-2 Log in the Switch
3. Type in enable command to enter Privileged EXEC Mode.
Figure 1-3 Enter into Priviledged EXEC Mode
3
1.1.2. Logon by SSH
To log on by SSH, a Putty client software is recommended. There are two authentication modes to
set up an SSH connection:
Password Authentication Mode: It requires username and password, which are both admin by
default.
Key Authentication Mode: It requires a public key for the switch and a private key for the SSH
client software. You can generate the public key and the private key through Putty Key Generator.
Note:
Before SSH login, please follow the steps shown in Figure 1-4 to enable the SSH function through
Telnet connection.
Figure 1-4 Enable SSH function
Password Authentication Mode
1. Open the software to log on to the interface of PuTTY. Enter the IP address of the switch into
Host Name field; keep the default value 22 in the Port field; select SSH as the Connection
type.
4
Figure 1-5 SSH Connection Config
2. Click the Open button in the above figure to log on to the switch. Enter the login user name
and password to log on the switch, and then enter enable to enter Privileged EXEC Mode, so
you can continue to configure the switch.
Figure 1-6 Log on the Switch
5
Key Authentication Mode
1. Select the key type and key length, and generate SSH key.
Figure 1-7 Generate SSH Key
Note:
1. The key length is in the range of 256 to 3072 bits.
2. During the key generation, randomly moving the mouse quickly can accelerate the key
generation.
6
2. After the key is successfully generated, please save the public key and private key to a TFTP
server.
Figure 1-8 Save the Generated Key
3. Log on to the switch by Telnet and download the public key file from the TFTP server to the
switch, as the following figure shows:
7
Figure 1-9 Download the Public Key
Note:
1. The key type should accord with the type of the key file.
2. The SSH key downloading can not be interrupted.
4. After the public key is downloaded, please log on to the interface of PuTTY and enter the IP
address for login.
8
Figure 1-10 SSH Connection Config
5. Click Browse to download the private key file to SSH client software and click Open.
Figure 1-11 Download the Private Key
9
6. After successful authentication, please enter the login user name. If you log on to the switch
without entering password, it indicates that the key has been successfully downloaded.
Figure 1-12 Log on 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 Ethernet, Interface
link-aggregation and some other modes, which is shown as the following diagram.

the interface command.
Use the end command or press
Ctrl+Z to return to Privileged EXEC
mode.
Enter the exit command 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/SSH 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.
11
Interface Configuration Mode: In this mode, users can configure one or several ports,
different ports corresponds to different commands
a). Interface gigabitEthernet: Configure parameters for an Ethernet port, such as
Duplex-mode, flow control status.
b). Interface range gigabitEthernet: 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: display all information of switch, for example: statistic information, port information,
VLAN information.
history: Display 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/SSH. However, Guest users are
restricted to access the CLI.
Users can enter Privileged EXEC mode from User EXEC mode by using the enable command. In
default case, no password is needed. In Global Configuration Mode, you can configure password

1.4 Conventions
1.4.1 Format Conventions
The following conventions are used in this Guide:

Items in braces { } are required
Alternative items are grouped in braces and separated by vertical bars. For example: speed
{10 | 100 | 1000 }
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: mode {dynamic | static | permanent}
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 enter 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,1/0/1,1/0/3-5,1/0/7 indicates choosing
port 1/0/1,1/0/3,1/0/4,1/0/5,1/0/7.
