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 and type in cmd in the Search programs and files window and press the Ente r
button.
Figure 1-1 Run Window
2. Type in telnet 192.168.0.1 in the prompt cmd window and press Enter.

Page 15
3. Type in the User name and Password (the factory default value for both of them are admin)
and press the Ente r button to enter User EXEC Mode , which is shown as Figure 1-3.
Figure 1-3 Log in the Switch
4. Type in enable command to enter Privileged EXEC Mode.
Figure 1-4 Enter into Priviledged EXEC Mode
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.
Ke y Authe ntication M ode : 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.

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.
Figure 1-6 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.

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 M ode : 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
a). Interface fastEthernet/gigabitEthernet: Configure parameters for a Fast/Gigabit
Ethernet port, such as Duplex-mode, flow control status.
b). Interface range fastEthernet/gigabitEthernet: The commands contained are the
same as that of the Interface fastEthernet/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.
11
Page 23
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.
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. In
default case, no password is needed. In Global Configuration Mode, you can configure password
for Admin level by e nable password command. Once password is configured, you ar e r equir ed to
enter it to access Privileged EXEC mode.
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 }
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
12
Page 24
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.
