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.

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.

Figure 1-5 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.
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.

Figure 1-7 Log on the Switch
Key Authentication Mod e
1. Select the key type and key length, and generate SSH key.
Figure 1-8 Generate SSH Key
Note:
1. The key length is in the range of 512 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 1-9 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:
Figure 1-10 Download the Public Key
7
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.
Figure 1-11 SSH Connection Config

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
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
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.

Example
If you have set the password to access Privileged EXEC Mode from Use r E XEC
Mode:
T1500-28PCT>enable
Enter password：
T1500-28PCT#
service password-encryption
Description
The service password-encryption command is used to encrypt the password
when the password is defined or when the configuration is written, using the
symmetric encryption algorithm. Encryption prevents the password from being
readable in the configuration file. To disable the global encryption function,
please use no se rvice password-encryption command.
Syntax
service password-encryption
no service password-encryption
Command Mode
Global Configuration Mode
Example
Enable the global encryption function:
T1500-28PCT(config)# service password-encryption

enable password
Description
The enable password command is used to set or change the password for
users to access Privileged EXEC Mode from Us er EXEC Mode. To remove the
password, please use no enable password command. This command uses the
symmetric encryption.
Syntax
enable password { [ 0 ] password | 7 encrypted-password }
no enable password
Parameter
0 —— Specify the encryption type. 0 indicates that an unencrypted password
will follow. By default, the encryption type is 0.
password —— Super password, a string from 1 to 31 alphanumeric characters
or symbols. The password is case sensitive, allows digits, English letters (case
sensitive), underlines and sixteen special characters ( !$%'()*,-./[]{|} ). By default,
it is empty.
7 —— Indicates a symmetric encrypted password with fixed length will follow.
encrypted-password —— A symmetric encrypted password with fixed length,
which you can copy from another switch’s configuration file. After the encrypted
password is configured, you should use the corresponding unencrypted
password if you re-enter this mode.
Command Mode
Global Configuration Mode
User Guidelines
If the password you configured here is unencrypted and the global encryption
function is enabled in service password-en cr ypt i on, the password in the
configuration file will be displayed in the symmetric encrypted form.
Example
Set the super password as “admin” and unencrypted to access Privileged EXEC
Mode from User EXEC Mode:
T1500-28PCT(config)#enable password 0 admin
