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 Enter button.

Figure 1-1 Run Window

2.Type in telnet 192.168.0.1 in the prompt cmd window and press Enter.

Figure 1-2 Type in the telnet command

3

3.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 1-3.

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.

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.

4

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.

5

Figure 1-7 Log on the Switch

Key Authentication Mode

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

8

5.Click Auth under the SSH menu in the left Category list, and click Browse to download the private key file to SSH client software and click Open.

Figure 1-12 Download the Private Key

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 1-13 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 fastEthernet, Interface

9

gigabitEthernet, Interface link-aggregation and some other modes, which is shown as the following diagram.

User EXEC 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.

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.

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 enable password command. Once password is configured, you are required 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

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.

Chapter 2 User Interface

enable

Description

The enable command is used to access Privileged EXEC Mode from User EXEC Mode.

Syntax

enable

Command Mode

User EXEC Mode

Example

If you have set the password to access Privileged EXEC Mode from User EXEC 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 service 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

14

enable password

Description

The enable password command is used to set or change the password for users to access Privileged EXEC Mode from User 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-encryption, 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

15

enable secret

Description

The enable secret command is used to set a secret password, which is using an MD5 encryption algorithm, for users to access Privileged EXEC Mode from User EXEC Mode. To return to the default configuration, please use no enable secret command. This command uses the MD5 encryption.

Syntax

enable secret { [ 0 ] password | 5 encrypted-password } no enable secret

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. The password in the configuration file will be displayed in the MD5 encrypted form.

5 —— Indicates an MD5 encrypted password with fixed length will follow.

encrypted-password —— An MD5 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 both the enable password and enable secret are defined, you must enter the password set in enable secret.
