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

5

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 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 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

Privileged EXEC		Global Configuration
Mode		Mode

Interface Configuration Mode Interface gigabitEthernet Interface link-aggregation Interface range gigabitEthernet Interface range link-aggregation Interface vlan

……

VLAN Configuration Mode

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.

	Mode	Accessing Path			Prompt	Logout or Access the
						next 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

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

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. 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.
