Chapter 1 Using the CLI

1.1 Accessing the CLI

You can log on to the switch and access the CLI by the following two methods:

1.Log on to the switch by the console port on the switch.

2.Log on to the switch remotely by a Telnet or SSH connection through an Ethernet port.

1.1.1 Logon by a console port

To log on to the switch by the console port on the switch, please take the following steps:

1.Connect the PCs or Terminals to the console port on the switch by a provided cable.

2.Click Start →All Programs →Accessories→Communications →Hyper Terminal to open the Hyper Terminal as the Figure 1-1 shown.

Figure 1-1 Open Hyper Terminal

3.The Connection Description Window will prompt as Figure 1-2 shown. Enter a name into the Name field and click OK.

4

Figure 1-2 Connection Description

4.Select the port to connect in Figure 1-3, and click OK.

Figure 1-3 Select the port to connect

5.Configure the port selected in the step above as the following Figure 1-4 shown. Configure Bits per second as 38400, Data bits as 8, Parity as None, Stop bits as 1,

Flow control as None, and then click OK.

6.The DOS prompt ”TL-SG5428>” will appear after pressing the Enter button as Figure 1-5 shown. It indicates that you can use the CLI now.

Figure 1-5 Log in the Switch

1.1.2 Logon by Telnet

To successfully create Telnet connection, firstly CLI commands about configuring Telnet login mode, login authentication information and Privileged EXEC Mode password should be configured through Console connection.

Telnet login has the following two modes. You can choose one according to your needs:

6

Login local Mode: It requires username and password, which are both admin by default.

Login Mode: It requires no username and password, but a connection password is required.

Note:

1.Before Telnet login, you are required to configure Telnet login mode and login authentication information through Console connection. The relevant CLI commands should be entered in the prompted DOS screen shown in Figure 1-5 Log in the Switch.

2.You will enter to User EXEC Mode after Telnet connection is successfully created, but for switch security concerns, you are required to set a password which functions to further access to Privileged EXEC Mode when you configure the login mode.

Login Local Mode

Firstly, configure the Telnet login mode as “login local” and set the password for entering into the Privileged EXEC Mode as 123 in the prompted DOS screen shown in Figure 1-6.

Figure 1-6 Configure login local mode

Now, you can logon by Telnet in login local mode.

1.Make sure the switch and the PC are in the same LAN. Click Start → Run to open the Run window, and type cmd in the prompt Run window as Figure 1-7 and click OK.

Figure 1-7 Run Window

2.Open Telnet, then type telnet 192.168.0.1 in the command prompt shown as Figure 1-8, and press the Enter button.

Figure 1-8 Connecting to the Switch

3.Type the default user name and password admin/admin, then press the Enter button so as to enter User EXEC Mode.

Figure 1-9 Enter into the User EXEC Mode

Now you can manage your switch with CLI commands through Telnet connection.

4.Type enable command to enter Privileged EXEC Mode. A password that you have set through Console port connection is required. Here the password is set as 123.

8

Figure 1-10 Enter into the Privileged EXEC Mode

Login Mode

Firstly configure the Telnet login mode as “login”, and both the connection password and the Privileged EXEC Mode password as 123 in the prompted DOS screen shown in Figure 1-11.

Figure 1-11 Configure login mode

Now, you can logon by Telnet in login mode:

1.Open Telnet, then type telnet 192.168.0.1 in the command prompt shown as Figure 1-12, and press the Enter button.

9

Figure 1-12 Connecting to the Switch

2.You are prompted to enter the connection password 123 you have set through Console port connection, and then you are in User EXEC Mode.

Figure 1-13 Enter into the User EXEC Mode

3.When entering enable command to access Privileged EXEC Mode, you are required to give the password 123 you have set through Console port connection.

Figure 1-14 Enter into the Privileged EXEC Mode

10

Now you can manage your switch with CLI commands through Telnet connection.

Note:

You can refer to Chapter 10 User Manage Commands for detailed commands information of the Telnet connection configuration.

1.2CLI 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 gigabitEthernet, Interface link-aggregation and some other modes, which is shown as the following diagram.

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 console port or 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 gigabitEthernet: Configure parameters for an Ethernet port, such as Duplex-mode, flow control status.

b). Interface range gigabitEthernet: The commands contained are the same as that of the Interface Ethernet. 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: Displays all information of switch, for example: statistic information, port information, VLAN information.

history: Displays the commands history.

12

1.3Security 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 connecting console port with the switch or 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.

1.4Conventions

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: switchport type { access | trunk | general }

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.

13

1.4.3 Parameter Format

Some parameters must be entered in special formats which are shown as follows:

MAC Address must be entered 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, 3-5,7 indicates choosing 1,3,4,5,7.

The port number should format as 1/0/3, meaning unit/slot/port. The unit number is always 1, and slot number is always 0 and the port number is a variable (an actual value must be assigned).
