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
through an Ethernet port. To log on to the switch by a Telnet connection, please take the following
steps:
1. Make sure the switch and the PC are in the same LAN.
2. Click Start → Run to open the Run window.
Figure 1-1 Open the Run window
3. Type cmd in the prompt Run window as Figure 1-2 and click OK.
Figure 1-2 Run Window

4. Type telnet 192.168.0.1 in the command prompt shown as Figure 1-3, and press the Enter
button.
Figure 1-3 Connecting to the Switch
5. Type the User name and Password (the factory default value for both of them is admin) and
press the Enter button, then you can use the CLI now, which is shown as Figure1-4.
Figure 1-4 Log in 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
gigabitEthernet, Interface link-aggregation and some other modes, which is shown as the following
diagram.

Enter the exit command or the
# command to return to Global
configuration 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.
6
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.
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
7
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, 1,3-5,7 indicates choosing 1,3,4,5,7.

Chapter 3 IEEE 802.1Q VLAN Commands
VLAN (Virtual Local Area Network) technology is developed for the switch to divide the LAN into
multiple logical LANs flexibly. Hosts in the same VLAN can communicate with each other,
regardless of their physical locations. VLAN can enhance performance by conserving bandwidth,
and improve security by limiting traffic to specific domains.

Parameter
sp —— Strict-Priority Mode. In this mode, the queue with higher priority will
occupy the whole bandwidth. Packets in the queue with lower priority are sent
only when the queue with higher priority is empty.
wrr —— Weight Round Robin Mode. In this mode, packets in all the queues
are sent in order based on the weight value for each queue. The weight value
ratio of TC0, TC1, TC2 and TC3 is 1:2:4:8.
sp+wrr —— Strict-Priority + Weight Round Robin Mode. In this mode, the
switch provides two scheduling groups, SP group and WRR group. Queues in
SP group and WRR group are scheduled strictly based on Strict-Priority mode
while the queues inside WRR group follow the WRR mode. In SP + WRR mode,
TC3 is the SP group; TC0, TC1 and TC2 belong to the WRR group and the
weight value ratio of TC0, TC1 and TC2 is 1:2:4. In this way, when scheduling
queues, the switch allows TC3 to occupy the whole bandwidth following the SP
mode and the TC0, TC1 and TC2 in the WRR group will take up the bandwidth
according to their ratio 1:2:4.
