Note:
Please make sure that there is only one uplink pipeline between switch

and switch, or between switch and hub, otherwise multi pipeline will
form loops, this may cause the whole network to broke down. (Port
Trunking is an exception)
Chapter Three Configuration Guide
3.1 Fast Login
Notice: You must set IP Address manually for the management PC,
because there is not built-in DHCP server in
TEH1208/TEH1216/TEH1224. You can login and configure the switch
after setting the IP Address. The default parameters of the switch are as
follows:
Parameter Default Value
Default IPAddress 192.168.0.1
Default User’s Name admin
Default Password admin
Figure 1
You can fast log in to the configuration Interface of the switch through
the following steps:
a. Connect the switch to NIC port of the computer
b. Turn on the power of the switch
c. Make sure that the IP Address of the computer is at 192.168.0.x (where
x is a number between 2 and 254)

d. Open the Web browser, enter IP Address http://192.168.0.1 into the
address location
e. Input user name and password in the dialog page (default user name
and password are “admin”), press “Enter” button and you will login to the
configuration Interface of the switch as the Figure as follows:
Figure 2
On the menu which is on the left hand side of the page, there are totally 8
items: “Administrator”, “Port Management”, “VLAN Setting”, “Trunk Setting”, “QoS
Setting”, “MAC Address Configuration”.,” Configuration Backup/Recovery” and “Logout”.
Single click on a certain button and you will have the related function
configured. We will give detailed introduction to the setting step by step
in the following chapters.

3.2.4 Load Default Setting

Figure 6
Load: Click “Load” and restore to default setting, this function is similar
to the function of the “Reset” button.
3.2.5 Firmware Update
Figure 7
Update: Click “Update” and start to update the software of

switch
You must install DHCP+TFTP server software on your
computer before software updating, it is strongly recommended
that you should use haneWIN DHCP Server Ver2.1 or higher
version. After the configuration of DHCP server, click “Update”
button, updating of software takes around 2 minutes; switch will
restart after software updating, and you should re-log in.
Note: You could also visit our website www.tenda.cn to
obtain the updating data packet and the detailed operating guide
for updating. Please be careful in updating, it is suggest that you
should disconnect the network connectivity except the
connectivity with the computer for updating, and please avoid
power off in accident or computer broke down of the updating
computer.
3.3 Port Management
3.3.1 Port Configuration
In port management you can set: port Auto-Negotiation, speed, duplex,
and flow control mode respectively for each port. So you can choose the
port to work at status of: 10Mbps half duplex, 10Mbps full duplex,
100Mbps half duplex, 100Mbps full duplex and Auto-Negotiation, totally
5 modes. (Notice: Default mode is Auto-Negotiation Mode). When the

switch is started, each port of the switch will automatically negotiate with
the connected devices and it will choose an optimal mode to maximize
performance of all devices. For non-Auto-Negotiation modes, it should
be matched and adjusted to status of other devices, or the others devices
should be at status of Auto-negotiation, otherwise, failure of
communication will occur. Flow control means that two connected
devices will control data flow and avoid packet loss. 802.3x mode is
suitable for full-duplex mode. Backpressure is suitable for half-duplex
mode. If two modes are all started, switch will choose flow control mode
automatically according to duplex modes.
Configuration of port management will affect port bandwidth control,
port mirroring and Trunking.
Figure 8
Port Configuration
¾Port: Select the port which you are going to set.

¾Auto-Negotiation: Enable or disable port Auto-Negotiation
¾Rate: Set the port working at 10Mbps or 1000Mbps
¾Duplex Setting: To set the ports working at full/half duplex modes.
¾Back pressure control: To enable or disable back pressure control,
suitable for half duplex mode.
¾Flow Control: Support IEEE802.3x full duplex flow control, half
duplex backpressure flow control
Port Status
To display the current and actual working mode and configuration of each
port
3.3.2 Port Mirroring
¾The port mirroring function enables you to transfer packet from
monitored port to monitoring port (received packet, sent packet or
sent and received packet mode set by the monitoring mode). Meet the
network monitoring demand of security department in net café,
enterprise.
¾If the monitoring port and the monitored port are set to be the same
port, the monitored port will be ignored automatically by the system.
¾Bandwidth of monitoring port should be the same or wider than the
monitored port
¾Support monitoring among different VLANs

Figure 9
Port Mirroring:
¾Monitoring Mode: Set monitoring mode aimed at packet
¾Monitoring Port: Select a monitoring port
¾Monitored Port: Select one or more monitored ports
3.3.3 Bandwidth Control
¾Port Bandwidth Control: port bandwidth control enables you to
control the transmission rate of each port, including upstream and
downstream, and stop the user of a certain port from using too much
bandwidth. And user of other ports will have more stable bandwidth.
This function can be used in net café or broadband connection to
smart residential area.
¾If the rate set is higher than the actual connectivity rate of the port, the
value displayed is the value that you set, but not the value of the

actual value.
Figure 10
¾Port: Select the port that you are going to control
¾Transmission Rate: Set the transmission rate of the port
¾Receiving Rate: Set the receiving rate of the port
¾Restore to Default Setting: Click and restore to default setting
Bandwidth Control Status
Display the Transmission Rate, Receiving Rate and Connecting Rate of
each port (10Mbps or 100Mbps)
3.3.4 Broadcast Storm Control
Broadcast Storm Max Value refers to the Broadcast Storm Limited Value,
for example, if Broadcast storm packets received at 100Mbps in 10ms
reach 127 (or the pre-set Max Value), switch will detect that Broadcast

Storm is happening. And it will start the Broadcast Storm Control
function and give up the unnecessary broadcast storm packets.
Figure 11
¾Control Function Selecting: Choose to Start control function
¾Broadcast Storm Max Value: the Max Broadcast Storm Value that you
can set (From 1~127)
3.4 VLAN Setting
3.4.1 Group VLAN Setting
TEH1208/TEH1216/TEH1224 supports Port-Based VLAN, only the port
set in the same VLAN group are able to communication with each other,
and VALN group description is supported. Under default setting, VLAN
group 1 contains all the 8/16/24 ports, so all ports of the switch are able to
communicate with each other; One port can belong to one or more VLAN
groups, and is able to communicate with ports from different VLAN
groups at the same time.

Figure 12
¾VLAN Group: You can set VLAN group number. System is default to
support 24 groups.
¾VLAN Group Members: Select the port and add to the selected
VLAN group
¾VLAN Group Description: Give brief description to your VLAN
group (in 16 characters)
¾Restore to Factory Default Setting: Click and restore to original
function of VLAN group
VLAN Group Status
Display the members of your set VLAN groups and the VLAN
descriptions. (VLAN groups, VLAN group description, VLAN group
status)
