Chapter 5 Switching Switching module is used to configure the basic functions of the switch, including three submenus: Port Setting, IGMP Snooping and Port Trunk.
5.1 Port Setting
On this page, you can configure and view the basic parameters of each port, including the port status, speed, duplex mode and flow control. As the parameters will affect the working mode of the port, please set the parameters appropriate to your needs.
Choose the menu SwitchingPort Setting to load the following page.
Figure 5-1 Port Setting
The following entries are displayed on this screen:
Port Setting
Port: Select the desired port for configuration. It is multi-optional.
16
Status: Allows you to enable or disable the port. Enable" indicates that the port is operational and "Disable" indicates the port is non-operational. If a port is unused for a long time, its status can be set to Disable to cut down the energy cost.
Speed/Duplex: Select the Speed and Duplex mode for the port. The device connected to the switch should be in the same Speed and Duplex mode with the switch. Available field values are Auto, 10M HD, 10M FD, 100M HD, 100M FD and 1000M FD. "HD" stands for Half-Duplex and "FD" stands for Full-Duplex. "Auto" means auto negotiation.
Flow Control: Allows you to On/Off the Flow Control feature. When On is selected, the switch can synchronize the speed with its peer to avoid the packet loss caused by congestion.
Note:
The switch cannot be managed through the disabled port. Please enable the port which is used to manage the switch.
5.2 IGMP Snooping
Internet Group Management Protocol (IGMP) snooping is a multicast control mechanism, which can be used on the switch for dynamic registration of the multicast group.
IGMP Snooping allows the switch to recognize the IGMP messages transmitted between network stations or devices and an IGMP host. When receiving IGMP report message from the IGMP host, the switch will add the port to the multicast address table; when listening to IGMP leave message from the IGMP host, the switch will remove the port from the multicast address table. By managing and controlling the multicast address table, the broadcasting of multicast traffic can be effectively prevented in the network.
On this page you can enable IGMP Snooping feature, Report Message Suppression feature and view the current IGMP Group information.
Choose the menu SwitchingIGMP Snooping to load the following page.
Figure 5-2 IGMP Snooping
17
The following entries are displayed on this screen:
IGMP Snooping
IGMP Snooping: Enable or disable IGMP snooping function globally on the switch.
Report Message Suppression
Enable or disable Report Message Suppression function globally. If this function is enabled, the first Report Message from the listener will forward to the router ports while the subsequent Report Message will be suppressed to reduce the IGMP packets.
IP Address: Displays the multicast IP address.
VLAN ID: Displays the VLAN ID of the multicast group. If the packet does not carry VLAN ID, then here displays the PVID of the port. All port members of a multicast group should be divided to the same VLAN, and have the same PVID.
Ports: Displays the forwarding port list of the multicast group.
5.3 Port Trunk
Port trunk is used to combine a number of ports together to make a single high-bandwidth data
path, which can highly extend the bandwidth. The bandwidth of the trunk is the sum of bandwidth
of its member ports.
There are some rules on using trunk:
For the member ports in a trunk group, their configuration of Port setting (Speed and Duplex,
Flow Control), QoS must be the same.
For the newly joined member ports in a trunk group, their default setting of Port setting
(Speed and Duplex, Flow Control), QoS will be configured the same as that of the first
member port in the trunk group.
The trunk member ports cannot be set as mirroring port.
Before setting the trunk, its member ports should be divided to the same VLAN, and have the
same PVID and drop the untagged packet rule. Change of the trunk setting will not affect the
VLAN setting.
If the port trunk is needed, you are suggested to configure the port trunk function here before
configuring the other functions for the member ports.
On this page, you can configure and view the information of the trunk group of the switch.
18
Choose the menu SwitchingPort Trunk to load the following page.

Here you can configure and view the port parameters.
Trunk Group Setting
Group ID: Select an identified number for the trunk group from the drop-down list.
Port: Select the port as the trunk group member. It is multi-optional. Clearing all the ports of the trunk group will delete this trunk group.
Tips:
Calculate the bandwidth for a trunk group: If a trunk consists of the four ports whose Speed/Duplex mode is 1000Mbps/Full Duplex, the whole bandwidth of the trunk group is up to 8000Mbps (2000Mbps * 4) because the bandwidth of each member port is 2000Mbps counting the up-linked speed of 1000Mbps and the down-linked speed of 1000Mbps.

Chapter 6 Monitoring Monitoring module monitors the traffic information of the switch, and provides the convenient method to locate and solve the network problem, includes four submenus: Port Statistics, Port Mirror, Cable Test and Loop Prevention.
6.1 Port Statistics
On this page you can view the statistic information of each port, which facilitates you to monitor the traffic and locate faults promptly.
Choose the menu MonitoringPort Statistics to load the following page.
Figure 6-1 Port Statistics Info
The following entries are displayed on this screen:
Port Statistics Info
Port: Displays the port number of the switch.
Status: Displays whether the port is enabled or disabled.
Link Status: Displays whether the port is link up or link down.
TxGoodPkt: Displays the number of good packets transmitted on the port. The error packets are not counted in.
TxBadPkt: Displays the number of error packets transmitted on the port.
RxGoodPkt: Displays the number of good packets received on the port. The error packets are not counted in.
20
RxBadPkt: Displays the number of error packets received on the port.
6.2 Port Mirror
Port mirror functions to monitor and mirror network traffic by forwarding copies of incoming and outgoing packets from one/multiple ports (mirrored port) to a specific port (mirroring port). Usually, the mirroring port is connected to a data diagnosis device, which is used to analyze the mirrored packets for monitoring and troubleshooting the network.
Choose the menu MonitoringPort Mirror to load the following page.

The following entries are displayed on this screen:
Port Mirror
Port Mirror: Allows you to enable or disable the port mirror feature of the specified port.
Mirroring Port: Select a port from the pull-down list as the mirroring port.
Mirrored Port
Mirrored Port: Select a port from the pull-down list as the mirrored port to monitor the traffic. Trunk member cannot be defined here. It is multi-optional.
Ingress: Select whether to monitor the ingress traffic. When the ingress is enabled, the ingress traffic received by the mirrored port will be copied to the mirroring port.
Egress: Select whether to monitor the egress traffic. When the egress is enabled, the outgoing packets sent by the mirrored port will be copied to the mirroring port.
Note:
1. The trunk member cannot be selected as the mirroring port.
2. A port cannot be set as the mirrored port and the mirroring port simultaneously.
3. The port mirror function can take effect span the multiple VLANs.
6.3 Cable Test
This switch provides cable test to diagnose the connection status of the cable connected to the switch and the distance to the problem location, which facilitates you to locate and diagnose the trouble spot of the network.
Choose the menu MonitoringCable Test to load the following page.

Chapter 7 VLAN The traditional Ethernet is a data network communication technology based on CSMA/CD (Carrier Sense Multiple Access/Collision Detect) via shared communication medium. Through the traditional Ethernet, the overfull hosts in LAN will result in serious collision, flooding broadcasts, poor performance or even breakdown of the Internet. Though connecting the LANs through switches can avoid the serious collision, the flooding broadcasts cannot be prevented, which will occupy plenty of bandwidth resources, causing potential serious security problems.
A Virtual Local Area Network (VLAN) is a network topology configured according to a logical scheme rather than the physical layout. The VLAN technology is developed for switches to control broadcast in LANs. By creating VLANs in a physical LAN, you can divide the LAN into multiple logical LANs, each of which has a broadcast domain of its own. Hosts in the same VLAN communicate with one another as if they are in a LAN. However, hosts in different VLANs cannot communicate with one another directly. Therefore, broadcast packets are limited in a VLAN. Hosts in the same VLAN communicate with one another via Ethernet whereas hosts in different VLANs communicate with one another through the Internet devices such as router, the Lay3 switch, etc. The following figure illustrates a VLAN implementation.
Figure 7-1 VLAN implementation
Compared with the traditional Ethernet, VLAN enjoys the following advantages.
1 Broadcasts are confined to VLANs. This decreases bandwidth utilization and improves network performance.
2 Network security is improved. VLANs cannot communicate with one another directly. That is, a host in a VLAN cannot access resources in another VLAN directly, unless routers or Layer 3 switches are used.
3 Network configuration workload for the host is reduced. VLAN can be used to group specific hosts. When the physical position of a host changes within the range of the VLAN, you do not need to change its network configuration.
25
There are 3 types of VLAN modes supported in the switch:
1. MTU VLAN
MTU VLAN (Multi-Tenant Unit VLAN) defines an uplink port which will build up several VLANs with each of the other ports. Each VLAN contains two ports, the uplink port and one of the other ports in the switch, so the uplink port can communicate with any other port but other ports cannot communicate with each other.
2. Port Based VLAN
VLANs are divided based on ports. By
