Choose the menu Switching→Port 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.
  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.

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 Switching→IGMP Snooping to load the following page.
Figure 5-2 IGMP Snooping

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.

LAG

LAG 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 LAG is the sum of bandwidth of its member ports.
There are some rules on using LAG:

• For the member ports in a LAG group, their configuration ofPort setting (Speed and Duplex, Flow Control), QoS must be the same.
• For the newly joined member ports in a LAG group, their default setting ofPort setting (Speed and Duplex, Flow Control), QoS will be configured the same as that of the first member port in the LAG group.
• The LAG member ports cannot be set as mirroring port.
• Before setting the LAG, its member ports should be divided to the same VLAN, and have the same PVID and drop the untagged packet rule. Change of the LAG setting will not affect the VLAN setting.

If the LAG is needed, you are suggested to configure the LAG function here before configuring the other functions for the member ports.
On this page, you can configure and view the information of the LAG group of the switch.
Choose the menu Switching→LAG to load the following page.
Figure 5-3 LAG Setting

Here you can configure and view the port parameters.

• LAG 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 LAG group: If a LAG consists of the four ports whose Speed/Duplex mode is 1000Mbps/Full Duplex, the whole bandwidth of the LAG 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.

Monitoring

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. (1) Broadcasts are confined to VLANs. This decreases bandwidth utilization and improves network performance.
2. (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. (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.

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 default, the Port Based VLAN is enabled.
3. 802.1Q VLAN
   The IEEE 802.1Q protocol defines a new format of the frame; it adds a Tag header in the original Ethernet frame, as follows:
   Figure 7-2 IEEE 802.1Q frame
   

VLAN tags in the packets are necessary for the switch to identify packets of different VLANs. The switch works at the data link layer in OSI model and it can identify the data link layer encapsulation of the packet only, so you can add the VLAN tag field into the data link layer encapsulation for identification.
IEEE 802.1Q Tag VLAN is divided by VLAN ID (VID). On receiving a frame, the switch checks the VID in the Tag header of the frame to decide which VLAN it belongs to. If the receiving frame doesn't contain the Tag header, the switch will assign a Tag to the frame, using the PVID of the port as its VID.
In this User Guide, the tagged packet refers to the packet with VLAN tag whereas the untagged packet refers to the packet without VLAN tag.
The VLAN module is mainly for VLAN configuration, including four submenus: MTU VLAN, Port Based VLAN, 802.1Q VLAN and 802.1Q PVID Setting.

MTU VLAN

On this page you can choose to enable MTU VLAN mode and configure VLANs.
Choose the menu VLAN→MTU VLAN to load the following page.
Figure 7-3 MTU VLAN Configuration

Note:

1. The uplink port will form 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, thus the uplink port can communicate with any other port but other ports cannot communicate with each other.
2. For the first time the MTU VLAN mode is enabled, the switch will set port 1 as the uplink port by default.

Port Based VLAN

On this page you can configure Port Based VLAN feature and view the related settings.
Choose the menu VLAN→Port Based VLAN to load the following page.
Figure 7-4 Port Based VLAN Configuration

To ensure the normal communication of the factory switch, the default VLAN of all ports is set to VLAN1. VLAN 1 cannot be deleted.
The following entries are displayed on this screen:

• Port Based VLAN Configuration

  Tagged:	Click the check box to configure the egress rule of the traffic on this port as tagged. The switch adds the tag header before sending the packet.
  Not Member:	Click the check box to exclude the port from the current VLAN.

802.1Q PVID Setting

PVID (Port Vlan ID) is the default VID of the port. When the switch receives an un-VLAN-tagged packet, it will add a VLAN tag to the packet according to the PVID of its received port and forward the packets.
When creating VLANs, the PVID of each port, indicating the default VLAN to which the port belongs, is an important parameter with the following two purposes:

1. When the switch receives an un-VLAN-tagged packet, it will add a VLAN tag to the packet according to the PVID of its received port
2. PVID determines the default broadcast domain of the port, i.e. when the port receives UL packets or broadcast packets, the port will broadcast the packets in its default VLAN.

On this page you can configure PVID of the specified port. By default, the PVID of all ports is 1. Choose the menuVLAN→802.1Q PVID Setting to load the following page.
Figure 7-6 802.1Q VLAN PVID Setting

The following entries are displayed on this screen:

• 802.1Q VLAN PVID Setting

  Select:	Select the desired port for configuration. It is multi-optional.
  Port:	Displays the port number.
  PVID:	Enter a PVID number for the port. When adding the tag header to the received untagged packet, the switch will automatically uses this PVID value as the VLAN ID of the added tag.

Note: 802.1Q VLAN should be enabled before setting PVID.

QoS

QoS (Quality of Service) functions to provide different quality of service for various network applications and requirements and optimize the bandwidth resource distribution so as to provide a network service experience of a better quality.

• QoS
  This switch classifies the ingress packets, maps the packets to different priority queues and then forwards the packets according to weighted round robin (WRR) scheduling algorithm to implement QoS function.
  Figure 8-1 QoS function
  
  • Traffic classification: Identifies packets conforming to certain characters according to certain rules.
  • Map: The user can map the ingress packets to different priority queues based on the priority modes. This switch implements three QoS modes based on port /802.1P /DSCP.
  • WRR-Mode: Weight Round Robin Mode. In this mode, packets in all the queues are sent in order based on the weight value for each queue and every queue can be assured of a certain service time. The weight value indicates the occupied proportion of the resource. In WRR mode, though the queues are scheduled in order, the service time for each queue is not fixed, that is to say, if a queue is empty, the next queue will be scheduled. In this way, the bandwidth resources are made full use of. The default weight value ratio of TC1, TC2, TC3 and TC4 is 1:2:4:8.
• QoS Mode
  This switch implements three QoS modes based on port /802.1P /DSCP. By default, the QoS mode based on port is enabled and the others are optional.

1. Port Based
   When port-base QoS mode is enabled, the user can manually map the ingress packets of the port to four different priority queues. After that, the switch will preferentially send packets in the queue with higher priority, and only when the queue with higher priority is empty, packets in the queue with lower priority are sent.
2. 802.1P Based
   Figure 8-2 802.1Q frame
   
   As shown in the figure above, each 802.1Q Tag has a Pri field, comprising 3 bits. The 3-bit priority field is 802.1p priority in the range of 0 to 7. The 802.1p priority value determines how the switch maps the ingress packets to the priority queues. The mapping relationship between eight 802.1p priority value and priority queues is shown as follows:
   Figure 8-3 Map 802.1P priority
   

• Priority 1 and 2 are assigned to the 1 (Lowest) priority queue.
• Priority 0 and 3 are assigned to the 2 (Normal) priority queue.
• Priority 4 and 5 are assigned to the 3 (Medium) priority queue.
• Priority 6 and 7 are assigned to the 4 (Highest) priority queue.
  When 802.1P QoS mode is enabled, the switch will automatically map the ingress packets to priority queues based on the 802.1p priority and the above mapping relationship. After that, the switch will preferentially send packets in the queue with higher priority, and only when the queue with higher priority is empty, packets in the queue with lower priority are sent. As for the untagged packets, the switch will forward it according to the default port-based QoS mode.

3. DSCP based
   Figure 8-4 IP datagram
   

As shown in the figure above, the ToS (Type of Service) in an IP header contains 8 bits. The first three bits indicate IP precedence in the range of 0 to 7. RFC2474 re-defines the ToS field in the IP packet header, which is called the DS field. The first six bits (bit 0-bit 5) of the DS field indicate DSCP priority in the range of 0 to 63. The last 2 bits (bit 6 and bit 7) are reserved. The mapping relationship between sixty-four DSCP priority value and priority queues is shown as follows:

• Priority 0 to 15 are assigned to the 1 (Lowest) priority queue.
• Priority 16 to 31 are assigned to the 2 (Normal) priority queue.
• Priority 32 to 47 are assigned to the 3 (Medium) priority queue.
• Priority 48 to 63 are assigned to the 4 (Highest) priority queue.

When DSCP QoS mode is enabled, the switch will automatically map the ingress packets to priority queues based on the DSCP precedence and the above mapping relationship. After that, packets in all the queues are sent in order based on the weight value for each queue. The switch implements four scheduling queues, TC1, TC2, TC3 and TC4. TC1 has the lowest priority while TC4 has the highest priority. The weight value ratio of TC1, TC2, TC3 and TC4 is 1:2:4:8.
As for the untagged packets, the switch will forward it according to the default priority mode.
The QoS module is mainly for priority configuration and traffic control, including three submenus: QoS Basic, Bandwidth Control and Storm Control.

QoS Basic

This switch classifies the ingress packets, maps the packets to different priority queues and then forwards the packets to implement QoS function.
This switch implements three priority modes based on port /802.1P /DSCP. The port-based QoS mode supports four priority queues. The port priority queues are labeled as 1, 2, 3, and 4.
On this page you can configure and view QoS mode and the port-based priority setting.
Choose the menu QoS→QoS Basic to load the following page.
Figure 8-5 QoS Basic

The following entries are displayed on this screen:

• Global Config

  QoS Mode:

  Select the desired QoS mode. Port Based: The switch classifies the ingress packets and maps the packets to different priority queues based on which port the packets come from. 802.1p Based: The switch classifies the ingress packets and maps the packets to different priority queues based on the 802.1p priority field in the 802.1Q tag. DSCP Based: The switch classifies the ingress packets and maps the packets to different priority queues based on the DSCP priority field in the IP ToS field.

• Port-based Priority Setting

  Port:	Select the desired port to configure its priority queue. It is multi-optional.
  Priority Queue:	Specify the priority queue the packets from the port are mapped to. The priorities are labeled as 1~4 and among them the bigger the value, the higher the priority.

Bandwidth Control

Bandwidth control functions to control the ingress/egress traffic rate on each port via configuring the available bandwidth of each port. In this way, the network bandwidth can be reasonably distributed and utilized.
On this page you can configure and view the bandwidth control function information.
Choose the menu QoS→Bandwidth Control to load the following page.
Figure 8-6 Bandwidth Control Setting

The following entries are displayed on this screen:

• Bandwidth Control Setting

  Port:	Select the desired port for bandwidth control configuration. It is multi-optional.
  Ingress Rate(Kbps):	Here you can configure the port ingress rate limit. If the rate for receiving packets on the port exceeds the set rate, the packets will be discarded.
  Egress Rate(Kbps):	Here you can configure the port egress rate limit. If the rate for sending packets on the port exceeds the set rate, the packets will be discarded.

Note:

1. A port cannot enable both Storm Control and Ingress Rate Control at the same time.
2. When egress bandwidth control feature is enabled for one or more ports, you are suggested to disable the flow control on each port to ensure the switch works normally.

Storm Control

Storm control function allows the switch to filter broadcast, multicast and UL frame in the network. If the transmission rate of the chosen packets exceeds the set bandwidth, the packets will be automatically discarded to avoid network broadcast storm.
On this page you can configure and view the storm control function information.
Choose the menu QoS→Storm Control to load the following page.
Figure 8-7 Storm Control Setting

The following entries are displayed on this screen:

• Storm Control Setting

  Port:	Select the desired port for storm control configuration. It is multi-optional.
  Status:	Allows you to enable or disable the storm control function.
  Total Rate(Kbit/sec):	Select the rate for receiving packets on the port. The packet traffic exceeding the rate will be discarded. It ranges from 0 to 100000, and must be integral multiple of 64.
  Included Storm Type:	Select to filter broadcast/multicast/UL frame in the network, if the transmission rate of the chosen packets exceeds the set rate, the packets will be automatically discarded to avoid network broadcast storm. It is multi-optional. UL-Frame: If UL-Frame packets traffic exceeds the rate on the port, they will be discarded. Multicast: If multicast packets traffic exceeds the rate on the port, they will be discarded. Broadcast: If broadcast packets traffic exceeds the rate on the port, they will be discarded.

Note: If you enable storm control feature for the ingress rate control-enabled port, the ingress rate control feature will be disabled for this port.
