4.2 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.

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.

Chapter 6 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 6-1 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.
29
Easy Smart Configuration Utility
User Guide
(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 6-2 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.

6.4 802.1Q 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 packet.
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.

Chapter 7 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 four different priority queues and
then forwards the packets according to WRR scheduling algorithms to implement QoS function.
Figure 7-1 QoS Function
Traffic classification: Identifies packets conforming to certain characters according to certain
rules.
Map: This switch supports four priority queues. The priority queues are labeled as 1(Lowest),
2(Normal), 3(Medium) and 4(Highest), among them the bigger the value, the higher the
priority. The ingress packets are mapped to four different priority queues based on the QoS
modes. This switch implements three priority modes based on port, on 802.1P and on DSCP.
Queue scheduling algorithm: When the network is congested, the problem that many packets
compete for resources must be solved, usually in the way of queue scheduling. In all QoS
modes, this switch adopts WRR scheduling algorithm. In WRR scheduling algorithm, 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.
QoS Mode
This switch implements three priority modes based on port, on 802.1P and on DSCP. By default, the
priority mode based on port is enabled and the other two modes are optional.
36
Easy Smart Configuration Utility
User Guide
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 7-2 802.1Q 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:
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,
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.
3. DSCP based
Figure 7-3 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
37
Easy Smart Configuration Utility
User Guide
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.
7.1 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, on 802.1P or on DSCP. The port-based
QoS mode supports four priority queues. The port priority queues are labeled as 1, 2, 3, and 4.
