port join into aggregation group. ST3208 has max 4 groups, and one aggregation group can
support max 8 member ports.
4.3.2 VLAN
Figure 4-3-2
19
Introduction to VLAN
The traditional Ethernet is a broadcast network, where all hosts are in the same broadcast
domain and connected with each other through hubs or switches. Hubs and switches, which are
the basic network connection devices, have limited forwarding functions.
A hub is a physical layer device without the switching function, so it forwards the received
packet to all ports except the inbound port of the packet.
A switch is a link layer device which can forward a packet according to the MAC address of
the packet. A switch builds a table of MAC addresses mapped to associated ports with that
address and only sends a known MAC’s traffic to one port. When the switch receives a
broadcast packet or an unknown unicast packet whose MAC address is not included in the
MAC address table of the switch, it will forward the packet to all the ports except the
inbound port of the packet. The above scenarios could result in the following network
problems.
Large quantity of broadcast packets or unknown unicast packets may exist in a network,
wasting network resources.
A host in the network receives a lot of packets whose destination is not the host itself,
causing potential serious security problems.
Related to the point above, someone on a network can monitor broadcast packets and
unicast packets and learn of other activities on the network. Then they can attempt to
access other resources on the network, whether or not they are authorized to do this.
Isolating broadcast domains is the solution for the above problems. The traditional way is to use
routers, which forward packets according to the destination IP address and does not forward
broadcast packets in the link layer. However, routers are expensive and provide few ports, so
they cannot split the network efficiently. Therefore, using routers to isolate broadcast domains
has many limitations.
The Virtual Local Area Network (VLAN) technology is developed for switches to control
broadcasts in LANs.
A VLAN can span multiple physical spaces. This enables hosts in a VLAN to be located in different
physical locations. 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 in the traditional Ethernet way. However, hosts in different VLANs cannot
communicate with each other directly but need the help of network layer devices, such as
routers and Layer 3 switches.
Advantages of VLANs
Compared with traditional Ethernet technology, VLAN technology delivers the following benefits:
Confining broadcast traffic within individual VLANs. This saves bandwidth and improves
network performance.
20
Improving LAN security. By assigning user groups to different VLANs, you can isolate them at
Layer 2. To enable communication between VLANs, routers or Layer 3 switches are
required.
Flexible virtual workgroup creation. As users from the same workgroup can be assigned to
the same VLAN regardless of their physical locations, network construction and
maintenance is much easier and more flexible.

4.3.3 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.
23
Figure 4-3-7
QoS
This switch classifies the ingress packets, maps the packets to different priority queues and then
forwards the packets according to specified scheduling algorithms to implement 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 priority modes based on port.
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. The switch
supports four schedule modes: SP.
Priority 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.
Port Priority
Port priority is a priority level of the port. After port priority is configured, the data stream will be
mapped to the egress queues directly according to the priority level of the port.
24
Schedule Mode
When the network is congested, the problem that many packets compete for resources must be
solved, usually in the way of queue scheduling. The switch implements four scheduling queues.
SP-Mode: 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. The switch has four egress queues labeled. The disadvantage of SP queue is
that: if there are packets in the queues with higher priority for a long time in congestion, the
packets in the queues with lower priority will be “starved to death” because they are not served.
4.3.3.1 QoS Configure
Port Priority
On this page you can configure the port priority.
Choose the menu Configuration →QoS →Port-based Priority to load the following page.
Figure 4-3-8
1. Displays the physical port number of the switch.

25
4.3.4 Loop Prevention
Figure 4-3-9
With loop prevention feature enabled, the switch can prevention loops using loop-prevention
packets. When a loop is detected, the switch will display an alert or further block the
corresponding port according to the port configuration.
Choose the menu Configuration →Loop Prevention → Loop Prevention to load the following
page.
Figure 4-3-10
26
4.3.5 Port-based Mirroring
Port mirroring allows you to duplicate the packets passing specified ports to the destination
mirroring port. As destination mirroring ports usually have data monitoring devices connected to
them, you can analyze the packets duplicated to the destination mirroring port on these devices
so as to monitor and troubleshoot the network.
Figure 4-3-11
Choose the menu Configuration→ Port-based Mirroring to load the following page.
Select the Source Port from where you want to copy frames and the Target Port, which receives
the copies from the source port.
1. Change the Port-base Mirroring Status menu to On.
2. Click Apply to let the changes take effect.
3. Select the Source Direction, Ingress, Egress.
4.3.6 Port Isolation
To implement isolation, you can add different ports to different VLANs. However, this will waste
the limited VLAN resource. With port isolation, the ports can be isolated within the same VLAN.
Thus, you need only to add the ports to the isolation group to implement isolation. This provides
27
you with more secure and flexible networking schemes.
Choose the menu Configuration→ Port Isolation to load the following page.
Figure 4-3-12
On the current device:
Currently, only one isolation group is supported on a device, which is created automatically
by the system as isolation group. The user cannot remove the isolation group or create
other isolation groups.
The number of the ports an isolation group can contain is not limited.
4.3.7 Bandwidth Control
Rate limit 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.
Choose the menu Configuration→ Bandwidth Control to load the following page.
28
Figure 4-3-13
If you select port to set ingress/egress rate, the system will automatically select integral multiple
of 16Kbps that closest to the rate you entered as the real ingress/egress rate.
Ingress: Configure the bandwidth for receiving packets on the port. You can select a port to set
Ingress rate, the system will automatically select integral multiple of 16Kbps that closest to the
rate you entered as the real Ingress rate.
Egress: Configure the bandwidth for sending packets on the port. You can select a port to set
Egress rate, the system will automatically select integral multiple of 16Kbps that closest to the
rate you entered as the real Egress rate.
4.3.8 Jumbo Frame
Due to tremendous amount of traffic occurring in Ethernet, it is likely that some frames might
have a frame size greater than the standard Ethernet frame size. By allowing such frames (called
jumbo frames) to pass through Ethernet ports, you can forward frames with a size greater than
the standard Ethernet frame size and yet still within the specified parameter range.
Choose the menu Configuration→ Jumbo Frame to load the following page.
29
Figure 4-3-14
You can set the length of jumbo frames that can pass through all the Ethernet ports.
By default, the device allows jumbo frames with the length of 1522/1536/1552/2048 bytes to
pass through all Ethernet ports.
4.3.9 MAC Constraint
MAC address learning capability, you can setting of maximum number of MAC addresses that can
be learned on the port Forwarding of frames with unknown destination MAC addresses after the
upper limit of the MAC address table is reached.
Choose the menu Configuration→MAC Constraint to load the following page.
30
Figure 4-3-15
4.3.10 IGMP Snooping
Internet Group Management Protocol Snooping (IGMP Snooping) is a multicast constraining
mechanism that runs on Layer 2 devices to manage and control multicast groups.
The switch, running IGMP Snooping, listens to the IGMP messages transmitted between the host
and the router, and tracks the IGMP messages and the registered port. When receiving IGMP
report message, the switch adds the port to the multicast address table; when the switch listens
to IGMP leave message from the host, the router sends the Group-Specific Query message of the
port to check if other hosts need this multicast, if yes, the router will receive IGMP report
message; if no, the router will receive no response from the hosts and the switch will remove the
port from the multicast address table. The router regularly sends IGMP query messages. After
receiving the IGMP query messages, the switch will remove the port from the multicast address
table if the switch receives no IGMP report message from the host within a period of time.
31
Figure 4-3-16
Unknown multicast data refers to multicast data for which no entries exist in the IGMP Snooping
forwarding table. When the switch receives such multicast traffic:
With the function of dropping unknown multicast data, the switch drops all the unknown
multicast data received.
With the function of forwarding unknown multicast data, the switch floods unknown
multicast data in the VLAN which the unknown multicast data belongs to.
4.3.11 EEE
The switch supports IEEE 802.3az Energy Efficient Ethernet (EEE) for 100Base-TX in full duplex
operation, and supports 10Base-Te for 10Base-T in full/half duplex. The Energy Efficient Ethernet
(EEE) operational mode combines the IEEE 802.3 Media Access Control (MAC) Sub-layer with a
family of Physical Layers defined to Support operation in Low Power Idle (LPI) Mode. When Low
Power Idle Mode is enabled, systems on both sides of the link can disable portions of the
functionality and save power during periods of low link utilization.
The switch EEE operational mode supports IEEE 802.3 MAC operation at 100Mbps. For 100Mbps
operation, the 100Base-TX PHY is supported. In addition, the switch supports a 10Mbps PHY with
reduced transmit amplitude requirements in EEE operational mode. This new PHY is fully
interoperable with legacy 10Base-T PHYs over 100m of Class-D (Category 5) or better cabling.
32
Figure 4-3-17
4.4 Security
4.4.1 MAC Address
A switch maintains a MAC address table for frame forwarding. Each entry in this table contains
the MAC address of a connected device, to which port this device is connected and to which
VLAN the port belongs.
4.4.1.1 MAC Search
A MAC address table consists of two types of entries: static and dynamic. Static entries are
manually configured and never age out. Dynamic entries can be manually configured or
dynamically learned and may age out.
33
Figure 4-3-18
Find Allows the user to move to a sector of the database corresponding to a user
defined port, VLAN, or MAC address.
VID The VLAN ID of the VLAN the port is a member of.
MAC Address The MAC address entered into the address table.
Port The port that the MAC address above corresponds to.
4.4.1.2 MAC Binding
The static address table maintains the static address entries which can be added or removed
manually. In the stable networks, the static MAC address entries can facilitate the switch to
reduce broadcast packets and remarkably enhance the efficiency of packets forwarding without
learning the address. The static MAC address learned by the port in the binding mode will be
displayed in the Static Address Table.
34
Figure 4-3-19
4.4.2 Storm Control Setting
Storm Control function allows the switch to filter Broadcast, Multicast and Unknown Unicast
frame in the network. If the transmission rate of the three kind packets exceeds the set
bandwidth, the packets will be automatically discarded to avoid network broadcast storm.
Choose the menu Security→Storm Control to load the following page.
35
Figure 4-3-20
Storm control is used to stop broadcast, multicast or ARP request storms that may result when a
loop is created. The Destination Look Up Failure control is a method of shutting down a loop
when a storm is formed because a MAC address cannot be located in the Switch’s forwarding
database and it must send a packet to all ports or all ports on a VLAN.
To configure Traffic Control, select the port, you want to configure. Broadcast Storm, Multicast
Storm and Unknown Unicast may be Enabled or Disabled. The Threshold value is the upper
threshold at which the specified traffic control is switched on. This is the number of Broadcast,
Multicast or Unknown Unicast packets, in Kbps, received by the switch that will trigger the storm
traffic control measures. The Threshold value can be set from 0 to100000Kbps.
4.5 Monitoring
4.5.1 Port Statistics
The Traffic Monitor function, monitoring the traffic of each port, is implemented on the Traffic
Summary and Traffic Statistics pages.
Traffic Summary screen displays the traffic information of each port, which facilitates you to
monitor the traffic and analyze the network abnormity.
Choose the menu Monitoring→ Port Statistics to load the following page.
