Introduction
General Description
This Switch will instantly boost your networking throughput because it provides
you with 8 Gigabit ports that enable true Gigabit connectivity. Users are now
able to transfer large and bandwidth-hungry files faster and hence get a real
efficiency improvement. This efficiency is further enhanced by the user-friendly
Web-based management interface. In addition to the 8 copper ports, the
Switch offers 1 fiber port that can be used in the place of the nr. 8 copper
port (these are interchangeable or ‘combo’ ports). This mini-GBIC slot
offers the option of a long-distance, fiber-based connection. Use of the
mini-GBIC port automatically disables its corresponding copper port.

Description of Switch Functions
Jumbo Frame
The Switch supports Jumbo Frames, which means that it can transmit the same data
in fewer frames. This helps to ensure fewer overheads, shorter processing time, and
fewer interruptions.
NOTE: To enable Jumbo Frame, Flow Control should be enabled in advance.
Flow Control and Backpressure
Flow Control and Backpressure both help devices with different processing speeds to
communicate with each other. This ensures the correctness of data transmissions.
The 802.3x Flow Control and Backpressure mechanisms work respectively for full-
and half-duplex modes. Flow Control can be enabled or disabled on a per-port basis.
Mirror
The Mirror function enables network administrators to monitor all traffic. By forwarding
a copy of the packets that are transferred by the monitored port, the sniffer port
receives all the packets and hence is able to monitor the traffic through the specified
port.
VLAN
This Switch supports Virtual LAN, which means the network can be segmented into
groups to reduce collisions caused by wide broadcasting. The Switch supports both
port-based VLAN and 802.1q tag-based VLAN. Port-based VLAN directs incoming
packets to VLANs according to their ingress ports. 802.1q-based VLAN adds a tag to
the header of the packet to direct the packet to the right VLAN.
Trunk (Aggregation)
The Trunk function groups several ports into one combined transmission channel.
This increases the bandwidth, which helps to boost backbone connectivity. The
Switch allows a maximum of 4 groups and 8 members for each group.
Quality of Service (QoS)
QoS classifies packets into different precedence classes. The packets are transmitted
and received according to their classified priorities. This mechanism helps
high-bandwidth demanding applications such as VoIP to get an unobstructed
connection.
SNMP
10
The Switch supports SNMP (Simple Network Management Protocol). It allows the
product to be monitored by an SNMP management station.

Management guide

VLAN
VLAN divides the network members into groups to reduce packet collisions and
improve the network efficiency. The switch supports 802.1q tag-based VLAN. Please
follow the instructions to configure.
To add new VLAN groups,
1. Fill in a VLAN ID, from 2 to 4094, in the “VLAN\Port” column.
2. Select the ports for each VLAN group.
3. Click the “Apply” button to execute.
To delete a VLAN group
1. Remove the members of the VLAN group by unmarking their marked
checkboxes.
2. Clear the VLAN ID of the VLAN you want to remove in the “VLAN\Port”
column. (Don’t type N/A. Just leave it blank)
3. Click the “Apply” button to execute.
Note:
1. When a port is configured to a specific VLAN group, a P(ort)V(lan)ID that
corresponds to the VLAN ID will be assigned automatically to this port. (Ex,
when you make port 3 of a VLAN part of VLAN ID “2”, the PVID “2 ” will be
assigned automatically to port 3.)
15
2. Settings in VLAN, Port Aggregation, and Mirror are co-dependent. Please
make sure that the settings won’t influence one another.

PVID
When the VLAN-enabled Switch receives a tagged packet, the packet will be sent to
the port’s default VLAN according to the PVID (port VLAN ID) of the receiving port.
Items Functions
Port Port Number 1~8
Egress Select “tagged” in the drop menu to enable the PVID checking
and tag inserting of one port, and select “untagged” to cancel.
For example, if an Egress-tagged port receives an untagged

Pri-tagged Untagged Pri-tagged Tagged (PVID)
PVID Port VLAN ID(1~4094)
Only
tagged Enable: block all untagged packets from accessing this port. Disable: All packets are allowed to access this port.
16

Aggregation/ Trunk Configuration
To set up the port trunk groups, put the selected ports’ numbers into the same
Aggregation group. You can choose up to eight groups. Don’t forget to click “Apply” to
save the settings.
There are three aggregation modes for you to set up, SMAC, DMAC, and XOR.
SMAC mode selects the path of packets according to Source MAC while DMAC
mode selects path according to Destination MAC. XOR mode calculates the result of
the DMAC and SMAC modes to decide the path of the packets.
