BenefitsBenefits

Noise free fanless design for home and SOHO users

Home and SOHO users are always working in a small and limited space,

therefore, noise free fanless switch becomes necessary and important.

2 dual media ports for flexible fiber connection

Port 7, 8 dual media ports are provided for flexible fiber connection. You can

select to install optional SFP transceiver modules in these cages for short,
medium or long distance fiber backbone attachment. Use of the SFP will
disable their corresponding built-in 10/100/1000Base-T connections.

QoS supports layer 4 classification

lsoThe switch supports not only Layer 2 802.1p Priority Queue control, but a

supports programmable higher layer classification and prioritization to enable
enhanced Quality of Service (QoS) support for real time applications based on
information taken from Layer 2 to Layer 4, such as VoIP.

Port Mirroring helps supervisor monitoring network

Port mirroring copies traffic from a specific port to a target port. This

mechanism helps track network errors or abnormal packet transmission
without interrupting the flow of data.

Q-in-Q VLAN for performance & security

The VLAN feature in the switch offers the benefits of both security and

performance. VLAN is used to isolate traffic between different users and thus
provides better security. Limiting the broadcast traffic to within the same
VLAN broadcast domain also enhances performance. Q-in-Q, the use of

double VLAN tags is an efficient method for enabling Subscriber Aggregation.
This is very useful in the MAN.

802.3ad Port Trunk for bandwidth aggregation

The Gigabit ports can be combined together to create a multi-link load-

sharing trunk. Up to 4 Gigabit ports can be set up per trunk for bandwidth up
to 8Gbps, all traffic is aggregated based on MAC addresses, thus balancing

the traffic load. The switch supports up to 4 trunking groups. Port trunks are

useful for switch-to-switch cascading, providing very high full-duplex speeds.

802.1x Access control improves network security

802.1x features enable user authentication for each network access attempt.

Port security features allow you to limit the number of MAC addresses per
port in order to control the number of stations for each port. Static MAC
addresses can be defined for each port to ensure only registered machines
are allowed to access. By enabling both of these features, you can establish
an access mechanism based on user and machine identities, as well as
control the number of access stations.

802.1D compatible & 802.1w rapid spanning tree

For mission critical environments with multiple switches supporting STP, you

can configure the switches with a redundant backup bridge path, so
transmission and reception of packets can be guaranteed in event of any
switch on the network.

OverviewOverview

The GS-2108 is an L2 managed Gigabit
switch that supports SNMP, Web UI and
CLI management interface. It is equipped
with 8 Gigabit TP ports and 2 of which are
dual media ports that accommodate
optional 10/100/1000Base-T or SFP
modules. In addition, the switch
implements the QoS (Quality of Service),
Mac Filtering Policy, Port Mirror, VLAN and
full L2 protocol. It is suitable for workgroups
or WAN edge application.

Broadcast/Multicast Storm control

To limit too many broadcast/multicast flooding in the network, broadcast/

multicast storm control is used to traffic. Threshold values are restrict excess
available to control the rate limit for each port. Packets are discarded if the
count exceeds the configured upper threshold.
