GS-2108C: 8-Port GbE L2 Managed Switch with 2 SFP Dual Media  
Benefits  
Noise free fanless design for home and SOHO users  
Key Features  
Standard Compliance  
---IEEE 802.3x flow control capability  
---IEEE 802.1q VLAN  
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  
---IEEE 802.1p QoS  
RoHS Compliance  
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  
Performance  
Switching Capacity:  
---8 Gigabit Ethernet ports with non-  
blocking wire speed performance  
---8 K MAC addresses  
The switch supports not only Layer 2 802.1p Priority Queue control, but also  
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.  
---144KB on-chip frame buffer  
---Supports Jumbo frame, up to 9K  
---Broadcast/Multicast Storm  
Suppression  
Port Mirroring helps supervisor monitoring network  
---Port Mirroring  
VLAN  
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.  
---Port-base VLAN  
---IEEE802.1q tag-base VLAN, up to 256  
active VLANs  
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.  
---Q-in-Q is an efficient method for  
enabling Subscriber Aggregation.  
VSM(Virtual Stacking Management)  
---Up to 16 Switches can be managed  
via Single IP  
----Virtual stacking, no extra stacking  
hardware is required  
802.3ad Port Trunk for bandwidth aggregation  
----Distributed stack, no physical central  
wiring closet is needed  
QoS  
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  
---Supports Layer 4 TCP/UDP port and  
ToS classification  
---Supports 802.1p QoS with two level  
priority queue  
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.  
---Supports priority in a Q-in-Q tag  
Bandwidth Control  
---Supports bandwidth rating per port  
ingress and egress rate limit 1000  
Mbps with 1Mbps increment  
Protocol  
LACP  
802.1D compatible & 802.1w rapid spanning tree  
---Port trunking with 4 trunking groups  
---up to 8 ports for each group  
GVRP/GARP  
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.  
---802.1q with GVRP/ GARP  
Multicasting  
---Supports IGMP snooping including  
active and passive modes
