L2 Managed Switch
GS-2108C
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
