Gigabit Switch
BenefitsBenefits
2 dual media ports for flexible fiber connection
Port 23, 24 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
lso The 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 12 Gigabit ports can be set up per trunk for bandwidth up to
24Gbps, all traffic is aggregated based on MAC addresses, thus balancing
the traffic load. The switch supports up to 8 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 failed on
the network.
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.
