2 dual media ports for flexible fiber connection
Port
15, 16 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 8 Gigabit ports can be set up per trunk for forwarding bandwidth
up to 16Gbps,
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 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.
