    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.

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 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.

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.  

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 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.

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.

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.
