QoS  with  Four  Priority  Queues

    

Extensive QoS features make the solution ideal for real-time 

    applications like VoIP and IPTV. The 4 priority queues together with the
    Weighted Round Robin and Strict Priority scheduling techniques 
    facilitate efficient co-existence of real-time traffic with data traffic 
    allowing them each to meet their QoS needs. Individual users or 
    applications can be prioritized above others using various Class of 
    Service options  by port, layer 2 priority (802.1p), Layer 3 priority (TOS
    or DSCP), IPv6 Traffic Class or TCP/UDP service number.

Enhancing Security,  Traffic  Flow  Classification  and  Prioritize  by

    Powerful ACL rule
   

Access control lists (ACLs) provide an effective means for limiting the

   types of traffic permitted on a network; thus enhancing security by 
   preventing unauthorized activity. ACLs are, as the name implies, a 
   series of lists that are processed for every frame received by the switch. 
   Each list consists of a set of rules. Each rule is defined by a set of 
   criteria. It is the flexibility that the switch allows in configuring these
   lists, rules and criteria that gives the ACLs their power.

Port Mirroring

   

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. 

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. 

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. The switch
   supports up to 8 trunking groups. Port trunks are useful for switch-to-
   switch cascading, providing very high full-duplex speeds. 

Trap Event  for  Exception  Management

   We use SNMP Trap mechanism to inform supervisor to know the instant 
   abnormal status of the switch. 

4 Dual Media  Ports  for  Flexible  Fiber  Connection 

   

The dual media ports are provided for flexible fiber connection. You can

   select to install optional transceiver modules in these slots for short, 
   medium or long distance fiber backbone attachment. Use of the SFP will
   disable their corresponding built-in 10/100/1000Base-T connections.

Build-in Web-base Management

   

Instead of using CLI interface, we provide a more convenient GUI for 

   user. We just need to configure switch via Web Browser. It is more 
   quickly for user to familiar the method to control switch on the basis of 
   this design.
