Functional Description 

Jumbo Frame 

 

With Jumbo Frame supported, it is allowed for the switch to transport identical data in 
fewer frames. Hence helps to ensure fewer overheads, shorten processing time, and 
reduce interrupts. 
Note: To enable Jumbo Frame, Flow Control should be enabled in advance.   

 

Flow Control and Back Pressure 

 

Flow control and Back Pressure both contributes for lower and higher speed devices 
to communicate to each other hence ensures the correctness of data transmitting. 
The 802.3x Flow Control and Back Pressure mechanisms work respectively for full 
and half duplex modes. Flow control can be enabled or disabled on a per-port basis. 

 

Mirror 

 

The Mirror function provides network administrator to monitor the traffic. By 
forwarding a copy of the packets that received or transferred by the monitored port, 
the sniffer port received all the packets and hence is able to monitor the traffic of the 
specified port.   

 

VLAN 

 

With VLAN supported, the network can be segmented in groups to reduce the 
collisions from widely broadcasting. The device supports both port-based VLAN and 
802.1Q tag-based VLAN. Port-based VLAN classifies incoming packets to VLANs 
according to their ingress port. The 802.1Q based VLAN add a tag to the header of 
the packet to classify their VLANs. 

 

Trunk (Aggregation) 

 

The Trunk functionality integrates several ports to enlarge the bandwidth that helps to 
boost the backbone connectivity. The switch allows the Maximum 8 group and 8 
members for each group.   

 

Quality of Service (QoS) 

 

The QoS service classifies packets into different precedence. The packets are 
transmitted and received by their classified priorities. This mechanism helps high 
bandwidth demanded applications such as VoIP to get an unobstructed connection.   

 

SNMP  

 

This device is SNMP(Simple Network Management Protocol)-management 
supported. This allows this product to be monitored or inspected by a SNMP 
management station.
