Description of Software Features

The switch provides a wide range of advanced performance enhancing

features. Flow control eliminates the loss of packets due to bottlenecks

caused by port saturation. Broadcast storm suppression prevents broadcast

traffic storms from engulfing the network. Port-based VLANs, plus

support for automatic GVRP VLAN registration provide traffic security

and efficient use of network bandwidth. CoS priority queueing ensures the

Broadcast Storm
