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 provide
traffic security and efficient use of network bandwidth. CoS priority
queueing ensures the minimum delay for moving real-time multimedia data
across the network. While multicast filtering provides support for real-time
network applications. Some of the management features are briefly
described below.
