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. Untagged (port-based) and

tagged VLANs, plus support for automatic GVRP VLAN registration

provide traffic security and efficient use of network bandwidth. CoS
