The 9000 Series offers several management functions that can be easily configured using a Web Browser, Telnet or a COM port. Internet Group Management Protocol is a feature that allows the 9000 Series switch to forward and filter multicast traffic intelligently. Virtual Local Area Network allows you to segment the switch in order to create two or more separate local area network domains. Quality of Service provides prioritization of network traffic in order to provide better network service. The primary goal of QoS is to improve the latency of prioritized Ethernet packets required for ring management, real-time and other interactive applications.
