2: Product Overview

The purpose of IP multicast filtering is to optimize a switched network’s performance, so multicast packets will only be forwarded to those ports containing multicast group hosts members and routers instead of flooding to all ports in the subnet (VLAN).

Routing switches with IP multicast filtering/switching capability not only passively monitor IGMP Query and Report messages, DVMRP Probe messages, PIM, and MOSPF Hello messages; they also actively send IGMP Query messages to learn locations of multicast routers and member hosts in multicast groups within each VLAN.

Note, however, IGMP neither alters nor routes any IP multicast packets. Since IGMP is not concerned with the delivery of IP multicast packets across sub-networks, an external IP multicast router is needed if IP multicast packets have to be routed across different sub-networks.

Switch Management

Administration console via RS-232 serial port

The Xpress-Pro SW 94000 switch provides an onboard serial port, which allows the switch to be configured via a directly connected terminal or a Telnet session.

Web-based browser interface

The Xpress-Pro SW 94000 switch also hosts a point-and-click browser-based interface that lets users access full switch configuration and functionality from a Netscape or Internet Explorer browser.

External SNMP-based network management application

The Xpress-Pro SW 94000 switch can also be configured via SNMP.For more information on switch management, refer to the “Switch Management” section.
