Multicast Filtering Commands 4

IGMP Filtering and Throttling Commands

In certain switch applications, the administrator may want to control the multicast services that are available to end users. For example, an IP/TV service based on a specific subscription plan. The IGMP filtering feature fulfills this requirement by restricting access to specified multicast services on a switch port and IGMP throttling limits the number of simultaneous multicast groups a port can join.

Command Usage

IGMP filtering enables you to assign a profile to a switch port that specifies multcast groups that are permitted or denied on the port. An IGMP filter profile can contain one or more, or a range of multicast addresses, but only one profile can be assigned to a port. When enabled, IGMP join reports received on the port are checked against the filter profile. If a requested multicast group is permitted, the IGMP join report is forwarded as normal. If a requested multicast group is denied, the IGMP join report is dropped.
