Chapter 7 – Configuring Multicast Filtering

Note:

Active mode IGMP is much to be preferred to passive mode, resulting in rapid pruning

of traffic. Use passive mode only with routers that have problems identifying IGMP enabled
switches. A switch running in passive mode requires the presence of a multicast router or it will
not be able to forward multicast streams at all!

Query Interval

In active mode, this is the time interval between IGMP queries sent by the switch.

The query interval also forms the basis for the Group Membership Interval, a
timer that is two query intervals plus 10 seconds in duration. The Group
Membership Interval is used in active and passive mode.

Router Ports

This parameter specifies ports that connect to multicast routers.

Note:

It is important that you configure all router ports or the switch will not know of them.

The switch sends IGMP join messages only to router ports (either statically configured or
dynamically discovered).
