Depending on your network connections, IGMP snooping may not
•
always be able to locate the IGMP querier. Therefore, if the IGMP
querier is a known multicast router or switch connected over the
network to an interface (port or trunk) on this switch, that interface can
be manually configured to join all the current multicast groups.
• IGMP Snooping must be enabled globally on the switch (using the
igmp snooping command) before a multicast router port can take
effect.

The following shows how to configure port 10 as a multicast router port
within VLAN 1.

HROTTLING
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.
