IGMP Filtering and Throttling

IGMP Filtering and Throttling
Command Usage
◆
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
snooping command) before a multicast router port can take effect.
Example
The following shows how to configure port 10 as a multicast router port within VLAN
1.
Console(config)#ip igmp snooping vlan 1 mrouter ethernet 1/10
Console(config)#
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.
