Multimedia Traffic Control with IP Multicast (IGMP)

CLI: Configuring and Displaying IGMP

Querier Capability: The switch performs this function for IGMP on
I
VLANs having an IP address when there is no other device in the VLAN
acting as querier. See "Querier Operation" on page 12-18.
Whenever IGMP is enabled, the switch generates an Event Log message
indicating whether querier functionality is enabled.
IP multicast traffic groups are identified by IP addresses in the range of
224.0.0.0 to 239.255.255.255. Also, incoming IGMP packets intended for
reserved, or "well-known" multicast addresses automatically flood through all
ports (except the port on which the packets entered the switch). For more on
this topic, see "Excluding Well-Known or Reserved Multicast Addresses from
IP Multicast Filtering" on page 12-19.
For more information, refer to "How IGMP Operates" on page 12-11.
