IGMP Snooping Configuration
To display the following form, select Layer 3 > IGMP > IGMP Snooping (click the underlined text, not the folder).
Internet Group Management Protocol (IGMP) is used by IP Multicast routers to learn about the existence of host
group members on their directly attached subnet (see RFC 2236).
IGMP Snooping allows the switch to forward multicast traffic only to those ports that request it. IGMP Snooping
prevents multicast traffic from being flooded to all ports. The switch learns which server hosts are interested in
receiving multicast traffic, and forwards it only to ports connected to those servers.
The following table describes the IGMP Snooping Configuration controls:

Control Descriptions
IGMP on? Enables or disables IGMP Snooping.
Set report timeout Configures the timeout value for IGMP Membership Reports (host). Once the timeout value
is reached, the switch removes the host from its IGMP table, if the conditions are met. The
range is from 1 to 255 seconds. The default is 10 seconds.
Set multicast router timeout Configures the timeout value for IGMP Membership Queries (Mrouter). Once the timeout
value is reached, the switch removes the multicast router from its IGMP table, if the proper
conditions are met. The range is from 1 to 255 seconds. The default is 255 seconds.
