IGMP Snooping

Command Usage
◆ An IGMP general query message is sent by the switch at the interval specified
by this command. When this message is received by downstream hosts, all
receivers build an IGMP report for the multicast groups they have joined.
◆ This command applies when the switch is serving as the querier (page 462), or
as a proxy host when IGMP snooping proxy reporting is enabled (page 461).
Example
Console(config)#ip igmp snooping vlan 1 query-interval 150
Console(config)#
ip igmp snooping vlan
query-resp-intvl
This command configures the maximum time the system waits for a response to
general queries. Use the no form to restore the default.
