queryMode
Enables or disables the querying function of the Internet Group
Management Protocol (IGMP) on Layer 2 Switching Modules. From all
IGMP-capable devices on a given subnetwork, the one with the lowest IP
address is elected as the querier.

Important Considerations
■
The value that you select applies to the entire module.
■
If you enable
igmp querymode
, but disable
igmp snoopmode
, the
module cannot operate as an IGMP querier.
■
To prevent IP multicast traffic from occupying unnecessary bandwidth,
the best device to operate as the querier is the one closest to the
source of IP multicast traffic. You can disable querying on select
devices or manipulate IP addresses with the
bridge multicast igmp
queryIpAddress
command to force this configuration.
■
On Multilayer Switching Modules, IGMP commands exist under the
ip multicast igmp
menu.
