This command enables the switch as an IGMP querier. Use the no form to disable it.
Syntax
[ no ] ip igmp snooping querier
Default Setting

Command Mode
Global Configuration
Command Usage
If enabled, the switch will serve as querier if elected. The querier is
responsible for asking hosts if they want to receive multicast traffic.
Example
ip igmp snooping query-count
This command configures the query count. Use the no form to restore the default.
Syntax
ip igmp snooping query-count count
no ip igmp snooping query-count
count - The maximum number of queries issued for which there has been
no response before the switch takes action to drop a client from the
multicast group. (Range: 2-10)
Default Setting
2 times
Command Mode
Global Configuration
Command Usage
The query count defines how long the querier waits for a response from a
multicast client before taking action. If a querier has sent a number of queries
defined by this command, but a client has not responded, a countdown timer
is started using the time defined by
ip igmp snooping query-max-
response-time . If the countdown finishes, and the client still has not
responded, then that client is considered to have left the multicast group.
