Command Usage
• IGMP snooping querier is not supported for IGMPv3 snooping (see ip igmp
snooping version, page 33-3).
• 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.
