Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
This command is only available for VLAN interface configuration. If the system can play the querier role,
the entity will listen for IGMP query packets sent by other devices. If IGMP query message is received,
the device with lower value of IP address becomes the querier.
Example
This example shows how to enable the IGMP snooping querier on VLAN 1.
Switch# configure terminal
Switch(config)# vlan 1
Switch(config-vlan)# ip igmp snooping querier
Switch(config-vlan)#
31-8 ip igmp snooping query-interval
This command is used to configure the interval at which the IGMP snooping querier sends IGMP general
query messages periodically. Use the no form of the command to revert to the default setting.
ip igmp snooping query-interval SECONDS
no ip igmp snooping query-interval
Parameters
SECONDS
Specifies to configure the interval at which the designated router sends
IGMP general-query messages. The range is 1 to 31744.
Default
By default, this value is 125 seconds.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
This command is only available for VLAN interface configuration. The query interval is the interval
between General Queries sent by the Querier. By varying the query interval, an administrator may tune
the number of IGMP messages on the network; larger values cause IGMP Queries to be sent less often.
Example
This example shows how to configure the IGMP snooping query interval to 300 seconds on VLAN 1000.
