ip igmp query-interval

Use this command to configure the period for sending IGMP General Query messages.
The IGMP query interval specifies the time between IGMP General Query messages being
sent.

Use the no variant of this command to return to the default query interval period.

Syntax

ip igmp query-interval <interval>

no ip igmp query-interval

Default

The default IGMP query interval is 125 seconds.

Mode

Interface Configuration for a VLAN interface.

Usage

This command applies to interfaces configured for IGMP. Note that the IGMP query
interval is automatically set to a greater value than the IGMP query max response time.

For example, if you set the IGMP query max response time to 2 seconds using the

ip igmp

query-max-response-time

command, and the IGMP query interval is currently less than

3 seconds, then the IGMP query interval period will be automatically reconfigured to be 3
seconds, so it is greater than the IGMP query maximum response time.

Use the ip igmp query-interval command when a non-default interval for IGMP General
Query messages is required.

The

ip igmp query-holdtime

command can occasionally delay the sending of IGMP

Queries.

Ensure your VLAN is configured first: see

Chapter 16, Configuring VLANs

Examples

The following example changes the period between IGMP host-query messages to
3 minutes (180 seconds) for VLAN interface vlan20:

The following example resets the period between sending IGMP host-query messages to
the default (125 seconds) for VLAN interface vlan20:

Note

The IGMP query interval must be greater than IGMP query maximum response
time.
