ip igmp query-interval
Overview
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.
NOTE
:
The IGMP query interval must be greater than IGMP query maximum response time.
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.
Examples
The following example changes the period between IGMP host-query messages to
3 minutes (
180
seconds) for VLAN interface vlan20:
awplus#
configure terminal
awplus(config)#
interface vlan20
awplus(config-if)#
ip igmp query-interval 180
