set igmp qri
Changes the IGMP query response interval timer on one VLAN or all VLANs on an MX.
Syntax
set igmp qri tenth-seconds [vlan vlan-id]
Defaults
The default query response interval is 100 tenths of a second (10 seconds).
Access
Enabled.
History
Introduced in MSS Version 1.0.
Usage
The query response interval is applicable only when the MX is querier for the subnet. For
the MX to become the querier, the pseudo-querier feature must be enabled on the MX and the MX
must have the lowest IP address among all the devices eligible to become a querier. To enable the
pseudo-querier feature, use set igmp querier.
Examples
The following command changes the query response interval on VLAN orange to 50
tenths of a second (5 seconds):
MX# set igmp qri 50 vlan orange
success: change accepted.
