set igmp proxy-report
Disables or reenables proxy reporting by an MX switch on one VLAN or all VLANs.
Syntax set igmp proxy-report {enable | disable} [vlan vlan-id]
Defaults Proxy reporting is enabled on all VLANs by default.
Access Enabled.
History Introduced in MSS Version 1.0.
Usage Proxy reporting reduces multicast overhead by sending only one membership report for a
group to the multicast routers and discarding other membership reports for the same group. If you
disable proxy reporting, the MX sends all membership reports to the routers, including multiple
reports for the same group.
Examples The following example disables proxy reporting on VLAN orange:
MX# set igmp proxy-report disable vlan orange
success: change accepted.

set igmp qi
Changes the IGMP query interval timer on one VLAN or all VLANs on an MX.
Syntax set igmp qi seconds [vlan vlan-id]
Defaults The default query interval is 125 seconds.
Access Enabled.
History Introduced in MSS Version 1.0.
Usage The query 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 the set igmp querier command.
Examples The following command changes the query interval on VLAN orange to 100 seconds:
MX# set igmp qi 100 vlan orange
success: change accepted.
enable Enables proxy reporting.
disable Disables proxy reporting.

vlan
