430 IGMP Snooping Commands
NN47250-100 (Version 02.51)
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 WSS sends all membership reports to the routers, including multiple reports for the same group.
Examples The following example disables proxy reporting on VLAN orange:
WSS# set igmp proxy-report disable vlan orange
success: change accepted.
See Also show igmp on page 423
set igmp qi
Changes the IGMP query interval timer on one VLAN or all VLANs on a WSS.
Syntax set igmp qi seconds [vlan vlan-id]
Defaults The default query interval is 125 seconds.
Access Enabled.
Usage The query interval is applicable only when the WSS is querier for the subnet. For the switch to
become the querier, the pseudo-querier feature must be enabled on the switch and the switch 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:
WSS# set igmp qi 100 vlan orange
success: change accepted.
