366CHAPTER 11: IGMP SNOOPING COMMANDS

History — Introduced in MSS Version 3.0.

Usage — The query response interval is applicable only when the WX is querier for the subnet. For the WX to become the querier, the pseudo-querier feature must be enabled on the WX and the WX must have the lowest IP address among all the WX switches 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):

WX1200# set igmp qri 50 vlan orange success: change accepted.
