Ip Snooping Vlan Querier - Fujitsu XG1200 User Manual

XG1200 User's Guide

5.13.10 ip snooping vlan querier

Function
The IGMP Querier function sends an IGMP General Query message to each terminal instead of the multicast router if no
multicast router exists in a network segment.
This command enables the IGMP querier. The query message transmission interval (called "Query interval") is calculated
based on the query message transmission frequency and the group valid time (called "Group member interval") as follows.
Query interval = (Group-membership-interval – 10) / send-query-count (seconds)
XG1200 does not send Query messages when there is a multicast router in the network.
Use the no form to return to the default setup.
