Parameter: Interface Query Rate
Path: Configuration Manager > Protocols > IP > Multicast > IGMP > Entry
Default: 120
Options: 0 to 4096 seconds
Function: Specifies how often the router sends group membership queries on the interface.
Instructions: If there are no multicast hosts on this circuit, set the parameter to 0 to disable
queries. Specifying 0 affects queries only. The router still forwards multicast
datagrams on this circuit. If another IGMP router on this network has taken on
the query role, this router will not send queries unless it has not heard of any
queries within the number of seconds specified by the Designated Router
Timeout parameter.
