wfIgmpIfQueryRate 1.3.6.1.4.1.18.3.5.3.13.2.1.5

Query rate. This value specifies, in seconds, how often a local group membership is queried. If set to 0, no queries will be sent out this interface, and it should mean that there are no hosts on that interface that want to multicast. This does not mean no multicast traffic will go out this port, as routed mutilcast traffic may use this interface
