When the IPv4 management address is not set, system uses the first available IPv4 management address.

Otherwise, system uses a pre-defined value. By default, this value will be 192.0.2.1.

Compatibility Compatibility is maintained by hosts and routers taking appropriate actions depending on the versions of IGMP operating on hosts and routers within a network.

The allowed selection is IGMP-Auto, Forced IGMPv1, Forced IGMPv2, Forced IGMPv3, default compatibility value is IGMP-Auto.

PRI Priority of Interface. It indicates the IGMP control frame priority level generated by the system. These values can be used to prioritize different classes of traffic.

The allowed range is 0 (best effort) to 7 (highest). Default interface priority value is 0.

RV Robustness Variable. Allows tuning for the expected packet loss on a network. Valid values are 1 – 255. Default is 2.
QI Query Interval. The Query Interval is the interval between General Queries sent by the Querier.

Valid values are 1 – 31744 seconds. Default is 125 seconds.

QRI Query Response Interval. It is used to calculate the Maximum Response Code inserted into the periodic General Queries.

Valid values are 0 – 31744 in tenths of seconds. Default is 100 in tenths of seconds (10 seconds).

LLQI(LMQI for IGMP) Last Member Query Interval. The time value represented by the Last Member Query Interval, multiplied by the Last Member Query Count.
