Interface Mode - The administrative status of IGMP on the selected interface.
IP Address - The IP address of the selected interface.
Subnet Mask - The subnet mask for the IP address of the selected interface.
Operational Mode - The operational state of IGMP on the selected interface.
Version - The version of IGMP configured on the selected interface.
Query Interval (sec) - The frequency at which IGMP host-query packets are transmitted on the
selected interface.
Query Max Response Time(1/10 th of a sec) - The maximum query response time advertised in
IGMPv2 queries sent from the selected interface.
Robustness - The robustness parameter for the selected interface. This variable allows tuning for
the expected packet loss on a subnet. If a subnet is expected to be lossy, the robustness variable
may be increased. IGMP is robust to (robustness variable-1) packet losses.
