Time
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.
• Startup Query Interval
The interval at which startup queries are sent on the selected interface.
• Startup Query Count
The number of queries to be sent on startup.
• Last Member Query
Interval
The last member query interval. The last member query interval is the maximum
response time inserted into group-specific queries sent in response to leave
group messages, and is also the amount of time between group-specific query
messages. This value may be tuned to modify the leave latency of the network. A
reduced value results in reduced time to detect the loss of the last member of a
group. This value is not used for IGMP version 1.
• Last Member Query
Count
The number of queries to be sent on receiving a leave group report.
