IGMP Timer Parameters
Robustness Variable The IGMP robustness variable
provides fine-tuning to allow for expected packet loss on
a subnet. The default robustness variable is set to 2. You
might want to increase this value if the subnet is expected
to be lossy.
Query Interval
Set the frequency at which the Switch
sends IGMP host-query messages. (Range: 60-125 seconds;
Default: 12)
Query Response Interval Set the time between receiving
an IGMP Report for an IP multicast address on a port
before the Switch sends an IGMP Query out of that port
and removes the entry from its list. (Range: 5-25; Default:
10)
Last member Query Interval
of time between group-specific query messages, including
those sent in response to leave-group messages. You can
lower this interval to reduce the amount of time it takes a
router to detect the loss of the last member of a group.
Last Member Query Count
of queries issued for which there has been no response
before the Switch takes action to drop a client from the
multicast group. (Range: 2-10; Default: 2)
