igmpSnoopRobustness OBJECT-TYPE
SYNTAX INTEGER -- (1..7)
ACCESS read-write
STATUS mandatory
DESCRIPTION "This variable allows tuning for the expected packet loss on a network.
IGMP is robust to (igmpSnoopRobustness - 1) packet losses.
It is set stack-wide. The default is 2 and the range is 1 to 7."
DEFVAL { 2 }

This enables IGMP tuning on a lossy network if a switch is
the querier. On such a network it may be increased. It is set
stack-wide.
The default value is 2. The range is 1 to 7.
It is used to derive a timeout interval. If no IGMP v2 queries
are heard on this VLAN within this timeout interval, the local
switch will take over the querier role in the VLAN, assuming
the switch has no multicast router ports:
Other Switch Querier Present Interval =
(Robustness x General Query Interval) +
1/2(General Max Query-Response Interval) = 255 seconds by
default
Where the General Query Interval is igmpSnoopQueryTimeout and the
General Max Query-Response Interval is igmpSnoopQueryMaxResponseTime.
The Robustness is also used to derive another interval. The
amount of time that must pass before the querying switch
decides that there are no more hosts listening to a particular
multicast in seconds:
Group Membership Interval =
(Robustness x General Query Interval) +
General Max Query-Response Interval = 260 seconds by
default.

The default value is 1. The range is 1 to 2.
There could be a Low(1) or High(2) setting.
