3
.
Query Interval
Enter the interval (in seconds) at which the multicast router sends a query messages to
hosts. the default is
125
.
Note:
If you enter a number below 128, the value is used directly. If you enter a number
128, it is interpreted as an exponent and mantissa.
Query Response Inter-
val
Upon receiving a query packet, a host begins counting down seconds, from a random num-
ber. When the timer expires, the host sends its report. The default is
10
seconds.
Enter the maximum number of seconds that a host can pick to count down from. The
value must be greater than the
Query Interval
. If using IGMP v1, this value is fixed at
10
seconds.
Last Member Query
Interval
Enter the maximum response time (in seconds) within which the host must respond to the
Out of Sequence query from the router. The default is
10
seconds.
IGMP uses this value when the router receives an IGMPv2 Leave report indicating at least
one host wants to leave the group. Upon receiving the Leave report, the router verifies
whether the interface is configured for IGMP Immediate Leave. If not, the router sends
the out-of-sequence query.
Robustness Value
Enter the value representing the complexity of the query. The greater the value, the
more robust the query. Options are
2
-
7
. The default is
2
.
