The Robustness Var:[2 ] field allows IGMP to be ‘tuned’ for
sub-networks that are expected to lose a lot of packets. A
high value (max. 255) for the robustness variable will help
compensate for ‘lossy’ sub-networks. A low value (min. 2)
should be used for less ‘lossy’ sub-networks.
Parameter Description
Interface Name:[ ]
Allows the entry of the name of the IP
interface that is to be configured for
IGMP. This must be a previously
configured IP interface.
Querier State:<V2-
Querier>
Can be toggled between V1-Querier and
V2-Querier. This determines the IGMP
version (1 or 2) that will be used to
interpret IGMP queries on the interface.
Robustness
Variable:[ 2]
A tuning variable to allow for
subnetworks that are expected to lose a
large number of packets. A value
between 2 and 255 can be entered, with
larger values being specified for
subnetworks that are expected to lose
larger numbers of packets.
Query Interval:[125 ]
Allows the entry of a value between 1
and 65500 seconds, with a default of 125
seconds. This specifies the length of
time between sending IGMP queries.
Max. Response:[10]
Sets the maximum amount of time
allowed before sending an IGMP
response report. A value between 1 and
25 seconds can be entered, with a
default of 10 seconds.
IP Address:
Displays the IP address corresponding to
the IP interface name entered above.
