11.4.1.14.1 IGMP Configuration Subgroup
Note: This subgroup will only be accessible in the MIB tree if the IGMP FAST feature has been
purchased and activated. Otherwise, both gets and sets on these OIDs will return errors.
Table 11-28. IGMP Configuration Subgroup OIDs
OID Description
cimIgmpTable Reports the host groups being routed by the modem.
This table shows the minimum time before a host group
will be put out of service.
cimIgmpEnable Allows a user to enable or disable the IGMP feature.
When enabled, multicast packets received from the
Satellite Interface are forwarded to the Ethernet
Interface if a host on the Ethernet LAN has joined the
host group via an IGMP report.
cimIgmpQueryPeriod Defines the time interval (in seconds) in which the
modem sends out its host membership Query
messages.
cimIgmpMaxRespTime Defines the time interval (in seconds) that the modem
waits before it assumes that no hosts are interested in
the membership query. The max response time is 25
seconds.
cimIgmpMaxMissBeforeDrop Number of unanswered queries that must occur before
the modem assume that that group has no local
members and that it need not forward remotely-
originated multicasts for that group onto the local
network.
cimIgmpRecognizeQueries Allows the modem to respond to a Query by generating
Host Membership Reports, telling each host group to
which it belongs on the network interface from which
the Query was received.
cimIgmpVersionUnsolicitedReports Defines which version of the IGMP protocol should be
followed when attempting to join a host group via an
unsolicited report.
cimIgmpForceAlertOption Provides a mechanism whereby routers can intercept
packets not addressed to them directly, without
incurring any significant performance penalty. Some
Cisco routers may require the definition of a Router
Alert Option to recognize a report from a host to join a
host group.
cimIgmpUnsolicitedReportInterval Configures the modem to generate an unsolicited
report within a specified time intervals (in seconds)
after joining a host group.
