Table 13-28. IGMP Configuration Subgroup OIDs
Description
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.
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.
Defines the time interval (in seconds) in which the
modem sends out its host membership Query
messages.
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.
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.
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.
Defines which version of the IGMP protocol should
be followed when attempting to join a host group
via an unsolicited report.
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.
Configures the modem to generate an unsolicited
report within a specified time intervals (in seconds)
after joining a host group.
