Wrong Queries Read-only. Number of queries received indicating that the
IGMP version does not match the Version value configured
on this interface. IGMP requires all routers on a network to be
configured to operate with the same version of IGMP. If any
queries indicate the wrong version, this indicates a
configuration error.
Joins Read-only. Number of multicast groups joined on this
interface since it was enabled. This parameter reflects the
amount of IGMP activity.
Groups Read-only. Number of current IGMP Groups joined on this
interface.
Router Enables the router to function as either an IGMP Querier
(router) or as an IGMP Host. Select the check box to enable
the router as an IGMP Querier or clear the check box for the
interface to function as an IGMP Host. For the DOCSIS
module, the default is router.
If multiple routers attempt to become the IGMP querier, the
one with the lowest IP address becomes the querier. When
you change an interface from a querier to a host, any
multicast groups that are learned are removed and any
multicast groups joined locally or by an application running
on the Cuda 12000 remain. When you change the interface
from a host to a querier, any multicast groups joined locally
or by an application running on the Cuda 12000 remain.
Note: The DOCSIS module can only be configured as an
IGMP querier (router).
