This table contains entries that identify lists of
IP Multicast groups for each profile configured on
the device.
Each entry contains a range of contiguous IP
Multicast groups associated to a profile index.
Multiple cIgmpFilterEntry may be associated
with the same cIgmpFilterProfileIndex.
All the cIgmpFilterEntry with the same profile index
are subjected to the same IGMP filtering action as
defined in cIgmpFilterProfileAction.
Each profile index may be associated with zero or more
interfaces through cIgmpFilterInterfaceIfIndex
object in cIgmpFilterInterfaceTable.
The maximum number of entries is determined by
cIgmpFilterMaxProfiles.
