This object indicates a set of PfR policy map entries in
cpfrMapTable associated with the MC. A value of zero indicates
that there is no policy map associated with the MC and that the
values in the default policy should be used for all TCs. The
peer SNMP entity can retrieve this value and retrieve the
cpfrMapEntry rows indexed by this value to understand the PfR
policies. Alternatively the peer SNMP entity can assign the
value of pfrMapIndex to this object to associate a set of
policies to MC.
