The source address of the IP multicast layer 3 flows.
This object should be instantiated and assigned a
proper IP address whenever the 'source' bit of
cseFlowMcastQueryMask object in the same row is on.
If the 'source' bit is set, and an appropriate IP address
is assigned to this object, then only flows with the
specified source address will be containing in the
result table.
If the 'source' bit in the associated cseFlowMcastQueryMask
is cleared, this object is ignored during the query, and all
flows will be considered regardless of their source IP address.
This object is deprecated and replaced by
cseFlowMcastQueryAddrType and cseFlowMcastQuerySource.
