DOCSIS 3.0 Operations Support System Interface Specification CM-SP-OSSIv3.0-C01-171207. Contains the value of the IPv4 address of 'S' as the source address for a particular (S,G) IP multicast session. For the case of Any Source Multicast (ASM), this attribute reports a value of 0.0.0.0. Contains the value of the IPv6 address of 'S' as the source address for a particular (S,G) IP multicast session. For the case of Any Source Multicast (ASM), this attribute reports a value of 0::/0. Contains the value of the IPv4 address of 'G' as the group address for a particular (S,G) IP multicast session. Contains The value of the IPv6 address of 'G' as the group address for a particular (S,G) IP multicast session. Contains the value of the Group Service Flow Id. This element is associated with the ServiceIdentifer element from the SAMIS-TYPE-1 and SAMIS-TYPE-2 Service Definition Schemas. Contains the value of the Downstream Service ID (DSID) label with which the CMTS labels all packets of a particular (S,G) IP multicast session. Contains the value of the type of IP multicast session (IGMP, MLD or PIM). reserved IGMP MLD The value of the list of CPE MAC addresses joining the (S,G) IP multicast session. The associated CPE IPv4 and IPv6 address information can be obtained with the CPE-TYPE Service Definition Schema. The value of the UTC time stamp "yyyy-mm-ddThh:mm:ssZ" at the time the IP multicast JOIN request from this CPE for this multicast session was processed by the CMTS. The compact representation of this attribute is the 64-bit Long value of milliseconds since Epoch Time. The value of the UTC time stamp "yyyy-mm-ddThh:mm:ssZ" at the time the “LeaveMulticastSession” request from this CPE for this multicast session was processed by the CMTS or the CMTS determines that this CPE has left the IP multicast session. The compact representation of this attribute is the 64-bit Long value of milliseconds since Epoch Time. If the multicast session is active (i.e. the CMTS has yet to determine that the CPE has left the IP multicast session) when this record is generated, the compact representation of the IpMcastLeaveTime value MUST be set to 0.
