I was going through the packetcable multimedia specs. I came across "Upstream drop classifiers". Can someone let me know why this may be used in the filed?
Thanks in advance.
The legacy RFC4639 IP filter system only supports IPv4, it is not able to filter IPv6
To filter IPv6 you need to switch to using Upstream Drop Classifiers
You cannot run legacy IP filters and UDC at the same time, so all rules need to change over to UDC style
Have a look at these docs on the cablelabs site :
"7 PROVISIONING CPE MANAGEMENT SCENARIOS" of "DOCSIS 3.0 OSSI Configuration Management Technical Report"http://www.cablelabs.org/specifications/CM-TR-OSSIv3.0-CM-V01-08092.pdf
"Annex F Protocol Filtering (Normative)" of "Data-Over-Cable Service Interface Specifications"http://www.cablelabs.org/specifications/CM-SP-OSSIv3.0-I13-101008.pdf
