| Description | This attribute represents the filter group(s) associated
with the CM signaled 'Upstream Drop Classifier Group ID'
encodings during the registration process. UDC Group IDs are
integer values and this attribute reports them as decimal
numbers that are space-separated. The zero-length string indicates
that the CM didn't signal UDC Group IDs.
This attribute provides two functions:
- Communicate the CM the configured UDC Group ID(s), irrespective
of the CM being provisioned to filter upstream traffic based
on IP Filters or UDCs.
- Optionally, and with regards to the CMTS, if the value of the
attribute UdcSentInReqRsp is 'true', indicates that the filtering
rules associated with the Subscriber Management Group ID(s) will
be sent during registration to the CM. It is vendor specific
whether the CMTS updates individual CM UDCs after registration
when rules are changed in the Grp object. |
