About Subscriber Management Filtering
Subscriber Management filtering on the Cuda 12000 works as follows:
1. You configure groups of Subscriber Management IP packet filters. These
filter groups provide the source-matching criteria for upstream and
downstream traffic for cable modems and CPE devices. These filter
groups are used across the Cuda 12000 and are persisted on the Route
Server.
2. You assign default filter groups for upstream and downstream traffic for
cable modems and CPE devices.
3. During initialization, the cable modem is assigned a filter group that exists
on the provisioning server. (For information about Subscriber
Management configuration on the provisioning server, refer to the
FastFlow Broadband Provisioning Manager Guide, or the guide for your
provisioning manager vendor.)
4. If Subscriber Management filter groups do not exist on the provisioning
server, the cable modem is assigned a default filter group that exists on
the Cuda 12000.
5. The Cuda 12000 supports Subscriber Management filter groups on a per
cable modem basis. If the network administrator chooses not to use the
criteria of the default filter group for a particular cable modem, another
filter group may be assigned on the Cuda 12000 to that cable modem.
Modifications to default filter groups on a per cable modem basis involve
sending SNMP sets directly to the cable modem. The modifications do not
persist, so the default filter group is not overwritten.
