CONFIGURING SUBSCRIBER
MANAGEMENT
The Cuda 12000, through Subscriber Management, provides added security
to your cable network against malicious tampering with the cable modem
software, and against unwanted traffic from entering the cable network.
Added security is achieved by providing protocol filtering to and from the
cable modem, and by limiting the number of IP addresses available to
Customer Premise Equipment (CPE) devices.
This section describes Subscriber Management filtering and the following
configuration functions:
■ Viewing Subscriber Management Summary
■ Viewing CPEs Settings
■ Configuring CPEs for Subscriber Management
■ Assigning Subscriber Management Default Filters
■ Configuring Global Subscriber Management Filter Groups
The Cuda 12000 conforms with the DOCSIS 1.1 IETF Subscriber
Management MIB.
About Subscriber Management Filtering
Subscriber Management filtering on the Cuda 12000 requires the following
configuration procedures:
1. You configure global Subscriber Management filter groups. Global filter
groups contain the matching criteria for cable modem packet filters and
for CPE devices. Global filter groups apply across the Cuda 12000 and are
persisted on the Router Server.
2. You use global filter groups to assign default filter groups for use by cable
modems and CPE devices in filtering upstream and downstream traffic
