Chapter1 Overview of CiscouBR10012 Universal Broadband Router Software Supported Software Features for the CiscouBR10012 Router
•Restricted QoS class assignment—Allows a CMTS administrator to override the class of service
provisioned for a CM. When this feature is enabled, the user-defined QoS profile is enforced on the
CM attempting to register with the CMTS, regardless of the provisioned class of service.
For additional information about configuring DOCSIS QoS and other DOCSIS features, refer to the
DOCSIS 1.1 Feature Module for the Cisco uBR7200 Routers, or to other documents cited below for
DOCSIS features.
Tip This feature is added to address instances where a cable operator implemented rate limiting
incorrectly. The feature allows an administrator to override the statically provisioned QoS
parameters of the CM and force the CM to use a specific QoS profile defined at the CMTS.
DOCSIS 1.1 Service Flow Manager
The Service Flow Manager is a new module that manages different activities related to service flows on
a cable interface. Typical events include the creation of new DOCSIS service flows, modification of the
attributes of existing service flows, and the deletion of service flows.
Commands
Router# show interface cable x/y service-flow
Router# debug cab qos
DOCSIS 1.1 Service Template and Class Manager
The Service Template and Class Manager is a software module that controls the creation, updating, and
cleanup of various QoS service templates and user-defined service classes on the CMTS.
Commands
Router# show cable service-class
Router(config)# cable service class n
Router# debug cable qos
DOCSIS 1.1 Software Infrastructure
Supports CableLabs specifications for high-speed Data-over-Cable systems involving the following
categories:
•RF interfaces between the CiscouBR10012router and the cable network—Downstream and
upstream traffic.
•Data interfaces for cableinterfaces and CPE devices, as well as the CMTS network-side interface
between the CiscouBR10012router and the data network.
•Operations support interfaces—Network element management layer interfaces between the network
elements and the operations support systems.
•Secure software download allows a service provider to remotely upgrade a CM’s software, without
risk of interception or alteration.
DOCSIS 1.1 Subscriber Management
CMs are assigned to operate on specific cable channels to balance activity across several channels. Each
CiscouBR10012router cableinterface card serves a specific downstream channel and upstream
segment. Part of network planning is to define the channels to use.
In typical cable networks, administrators limit the configuration responsibilities of field service
technicians, and the amount of information collected on subscriber CPE devices. Field service
technicians are sent to subscriber homes or businesses to install the CM or STB and ensure that all
computing devices are DHCP-enabled.
