Chapter1 Overview of CiscouBR10012 Universal Broadband Router Software
Supported Software Features for the CiscouBR10012 Router
DOCSIS 1.1 Downstream Packet Classifier
Packet classifiers help to map packets into DOCSIS service flows. The CMTS supports downstream IP
packet classifiers.
Commands
Router# show interface cable x/y classifier
Router# show interface cable x/y service-flow [n] classifiers
Router# debug cable qos
For additional command information, refer to the CiscoBroadband Cable Command Reference Guide
on Cisco.com.
DOCSIS 1.1 Downstream Packet Scheduler
The Downstream Packet Scheduler is a new module that controls all output packet queueing service on
the downstream link of each cable interface.
Commands
Router# debug cable qos
Router# show interface cable x/y downstream
For additional command information, refer to the CiscoBroadband Cable Command Reference Guide
on Cisco.com.
DOCSIS 1.1 Dynamic MAC Messages
DSX MAC messages allow dynamic signaling of QoS between the CM and the CMTS. These messages
are DOCSIS link layer equivalents of higher-layer create, modify, and teardown messages. The DSX
state machine module on the CMTS manages the several concurrent dynamic service transactions
between CMs and the CMTS. It include state machine support for all 3 DOCSIS1.1 dynamic MAC
messages (DSX messages):
•Dynamic Service Add (DSA): This message is used to create a new service flow.
•Dynamic Service Change (DSC): This message is used to change the attributes of an existing service flow.
•Dynamic Service Deletion (DSD): This message is used to delete an existing service flow.
Commands
Router# debug cable dynsrv
Router# debug cable tlvs
For additional command information, refer to the CiscoBroadband Cable Command Reference Guide
on Cisco.com.
Note In CiscoIOSRelease12.1(4)CX, only cable-modem-initiated DSX messages are supported.
CMTS-initiated DSX messages are not supported.
DOCSIS 1.1 Enhanced Registration
The registration module has been enhanced to support multiple registration styles
(DOCSIS1.0/DOCSIS1.0+/DOCSIS1.1) in seamless fashion. Besides using services of the new
Tag-Length-Value parser and encoder, this module also supports the conditional
registration-acknowledgment MAC message state machine.
Commands
Router# debug cable registration
Router# debug cable tlvs
