Baseline Privacy Interface Plus DOCSIS 1.
DOCSIS 1.1 for Cisco uBR905 and Cisco uBR925 Cable Access Routers and Cisco CVA122 Cable Voice Adapters Information About DOCSIS 1.1 Support – Issuer certificate authority (CA) name and signature—Provide a way of verifying that the certificate and keys have not been altered. A DOCSIS 1.
DOCSIS 1.1 for Cisco uBR905 and Cisco uBR925 Cable Access Routers and Cisco CVA122 Cable Voice Adapters Information About DOCSIS 1.1 Support Both sets of keys have a limited lifetime and must be renewed periodically. When a key reaches approximately half its lifespan, the cable modem begins the process to request a new set of keys. While the new set of keys is being exchanged, the cable modem can continue to use the old set to encrypt and decrypt data.
DOCSIS 1.1 for Cisco uBR905 and Cisco uBR925 Cable Access Routers and Cisco CVA122 Cable Voice Adapters Information About DOCSIS 1.1 Support • You must load at least one CVC into the cable modem through the DOCSIS configuration file. The cable modem uses the CVC to verify that a downloaded software image is from the proper manufacturer and has not been altered during transmission.
DOCSIS 1.1 for Cisco uBR905 and Cisco uBR925 Cable Access Routers and Cisco CVA122 Cable Voice Adapters Information About DOCSIS 1.1 Support • Packet classifier—A set of packet header fields used to classify packets onto a service flow to which the classifier belongs. When a packet is presented to the DOCSIS MAC layer at the CMTS or cable modem, it is compared to a set of packet classifiers until a matching classifier is found.
DOCSIS 1.1 for Cisco uBR905 and Cisco uBR925 Cable Access Routers and Cisco CVA122 Cable Voice Adapters Information About DOCSIS 1.1 Support Each service flow has a set of QoS attributes associated with it. These QoS attributes define a particular class of service and determine characteristics such as the maximum bandwidth for the service flow and the priority of its traffic.
DOCSIS 1.1 for Cisco uBR905 and Cisco uBR925 Cable Access Routers and Cisco CVA122 Cable Voice Adapters Information About DOCSIS 1.1 Support The Cisco uBR905 and Cisco uBR925 cable access routers and the Cisco CVA122 Cable Voice Adapter automatically support DCC requests when running Cisco IOS Release 12.2(15)CZ. Dynamic Quality-of-Service DOCSIS 1.1 adds support Dynamic Services MAC-layer messages that provide for Dynamic QoS (DQoS) between the cable modem and the CMTS.
DOCSIS 1.1 for Cisco uBR905 and Cisco uBR925 Cable Access Routers and Cisco CVA122 Cable Voice Adapters Information About DOCSIS 1.1 Support Service Flow Manager The Service Flow Manager is a new module that manages different activities related to service flows on a cable interface.

DOCSIS 1.1 for Cisco uBR905 and Cisco uBR925 Cable Access Routers and Cisco CVA122 Cable Voice Adapters Information About DOCSIS 1.1 Support If a cable modem has not been granted the decryption keys for a particular multicast service flow, it does not forward the traffic to its CPE devices. This ensures that only authorized subscribers can receive the multicast traffic, and prevents cable modems from loading down their local networks by forwarding unnecessary multicast traffic. DOCSIS 1.
DOCSIS 1.1 for Cisco uBR905 and Cisco uBR925 Cable Access Routers and Cisco CVA122 Cable Voice Adapters Information About DOCSIS 1.1 Support For this configuration... The result is...
