The D6 discovery protocol is part of the Comcast Next Generation on Demand (NGOD) specification. This protocol helps in advertising the video QAM carrier information like frequency, modulation mode, annex, and edge input for the video traffic such as IP address, group name, maximum bandwidth, and so on, to an Edge Resource Manager (ERM). The D6 discovery protocol also sends unique structured names (topological location information) for each edge input or carrier output. From these structured names, and input and RF port numbers, the ERM can infer the topological network location of both the QAM streaming input port (IP) and RF output port (MPEG).

The IPDR CM-STATUS 2008 version is introduced for forward compatibility to support old IPDR collectors. In the IPDR CM-STATUS 2008 version, the CmtsRcsId and CmtsTcsId objects are 16 bits in length whereas in the CM-STATUS version both these objects are 32 bits in length. The CmtsRcsId object in the CM-STATUS-2008 version returns the lower 16 bits of value from the CM-STATUS version. But, the CmtsTcsId object returns the same value for both the CM-STATUS-2008 and CM-STATUS version since the value does not exceed 16 bits in both the schemas.

To simplify and speed up the process of configuring the physical and logical interfaces required to deploy the Cisco cBR router quickly, a service group (SG) profile based approach is adopted.

To configure the interfaces and quickly operationalize the Cisco cBR router, a set of common profiles are created and configured into global service group profiles. These global service group profiles may be applied to fiber node interfaces along with a mapping of the service group interfaces to the physical interfaces.

The following commands were introduced or modified:

• cable profile service-group
• cable fiber-node
• Show cable fiber-node
• Show cable modem fiber-node mac-domain
• Show cable mac-domain fiber-node
• Show cable profile

The Subscriber Traffic Management (STM) feature allows a service provider to configure a maximum bandwidth threshold over a fixed period for a specific service class (or quality of service [QoS] profile). The subscribers who exceed this configured threshold can then be identified and allocated reduced QoS. STM works as a low-CPU alternative to Network-Based Application Recognition (NBAR) and access control lists (ACLs). You can configure the STM feature on the Cisco CMTS routers using the following command:

• cable qos enforce-rule

Cisco CMTS supports downgrading the channel bonding for cable modems and media terminal adapters (MTAs) in battery backup mode. When this feature is enabled and the cable modem enters the battery backup mode, channel bonding is downgraded to one downstream and one upstream channels (battery backup 1x1 mode). This feature reduces the power usage when the cable modem is running on battery backup. When the cable modem returns to the AC power mode, the channel bonding is returned to its original configuration.

The following commands were introduced:

• cable reduction-mode mta-battery
• show cable modem reduction-mode mta-battery

For more information about this feature, see the following URL:

The fatal interrupts received from the hardware components on the line cards result in reset and reload of the line cards, which triggers switchover and partial system downtime. The Downstream and Upstream JIB Partial Reset feature significantly reduces this recovery time.

The line cards support high availability with redundancy schemes. Line card redundancy can help limit customer premises equipment (CPE) downtime by enabling robust automatic switchover and recovery in the event that there is a localized system failure. The Cisco cBR-8 router supports N+1 redundancy scheme for line cards. A single RF Protect PIC can be configured as a secondary card for multiple RF Through PICs (primary cards).

The following commands were introduced or modified:

• class
• description
• linecard-group
• member slot
• redundancy
• redundancy linecard-group switchover from slot
• revertive
• show lcha logging level
• show lcha rfsw
• show redundancy linecard

When an upgrade is done to a package or sub-package, the RF line card must be rebooted. The time taken for the package upgrade on N number of active RF line cards, the total number of reboots would be 2xN. This is time-consuming and may affect services on the rebooting RF line cards. The Cable IOSd Restart feature or Line Card Process Restart (LCPR) supports the restart of specific processes without service disruption and simplified package upgrade without LCHA based reboot.

The following command was introduced:

• request platform software process restart

To address the issue of restricted bandwidth allocation for different application types, admission control can be applied for both normal priority and emergency voice flows. This is done by extending the threshold and assigning a group of application types in a fiber node. Each downstream service flow continues to be categorized to a single application type. However, the one-to-one mapping between an application type and a threshold no longer exists. Each configured threshold and its associated group of application types can thus be treated as a constraint. A service flow categorized to a certain application type must pass all the constraints associated with that application type.

The following command was modified:

• admission-control application-type
