Configure and Activate Baseline Privacy

The configuration and activation of baseline privacy depend on each cable operator’s physical plant.

To configure and activate baseline privacy, perform the following tasks:

Configure Kek Encryption Key Privacy

Configure Traffic Encryption Key Privacy

Activate Baseline Privacy

Configure Kek Encryption Key Privacy

To configure kek data privacy on the HFC network, use one of the following command in global configuration mode:

Command

Purpose

cable privacy kek grace-time seconds

Set the cable privacy kek grace time.

or

or

cable privacy kek life-time secods

Set the cable privacy kek life time.

 

 

A grace-time kek can be set from 300 to 1,800 seconds. A life-time kek can be set from 86,400 to 6,048,000 seconds.

Validation Tips

To verify the kek life-time or grace-time values that have been set, enter the show cable privacy kek command:

router# show cable privacy kek

Configured KEK life-time value = 750000

Troubleshooting Tips

If you are having trouble, make sure you have entered a valid value for grace time or life time.

Configure Traffic Encryption Key Privacy

To configure tek data privacy on the HFC network, use the following command in global configuration mode:

Command

Purpose

cable privacy tek grace-time seconds

Set the cable privacy tek grace time.

 

or

cable privacy tek life-time seconds

Set the cable privacy tek life time.

 

 

A grace-time tek can be set from 300 to 1,800 seconds. A life-time tek can be set from 1,800 to 604,800 seconds.

uBR7246 specifications

The Cisco uBR7246 is a versatile edge router designed primarily for cable operators wishing to deliver high-speed Internet, telephony, and video services over hybrid fiber-coaxial (HFC) networks. This router is part of Cisco's extensive line of broadband access solutions, addressing the increasing demand for bandwidth among consumers and businesses alike.

One of the uBR7246's main features is its ability to support a wide range of broadband technologies including DOCSIS (Data Over Cable Service Interface Specification) and EuroDOCSIS. The router is designed to facilitate the delivery of high-speed data services while allowing for flexible configurations that adapt to evolving network technologies. This is crucial for operators looking to maximize their network efficiency and future-proof their infrastructure.

The uBR7246 is equipped with multiple modular slots, enabling service providers to customize the router according to their specific needs. High-capacity interface cards can be added to support various types of connections, such as Ethernet and TDM (Time Division Multiplexing), thus offering scalability. With support for both DOCSIS 1.0 and advanced versions like DOCSIS 3.0 and 3.1, the router can handle increased data rates and offer maximum efficiency in terms of bandwidth utilization.

Security features are integral to the uBR7246, as it employs advanced measures such as encryption and robust authentication protocols to ensure that subscriber data remains secure. This is particularly vital in an era where cyber threats are pervasive, and customer trust is essential.

In terms of performance, the uBR7246 offers exceptional throughput, capable of efficiently managing vast amounts of traffic without degradation of service. Advanced Quality of Service (QoS) mechanisms help prioritize traffic, ensuring that high-demand applications like video streaming and VoIP receive the necessary bandwidth they require for optimal performance.

The router is also designed with operational ease in mind, offering centralized management capabilities through Cisco's suite of management tools. This allows operators to monitor performance, manage configurations, and troubleshoot issues more efficiently, reducing downtime and enhancing service reliability.

In summary, the Cisco uBR7246 is a powerful and flexible solution that meets the demands of modern broadband delivery. Its advanced technologies, modular design, high-level security features, and robust performance make it an ideal choice for cable operators aiming to provide high-quality services to their subscribers while staying ahead of the competition.
