Release Notes for Broadband Access Center for Cable Release 2.6


January 30, 2004

These release notes for release 2.6 of Cisco Broadband Access Center for Cable (BACC), introduce a Solaris based software Device Provisioning Engine (DPE) and support for the CableHome technology.

Contents

Introduction

The Broadband Access Center for Cable (BACC) product is a high-speed provisioning application that is easy to install, configure, and maintain. It provides a simple and easy way to deploy high-speed data, voice technology, and home networking technology services.

This provisioning API allows easy integration into an existing operations support system (OSS) environment.

Related Documentation

This release of the BACC product is supported by these related guides:

Broadband Access Center for Cable Administrator's Guide (Release 2.6)

Broadband Access Center for Cable Installation Guide (Release 2.5)

Device Provisioning Engine Recovery CD-ROM Release Notes for Release 2.5

Cisco Content Engine 500 Series Hardware Installation Guide

Cisco Network Registrar User's Guide (Release 6.0)

Cisco Network Registrar CLI Reference (Release 6.0)

System Components

The BACC comprises these major components:

The regional distribution unit (RDU), which is software that you install on your server(s).

The DPE, which is available in two versions:

A software DPE that is installed on a Solaris Sparc computer.

Software that comes pre-installed on rack mountable hardware known as the DPE-590.

A key distribution center (KDC) server used to authenticate MTAs and grant security tickets to them

Cisco Network Registrar DHCP extension points.

An application program interface (API) with which you can integrate BACC with other OSS and billing systems.

An administrator's user interface from which you can monitor and manage BACC.

A sample user interface (SUI) with which you can demonstrate BACC's power and flexibility.

System Requirements

You must have either the Solaris 8 or Solaris 9 operating system and Network Registrar installed on your system to successfully use the BACC software.


Note The use of Network Registrar version 6.1 is required and, although the BACC product will support operation under the Solaris 8 operating system, the Solaris 9 operating system is strongly recommended.


Hardware Considerations

The minimum hardware requirements needed to support both a lab and a fully deployed network are completely described in the Cisco Broadband Access Center for Cable Installation Guide.


Note Processing capacity, disk storage, and memory requirements depend on the size of the network deployment and the amount of log information needed.


Device Provisioning Engine 590

All installation and connection issues are discussed in the 500 Series installation guide that accompanies this product.

New Features

These are the new features built into the BACC 2.6 release:

Solaris Device Provisioning Engine

This BACC release supports the deployment of a DPE on Solaris Sparc computers running Solaris 8 or Solaris 9.


Note The DPE component now requires licenses to be installed at the RDU. If you have not yet received your licenses, contact your Cisco Systems representative before proceeding.


DHCP Option 122 Support

This BACC release now supports DHCP option 122, as specified and approved by both CableLabs and the IETF, for PacketCable EMTA configuration. Option 122, as specified in RFC 3495, replaces the Cablelabs defined DHCP option 177.

CableHome Support

This BACC release supports the non-secure version of this home networking technology. The CableHome technology is herein after referred to as home networking technology.

PacketCable Optimizations

The performance of PacketCable voice technology has been enhanced with this BACC release.

KDC Support

Starting with this BACC release, the KDC is now supported on multiprocessor Solaris computers.

Creation of Configuration File Templates From Binary Files

This features simplifies the process of developing templates through the introduction of a command line interface (CLI) tool that converts binary configuration files (either DOCSIS or PacketCable) into a BACC template.

Installation

As with previous versions of this product, BACC 2.6 has two forms of installation: Lab and component installations. While the differences are clearly described in the Cisco Broadband Access Center for Cable Installation Guide for release 2.5, the introduction of the new Solaris DPE affects the installation process.

Component Installation of a Solaris Device Provisioning Engine

During a component installation, you are prompted to select the components you want to install. With this BACC release, you can now install a DPE component.

Within the Lab Installation process, there are no differences to the installation. In the component installation however, you must select the DPE.

If, during DPE installation, the installation program detects the presence of a TFTP server running on the same computer that the DPE being installed on, the installation is immediately terminated and an error message appears on screen.

During the DPE installation, you are prompted to provide the locations of these directories:

Home Directory

Data Directory

Once you enter this information, refer to chapter 5 of the Cisco Broadband Access Center for Cable Installation Guide and perform the Configuring a Device Provisioning Engine for Data procedure, starting with step 2.


Caution After Solaris DPE installation is complete, you must configure the DPE using the CLI. Refer to the Cisco Broadband Access Center for Cable Administrator's Guide for these configuration instructions. Do not attempt to start the DPE until after you have completed this configuration.

API Installation Component Removed

The installation programs for previous BACC releases provided for the installation of an API component. The installation of this component has been removed in the BACC 2.6 release although the API is still available as in previous releases.

RDU Migration From Previous Releases

This release does not support migration of the RDU database from prior BACC releases. If a previous BACC version is detected during installation, the installation program prompts you to uninstall that version and remove the RDU database.

Bugs

For information on BACC bugs, see the BACC26_BugList.html file in the docs/ subdirectory of the BACC CD-ROM or electronic distribution.

Known Software Problems

Table 1 identifies software issues that are known to exist in this release of BACC.

Table 1 Broadband Access Center for Cable Known Software Problems  

Number
Description
Resolution

CSCdy28813

Any changes you make to the Network Registrar properties at the RDU, are not dynamically propagated to the Network Registrar extension points.

To correct this problem, restart the Network Registrar server so that the extensions re-read the defaults from the RDU.

CSCea79718

When using option-177 to provision MTA devices, a lab installation may fail to return a DHCP offer.

During a lab installation, the installation program populates two optional properties (/pktcbl/dhcp/secondary and /pktcbl/dns/secondary) with empty values in the cnr_ep.properties file. When these optional properties are present, the BACC Network Registrar extensions use empty values in options, if the configuration commands generated by the RDU reference them.

This causes the Network Registrar DHCP server to drop the DHCP offer packet because these values are required to be an IP address.

To correct this, edit the cnr_ep.properties file and enter valid IP addresses for these two properties.

It is generally safe, in a lab installation, to make the secondary properties identical to the primary properties.

CSCed19004

The RDU logs messages containing a null.

Currently this issue has no resolution.

CSCed27889

When a DPE is configured with provisioning enabled on both interfaces, all UDP responses from the DPE may be directed to an interface other than the incoming request. This causes the external requester to reject the response.

To avoid this problem, use only one provisioning interface on each DPE.

CSCed40157

When performing a search using the CPE DHCP Criteria, the results displayed may not be usable.

This search type displays results that include all modems and custom CPEs associated with that CPE DHCP criteria. These modems and custom CPEs are related to the default CPE DHCP Criteria even if they are not in the promiscuous mode. This is not updated if the default CPE DHCP criteria changes.

Do not rely on the search results obtained from CPE DHCP criteria searches, in order to retrieve modems associated with a given CPE DHCP criteria.

CSCed40162

After booting a DOCSIS modem, with a computer behind it, and enabling the promiscuous mode, the computer and the modem should both receive the correct DHCP criteria and class of service. The computer should receive the system default for provisioned promiscuous DHCP criteria.

After disabling the promiscuous mode on the modem, the computer continues to receive the default provisioned promiscuous DHCP criteria rather than the default computer DHCP criteria.

The computers configuration must be manually regenerated to force it to receive the correct service level.

CSCed40628

The BACC API does not validate the value for the cpeDHCPCriteria property. If an invalid DHCP criteria value is entered, a large number of errors will be generated in the RDU logs.

Only enter valid DHCP criteria names as the value for the cpeDHCPCriteria property. Avoid the use of punctuation and space characters.

CSCed49876

The DPE port is susceptible to random packets.

The UDP port that the DPE is configured to listen on should be protected from outside access. For performance reasons, the DPE expects to receive only well-structured messages on this port.

CSCed52904

When PACEConnection objects are continually created and released in the BACC API client, the API client eventually runs out of memory.

When integrating with the BACC API client, open the required number of PACEConnections once, and re-use them. There is no need to release a PACEConnection.

TAC Case Priority Definitions

To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.

Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
