Release Notes for Cisco uMG9850 QAM Module, Cisco IOS Release 12.2(20)EU2

These release notes describe the features, memory requirements, and hardware and software requirements in Cisco IOS release 12.2(20)EU2 to support the Cisco uMG9850 QAM Module. The Cisco uMG9850 supports the ITU-T J.83 Annex B standard for the delivery of digital video and audio signals.

Note This document supersedes and replaces Release Notes for Cisco uMG9850 QAM Module, Cisco IOS Release 12.2(20)EU1. That software release is no longer available. For more information, see Introduction.

Note Use these release notes with Release Notes for Cisco Catalyst 4500 Series Switch, Cisco IOS Release 12.2(20)EWA, located on Cisco.com. Refer to Obtaining Documentation.

Document History

Introduction

Cisco IOS Release 12.2(20)EU2 is an Early Deployment (ED) release based on Cisco IOS Release 12.2(20)EWA.

Document Version	Date	Notes
1	09/28/2005	This document was first published for Cisco IOS Release 12.2(20)EU2. For more information, see Introduction, below.
2	11/02/2005	DDTS CSCei61732 is documented. See Resolved Caveats—Release 12.2(20)EU2.

This document supersedes and replaces Release Notes for the Cisco uMG9850 QAM Module, Cisco IOS Release 12.2(20)EU1.

Although Cisco IOS Release 12.2(20)EU1 has been removed from CCO, no catastrophic or deferring defect exists. You do not need to upgrade your images. A legacy feature has been removed, and images with that feature are no longer available on CCO. You may continue to operate with existing copies of Cisco IOS Release 12.2(20)EU1 in your network.

Note Cisco IOS Release 12.2(20)EU2 is compatible with Cisco IOS Release 12.2(20)EWA. Cisco IOS Release 12.2(20)EU2 is designed, however, to support the functionality of the Cisco uMG9850 in VoD and digital broadcast applications. Not all features applicable to traditional switching apply to the Cisco uMG9850. For configuration instructions and the command reference for the Cisco uMG9850, refer to Configuring the Cisco uMG9850 QAM Module in Obtaining Documentation.

The Cisco uMG9850, designed for the Cisco Catalyst 4500 series switches, provides video-on-demand (VoD) and digital broadcast services for a hybrid fiber-coaxial (HFC) cable network. It accepts Moving Pictures Expert Group-2 (MPEG-2) digital video from an IP network, and outputs the video as a quadrature amplitude modulated (QAM) RF stream that can be received by digital set-top boxes (STBs) over the cable network.

System Requirements

This section describes the system requirements for Cisco IOS Release 12.2(20)EU2:

Memory Requirements

Minimum memory and flash configurations on the Cisco Catalyst 4500 series switch are sufficient to support the Cisco uMG9850 QAM Module.

Caveats

Caveats describe unexpected behavior in Cisco IOS Release 12.2(20)EU2 specific to the Cisco uMG9850 QAM Module.

Open Caveats—Release 12.2(20)EU2

Simultaneous changes to both PAT and PMT data in unicast session causes an "Invalid PSI" error message to display.

Resolved Caveats—Release 12.2(20)EU2

Through normal software maintenance processes, Cisco is removing deprecated functionality from the OS boot routine. These changes have no impact on system operation or feature availability.

Cisco IOS may permit arbitrary code execution after exploitation of a heap-based buffer overflow vulnerability. Cisco has included additional integrity checks in its software, as further described below, that are intended to reduce the likelihood of arbitrary code execution.

Cisco has made free software available that includes the additional integrity checks for affected customers.

Cisco Product Security Overview

A current list of security advisories and notices for Cisco products is available at this URL:

If you prefer to see advisories and notices as they are updated in real time, you can access a Product Security Incident Response Team Really Simple Syndication (PSIRT RSS) feed from this URL:

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you might have identified a vulnerability in a Cisco product, contact PSIRT:

An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.

Tip

We encourage you to use Pretty Good Privacy (PGP) or a compatible product to encrypt any sensitive information that you send to Cisco. PSIRT can work from encrypted information that is compatible with PGP versions 2.x through 8.x.

Never use a revoked or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

The link on this page has the current PGP key ID in use.

Obtaining Technical Assistance

Cisco Technical Support provides 24-hour-a-day award-winning technical assistance. The Cisco Technical Support & Documentation website on Cisco.com features extensive online support resources. In addition, if you have a valid Cisco service contract, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not have a valid Cisco service contract, contact your reseller.

Cisco Technical Support & Documentation Website

The Cisco Technical Support & Documentation website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, at this URL:

Access to all tools on the Cisco Technical Support & Documentation website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:

Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support & Documentation website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—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.

Severity 2 (S2)—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.

Severity 3 (S3)—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.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
