Obtaining Technical Assistance
For all customers, partners, resellers, and distributors who hold valid Cisco service contracts, the Cisco
Technical Assistance Center (TAC) provides 24-hour, award-winning technical support services, online
and over the phone. Cisco.com features the Cisco TAC website as an online starting point for technical
assistance.
Cisco TAC Website
The Cisco TAC website (http://www.cisco.com/tac) provides online documents and tools for
troubleshooting and resolving technical issues with Cisco products and technologies. The Cisco TAC
website is available 24 hours a day, 365 days a year.
Accessing all the tools on the Cisco TAC website requires a Cisco.com user ID and password. If you
have a valid service contract but do not have a login ID or password, register at this URL:
http://tools.cisco.com/RPF/register/register.do
Opening a TAC Case
The online TAC Case Open Tool (http://www.cisco.com/tac/caseopen) is the fastest way to open P3 and P4
cases. (Your network is minimally impaired or you require product information). After you describe your
situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your
issue is not resolved using these recommendations, your case will be assigned to a Cisco TAC engineer.
For P1 or P2 cases (your production network is down or severely degraded) or if you do not have Internet
access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2
cases to help keep your business operations running smoothly.
To open a case by telephone, use one of the following numbers:
Asia-Pacific: [phone] (Australia: 1 800 805 227)
EMEA: [phone]
USA: 1 800 553-2447

Obtaining Additional Publications and Information
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.
Obtaining Additional Publications and Information
Information about Cisco products, technologies, and network solutions is available from various online
and printed sources.

Chapter 1 Supported Platforms and Cisco IOS Releases
The Cable CPE commands operate on the following Cisco cable CPE platforms and Cisco IOS Releases:
Unsupported Cisco IOS Software Commands on the Cisco CMTS
Cisco strongly advises against using unsupported Cisco IOS commands, even if described, because such
commands can have undesirable effects upon the performance of the Cisco CMTS. In particular, Cisco
advises against using any unsupported commands that pertain to service-policy or to Modular Quality of
Service command-line interface (MQC) while Parallel Express Forwarding (PXF) is running ont he
Cisco CMTS. Such commands may cause the Cisco CMTS to hang with unpredictable recovery times.
Cisco IOS Release 12.1(20)EC Cisco uBR7100 series routers,
Cisco uBR7200 series routers
The 12.1 EC train is the Cisco cable-specific early
deployment “stable” DOCSIS 1.0 release train.
Cisco IOS Release 12.0(16)SC3 Cisco uBR7200 series routers The 12.0 SC train was the previous Cisco cable-specific
“stable” release train for Cisco uBR7200 series routers.
This train excludes telco return, DOCSIS 1.0 extensions
support, Cisco UBR7246 VXR clock card feature set,
and the Cisco uBR-MC16S-based hardware and
