From the Editor:
Since the launch of the redesigned Cisco.com Web site and Cisco TAC Web Site, many of you have been saying, "Ok, it's a new site, but how do I get to the troubleshooting pages fast?" Here's how:

At www.cisco.com, click "Technical Support" to access the Cisco TAC Web Site, or go directly to www.cisco.com/tac. Here you can navigate through the hardware, software, or technology sections to find technical tips, sample configurations, and field notices, as well as TAC Web tools and utilities.

By the way, thanks to all of you for your patience through the recent transitions. I know it's frustrating to have to learn a new interface, and we appreciate your willingness to work with us. If you have other questions about using the TAC Web Site that you'd like me to address in next month's newsletter, send me e-mail at tacnews-feedback@cisco.com, and I'll post the two or three most frequently raised issues.

Now, on to this month's business. Here are the topics in this issue of the Cisco TAC Newsletter:

  • The Cisco Output Interpreter tool's new support for the "show stack" command
  • Updates to our router support resources
  • Updated Cisco TAC Web Seminars, where you can learn about using the TAC Web Site
  • Online discussions at the Networking Professionals Connection
  • CCIE® Network Security certification

As always, please feel free to forward this message to your friends or coworkers (or both!) who would be interested.

Cisco TAC News Editor

What's Hot

Cisco Output Interpreter Tool - UPDATE:
Output Interpreter Now Incorporates Stack Decoder Functionality

The Cisco Output Interpreter tool provides an instant, online analysis of the output from more than 100 key "show" commands, now including "show stack." Next time you encounter an unexpected reload, paste the output of "show stack" into the Output Interpreter's text field. The tool will compare your output to the Cisco TAC's database of known bugs, then list bugs that may have caused the reload.

You may be aware that the Cisco Stack Decoder tool also provides this functionality. Because both tools now do the same thing, we plan to remove the Stack Decoder page from the Cisco TAC Web Site on December 6, 2002. From that point on, make sure to use the Output Interpreter for stack decoding.

But there's no need to wait -- give the Output Interpreter's new "show stack" support a try today:

(available to registered users only)


Cisco Router Technical Support Documents - UPDATE:
Expanded Online Support for Cisco Router and Software Issues

The Cisco TAC Web Site has several new and updated documents that focus on technical support for Cisco routers and Cisco IOS® issues.

Online Technical Training Opportunities

Cisco TAC Web Seminars - UPDATE:
Updates to Voice, Router, and IP Routing Protocol Seminars

The online Cisco TAC Web Seminars offer the best way to learn about using the redesigned Cisco TAC Web Site. These free seminars will show you how to navigate the site to access technical tips, sample configurations, field notices, software documentation, and online utilities such as the Cisco Bug Toolkit and the Cisco TAC Case Open tool.

Our three updated seminars are:

  • "Using the Cisco TAC Web Site for Voice, Telephony, and Messaging Issues" -- This seminar follows the typical life cycle of an IP telephony installation. Learn where to find TAC Web tools and documents for planning and design, implementation, troubleshooting (one-way voice issues, no ringback, fax troubleshooting), and operational issues (Cisco CallManager service crash, Structured Query Language replication).


  • "Using the Cisco TAC Web Site for General Router Issues" -- This seminar will show you how to find information to resolve router hardware, software, and maintenance issues. Learn how to troubleshoot memory problems, system crashes, high CPU utilization, and error messages.


  • "Using the Cisco TAC Web Site for IP Routing Protocol Issues" -- This seminar demonstrates how to use TAC Web tools and technical documentation for installing, configuring, and troubleshooting IP routing protocols. Learn how to find resources for verifying network address translation operation, IP addressing, subnetting, and much more.

Register for a live or on-demand seminar today at the Cisco TAC Web Seminars site:

CCIE® Central

CCIE Network Security Certification - UPDATE:
Worldwide Testing Centers Now Offer Network Security Certification

The CCIE program now offers CCIE Network Security certification in lab testing centers worldwide. This certification gives you an excellent opportunity to demonstrate your technical expertise, and can serve as an alternative to other CCIE designations toward fulfilling Cisco partner requirements.

In the CCIE Network Security lab examination, candidates must successfully secure an enterprise network, implementing firewalls, intrusion detection, authentication servers, routers, and switches. Candidates must also configure network devices to interact with pre-configured systems running authentication, authorization, and accounting (AAA), certification authority, and Cisco Secure Intrusion Detection System.

Visit the CCIE Web site for details about CCIE Network Security certification:
