From the Editor


Welcome to the second October issue of the Cisco TAC Newsletter!

The interactive Cisco TAC Case Collection tool available at the Cisco TAC Website is a great place to start when you need to troubleshoot a networking issue. This newsletter includes a feature article about the router and IOS architecture, and IP routing support now available from this popular diagnostic tool. You'll find this feature article immediately after my signature below.

Here are the other topics we'll cover in this issue:

  • Using the "Search" field to find bug and TAC case details
  • Upcoming events at Networking Professionals Connection
  • Recent changes to the CCIE program

Please feel free to send this message to anyone you know who might find this information useful. And, if you have any questions or comments about this newsletter, you can e-mail me at

Cisco TAC Case Collection Tool:
New Support for Router and IOS® Architecture, and IP Routing Issues

The online Cisco TAC Case Collection tool can help you quickly find solutions to common issues and questions related to Cisco products and technologies, based on symptoms you describe. Using information from recent technical support cases, our engineers have added two new knowledge bases to this interactive tool: Router and IOS Architecture, and IP Routing Protocols.

The Router and IOS Architecture knowledge base can help you diagnose and troubleshoot common hardware and software problems with a variety of Cisco routers and access servers. The knowledge base addresses some of the most common issues, error messages, and warnings, including:

  • boot issues
  • Cisco IOS software and boot image installation and upgrades
  • connectivity through Telnet, aux port, and console
  • crashes, reloads, and hangs
  • logging
  • memory issues
  • non-working hardware components
  • password recovery
  • performance issues

The IP Routing Protocols knowledge base contains diagnostic information that can help you address common issues with:

  • IP routing protocols (BGP/OSPF/EIGRP/RIP) and multicast
  • Network Address Translation (NAT)
  • policy-based routing issues
  • Hot Standby Router Protocol (HSRP)
  • error messages related to IP routing protocols, HSRP, and NAT
  • routes missing from routing table
  • route not being redistributed
  • route not forwarding packet
  • network not being propagated or advertised
  • neighbor not forming/flapping
  • Internet and network connectivity

In addition to these two new knowledge bases, the TAC Case Collection also supports dial (access), frame relay, LAN switching, network security, voice quality, and wireless technologies.

Check out the TAC Case Collection knowledge bases today at:
(available to registered users only)

Note: Due to the dynamic nature of the content in the Cisco TAC Case Collection, you should access the tool with Microsoft Internet Explorer 5.5, Netscape 6.0, or later.

Other News Search - UPDATE:
Use the "Search" Field to Find Bug and TAC Case Details

Did you know you can use the "Search" field in the upper-right corner of all pages to retrieve individual software bugs and TAC cases? If you have the bug ID or case number in which you're interested, the "Search" field is one of the fastest ways to find the information you need.

  • Enter a bug ID in the "Search" field and your results will include a link to that bug. Click the link to view the bug details in the Cisco Bug Toolkit, a tool that identifies known bugs by ID, Cisco IOS release, and software/hardware product name.

  • Enter a TAC case number in the "Search" field and your results will include a link to that case. Click the link to access the case in the Cisco TAC Case Query tool, which allows you to check the status of your cases, add notes and attachments, and view general case information.

You'll find bug and case links above the regular search results, in a section called "Best Bets." After you click one of these links, you'll need to log in with your user ID and password to access the tool.

CCIE® Central - UPDATE:
New Voice Lab, C&S Track Renamed

The CCIE program has recently opened a new lab for Voice exams and renamed the Communications and Services (C&S) track.

Here's a summary of these changes:

  • New Voice Lab -- In September, the CCIE program opened the first lab to certify networking professionals in enterprise Voice-over-IP solutions. This lab, located in San Jose, CA, is designed to meet the growing need for experts who can tackle the most challenging issues with voice communications carried over data networks. Before taking the hands-on Voice lab exam, CCIE candidates must first pass a written exam offered by Cisco authorized testing centers worldwide.

  • C&S Certification Track Renamed -- The C&S certification track is now called "CCIE Service Provider." Certification in the CCIE Service Provider track indicates expert-level knowledge and skill in the fundamentals of IP and core IP technologies, as well as specialized knowledge in at least one of the networking areas specific to service providers (Dial, DSL, Cable, Optical, WAN Switching, and IP Telephony).

For more information on the CCIE program and to sign up for exams, visit the recently redesigned CCIE website at the following URL:
