From the Editor:

Hello,

Before we get to this month's business, here's an interesting story about the Cisco TAC for you. This past December, wildfires blocked road and railway access to Cisco offices in Sydney, Australia, and ice storms cut electricity in Research Triangle Park, North Carolina. What happens when natural disasters hit two major Cisco TAC call centers? Read "Through Fire and Ice, the Cisco TAC Delivers" to find out:

www.cisco.com/tac/newsletter/0103_tac_storms_story.html

This month, the "What's Hot" section of the newsletter covers:

  • Five updated LAN switching technical support documents
  • A new service provider forum at the Networking Professionals Connection
  • The online Cisco TAC Case Query Tool

And the "Online Technical Training Opportunities" section includes:

  • February's schedule of Cisco TAC Web Seminars
  • Upcoming events at the Networking Professionals Connection

Please feel free to forward this newsletter to anyone you know who might find this information useful. Also, if you have any feedback about this newsletter, you can send me e-mail at tacnews-feedback@cisco.com.

What's Hot

LAN Switching Technical Support Documents - UPDATE:
Updated Documents Focus on Cisco Catalyst® Switch Issues

Recent updates to five LAN switching documents on the Cisco TAC Web Site cover software upgrades, Spanning-Tree Protocol, Multilayer Switch Feature Card (MSFC) issues, EtherChannel® technology, virtual LANs (VLANs), and trunking.

Check out these updated documents:

  • "How to Upgrade Software Images on Catalyst Switch Layer 3 Modules" -- Procedures for upgrading a software image on a Catalyst 4000 or Catalyst 4232 Layer 3 Module, Catalyst 5000 Route Switch Module, Catalyst 6000 Multilayer Switch Module, Catalyst 6000 Multilayer Switch Feature Card 1 (MSFC1), and Catalyst 6000 Multilayer Switch Feature Card 2 (MSFC2):
    www.cisco.com/tac/newsletter/0103_upgrade_software_images.html
  • "Understanding and Configuring Spanning-Tree Protocol on Catalyst Switches" -- Spanning-Tree Protocol configuration on Catalyst 2926G, 2948G, 2980G, 4000, 5000, and 6000 switches running the Catalyst OS. These spanning-tree principles apply to almost all devices that support Spanning-Tree Protocol:
    www.cisco.com/tac/newsletter/0103_spanning_tree_protocol.html
  • "How to Recover a Missing MSFC from the Supervisor's 'show module' Command" -- Procedures for recovering an MSFC/MSFC2 using the "show module" command output from the Catalyst 6000 supervisor engine:
    www.cisco.com/tac/newsletter/0103_recover_missing_msfc.html
  • "Understanding EtherChannel Load Balancing and Redundancy on Catalyst Switches" -- An in-depth exploration of the concepts of load balancing and redundancy on Catalyst switches using EtherChannel technology:
    www.cisco.com/tac/newsletter/0103_etherchan_load_bal.html
  • "Configuring InterVLAN Routing and ISL/802.1Q Trunking on a Catalyst 2900XL/3500XL/2950 Switch Using An External Router" -- Scenarios that work with Cisco 2600, 3600, and 4500/4700 Series routers with FastEthernet interfaces, and any Catalyst 2900XL, 3500XL, or 2950 switch:

Networking Professionals Connection - UPDATE:
New Online Discussion Forum Focuses on Service Provider Technologies

You can read about regular schedule updates to the Networking Professionals Connection in the "Online Technical Training Opportunities" section of this newsletter, but here's a special highlight of the site's new discussion forum for service provider technologies.

The Networking Professionals Connection Web site lets you discuss Cisco networking products and technologies with your peers worldwide. At the new Service Providers discussion forum, you can talk online about Metro, Multiprotocol Label Switching (MPLS) over ATM, virtual private network (VPN) service architectures, voice over IP (VoIP), and optical networking.

Visit the Service Providers discussion forum to learn more about Cisco service provider products and services today:

www.cisco.com/tac/newsletter/0103_net_pro_con_svc_prov.html


Cisco TAC Case Query Tool - UPDATE:
Case Query Tool Will Replace Case Update Tool

The online Cisco TAC Case Query tool allows you to update your Cisco TAC cases yourself, adding notes or uploading files, instead of dictating changes to a Cisco representative over the phone. Because this tool now provides the same functions as the Cisco TAC Case Update tool, we plan to remove the Cisco TAC Case Update tool on Friday, March 14, 2003.

The Cisco TAC Case Query tool:

  • Enables you to update a case in less than half the time it takes to call us and have a representative update the case for you.
  • Lets you enter detailed technical notes, and attach configuration or output files to the case.
  • Sends an alert to your TAC engineer and captures your changes in the case history each time you update a case. This detailed case history is particularly helpful if your case is re-queued to another engineer.

Bookmark the Cisco TAC Case Query tool today to track and update your TAC cases as quickly as possible:

(available to registered users only)
