What's Hot
Announcing the Cisco Technology Pages!
The Most Comprehensive, Authoritative Technology Resource
 

The Cisco Technology Pages provide access to comprehensive technical information and online tools that you need to configure, verify, troubleshoot, and learn more about key networking technologies. This valuable new TAC resource provides access to the same content used by Cisco TAC Engineers to help you save time, resolve issues quickly, and maximize network performance.

The Cisco Technology Pages currently deliver support content on the following technologies:

  • Access/Dial
  • IP Routing Protocols
  • Security
  • LAN switching

Additional technology categories will soon be added to the Cisco Technology Pages as support content is developed, edited, and lab-tested by Cisco TAC Engineers.

Check out the new Cisco Technology Pages at: www.cisco.com/tac

Announcing the Cisco Output Interpreter Tool!
 

The Cisco Output Interpreter tool is a new online application that helps you identify, troubleshoot, and resolve a variety of Access/Dial and ATM router issues quickly and easily. Begin by copying your router "show" command data into an online form. The Output Interpreter tool then diagnoses the data, delivers a report, and offers suggestions for problem resolution. Cisco TAC Engineers regularly update the Output Interpreter tool's template library of "show" commands. Increase your productivity and issue-resolution speed with this powerful new tool from the Cisco Technical Assistance Center!

ROUTING
 

Tech Tip:
How Does the Passive Interface Feature Work in EIGRP?

On EIGRP, the passive interface feature causes the router to stop sending hello packets. When this happens, the router can't form neighbor adjacencies on the interface or send or receive routing updates. To achieve the usual effect of passive interface with EIGRP, use the distribute-list command.

http://www.cisco.com/warp/customer/104/24.html (available to registered users)

 

Tech Tip:
Why Doesn't OSPF Form Adjacency on a PRI, BRI, or Dialer Interface?

The OSPF network type on Primary Rate Interface (PRI), Basic Rate Interface (BRI), and dialer interfaces is point to point, meaning that an interface can't form adjacency with more than one neighbor. A common problem when PRI, BRI, or dialer interfaces try to form an OSPF adjacency is that the neighbor gets stuck in the exstart/exchange process.
http://www.cisco.com/warp/customer/104/20.html (available to registered users)

 

Tech Tip:
What Do "%OSPF-4-ERRRCV" Error Messages Mean?

The "%OSPF-4-ERRRCV" error message indicates that an OSPF router has received an invalid OSPF packet. The cause of the error is included in the error message itself. The most common causes of the %OSPF-4-ERRRCV error message are discussed in detail.

MIBS Files Now Easier to Download!

To assist customers with the download of Management Information Base (MIB) files from ftp.cisco.com, at each directory level that contains multiple files we have taken all the files located in that directory and compressed them into a single file (via gzip) for easy download. To easily identify the appropriate tar file, the file name is derived from the directory name. For example, under the directory /pub/mibs/v2/ the tar'ed file is called 'v2.tar.gz'. All tar files under the MIBS directory are updated nightly.

"I really enjoy the TAC newsletter. It is of great help to me, because I do not have the time to research [issues] on CCO. The listing with links to various items is really nice. It enables me to spend half an hour to read the newsletter and surf the CCO site. I learn about many things which would otherwise be 'put off' due to time constraints."
