New Reader Tip: Cool Tool for Solving Layer 1 Cable Issues
The Catalyst 2960, 2970, 3560/3560-E, and 3750/3750-E switches have an integrated Time Domain Reflector (TDR), which is used to test cables associated with a port. TDR is supported only on 10/100/1000 and some 10/100 (Catalyst 2960) copper Ethernet ports. It is not supported on 10 GigabitEthernet or SFP module ports.

TDR test started on interface Gi0/2
A TDR test can take a few seconds to run on an interface. Use " show cable-diagnostics tdr " to read the TDR results.

Pair B 21 +/- 4 m N/A Open
Pair C 5 +/- 4 m N/A Open
Pair D 20 +/- 4 m N/A Open

Editor's Note: The above example output shows the results of a TDR test, which was run while the other end of the cable was disconnected (Open). Because the other end of the cable is open, the "Remote pair" mapping is N/A (not available). From the results, we can see that Pair C has a "Pair length" that is much shorter than pair A, B, and D. This suggests there is an open (break) in pair C at the 5 meter point (+/- 4 meters) before the end of the cable (approximately 20 meters +/- 4 meters) is reached.

Introducing Cisco Certified Design Expert Certification
In response to your demand to assess and recognize Senior-Level Network Architecture skills in the market, Cisco is introducing a new premiere knowledge based certification focused on Network Infrastructure Design -- Cisco Certified Design Expert (CCDE).
CCDE is an expert-level certification with content emphasis on expertise in network architecture, which is the capstone for Cisco's design curriculum. In addition, passing the CCDE certification demands competencies of an experienced, seasoned, networking professional with a proven ability to interface with customers at the executive-level and to ensure that business requirements are incorporated into successful designs.
To attain a CCDE certification, a candidate will be tasked with passing two exams:
- Qualification exam (ADVDESIGN) 352-001 -- Requiring no prerequisites, this exam is a two-hour multiple-choice exam that assesses fundamental knowledge of networking theories, principles, protocols, and technology.
- Practical exam -- While still in development, this exam will be an eight-hour, practical scenario-based exam available in late 2008.
Check out the CCDE program page today for more details on the qualification exam. You can also bookmark this page for upcoming practical exam details.
The qualification exam is now available at Pearson VUE testing facilities worldwide, so sign up today.
Submit your questions and feedback regarding CCDE.

Upcoming Technology Terminology Updates to Cisco TSRT
The Cisco TAC Service Request Tool (TSRT) will be updated in the next few days to reflect a technology change under which service requests for Storage Networking products are opened.
In order to consolidate and align for future products, the "Storage Networking" Technology name will become "Data Center and Storage Networking." As a result, all Subtechnologies previously found under "Storage Networking" will reside under "Data Center and Storage Networking." Also under this new category, you will find the new Subtechnology for the Cisco Nexus 7000 Series Switches.
