To enable back-to-back communication over the Serial interfaces you have to perform a few tasks. These tasks are fairly straight forward as soon as you fathom things out. The first thing to do is to ascertain which is the DTE and which is the DCE interface. This can be done by physically looking at the cable connector type. If you are using X21 then the female connector is the DCE end.

Cisco added a new member to its lineup of IP Telephony certifications in its Cisco Qualified Specialist program. Called the Cisco Unified Communications Design Specialist credential, this program concentrates on the growing convergence between IP networks, telephony, and messaging services—particularly, those based on MS Exchange Server 2000 or 2003. That's why, in addition to requiring candidates to earn the CCDA certification as a prerequisite, the company strongly recommends that candidates hold the MCSE credential for Windows 2000 or Windows Server 2003, with some additional background in related versions of MS Exchange Server.

For a while now, Cisco certified professionals have had to re-up their credentials every two or three years, depending on which credentials they hold. For associate- and professional-level credentials, this happens every three years; for CCIE and Qualified Specialist credentials, this happens every two years. Certified Cisco professionals used to have two primary options to keep their credentials current.

The much undersung Cisco Networking Academy Program brings CCNA training to high schools (and even some middle schools) in over 40 of the 50 U.S. states, according to the program's Web pages. In early November, I had the good fortune to interview Gene Longo, director of the Cisco Networking Academy Program, who helped me to understand that program's offerings and intent.

Some exam study guides would have you believe there is only one way to send data through a network: packet switching. Fact is, there’s at least one other way, circuit switching.While the majority of switched networks today get data across the network through packet switching, the concept of circuit switching should be no mystery to the average tech, let alone the tech wannabe.

Cramsession gets thousands of visitors that are considering career changes within the IT certification world. Many of the first questions asked have to do with the cost of new courses or the degree of difficulty of the exam but one of the most consideration that is often overlooked is the economics of the matter.

Imagine for a second that you’re a frame of data (sure this is unlikely, but still). You’ve been packaged slowly down the OSI layers, and are now finally ready to take that big step into the wide world of the Ethernet. With its crazy and often chaotic flow of data, is there any guarantee that you’ll make it to your destination, or is there no control in this world?

I am of the opinion that all routers are female. Must be. Look at the relatively high male to female tech ratio in IT. Gotta be the routers. Obviously, I could be wrong, but a router's anatomy is interesting all the same. Let's take a closer look.The first thing you should know about a router is she has a lot in common with the PC on your desk.

It's been coming for some time now. I can remember hearing about IPv6 ages ago. Last week in an article I read on the web, Cisco announced that their 12000 series routers are being used on the first native IPv6 Internet network in Europe. Official support for IPv6 began with IOS version 12.2(1)T. It looks like it is inevitable--I'm going to have to learn about IPv6 sooner rather than later. This week's newsletter will be a brief introduction to IPv6, followed by some helpful links for the curious.
