How do you measure the experience and knowledge of an IT professional? One way is through certifications. Earning any certification is a notable achievement, though not all certifications carry the same perceived worth.

IT is a very fast changing industry – what is hot today may be a tiny niche market in only a few years and lesser known things may turn out to be huge trends. That having been said, there are many certifications that will be around for a long time. However, this does not imply that recertification and/or continuing education credits are not required to maintain certification. Predicting the future is always challenging, including in IT, but these certifications are good bets.

Have you been afraid to implement PowerShell in your environment because of security fears? The reality of PowerShell security doesn’t always match the perception. When compared to other scripting languages, PowerShell is actually more secure by default.

Routers and switches make up the bulk of network infrastructure and are vulnerable to attack. We hear about mass Denial of Service (DOS) attacks or Distributed Denial of Service (DDOS), but the network itself is as big a risk because if it is taken out, there is no path for the data to flow.

Certifications are the most common way in IT to prove you have the skills to solve various technical and business challenges. In this article, I'll address a range of skill sets. For each certification listed, I've included what the certification measures, the requirements to obtain it.

In 2013, Cisco released their Software Defined Networking (SDN) solution for the data center known as Cisco Application Centric Infrastructure (ACI). For many years, the networking industry has been asking for an approach to configuring networking devices more efficiently than having to individually configure each and every router and switch.

The purpose of Interior Routing Protocols (IGP), and routing protocols more generally, is to advertise the existence of destination networks. All protocols then have some method of picking what they would consider to be the best path and maintain the information. By...

What is Network Time Protocol (NTP)? Well, it’s a network protocol used to synchronize clocks between computing systems over a packet switched network. It’s been around since the mid-1980s and was developed by David Mills at the University of Delaware; it is one of the oldest protocols still around on the Internet. NTP replaced other time synchronization technologies that didn’t have some capabilities to adjust time based on location of the time source or time server relative to the receiver or adjusting to the variation of delay found on typical data networks.

Precision Time Protocol (PTP) is a protocol designed to go beyond what Network Time Protocol (NTP) can offer relative to accuracy. PTP is IEEE standard 1588 that can give local computing systems accuracy within the sub-microsecond range (such as microsecond, nanosecond or picoseconds) whereas NTP is within milliseconds or longer. PTP standard was first released in 2002 and known as 1588-2002. In 2008, the IEEE released a revised standard for PTP, known as 1588-2008, that improved the accuracy and precision of the protocol. It is also known as PTPv2 and is not backward compatible with the older version. PTP was developed for packet based network for control and measurement systems.

One size does not always fit all. At times there’s a need to run more than one routing protocol and have more than one routing domain: multivendor shops, migration from one protocol to another, scalability issues of a single protocol, political or personal preference, production versus test networks, mergers, and acquisitions.

Routers and switches make up the bulk of the network infrastructure and are vulnerable to attack. In a previous article, I talked about some of the different ways of hardening your network devices. In this blog, I’d like to specifically examine the routing protocols used on the major Cisco network operating systems.
