Early one morning, an engineer end user discovered that the Engineer servers were unreachable, and he didn’t know if he could reach the Internet. The administrator investigated the user’s PC with the IPCONFIG /ALL command and verified that the PC was a DHCP client, but it had received an address from the Accounting DHCP server, not the Engineering DHCP server.

I am a VMware Certified Instructor and every single time I teach, I get questions regarding certification. IT certifications always seem to be a controversial topic, and the question is always, "Why should I become certified?"

Agile is a set of principles requiring a significant cultural shift, new paradigms in thinking and team organization. Over the years, Agile has become "productized" or in many cases "institutionalized", creating different flavours and levels of commitment among teams and organizations. Along the way, managers and team members have lost sight of Agile's principles and tried to enforce the use of certain tools and structure where they may not belong. In this one hour webinar, Perry McLeod will explain how tools such as use cases can be successful in an agile environment, provided the principles of agile are always active in the minds of the managers and the team members that are using them. Join Perry to determine whether or not making the cultural shift towards the use case method in an agile environment is the right move for you and your organization.

Call Admission Control (CAC) is often times included as part of the same topic as Quality of Service (QoS), when in actuality CAC is a separate and complete topic itself. QoS is defined as traffic engineering on a packet switched network. This definition means movin...

When integrating a Voice over IP (VoIP) system into an existing network it is very important to have a good understanding of how much bandwidth is utilized for each call on the network. For most people, just starting out the bandwidth calculations can be a very daunt...

Business and IT alignment is not a one-and-done thing. On the contrary, business strategies and goals continually evolve and cascade down to more specific needs throughout the enterprise — including IT. To stay aligned with the business, the IT side of the house should consistently ensure that it and the business both understand what outcomes are desired in strategic, tactical, and operational contexts. At the same time, IT should build up the disciplines required to enable — and ultimately track — those outcomes.

Business Continuity and Disaster Recovery (BC/DR) planning is the process of developing the plans, processes and procedures to respond to the range of incidents. We start with understanding the essential functions of an organization, called Business Impact Analysis (BIA). In life, we set the same priorities: protection of family and friends, shelter, food and water and other life-giving essentials.

Organizations launch projects with the assumption that the new or improved solution will provide worthwhile benefits for stakeholders and a suitable return on investment. By understanding your business requirements you ensure that your teams actually deliver those benefits. Keeping user and functional requirements aligned with the business requirements is a key to successful solution delivery.

Business processes are complicated, and mapping them is not a trivial task. Modelling standards give us the tools to model complex processes, but they do not tell us the best way to approach a model or effectively use the tool. In this hour-long webinar, Global Knowledge instructor Rod Fage will guide you through the best way to develop a model, from determining the goal and scope of the process and measuring its effectiveness, to modelling the process in a hierarchical top-down approach, enabling business analyst to continuously validate the model.

Every data center has unique hardware and software requirements that can pose significant management challenges to IT. Cloud utilization, virtualization, mobile device management, app development, security, and storage networking represent just a few of the management challenges facing IT today. Add to that the responsibility of providing the infrastructure for processing an exponential increase in data and making it available to an increasingly mobile workforce on a daily basis.

As I’ve stated before, I like Border Gateway Protocol (BGP). I think it’s an interesting protocol, and yes — it’s complicated, but I guess that part of why I like it. There are a lot of knobs to tweak in BGP, maybe too many, but that’s another post. Anyway, we are now running BGP version 4 and it has had extensions written that support more than just IPv4 unicast routing. We now have IPv4 multicast, IPv6 unicast and multicast, VPNv4, VPNv6, and a few others.

This webinar will look at Border Gateway Protocol and explore why we have the protocol; how its involved and how it works. We will look at how and where BGP is used in today’s networks and Internet. We will look at the basics of configuring it and some not so basic configurations.  

In this article, we discuss how to achieve that optimal security approach in the data center with Cisco Application Centric Architecture, or ACI.

In reviewing the list of best-paying jobs in IT, you’ll see some areas you might expect like cloud computing and other areas you probably didn’t, like business technology or enterprise infrastructure management. The top 10 functional areas are based on the 2016 IT Skills and Salary Survey conducted by Global Knowledge in October 2015. Note that all references to “average” represent the mean, not the median or other statistical measures.

For smaller companies, configuring a dial plan to account for variations in dialed numbers is often not a problem. However, companies that are larger and more global in nature encounter a number of issues when designing their dial plan approach.

Projects are a social endeavor. Traditional project management approaches have shied away from the social advantages a more agile project environment brings. By nature, we are storytelling, pattern seeking and social people. We need colocation to shine truly in a project environment.

In this post I’ll focus on a topic that’s mentioned in the Cisco FIREWALL training class but isn’t emphasized there or in the online Cisco ASA documentation. When configuring failover on a pair of ASA security appliances, a situation can arise in which network disruption occurs due to the secondary ASA in a failover pair becoming active first and then the primary comes online second. Both the documentation and the courseware point out that this causes the secondary (and active ASA) to swap its interface MAC addresses with those of the primary. Being naturally skeptical about this behavior, I decided to investigate. The rest of this post illustrates my confirmation of this phenomenon.

The OSI model is a conceptual tool used to discuss and describe network functions. The use of a standard reference model is essential to communicating ideas as well as creating new technologies. It is a good idea to be familiar with the OSI model, the features assigned to each layer, and examples of common protocols or technologies associated with the OSI layers.
