Cisco Unified Computing Solution (UCS) is a very popular and powerful solution. Cisco continues to provide updated UCS management options for the full range of data center installations.
While there are differences between the IP Multicast configuration in the IOS and the Nexus OS, the Protocol Independent Multicast (PIM) protocol remains fundamentally the same. If you feel comfortable configuring Multicast in the IOS, you should be able to acclimate fairly easily to the changes in the Nexus OS.
Multicast Sparse Mode and its derivatives are supported in the Nexus OS. This white paper explains how it has been implemented in the Nexus platform to provide optimum performance in both virtual PortChannel and FabricPath environments.
The bad guys just keep getting better! No matter how much patching and tweaking we do, the bad guys' constantly changing tactics and techniques continue harming our networks, stealing and damaging data, and just generally screw things up. What motivates someone to do such terrible things in the first place? How have these hackers changed and improved? What kinds of attacks are popular now and why? In this hour-long webinar, security expert, former hacker and Global Knowledge instructor Phillip D. Shade will provide insight into understanding the latest hacking techniques, what the current threat landscape looks like, and suggested countermeasures to mitigate threats. He will include specific examples of the current threat landscape, including data mining, social engineering cyber threat terminology, man-in-the- middle attacks and Denial of Service (DoS) attacks.
IBM Tivoli Endpoint Manager (ITEM) is a product designed to let enterprises automatically manage computers, allowing thousands of them to be managed by just a few support staff.

Nearly every WebSphere administrator has desired a deeper understanding of how passwords are created, used, stored, and encrypted. Learn about the different types of passwords used inside of the WebSphere Application Server and the recovery plans to help restore your server when passwords go awry.
The short answer (and a common one in our industry): it depends. When comparing Cisco IOS with Juniper Junos, the decision to choose one over the other is difficult and often boils down to cost. Of course, there are other factors to consider.
John Barnes, Global Knowledge's Cisco Course Developer, discusses enhancements to our UCS Troubleshooting Boot Camp and suggestions for students in preparation for this course.
SOA is all about architecture-after all, it's right there in the acronym-yet most organizations think it is about turning existing software components into web services. When you adopt SOA, remember that it is all about design and governing that design. It's about how you design your service interfaces, your services, your data model, and your business processes. It's about how you keep track of your services, how you control the design, definition, deployment, and distribution of your services and their artifacts, how you define a service contract and service level agreement for your service consumers, how to secure your services, and how to react when things go wrong with them.
Regardless of your vendor preference or your experience on the Juniper JUNOS CLI, assuming you have a point of reference to another vendor, your first thought when experiencing JUNOS is, “I have been here before.” The CLI is familiar, convenient, and polished. The similarities between JUNOS CLI and another CLI such as Cisco’s IOS are not what I want to focus on here however; it is their differences I want to focus on. But first, when you connect to a JUNOS powered device and access Operational Mode (see Brad Wilson’s blog post Introduction to Juniper Junos), it looks very much like the User EXEC Mode in IOS. In fact, there are a lot of JUNOS commands that are very much like the IOS User EXEC Mode commands.
