Understanding NPV: Part 1 of a 2-part Series

N-Port Virtualization (NPV), and N-port ID Virtualization (NPIV) have been around for quite some time now. Enhancements have been made to the traditional NPV and NPIV implementations, making it more convenient for unified fabric topologies (which is what we will be discussing today). This blog, part 1 in a 2-part series, will be discussing the ‘fcoe-npv’ implementation of NPV/NPIV, while the next blog will be focused on the traditional implementation. CONTINUE READING

DMVPN for IPv6

As you probably already know, every DMVPN network consists of multiple GRE tunnels that are established dynamically. At the beginning, every Spoke in the Cloud is supposed to build a direct tunnel to the Hub. Then, once the Control Plane converges, the Spokes can possibly build tunnels with other DMVPN device(s), of course assuming that our DMVPN deployment (aka “Phase”) allows for that. 


Connectivity Policies in UCSM

The importance of using templates with Cisco UCS cannot be emphasized enough. Creating something that you can reuse over and over again, as well as update and push out to pre-created objects, can save you a ton of time from an administrative perspective. vNIC and vHBA templates are a great example of this within Cisco UCSM. These templates allow you to create reusable vNIC and vHBA objects that you can reference within the creation of a service-profile template or even a LAN/SAN connectivity pol
