This post is part of my VMware VCIX-NV Study Guide and is about the relation between a VXLAN and a VLAN and the bridge between the two.

Layer-2 Bridging
When you’re talking about Logical Switches, you’re talking about a VXLAN network. VXLAN packets and routing are handled by VTEPs, which are usually ESXi hosts or Top-of-Rack switches. The network packets are inherently different then regular VLAN network packets and … Read more
This post is part of my VMware VCIX-NV Study Guide and covers VXLAN, the backbone of the NSX network. It’s not that much ground to cover, but you should have a very good understanding of how VXLAN is used, how it is built and most importantly, which requirements it has.

What is a Logical Switch?
In previous versions of vSphere, you had two networking options for virtual machines, which were a portgroup on a standard vSwitch or a portgroup on a Distributed vSwitch. These … Read more

What is the Transport Zone?
The Transport Zone is the heart of the VXLAN network. It is the network where the Logical Switches (previously known as portgroups) send their data traffic. It is the network where the ESXi nodes create tunnels between themselves for … Read more

Cisco virtual Port-channels technology is a pretty straight-forward technique: make two switches seem like one switch to a downstream switch, connected with a port-channel. The downstream switch has a single port-channel going upward, which makes the switch high available and eliminating the use of spanning-tree. It looks like this:

In a lab where you have a single Nexus 7000 switch for testing and studying, you would divide it up into VDCs for ultimate usage. OTV, Fabricpath and the … Read more
