Of course, VMware Host Profiles go some way to achieving this but it’s still lacking in what features in distributed switches. Most large environments rule this out as they need to maintain a consistent configuration across all of their ESX/ESXi hosts. However, the vSS or standard vSwitch, is an individual virtual switch for each ESX/ESXi host and needs to be configured as individual switches. Some of these features include 802.1Q VLAN tagging, egress traffic shaping, basic security, and NIC teaming. Often referred to as vSwitch0, the standard vSwitch is the default virtual switch vSphere offers you, and provides essential networking features for the virtualisation of your environment. Before I jump straight into installing the Nexus 1000V, lets run through the vSphere networking options and some of the reasons you’d want to implement the Nexus 1000V. Installing the Cisco Nexus 1000V distributed virtual switch is not that difficult, once you have learned some new concepts.
