Managing Virtual Switches
The Cisco Nexus 1000V is a virtual access software switch that works with VMware vSphere 4.0 and has the following components:
- Virtual Supervisor Module (VSM)—Control plane of the switch and a virtual machine that runs Cisco NX-OS.
- Virtual Ethernet Module (VEM) —Virtual line card embedded in each VMware vSphere (ESX) host.
Managing a virtual switch involves configuring its domain and server connections.
A domain is an instance of a Cisco Nexus 1000V Series switch device, including dual redundant VSMs and managed VEMs, within a VMware vCenter server. Each domain is distinguished by a unique integer called the domain identifier.
In order for the Cisco Nexus 1000V to connect to a vCenter Server or an ESX server, you must first define the connection parameters. All communication with the vCenter Server is secured by the Transport Layer Security (TLS) protocol.
This chapter in Virtual Device Context Configuration Guide, Cisco DCNM for LAN, Release 7.x describes how to manage virtual switches using Cisco Data Center Network Manager (DCNM).
