14 Network Virtualization with Dell Infrastructure and VMware NSX | Version 1.2

The vCenter server also utilizes the management plane to manage the ESXi hosts via the Message Bus

Agent (MBA). It’s important to note the NSX Manager, vCenter, and NSX controllers all sit on the

management network.

Additionally, a cloud management platform such as vCloud Automation Center (vCAC) can be utilized to

more easily configure, manage, monitor, and automate the network. It will utilize the northbound REST

API available via the NSX Manager, and the controller cluster is responsible for the intake of the respective

network configuration directives from the NSX Manager. Figure 8 below displays a diagram showing the

NSX component interaction.

Note here that NSX Manager achieves control plane security for communication to controllers and

vSphere ESXi hosts via SSL certificates. The NSX VDS switches and NSX edge devices register with the NSX

controller cluster using the NSX API; security is provided via SSL certificate. The NSX Manager generates

self-signed certificates for each of the ESXi hosts and controllers; these certificates are then pushed to the

respective ESXi hosts and controllers.

5.2 Broadcast, Unknown Unicast, and Multicast Traffic (BUM)

The VXLAN standard resolves broadcast, unknown unicast, and multicast (BUM) traffic via multicast

enabled physical network. NSX provides flexibility in how VXLAN replication is handled. It offers three

control plane modes for the handling of BUM traffic: unicast, hybrid, and multicast.
