Troubleshooting NSX Infrastructure

NSX preparation is a 4-step process.

1. Connect NSX Manager to vCenter Server. There is a one-to-one relationship between NSX Manager and vCenter Server.
   1. Register with vCenter Server.
2. Deploy NSX Controllers (Only required for logical switching, distributed routing, or VXLAN in unicast or hybrid mode. If you are only using distributed firewall (DFW), controllers are not required).
3. Host Preparation: Installs VIBs for VXLAN, DFW, and DLR on all hosts in the cluster. Configures the Rabbit MQ-based messaging infrastructure. Enables firewall. Notifies controllers that hosts are ready for NSX.
4. Configure IP pool settings and configure VXLAN: Creates a VTEP port group and VMKNICs on all hosts in the cluster. During this step, you can set the transport VLAN ID, teaming policy, and MTU.

For more information about installation and configuration of each step, refer to NSX Installation Guide and NSX Administration Guide.
