Transport zones and transport nodes are important concepts in NSX-T Data Center. Create Transport Zones Transport zones dictate which hosts and, therefore, which VMs can participate in the use of a particular network. A transport zone does this by limiting the hosts that can "see" a logical switch—and, therefore, which VMs can be attached to the logical switch. A transport zone can span one or more host clusters. Create an IP Pool for Tunnel Endpoint IP AddressesYou can use an IP pool for the tunnel endpoints. Tunnel endpoints are the source and destination IP addresses used in the external IP header to identify the hypervisor hosts originating and end the NSX-T Data Center encapsulation of overlay frames. You can also use either DHCP or manually configured IP pools for tunnel endpoint IP addresses. Enhanced Data PathEnhanced data path is a networking stack mode, which when configured provides superior network performance. It is primarily targeted for NFV workloads, which offer performance benefits leverging DPDK capability. Configuring ProfilesProfiles allow you to consistently configure identical capabilities for network adapters across multiple hosts or nodes. Create a Standalone Host or Bare Metal Server Transport NodeYou must first add your ESXi host, KVM host, or bare metal server to the NSX-T Data Center fabric and then configure the transport node. Manual Installation of NSX-T Data Center Kernel ModulesAs an alternative to using the NSX-T Data Center Fabric > Nodes > Hosts > Add UI or the POST /api/v1/fabric/nodes API, you can install NSX-T Data Center kernel modules manually from the hypervisor command line. Fully Collapsed vSphere Cluster NSX-T DeploymentConfigure NSX Manager, host transport nodes to run workload VMs, and NSX Edge VMs on a single cluster. Each host in the cluster provides two physical NICs that are configured for NSX-T.
