VMware NSX-T does not support VXLAN!

NSX-T Segments#

a VM is connected to a segment.

  • is a layer-2 domain.
  • invokes a transport zone.
  • once the transport zone configured, you can no longer edit it later.
  • VLAN-based segments are equivalent to VLAN IDs
  • VLAN-based segments are not permitted to connect to Tier-0 or Tier-1 gateways.

require VLAN transport zones. A single Edge Uplink segment can be used more than once.

Tier-1 Gateways#

are always in active-standby HA mode. Invoke an edge cluster only if you want to use stateful services on this Tier-1 gateway.

Edge Cluster#

required, because it is not permitted to use a single edge transport node. == {edge transport nodes}

Transport Nodes#

a host transport node comes up only if at least one VM or container running on the associated [[Overlay Networks|overlay network]]is up.

Types of Transport Node Profiles#

VDS#

recommended instead of N-VDS. upgrade your ESXi hosts to v7 first, then configure the Tranport Node Profile.

N-VDS#

will be deprecated by VMware.

Cluster virtual IP#

is assigned to one management node at a time. If the node fails, the IP is allocated to the next management node.

Tanzu Basic#

VMware Tanzu Basic allows to embed Tanzu into the control plane of vSphere, or to deploy a Kubernetes management cluster on vSphere 6.7 or vSphere 7. That way, we can manage VMs and containers from vSphere.
