This topic describes how to configure vSphere Networking for ESXi Hosts for VMware Tanzu Kubernetes Grid Integrated Edition (TKGI).
Before completing this section, make sure you have completed the following sections:
In this section of the NSX-T installation for TKGI, you configure the vSphere networking and port groups for ESXi hosts (the vSwitch). If you have created separate vSphere clusters for Management and Compute, perform this operation on each ESXi host in the Management cluster. If you have not created separate vSphere clusters, perform this operation on each ESXi host in the cluster.
The following instructions describe how to configure a vSphere Virtual Standard vSwitch (VSS). For production environments, it is recommended that you configure a Virtual Distributed vSwitch (VDS). You configure the VDS from the vCenter Networking tab and then add the ESXi hosts to the VDS. The configuration settings for the VDS are similar to the VSS configuration described below. For instructions on configuring the VDS, see Create a vSphere Distributed Switch in the vSphere 7 documentation.
Refer to the Release Notes for details on TKGI support for vSphere 7 VDS for NSX-T transport node traffic.
Create vSwitch Port-Groups for the Edge Nodes on the ESXi hosts in the MANAGEMENT-cluster.
For each ESXi host in the MANAGEMENT-cluster, create the following vSwitch Port Groups:
EDGE-UPLINK-PG: VLAN trunk (All (4095))
Log in to the vCenter Server.
vSwitch0
and click Next. EDGE-VTEP-PG
.3127
. vSwitch0
and click Next.EDGE-UPLINK-PG
.All (4095)
from the drop-down. For each ESXi host in the MANAGEMENT-cluster, or each ESXi host in the vCenter cluster if you have not created separate Management and Compute clusters, you must enable the virtual switch with jumbo MTU, that is, set vSwitch0 with MTU=9000. If you do not do this, network overlay traffic will jam. The TEP interface for the NSX-T Edge Nodes must be connected to a port group that supports > 1600 bytes. The default is 1500.
