  16. Verify that the NSX-T Manager 3 appliance is added.

Configure the NSX-T Management VIP

The NSX-T Management layer includes three NSX-T Manager nodes. To support a single access point, assign a virtual IP Address (VIP) to the NSX-T Management layer. Once the VIP is assigned, any UI and API requests to NSX-T are redirected to the virtual IP address of the cluster, which is owned by the leader node. The leader node then routes the request forward to the other components of the appliance.

Using a VIP makes the NSX Management Cluster highly-available. If you need to scale, an alternative to the VIP is to provision a load balancer for the NSX-T Management Cluster. Provisioning a load balancer requires that NSX-T be fully installed and configured. VMware recommends that you configure the VIP now, then install a load balancer after NSX-T is installed and configured, if needed.

Complete the following instructions to create a VIP for the NSX Management Cluster. The IP address you use for the VIP must be part of the same subnet as the NSX-T Management nodes.

  1. In the NSX Management Console, navigate to System > Appliances.
  2. Click the Set Virtual IP button.
  3. Enter a Virtual IP address. For example, 10.173.62.47.
  4. Verify that the VIP is added.
  5. Access the NSX-T Management console using the VIP. For example, https://10.173.62.47/.

Enable the NSX-T Manager Interface

The NSX Management Console provides two user interfaces: Policy and Manager. TKGI requires the Manager interface for configuring networking and security objects. Do NOT use the Policy interface for TKGI objects.

  1. In the NSX-T Manager console, navigate to System > User Interface Settings.
  2. Click Edit.
  3. For the Toggle Visibility field, select Visible to all Users.
  4. For the Default Mode field, select Manager.
  5. Click Save.
  6. Refresh the NSX-T Manager Console and navigate to an area of the console that is not listed under System.
  7. In the upper-right area of the console, verify that the Manager option is enabled.

Add the NSX-T Manager License

If you do not add the proper NSX-T license, you will receive an error when you try to deploy an Edge Node VM.

  1. In the NSX-T Manager console, navigate to System > Licenses.
  2. Add the NSX Data Center Advanced (CPU) license.
  3. Verify that the license is added.

Generate and Register the NSX-T Management SSL Certificate and Private Key

An SSL certificate is automatically created for each NSX-T Manager. You must also generate a certificate for the NSX-T Manager VIP.

To generate a certificate for the NSX-T Manager VIP, see Generate and Register the NSX-T Management TLS Certificate and Private Key.


Create an IP Pool for TEP

Tunnel endpoints (TEPs) are the source and destination IP addresses used in the external IP header to identify the ESXi hosts that originate and end the NSX-T encapsulation of overlay frames. The TEP addresses do not need to be routable so you can use any random IP addressing scheme you want. For more information, see the NSX-T Data Center documentation.

  1. In the NSX-T Management Console, select the Manager interface (upper right).
  2. Navigate to Networking > IP Address Pool.
  3. Click Add.
  4. Enter a Name. For example, TEP-IP-POOL.
  5. Enter an IP range. For example, 192.23.213.1 - 192.23.213.10.
  6. Enter a CIDR address. For example, 192.23.213.0/24.
  7. Click Add.
  8. Verify that the pool is added.

Configure Transport Zones

See Configuring NSX-T Data Center v3.1 Transport Zones and Edge Node Switches for TKGI.

Configure vSphere Networking for ESXi Hosts

In this section, 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.

For more information, see the Release Notes for details about TKGI support for vSphere 7 VDS for NSX-T transport node traffic.

Create vSwitch Port-Groups for Edge Nodes

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-VTEP-PG: VLAN 3127

  • EDGE-UPLINK-PG: VLAN trunk (All (4095))

  • Log in to the vCenter Server.

  • Select the ESXi host in the MANAGEMENT-cluster.
  • Select Configure > Virtual switches.
  • Select Add Networking (upper right).
  • Select the option Virtual Machine Port Group for a Standard Switch and click Next.
  • Select the existing standard switch named vSwitch0 and click Next.
  • Enter a Network Label. For example, EDGE-VTEP-PG.
  • Enter a VLAN ID. For example, 3127.
  • Click Finish.
  • Verify that you see the newly created port group.
  • Select Add Networking (upper right).
  • Select the option Virtual Machine Port Group for a Standard Switch and click Next.
  • Select the existing standard switch named vSwitch0 and click Next.
  • Enter a Network Label. For example, EDGE-UPLINK-PG.
  • For the VLAN ID, select All (4095) from the drop-down.
  • Click Finish.
  • Verify that you see the newly created port group.

Set vSwitch0 with MTU at 9000

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.

  1. Select the Virtual Switch on each ESXi host in the MANAGEMENT-cluster, or each host in the vCenter cluster.
  2. Click Edit.
  3. For the MTU (bytes) setting, enter 9000.
  4. Click OK to complete the operation.

Deploy NSX-T Edge Nodes

In this section you deploy two NSX-T Edge Nodes.

NSX-T Edge Nodes provide the bridge between the virtual network environment implemented using NSX-T and the physical network. Edge Nodes for Tanzu Kubernetes Grid Integrated Edition run load balancers for TKGI API traffic, Kubernetes load balancer services, and ingress controllers. See Load Balancers in Tanzu Kubernetes Grid Integrated Edition for more information.

In NSX-T, a load balancer is deployed on the Edge Nodes as a virtual server. The following virtual servers are required for Tanzu Kubernetes Grid Integrated Edition:

  • 1 TCP Layer 4 virtual server for each Kubernetes service of type:LoadBalancer
  • 2 Layer 7 global virtual servers for Kubernetes pod ingress resources (HTTP and HTTPS)
  • 1 global virtual server for the TKGI API

The number of virtual servers that can be run depends on the size of the load balancer which depends on the size of the Edge Node. Tanzu Kubernetes Grid Integrated Edition supports the medium and large VM Edge Node form factor, as well as the bare metal Edge Node. The default size of the load balancer deployed by NSX-T for a Kubernetes cluster is small. The size of the load balancer can be customized using Network Profiles.

For this installation, we use the Large VM form factor for the Edge Node. See VMware Configuration Maximums for more information.

Deploy ESXi Host Transport Nodes Using VDS

Deploy each ESXi host in the COMPUTE-cluster as an ESXi host transport node (TN) in NSX-T. If you have not created a separate COMPUTE-cluster for ESXi hosts, deploy each ESXi host in the vSphere cluster as a host transport node in NSX-T.

  1. Go to System > Fabric > Nodes > Host Transport Nodes.

  2. Expand the Compute Manager and select the ESXi host in the COMPUTE-cluster, or each ESXi host in the vSphere cluster.

  3. Click Configure NSX.

  4. In the Host Details tab, enter a name. For example, 10.172.210.57.

  5. In the Configure NSX tab, configure the transport node as follows:

    • Type: VDS (do not select the N-VDS option)
    • Name: switch-overlay (you must use the same switch name that was configured for tz-overlay transport zone)
    • Transport Zone: tz-overlay
    • NIOC Profile: nsx-default-nioc-hostswitch-profile
    • Uplink Profile: nsx-esxi-uplink-hostswitch-profile
    • LLDP Profile: LLDP [Send Packet Disabled]
    • IP Assignment: Use IP Pool
    • IP Pool: TEP-IP-POOL
    • Teaming Policy Switch Mapping
      • Uplinks: uplink-1
      • Physical NICs: vmnic1

  6. Click Finish.

  7. Verify that the host TN is configured.

Verify TEP to TEP Connectivity

To avoid any overlay communication in the future due to MTU issue, test TEP to TEP connectivity and verify that it is working.

  1. SSH to edge-node-1 and get the local TEP IP address. For example, 192.23.213.1. Use the command get vteps to get the IP.

  2. SSH to edge-node-2 and get the local TEP IP address, ushc as 192.23.213.2. Use the command get vteps to get the IP.

  3. SSH to the ESXi host and get the TEP IP address. For example, 192.23.213.3. Use the command esxcfg-vmknic -l to get the IP. The interface will be vmk10 and the NetStack will be vxlan.

  4. From each ESXi transport node, test the connections to each NSX-T Edge Node, for example:

    # vmkping ++netstack=vxlan 192.23.213.1 -d -s 1572 -I vmk10: OK
# vmkping ++netstack=vxlan 192.23.213.2 -d -s 1572 -I vmk10: OK

    1. Test the connection from NSX-T Edge Node 1 and Edge Node 2 to ESXi TN:

Create NAT Rules

You need to create the following NAT rules on the Tier-0 router for the TKGI Management Plane VMs.

  • DNAT: 10.173.62.220 (for example) to access Ops Manager
  • DNAT: 10.173.62.221 (for example) to access Harbor

  • SNAT: 10.173.62.222 (for example) for all TKGI management plane VM traffic destined to the outside world

  • In the NSX Management console, navigate to Networking > NAT.

  • In the Logical Router field, select the T0-router you defined for TKGI.

  • Click Add.

  • Configure the Ops Manager DNAT rule as follows:

    • Priority: 1000
    • Action: DNAT
    • Protocol: Any Protocol
    • Destination IP: 10.173.62.220, for example
    • Translated IP: 10.1.1.2, for example

  • Click Add and verify.

  • Add a second DNAT rule for Harbor by repeating the same operation.

    • Priority: 1000
    • Action: DNAT
    • Protocol: Any Protocol
    • Destination IP: 10.173.62.221, for example
    • Translated IP: 10.1.1.6, for example

  • Verify the creation of the DNAT rules.

  • Create the SNAT rule for the management plane traffic as follows:

    • Priority: 9024
    • Action: SNAT
    • Protocol: Any Protocol
    • Source IP: 10.1.1.0/24, for example
    • Translated IP: 10.173.62.222, for example

  • Verify the creation of the SNAT rule.

Configure the NSX-T Password Interval (Optional)

The default NSX-T password expiration interval is 90 days. After this period, the NSX-T passwords will expire on all NSX-T Manager Nodes and all NSX-T Edge Nodes. To avoid this, you can extend or remove the password expiration interval, or change the password if needed.

Note: For existing Tanzu Kubernetes Grid Integrated Edition deployments, anytime the NSX-T password is changed you must update the BOSH and TKGI tiles with the new passwords. See Adding Infrastructure Password Changes to the Tanzu Kubernetes Grid Integrated Edition Tile for more information.

Update the NSX-T Manager Password and Password Interval

To update the NSX-T Manager password, perform the following actions on one of the NSX-T Manager nodes. The changes will be propagated to all NSX-T Manager nodes.

SSH into the NSX-T Manager Node

To manage user password expiration, you use the CLI on one of the NSX-T Manager nodes.

To access a NSX-T Manager node, from Unix hosts use the command ssh USERNAME@IP_ADDRESS_OF_NSX_MANAGER.

For example:

ssh [email protected]

On Windows, use PuTTY and provide the IP address for NSX-T Manager. Enter the user name and password that you defined during the installation of NSX-T.

Retrieve the Password Expiration Interval

To retrieve the password expiration interval, use the following command:

get user USERNAME password-expiration

For example:

NSX CLI (Manager, Policy, Controller 3.0.0.0.0.15946739). Press ? for cost or enter: help
nsx-mgr-1> get user admin password-expiration
Password expires 90 days after last change

Update the Admin Password

To update the user password, use the following command:

set user USERNAME password NEW-PASSWORD old-password OLD-PASSWORD.

For example:

set user admin password my-new-pwd old-password my-old-pwd

Set the Admin Password Expiration Interval

To set the password expiration interval, use the following command:

set user USERNAME password-expiration PASSWORD-EXPIRATION.

For example, the following command sets the password expiration interval to 120 days:

set user admin password-expiration 120

Remove the Admin Password Expiration Interval

To remove password expiration, use the following command:

clear user USERNAME password-expiration.

For example:

clear user admin password-expiration

To verify:

nsx-mgr-1> clear user admin password-expiration
nsx-mgr-1> get user admin password-expiration
Password expiration not configured for this user

Update the Password for NSX-T Edge Nodes

To update the NSX-T Edge Node password, perform the following actions on each NSX-T Edge Node.

Note: Unlike the NSX-T Manager nodes, you must update the password or password interval on each Edge Node.

Enable SSH

SSH on the Edge Node is deactivated by default. You have to enable SSH on the Edge Node using the Console from vSphere.

start service ssh
set service ssh start-on-boot

SSH to the NSX-T Edge Node

For example:

ssh [email protected]

Get the Password Expiration Interval for the Edge Node

For example:

nsx-edge> get user admin password-expiration
Password expires 90 days after last change

Update the User Password for the Edge Node

For example:

nsx-edge> set user admin password my-new-pwd old-password my-old-pwd

Set the Password Expiration Interval

For example, the following command sets the password expiration interval to 120 days:

nsx-edge> set user admin password-expiration 120

Remove the Password Expiration Interval

For example:

NSX CLI (Edge 3.0.0.0.0.15946012). Press ? for command list or enter: help
nsx-edge-2> get user admin password-expiration
Password expires 90 days after last change. Current password will expire in 7 days.

nsx-edge-2> clear user admin password-expiration
nsx-edge-2> get user admin password-expiration
Password expiration not configured for this user

Next Steps

Once you have completed the installation of NSX-T v3.0, return to the TKGI installation workflow and proceed with the next phase of the process. See Install Tanzu Kubernetes Grid Integrated Edition on vSphere with NSX-T Using Ops Manager.
