Configure NSX-T Passwords

Page last updated:

This topic provides instructions for configure NSX-T passwords after you have installed NSX-T for TKGI.

Prerequisites

Before completing this section, make sure you have completed the following sections:

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

SSH into the NSX Manager Node

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

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

For example:

ssh admin@10.196.188.22

On Windows, use Putty and provide the IP address for NSX 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 Edge Nodes

To update the NSX Edge Node password, perform the following actions on each NSX 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 disabled 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 Edge Node

For example:

ssh admin@10.196.188.25

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 Step

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.
