NSX Manager provides a graphical user interface (GUI) and REST APIs for creating, configuring, and monitoring NSX-T Data Center components such as logical switches, logical routers, and firewalls.

NSX Manager provides a system view and is the management component of NSX-T Data Center.

An NSX-T Data Center deployment can have only one instance of NSX Manager. If NSX Manager is deployed on an ESXi host, you can use the vSphere high availability (HA) feature to ensure the availability of NSX Manager.

Table 1. NSX Manager Deployment, Platform, and Installation Requirements



Supported deployment methods


  • QCOW2

Supported platforms

See System Requirements.

On ESXi, it is recommended that the NSX Manager appliance be installed on shared storage. vSphere HA requires shared storage so that VMs can be restarted on another host if the original host fails.

IP address

An NSX Manager must have a static IP address. You cannot change the IP address after installation.

NSX-T Data Center appliance password

  • At least eight characters

  • At least one lower-case letter

  • At least one upper-case letter

  • At least one digit

  • At least one special character

  • At least five different characters

  • No dictionary words

  • No palindromes


When installing NSX Manager, specify a hostname that does not contain invalid characters such as an underscore. If the hostname contains any invalid character, after deployment the hostname will be set to nsx-manager. For more information about hostname restrictions, see https://tools.ietf.org/html/rfc952 and https://tools.ietf.org/html/rfc1123.

VMware Tools

The NSX Manager VM running on ESXi has VMTools installed. Do not remove or upgrade VMTools.


  • Verify that the system requirements are met. See System Requirements.

  • Verify that the required ports are open. See Ports and Protocols.

  • If you do not already have one, create the target VM port group network. It is recommended to place NSX-T Data Center appliances on a management VM network.

    If you have multiple management networks, you can add static routes to the other networks from the NSX-T Data Center appliance.

  • Plan your IPv4 IP address scheme. In this release of NSX-T Data Center, IPv6 is not supported.

OVF Privileges

Verify that you have adequate privileges to deploy an OVF template on the ESXi host.

A management tool that can deploy OVF templates, such as vCenter Server or the vSphere Client. The OVF deployment tool must support configuration options to allow for manual configuration.

OVF tool version must be 4.0 or later.

Client Plug-in

The Client Integration Plug-in must be installed.


On an NSX Manager fresh install, reboot, or after an admin password change when prompted on first login, it might take several minutes for the NSX Manager to start.

NSX Manager Installation Scenarios


When you install NSX Manager from an OVA or OVF file, either from vSphere Web Client or the command line, OVA/OVF property values such as user names, passwords, or IP addresses are not validated before the VM is powered on.

  • If you specify a user name for the admin or audit user, the name must be unique. If you specify the same name, it is ignored and the default names (admin and audit) is used.

  • If the password for the admin user does not meet the complexity requirements, you must log in to NSX Manager through SSH or at the console as the admin user. You are prompted to change the password.

  • If the password for the audit user does not meet the complexity requirements, the user account is disabled. To enable the account, log in to NSX Manager through SSH or at the console as the admin user and run the command set user audit to set the audit user's password (the current password is an empty string).

  • If the password for the root user does not meet the complexity requirements, you must log in to NSX Manager through SSH or at the console as root with the password vmware. You are prompted to change the password.


Changes made to the NSX-T Data Center while logged in with the root user credentials might cause system failure and potentially impact your network. You can only make changes using the root user credentials with the guidance of VMware Support team.


The core services on the appliance do not start until a password with sufficient complexity is set.

After you deploy NSX Manager from an OVA file, you cannot change the VM's IP settings by powering off the VM and modifying the OVA settings from vCenter Server.
