NSX Manager provides a graphical user interface (GUI) and REST APIs for creating, configuring, and monitoring NSX-T components such as logical switches, logical routers, and firewalls. NSX Manager provides a system view and is the management component of NSX-T.
NSX Manager is supported on vSphere ESXi or KVM. You can install only one instance of NSX Manager. You can use vSphere's high availability (HA) feature to ensure the availability of NSX Manager. On ESXi, it is recommended that the NSX Manager appliance be installed on shared storage. vSphere HA requires shared storage, so that the NSX Manager appliance can be restarted on another host if the original host fails.
NSX Manager supports the following deployments methods:
NSX Manager must have a static IP address. You cannot change the IP address after installation.
NSX-T appliances have the following password complexity requirements:
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
The installation succeeds even if the password does not meet the complexity requirements. If you do not specify a password of sufficient complexity for user admin during deployment, you must log in as admin after deployment and respond to the prompt to change the password. If the user root also does not have a password of sufficient complexity, change the password with the following command while logged in as admin:
set user root password <password>
On a manager fresh install, reboot, or after an admin password change when prompted on first login, it can take minutes for the manager to start up.
The core services on the appliance does 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.
When installing NSX Manager, choose a hostname that does not contain underscores. If you specify a hostname that contains an underscore, after deployment the appliance will have a default hostname such as nsx-manager.
The NSX component virtual machine installations include VMware Tools. Removal or upgrade of VMware Tools is not supported for NSX appliances.
