Federation Requirements

To support Federation, your environment must meet various requirements, including round-trip time, software versions, and ports.

• There must be a maximum round-trip time of 150 ms between the following nodes:
  • Global Manager and Local Manager.
  • Local Manager and remote Local Manager.
• The Global Manager and Local Manager appliances must all have NSX-T Data Center 3.0.0 or 3.0.1 installed. All appliances in a Federation environment must have the same version installed.
• The required ports must be open to allow communication between the Global Manager and Local Managers. See VMware Ports and Protocols at https://ports.vmware.com/home/NSX-T-Data-Center.
• There must be connectivity without NAT between the following nodes:
  • Global Manager and Local Manager.
  • Local Manager and remote Local Manager.
  • Edge node RTEP and remote Edge node RTEP.
• Global Manager supports only Policy Mode. Federation does not support Manager Mode. See NSX Manager for more information.

A Federation environment has the following configuration maximums:

• For most configurations, the Local Manager cluster has the same configuration maximums as an NSX Manager cluster. Go to VMware Configuration Maximums tool and select NSX-T Data Center.

  Select the Federation category for NSX-T Data Center in the VMware Configuration Maximums tool for exceptions and other Federation-specific values.

• For a given location, the following configurations contribute to the configuration maximum:

  • Objects that were created on the Local Manager.
  • Objects that were created on the Global Manager and include the location in its span.

  You can view the capacity and usage on each Local Manager. See View the Usage and Capacity of Categories of Objects in the NSX-T Data Center Administration Guide.
