To create an application profile that balances either TCP or UDP traffic type, specify the name and the type of persistence in the profile.


  1. Log in to the vSphere Web Client.
  2. Click Networking & Security > NSX Edges.
  3. Double-click an NSX Edge.
  4. Click Manage > Load Balancer > Application Profiles.
  5. Click Add.
    The New Application Profile window opens.
  6. Specify the application profile parameters.
    1. Select the type of profile (TCP or UDP).
    2. Enter a name for the application profile.
    3. Select a type of persistence.
      Persistence tracks and stores session data, such as the specific pool member that serviced a client request. With persistence, client requests are directed to the same pool member throughout the life of a session or during subsequent sessions.
      Persistence Description
      Source IP

      This persistence type tracks sessions based on the source IP address.

      When a client requests a connection to a virtual server that supports a source IP address persistence, the load balancer checks whether that client was previously connected. If yes, the load balancer returns the client to the same pool member.


      This persistence type maintains persistent sessions between Windows clients and servers that are running the Microsoft Remote Desktop Protocol (RDP) service.

      For example, you can enable the MSRDP persistence to create a load balancing pool that consists of members running Windows Server 2003 or Windows Server 2008. In this scenario, all members belong to a Windows cluster and participate in a Windows session directory.

      This persistence type is available only for a TCP application profile.
