The NSX Edge load balancer enables network traffic to follow multiple paths to a specific destination. It distributes incoming service requests evenly among multiple servers in such a way that the load distribution is transparent to users. There are two types of load balancing services to configure in NSX, a one-armed mode, also known as a proxy mode, or the Inline mode, otherwise known as the transparent mode. For more information, refer to NSX Administration Guide.

Prior to beginning troubleshooting and configuration verification, get an accurate description of the error, create a topology map in relation to the client, virtual server and backend server, and understand the application requirements. For example a client cannot connect, is different than random session errors after connection. While troubleshooting load balancer, always starts by verifying connectivity error.
