Configuring a virtual server
A virtual server is a virtual service provided by the LB device to determine whether to perform load balancing for packets received on the LB device. Only the packets that match a virtual server are load balanced.
The virtual server types supported by server load balancing include fast HTTP, HTTP, IP, RADIUS, TCP, and UDP. For the LB device to distribute packets correctly, follow these restrictions and guidelines:
Do not specify the same VSIP and port number for the virtual servers of the fast HTTP, HTTP, IP, RADIUS, and TCP types.
Do not use fast HTTP virtual servers together with the TCP client verification feature. For more information about the TCP client verification feature, see Security Configuration Guide.
