Service:
The service selection determines the type of service running on the servers in the farm and
how the WebMux will check the server health status. The service type selection will create a
farm using the well-known port for that service type. If a port other than a well-known port
for TCP or UDP service is to be used, then choose one of the “Generic” selections and enter
the port number in the PORT NUMBER field. You do will not need to specify the port
number if the service protocol is on the list. The WebMux has level 7 protocol checks for the
known ports in the list. For Custom Defined TCP Service (custom health check), please
specify the URL for the CGI code in the Administration Setup screen.
CAUTION Once a farm is created, the port number cannot be changed. Like the IP
address, the farm must be deleted and a new one created in order to change farm settings.
Please choose “Generic TCP” and specify port number, if service is not listed below. If
multiple ports to be used, please also select “Generic TCP” and specify port number “0.”
