Virtual Server Service Configuration
Use this menu to configure services assigned to a virtual server based on the selected application.
Each virtual server can be configured to support up to eight services, limited to a total of 1023 services per Alteon. Using this option, the following well-known TCP/UDP applications ports can be specified:
Notes
*For all applications without a well-known port, you can select Basic-SLB as the application.
*Alteon automatically identifies well-known ports.
*The service number specified on Alteon must match the service specified on the server.

Only relevant parameters for the application you specify appear in the service menu.
Each application has its own service configuration menu. The first menu example displays the Basic-SLB service configuration menu and includes commands common to all services. The subsequent menu examples are application-specific and the command descriptions are only for those commands that are specific to that application. For all common commands, refer to the Basic-SLB configuration menu.
Note: Once a service is configured for a specific application type/port, all following commands for the service must also be specified for the same application type/port. Otherwise an error message will be shown.
The following is the list of the application-specific menus that are described in this section:
