        description:
            - Specifies the virtual service acting as virtual hosting (sni) parent.

        description:
            - Virtual routing context that the virtual service is bound to.
            - This is used to provide the isolation of the set of networks the application is attached to.
            - It is a reference to an object of type vrfcontext.

        description:
            - The quality of service weight to assign to traffic transmitted from this virtual service.
            - A higher weight will prioritize traffic versus other virtual services sharing the same service engines.
