-i Defines an interface identifier to be shown (optional).
            Only one interface can be shown in a single operation.
            If specified, only elements containing this interface
            identifier are shown.  The -i option can be qualified by
            the -v option. The value has the following form:

            interface-uuid,major-version.minor-version

            The UUID is a hexadecimal string and the version numbers
            are decimal strings, for example:

            -i EC1EEB60-5943-11C9-A309-08002B102989,1.1

            Leading zeros in version numbers are ignored.

         -o Defines an object to be shown (optional).  Each show
            mapping command accepts up to 32 -o options.

            The UUID is a hexadecimal string, for example:

            -o 3C6B8F60-5945-11C9-A236-08002B102989

         -v Indicates how a specified interface version is used
            (optional).  If used without the -i option, the -v option
            is ignored.  The possible combinations of versions for
            the -v option and their actions are as follows:

            ________________________________________________
            Versions     Action
            ________________________________________________
            all          The interface version is ignored.

            exact        Both the major and minor versions
                         must match the specified versions.

            compatible   The major version must match the
                         specified version, and the minor
                         version must be greater than or
                         equal to the specified version.

            major_only   The major version must match the
                         specified version; the minor
                         version is ignored.

            upto         The major and minor versions must
                         be less than or equal to those
                         specified.
            ________________________________________________

            If the -v option is absent, the command shows compatible
            version numbers.
