        Each row in the table represents a Group for the defined MEP. This 
        table uses four indices. The first three indices are the indices of 
        the Maintenance Domain, MaNet, and MEP tables. The fourth index is the 
        specific Group on the selected MEP. A Group is created on an existing MEP 
        using extremeCfmGroupIndex in the row creation.

        Only few objects are writable in this table. 

        The writable objects in this table need to be persistent upon reboot 
        or restart of a device.

        is never reused for other groups on the same MEP while this
        group is active.  The index value keeps increasing until it
        wraps to 0. This is to facilitate access control based
        on a fixed index for an EMS, since the index is not reused.
