The group containing the repeater port to which this switch link is attached. For internal switches, this object may not be modified by a network management operation. For external switches, an instance of this object will be created with the value of zero. It must be modified to a non-zero value corresponding to a known repeater group index before the instance of the hpicfGRpSwitchStatus object associated with this switch can be set to 'active'.

An instance of this object may not be modified if the instance of the hpicfGRpSwitchStatus object associated with this switch would be equal to 'active' both before and after the modification attempt.
