mrStackSelectPrimarySupervisorUnit
1.3.6.1.4.1.9.2.11.1.1.3
In a multi-unit FastHub stack with more than one Supervisor
management module installed, this object selects which
unit and hence, which Supervisor module, should have the
primary management role. The value specified is a unit
number that corresponds to an integer index into the
mrStackUnitTable.
Once a primary management unit has been chosen, the
remaining management modules, if any, will automatically
assume the standby role.
