Administrative Management Preference

The "Administrative Management Preference" indicates the preference given to this unit over another units
in a stack by an administrator when the management unit fails. The default value is 1. A value of 0 means
the unit cannot become a management unit.
This field indicates the administrative management preference value assigned to the switch. This
preference value indicates how likely the switch is to be chosen as the management unit. The attribute for
"Admin Management Preferences" can be changed through the

Unsetting Management Preference

There is no CLI command to set the management preference back to "unassigned". The management
preference information is stored locally on each unit, and can be erased using the boot menu option that
deletes all configuration files including the unit number.

Management Preference and MAC Address

The role of each switch in a stack as either manager or member can be changed by setting the management
preference and MAC address. Management preference is considered before the MAC address. The higher
the management preference value is makes it more likely for that switch to become manager. Likewise, the
higher the MAC address value is makes it more likely for that switch to become manager.
The preference decision is made only when the current manager fails and a new manager needs to be
selected, or when a stack of units is powered up with none of the units previously holding the management
role. If two managers are connected together, then management preference has no effect.

Upgrading Software in a Stack

With all versions of SFTOS, using the
switch automatically propagates that software to all stack members. You would then use the
command to reboot all switches in the stack, which would include installing that new software.
However, in SFTOS 2.5.1, the
command to download software while running 2.5.1, you specify in which of two bins (
), the new software will be stored:

Previous to SFTOS 2.5.1, the syntax is:
