PREEMPTION
LEVEL
DESCRIPTION
4
The default level for a new local user of a KVM switch or
serial console appliance.
3
The default level for the Avocent® Universal
Management Gateway Appliance .
2
The default level for the user administrator user group.
1
Default for new users. The default for the Factory user
account.
The preemption levels may be used in the following ways:
•
User preemption level - This is the preemption level assigned to a user by an administrator. If this value is
larger than the highest preemption level of the user group to which the user belongs, the value will be used as
the effective user preemption level.
•
Group preemption level - This is the preemption level assigned to user groups to which the user belongs. If the
user is assigned to multiple user groups with different preemption levels, this will be the preemption level of
the user group with the highest level. For example, if a user belongs to the appliance administrators (level 6)
and users (level 1) user groups, this value will be defined as 6. If this value is larger than the highest preemption
level of the user, the value will be used as the effective user preemption level.
An appliance administrator or power user may also specify a local user interface preemption level that is applied to users
accessing target devices through the local interface.
