User Preemption Levels
The preemption level of a DSView user determines whether or not the they can interrupt or
disconnect another DSView user’s Serial or Video (KVM) Session with a target device.
DSView Administrators and User Administrators may specify the preemption level for DSView
user accounts or user-defined user groups when an account or group is created. The preemption
level for DSView users may be changed later by using the User Preemption Level window, or for
user-defined groups by using the User Group Properties window. See Changing the preemption
level of DSView users on page 235 or Viewing and modifying user group members on page 339 for
more information.
By default, the preemption level used by the DSView software (the effective user preemption level)
is the highest level of all of the user groups to which the DSView user belongs. Preemption levels
range from 1-4, with 4 having the highest preemption level. For example, a user or a user group
with a preemption level of 4 may preempt other level 4 users or user groups, as well as those with a
level 1, 2 or 3 setting.
The preemption levels and a description of each appear in Table 1.7:
There are three preemption levels:
User preemption level - The preemption level that may be assigned to a DSView user by a
DSView Administrator or User Administrator. If this value is larger than the highest preemp-
tion level of the user group to which the DSView user belongs, the value will be used as the
effective user preemption level.
Group preemption level - The preemption level that is assigned to user groups to which the
DSView user belongs. If the DSView 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 DSView user belongs to the DSView Administrators (level 3) and Auditors
(level 1) user groups, this value will be defined as 3. If this value is larger than the highest pre-
emption level of the DSView user, the value will be used as the effective user
preemption level.
