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.

Table 4.2: User and User Group Preemption Levels

Preemption Level Description

The default preemption level for a new local user of a KVM switch or serial console appliance.

The default preemption level for the DSView 3 software administrator and appliance administrator user groups.

The default preemption level for the user administrator user group.

The default preemption level for the users and auditors groups.

The preemption levels may be used in the following ways:

•User preemption level - This is the preemption level assigned to a user by a DSView 3 software administrator or user 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 administrators (level 3) and auditors (level 1) user groups, this value will be defined as 3. If this value is larger than the highest preemption level of the user, the value will be used as the effective user preemption level.

•Effective user preemption level - This is the largest value between the user and group preemption level, and is the actual preemption level that will be recognized by the DSView 3 software when the user attempts to preempt another user’s session. For example, if user belongs to the auditors group (level 1) but is assigned a user preemption level of 4, the user will have an effective user preemption level of 4. Although a member of the auditors group, this user would also be able to preempt the session of a user belonging to the administrators or appliance administrators user groups.

An administrator or user administrator may also specify an OSCAR graphical user interface preemption level that is applied to users accessing target devices through the OSCAR interface. See KVM Switch and Cascade Switch Settings on page 154.
