127 Using the Viewer
When you attempt to open a Video session with a device that is already being
viewed by another user, you are notified that the device is already being
viewed. Depending on the configuration of sharing settings, you may be
offered the option to share or preempt the video session. You may also be
offered the option to open a stealth Video session.
NOTE: Stealth video sessions are passive Video sessions, where the primary user
is not aware of the presence of the secondary user. The ability to open a stealth
video session is governed by the privilege of the user. If a user can preempt another
user, they can also open a Stealth Video session.
Access to the device is governed by the nature of the current user’s
connection to the device. There are two types of Video session users: a
Primary user and up to 11 simultaneous Secondary users (a single 2161DS-2
or 4161DS appliance supports up to 12 simultaneous sessions across all
attached servers). Only the Primary user can accept or reject preemption
requests for all users sharing a connection. The Primary user also maintains
control of video parameters and the display resolution of the Video session.
Secondary users may be either Active users who have the ability to input
mouse and keyboard data, or Passive users who may not input mouse and
keyboard data.
If Automatic Sharing is enabled on the Remote Console Switch, Secondary
Users do not need the permission of the Primary User to join the session.
If a Primary user leaves the session then the oldest Secondary user with Active
user privileges will become the Primary user. If there are no Secondary users
with Active user privileges sharing the session when the Primary user leaves
the session, then the session will be closed.
For more information about configuring connection sharing, see "Viewing and
Configuring Remote Console Switch Parameters" on page 141.
Exclusive Mode
Exclusive Mode allows you to have exclusive control of a Video session.
When in Exclusive Mode, no other user can share the session (except in
Stealth mode). If other users are sharing the session when you select
Exclusive Mode, you are warned that selecting Exclusive Mode will cause the
other users to become disconnected from the session.
