ASMP (Avocent Secure Management Protocol)
A protocol used to securely configure managed appliance settings. This TCP based protocol uses an
SSL encrypted communications link. AMSP uses TCP port 3211.
NOTE: Port 3211 is non-configurable.
Auditing
The process of tracking DSView user activities by recording selected types of events in the audit
log of the DSView Server.
Authentication Server
An authentication server is a network device that provides authentication services.
Authentication
The validation of DSView user log in information. Authentication is used to enforce selective
permission to access resources or to perform an operation.
Authorization
The process of granting or denying access to a resource. Most computer security systems are based
on a two-step process. The first stage is authentication, which ensures that a user is who they claim
to be. The second stage is authorization, which allows the user access to various resources based on
the user's identity.
Avocent Video Session Protocol (AVSP)
A protocol used to transfer keyboard, video and mouse information between an DSR switch and a
remote Video Viewer. AVSP operates over SSL encrypted TCP links. TCP/IP ports 8192 and 2068
are used by default, but may be configured to different port numbers.
Browser Session
A type of target device session in which the target device contains a web server. The DSView
Client connects directly to the target device using a web browser. No DSR switches or CPS
appliances are used for Browser sessions.
Cascade Device
A device that connects between a DSR switch or CPS appliance and a target device, or connects to
a DSR switch or CPS appliance and is not in itself a target device. Examples of cascade devices are
a cascade switch and an SPC power control device.
