Configuring and Managing Interactive Devices
Configuring a Session Management (TD/SMP)
Terminal
Introduction
The MULTISESSION characteristic allows a session management terminal using
the terminal device/session management protocol (TD/SMP) to manage each
terminal session at the terminal itself, not at the access server. A terminal session
is a single session on an access server port that is operating under session
management control.
Session management terminals can have more than one terminal session with the
access server, but each terminal session can have one service session. A service
session is a session between a network resource and the terminal session.
With session management terminals, TD/SMP maintains the context of a service
session when the user switches to another terminal session. Session data from a
service node continues even though the service session is currently inactive. You
can visualize a session management terminal as two or more standard terminals
using the same physical access server port. For terminals that do not implement
TD/SMP, the access server suspends service session data until the user resumes
the session.
How to Configure
Configure the session management terminal for a LAT session as described in the
Configuring an Interactive Device for LAT Sessions section in this chapter.
Configure a Telnet session as described in the Configuring an Interactive Device
for Telnet Sessions section in this chapter. In addition you enable
MULTISESSIONs on the port, as follows:
Local> CHANGE PORT 2 MULTISESSIONS ENABLED
Benefits and Restrictions Summary
The following is a summary of the benefits and restrictions for session
management terminals:
• Context preservation for terminal sessions and their corresponding service
sessions.
• Multiple local modes (one for each terminal session) to manage service
sessions and port characteristics.
