Configuring a Session Management (TD/SMP) Terminal

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.

Simultaneous data exchange with multiple service sessions.

Management of terminal sessions using terminal commands.

Restrictions on some access server commands (see the table in the Local Mode Command Restrictions During Session Management section in this chapter).
