ZVSN1
specifies whether the application using this PROFILE can operate over a
session protocol version 1 connection. If this field is set to ZSPI-VAL-TRUE,
the application can operate over protocol version 1; if it is set to ZSPI-VAL-
FALSE, the application cannot operate over protocol version 1.
ZVSN2
specifies whether the application using this PROFILE can operate over a
session protocol version 2 connection. If this field is set to ZSPI-VAL-TRUE,
the application can operate over protocol version 2; if it is set to ZSPI-VAL-
FALSE, the application cannot operate over protocol version 2.
The version is negotiated between the session entities at each end of the
connection. If an application using OSI/AS initiates the connection, OSI/AS
will propose either or both versions, depending on the settings of ZVSN1 and
ZVSN2. If an application using OSI/AS is the responder, OSI/AS will accept
the connection if there is a match between a proposed version and the settings
of ZVSN1 and ZVSN2. If both versions are proposed and both fields are set to
ZSPI-VAL-TRUE, OSI/AS will establish a protocol version 2 connection.
ZSPI-TKN-RETCODE, ZSPI-TKN-ERRLIST, ZSPI-TKN-ENDLIST, and ZSPI-
TKN-CONTEXT
are described in the Distributed Systems Management (DSM) Programming Manual.
Operational Notes
The following conditions, based on settings of fields in the Layer 3 SERVICE and
PROFILE tokens, determine whether the full subset of the OSI internet protocol (IP) is
enabled:
For X25AM lines, the full subset of the IP is enabled if ZIP-X25-SNDCF is set to
ZSPI-VAL-TRUE; it is disabled if ZIP-X25-SNDCF is set to ZSPI-VAL-FALSE. The
ZIP-NULL-LAYER and ZESIS-ENABLE fields are ignored.
For TLAM lines, these conditions apply:
If ZESIS-ENABLE is set to ZSPI-VAL-TRUE, the full subset of the IP is enabled
and the ZIP-NULL LAYER field is ignored.
If ZESIS-ENABLE is set to ZSPI-VAL-FALSE, the full subset of the IP is
enabled if ZIP-NULL-LAYER is set to ZSPI-VAL-FALSE, and is disabled if
ZIP-NULL-LAYER is set to ZSPI-VAL-TRUE.
The ZIP-X25-SNDCF field is ignored for TLAM lines.
ZIP-NULL-LAYER and ZX25-SNDCF can be set in the Layer 3 SERVICE and in
individual Layer 3 PROFILEs. ZESIS-ENABLE can be set only in the Layer 3
SERVICE.
