Specifies whether VTAM® uses the basic or enhanced security protocol when performing session-level LU-LU verification. SECLVL specifies the type of verification; the related VERIFY operand specifies whether VTAM performs verification.
This operand is valid only when APPC=YES and session-level
LU-LU verification is used. (VERIFY=OPTIONAL or VERIFY=REQUIRED must
be coded on this application program major node. If you code VERIFY=NONE
or let it default, a parameter conflict results.)
- SECLVL=ADAPT
- Specifies that either the enhanced or the basic protocol is used for sessions that use session-level LU-LU verification. VTAM attempts to use the enhanced protocol but accepts the use of the basic protocol if a partner LU does not support the enhanced protocol.
- SECLVL=LEVEL1
- Specifies that the basic protocol is used for sessions that use session-level LU-LU verification. If a partner LU does not support the basic protocol, VTAM rejects the session and issues a sense code.
- SECLVL=LEVEL2
- Specifies that VTAM uses only the enhanced protocol for sessions that use session-level LU-LU verification. If a partner LU does not support the enhanced protocol, VTAM rejects the session and issues a sense code.
