The VERIFY operand specifies whether the VTAM® program performs session-level LU-LU verification during activation of LU-LU 6.2 sessions.

• VERIFY=NONE specifies that no verification of the partner LU’s identity takes place during session activation.
• VERIFY=OPTIONAL specifies that identity verification is performed for certain partner LUs during session activation. Determination for which partner LUs the LU-LU verification is performed depends on whether there is a password defined for the LU-LU pair in the installed security manager product.
• VERIFY=REQUIRED specifies that VTAM verifies the identity of all partner LUs during activation of sessions between LU 6.2 applications. Every partner LU must have a LU-LU password defined. Any partner LUs that do not have a LU-LU password defined cannot establish LU 6.2 sessions with this application program.

The example that follows illustrates the use of the VERIFY operand.
