LU 6.2 session-level security
This function provides an optional security protocol for verifying the identity of a partner LU when LU-LU sessions are established.
APPC=YES is required for LU 6.2 session-level security.
During activation of LU 6.2 sessions involving control points, the VERIFYCP start option specifies whether VTAM® performs session-level LU-LU verification. See the VERIFYCP start option in the Network node start option list for more information.
