NOF Indications
DOWNSTREAM_LU_INDICATION
Chapter 61124
DOWNSTREAM_LU_INDICATION
This indication is generated when either the LU-SSCP session or the
PLU-SLU session between the downstream LU and the host changes
state between active and inactive. When one of these sessions becomes
inactive, the indication also includes session statistics for that session.
