• Single-direction-The target authenticates the identity of the initiator with the user-provided CHAP secret. To enable single-direction CHAP, you must enable CHAP for a specific initiator record on the MPX200 and enter a corresponding CHAP secret from the iSCSI host. • Bidirectional-The initiator and target authenticate each other's identity by using the user-provided CHAP secrets. To enable bidirectional CHAP for a discovery session, you must provide a CHAP secret for the initiator and for the iSCSI port for which you are performing discovery. To enable bidirectional CHAP for a normal session, you must provide a CHAP secret for the initiator and for the iSCSI-presented target that you want to log in to. • Single-direction CHAP during discovery session and during normal session • Single-direction CHAP during discovery session and bidirectional CHAP during normal session • Bidirectional CHAP during discovery session and single-direction CHAP during normal session • Bidirectional CHAP during discovery session and during normal session Enabling single-direction CHAP during discovery session and normal session Table 12 lists the settings you use to enable single-direction CHAP during a discovery session and normal session.
