Chapter VII. iSCSI PDU Offload Target
Chelsio T5/T4 Unified Wire For Linux Page 136
4.11.2. iscsi_auth_order
Options: “ACL” or “CHAP”, defaults to “CHAP”
On an iSCSI target when ACL_Enable is set to Yes, iscsi_auth_order decides whether to
perform CHAP first then ACL or perform ACL then CHAP.
ACL: When setting iscsi_auth_order=ACL, initiator authorization will be performed at the
start of the login phase for an iSCSI normal session: upon receiving the first
iscsi_login_request, the target will check its ACL. If this iSCSI connection does not match
any ACL provisioned, the login attempt will be terminated.
CHAP: When setting iscsi_auth_order=CHAP, initiator authorization will be performed at
the end of the login phase for an iSCSI normal session: before going to the full feature
phase, the target will check its ACL. If this iSCSI connection does not match any ACL
provisioned, the login attempt will be terminated.
4.11.3. iscsi_target_vendor_id
Options: A string of maximum of 8 characters, defaults to CHISCSI
The iscsi_target_vendor_id is part of the device identification sent by an iSCSI target in
response of a SCSI Inquiry request.
iscsi_offload_mode has no meaning when the iSCSI software is used on a non-
TOE based NIC.keyfile from Chelsio support.
iscsi_auth_order has no meaning when ACL_Enable is set to No on a target.
