AHS could be used for more than encapsulating an extended CDB - Julo

Hello,

Since section 9.2 states "iSCSI response PDUs do not have AH segments"
why do SCSI response PDU, Task Management Resp PDU etc.. have TotalAHSLength?
Shouldn't it be reserved. In addition DataSegmentLength to be made reserved
in most of the response pdus e.g. Task Mgt resp etc..

Thanks,
Ashok

Ashok,

    TotalAHSLength must be 0 "reserved" for PDUs that don't have AHS.
AHS is only used to encapsulate an extended CDB. This scenario
TotalAHSLength would be 0.
