Re: iSCSI: Digests and Multiple Connections

Julian,

My question was about digests only and you ought to put that
assertion in Appendix D to avoid confusion.

Prasenjit,

Digests and security are connection level characteristics.

The standard says:

When Initiator and Target agree on a digest, this digest MUST be used
for every PDU in full feature phase.

Also, it appears that digests are a session-level parameter.

Scenario:

The first connection of a multiple-connection session agrees on digests
and proceeds to full-feature phase with digests.

What about the subsequent connections that try to login? Do these
connections
suspend digests during non-full feature phase and turn it on during
full feature.

The standard is silent on this issue.
