VSANs—DHCHAP authentication is not done on a per-VSAN basis.
On—During switch initialization, if the connecting device supports DHCHAP authentication, the
software performs the authentication sequence. If the connecting device does not support DHCHAP
authentication, the link is placed in an isolated state.
Auto-Active—During switch initialization, if the connecting device supports DHCHAP
authentication, the software performs the authentication sequence. If the connecting device does not
support DHCHAP authentication, the software continues with the rest of the initialization sequence.
Auto-Passive (default)—The switch does not initiate DHCHAP authentication, but participates in
DHCHAP authentication if the connecting device initiates DHCHAP authentication.
Off—The switch does not support DHCHAP authentication. Authentication messages sent to ports
in this mode return error messages to the initiating switch.
