About Enabling DHCHAP

By default, the DHCHAP feature is disabled in all Cisco Nexus 5000 Series switches.
You must explicitly enable the DHCHAP feature to access the configuration and verification commands
for fabric authentication. When you disable this feature, all related configurations are automatically
discarded.

Command
Step 1
switch# configuration terminal
Step 2

About DHCHAP Authentication Modes

The DHCHAP authentication status for each interface depends on the configured DHCHAP port mode.
When the DHCHAP feature is enabled in a switch, each Fibre Channel interface or FCIP interface may
be configured to be in one of four DHCHAP port modes:
•
•
•
•
Whenever DHCHAP port mode is changed to a mode other than the Off mode, reauthentication is

performed.

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.
