9. Using FC-SP DHCHAP Authentication (Windows, Linux 8.2 and Solaris)
DHCHAP Tab

authentication failure is assumed (no authentication is performed). The time
value ranges from 20 to 999 seconds.

Bi-Directional – If enabled, the adapter driver supports authentication initiated
by either the switch or the adapter. If disabled, the driver supports adapter
initiated authentication only.

Re-authenticate – If enabled, the driver can periodically initiate authentication.

Re-auth Interval – The value in minutes that the adapter driver uses to
periodically initiate authentication. Valid interval ranges are 10 to 3600 minutes.
The default is 300 minutes.

DH Priority – The priority of the five supported DH Groups (Null group, and
groups 1,2,3, and 4) that the adapter driver presents during the DHCHAP
authentication negotiation with the switch.

Hash Priority – The priority of the two supported hash algorithms (MD5 and
SHA1) that the adapter driver presents during the DHCHAP authentication
negotiation with the switch (default is MD5 first, then SHA1,2,3...).
State Area

State – Possible states are Not Authenticated, Authentication In Progress,
Authentication Success and Authentication Failed.
Changing Authentication Configuration
To view or change authentication configuration:
1. In the discovery-tree, select the adapter whose configuration you want to view or
change.
2. Select the DHCHAP tab. (If the fields on this tab are “grayed out” (disabled)
authentication has not been enabled at the driver level.)
3. Change configuration values as you want.
Note: You can only configure DHCHAP on the local host.
4. Click Apply. You are prompted for the current password (local password) to
validate the configuration change request. The verification request only appears if a
local password has been defined for this adapter.
5. Enter the password and click OK.
To return settings to the status before you started this procedure, click Restore
before you click Apply. Once you click Apply, changes can not be cancelled.
To return all settings to the default configuration, click Defaults. Be careful as this
also resets the password(s) to NULL for this configuration.
To initiate an immediate authentication, click Initiate Authentication. This request
is sent to the driver, even if you have not made any changes to the setup.
Note: To successfully authenticate with the switch using DHCHAP, you only need
to set the configuration mode to enabled and set the local password. The
local password must be set to the identical value as the switch for the
DHCHAP authentication to succeed.
