Cisco SAN switches support authentication features to address physical security (see the following figure).
Figure 41: Switch and Host Authentication
Fibre Channel host bus adapters (HBAs) with appropriate firmware and drivers are required for host-switch
authentication.
Note
Configuring DHCHAP Authentication
You can configure DHCHAP authentication using the local password database.
Before You Begin
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.
