Note Fibre Channel Host Bus Adapters (HBAs) with appropriate firmware and drivers are required for
host-switch authentication.
DHCHAP
DHCHAP is an authentication protocol that authenticates the devices connecting to a switch. Fibre
Channel authentication allows only trusted devices to be added to a fabric, which prevents unauthorized
devices from accessing the switch.
Note The terms FC-SP and DHCHAP are used interchangeably in this chapter.
