Device authentication policy Device authentication policy can also be categorized as an HBA authentication policy. Fabric wide distribution of the device authentication policy is not supported since the device authentication requires manual interaction in setting the HBA shared secrets and switch shared secrets, and most of the HBAs do not support the defined DH groups for use in the DH-CHAP protocol. By default the switch will be in OFF state, which means the switch will clear the security bit in the FLOGI (fabric login). The authutil command provides an option to change the device policy mode to select PASSIVE policy, which means switch responds to authentication from any device and does not initiates authentication to devices. $authutil --policy -dev The following are the available policy modes and properties. OFF (Default): Authentication is not required. Even if device sends FLOGI with security bit set, switch accepts the FLOGI with security bit OFF. In this case, switch assumes no further authentication requests from device. PASSIVE: Authentication is optional. If the attached device is capable of doing the authentication then the switch participates in authentication; otherwise it will form an F_Port without authentication. In PASSIVE mode, an F_Port will be disabled if the HBA shared secret does not match with the secret installed on the switch. If the secret provided by the switch does not match the secrets installed on the HBA then the HBA will disable the port on its side. On any authentication handshaking rejection, the switch will disable the F_Port with reason "Authentication rejected". Since the F_Port authentication requires DH-CHAP protocol, selecting the PASSIVE mode will be blocked if only FCAP protocol is selected as the authentication protocol. Similarly de-selecting the DH-CHAP protocol from the authentication protocol list will be blocked if the device authentication is set to PASSIVE. Auth policy restrictions Fabric OS 5.1.0 implementation of DH-CHAP/FCAP does not support integration with RADIUS. All fabric element authentication configurations are performed on a local switch basis. Device authentication policy supports devices that are connected to the switch in point-to-point manner and is visible to the entire fabric. The following are not supported: • Public loop devices • Single private devices • Private loop devices • Mixed public and private devices in loop • NPIV devices • FICON channels Supported configurations The following HBAs support authentication: • Emulex LP11000 (Tested with Storport Miniport v2.0 windows driver) • Qlogic QLA2300 (Tested with Solaris v5.04 driver) 132 Configuring advanced security
