2 authUtil authUtil Displays and sets the authentication configuration. SYNOPSIS authutil authutil --show authutil --set option value authutil --policy -sw option | -dev option authutil --authinit [slot/]port[, [slot/]port...] | allE DESCRIPTION NOTES OPERANDS Use this command to display and set local switch authentication parameters. Use --set to change authentication parameters such as protocol, Diffie-Hellman group (DH group), or hash type. When no protocol is set, the default setting of "FCAP, DH- CHAP" is used. When no group is set, the default setting of "*" (meaning "0,1,2,3,4") is used. Configuration settings are saved persistently across reboots. Configuration changes take effect during the next authentication request. Use the --show command to display the current authentication configuration. Authentication parameters are set on a per-switch basis. If Virtual Fabrics are enabled, all authentication parameters apply to the current logical switch context only, and must be configured separately for each logical switch. Use setContext to change the current logical switch context. In a VF environment, authentication is performed only on physical E_Ports, not on logical interswitch links (LISLs). The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for details. This command has the following operands: --show Displays the local authentication configuration.This option is supported in the Access Gateway (AG) mode. --set option value Modifies the authentication configuration. Valid options and their values include the following: -a fcap | dhchap | all Sets the authentication protocol. Specify "fcap" to set only FCAP authentication. Specify "dhchap" to set only DH-CHAP authentication. Specify "all" to set both FCAP and DH-CHAP, which is the default setting. When authentication is set to "all", the implicit order is FCAP followed by DH-CHAP. This means that in authentication negotiation, FCAP is given priority over DH-CHAP on the local switch. If the negotiation is done for an encrypted port, DHCHAP takes precedence over FCAP. The --set dhchap and --set all options are supported in the AG mode. -g 0 | 1 | 2 | 3 |4 | * Sets the Diffie-Hellman (DH) group. Valid values are 0 to 4 and "*". The DH group 0 is called NULL DH. Each DH group implicitly specifies a key size and associated parameters. A higher group value provides stronger cryptography and a higher level of security. When DH group is set to a specified value, only that DH group is 62 Fabric OS Command Reference 53-1002746-01
