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 [slotnumber]/portnumber[, [slotnumber/]portnumber...] | allE Description 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 --show to display the current authentication configuration. Use portShow to display the authentication type and associated parameters, if applicable, used on the port. Note The execution of this command is subject to Admin Domain restrictions that may be in place. Refer to chapter 1, "Understanding Admin Domain Restrictions" and Appendix A, "Command Availability" for details. Operands When invoked without operands, this command displays the usage. The following operands are supported: --show Displays local authentication configuration. --set value Modifies the authentication configuration. Valid options and their values are: -a fcap |dhchap | all Sets the authentication protocol. Specify "fcap" to set only FCAP authentication, "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. -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. 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 enabled. Specifying "*" enables all DH groups 0, 1, 2, 3, and 4, in that order. This means that in authentication negotiation, the NULL DH group s given priority over all other groups. -h sha1 | md5 | all 40 Fabric OS Command Reference 53-1000599-02
