Fabric OS reference guide Operands Examples The operands are: --show --set value Displays local authentication configuration. Modifies authentication configuration. Values are: - -a value, which sets authentication protocol. Specify fcap to set FCAP authentication only, dhchap to set DH-CHAP authentication only, and all to set FCAP and DH-CHAP (default). When authentication is set to all, implicit order is FCAP and then DH-CHAP; for instance, authentication negotiation FCAP is given priority over DH-CHAP on the local switch, but you can still select DH-CHAP. - -g value, which sets Diffie-Hellman group (DH group). Values 0 through 4 and * are valid. DH group 0 is called NULL DH. Each DH group specifies a key size and associated parameters implicitly. A higher group value provides stronger cryptography and a higher level of security with the authentication protocol. When the DH group is set to a specified value, only that DH group is enabled in authentication. Specifying * as a group enables all DH groups (0, 1, 2, 3, and 4, in that order: default). For instance, authentication negotiation NULL DH is given priority over other groups, but you can still select other DH groups. To display authentication configuration on the switch: switch:admin> authutil "--show" AUTH TYPE HASH TYPE GROUP TYPE fcap,dhchap sha1,md5 0,1,2,3,4 To set DH-CHAP as the authentication protocol: switch:admin> authutil "--set -a dhchap" Committing configuration...done. Authentication is set to dhchap. To set both protocols, in order of FCAP and then DH-CHAP: switch:admin> authutil "--set -a all" Committing configuration...done. Authentication is set to fcap,dhchap. 160 Fabric OS 3.x Document Addendum
