7 Authentication policy for fabric elements Authentication protocols Use the authUtil command to perform the following tasks: • Display the current authentication parameters. • Select the authentication protocol used between switches. • Select the DH (Diffie-Hellman) group for a switch. Run the authUtil command on the switch you want to view or change. Below are the different options to specify which DH group you want to use. • 00 - DH Null option • 01 - 1024 bit key • 02 - 1280 bit key • 03 - 1536 bit key • 04 - 2048 bit key Viewing the current authentication parameter settings for a switch 1. Log in to the switch using an account with admin permissions, or an account with the O permission for the Authentication RBAC class of commands. 2. Enter the authUtil --show. Example of output from the authUtil --show command AUTH TYPE HASH TYPE GROUP TYPE fcap,dhchap sha1,md5 0, 1, 2, 3, 4 Switch Authentication Policy: PASSIVE Device Authentication Policy: OFF Setting the authentication protocol 1. Log in to the switch using an account with admin permissions, or an account with OM permissions for the Authentication RBAC class of commands. 2. Enter the authUtil --set -a command specifying fcap, dhchap, or all. Example of setting the DH-CHAP authentication protocol switch:admin> authutil --set -a dhchap Authentication is set to dhchap. When using DH-CHAP, make sure that you configure the switches at both ends of a link. NOTE If you set the authentication protocol to DH-CHAP or FCAP, have not configured shared secrets or certificates, and authentication is checked (for example, you enable the switch), then switch authentication will fail. If the E_Port is to carry in-flight encrypted traffic, the authentication protocol must be set to DH-CHAP. You must also use the -g option to set the DH group value to group 4 or all groups. See Chapter 14, "In-flight Encryption and Compression," for details about in-flight encryption. 212 Fabric OS Administrator's Guide 53-1002745-02
