Authentication policy for fabric elements 7 Secret key pairs for DH-CHAP When you configure the switches at both ends of a link to use DH-CHAP for authentication, you must also define a secret key pair-one for each end of the link. Use the secAuthSecret command to perform the following tasks: • View the WWN of switches with a secret key pair. • Set the secret key pair for switches. • Remove the secret key pair for one or more switches. Characteristics of a secret key pair • The secret key pair must be set up locally on every switch. The secret key pair is not distributed fabric-wide. • If a secret key pair is not set up for a link, authentication fails. The "Authentication Failed" (reason code 05h) error will be reported and logged. • The minimum length of a shared secret is 8 characters and the maximum length is 40 characters. If the E_Port is to carry in-flight encrypted traffic, a shared secret or at least 32 characters is recommended. See Chapter 14, "In-flight Encryption and Compression" for details about in-flight encryption. NOTE When setting a secret key pair, note that you are entering the shared secrets in plain text. Use a secure channel (for example, SSH or the serial console) to connect to the switch on which you are setting the secrets. Viewing the list of secret key pairs in the current switch database 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 secAuthSecret --show command. The output displays the WWN, domain ID, and name (if known) of the switches with defined shared secrets: WWN DId Name 10:00:00:60:69:80:07:52 Unknown 10:00:00:60:69:80:07:5c 1 switchA Note about Access Gateway switches Because Domain ID and name are not supported for Access Gateway, secAuthSecret --show output for Access Gateway appears as follows: WWN DId Name 10:00:8C:7C:FF:03:9E:00 -1 Unknown 10:00:8C:7C:FF:03:9E:01 -1 Unknown 10:00:8C:7C:FF:0D:AF:01 -1 Unknown When setting and removing the secret for a switch or device on Access Gateway, only the WWN can be used.
