To set the shared secrets with a WWN, interactively:
switch:admin> secAuthSecret "--set"
This command is used to set up secret keys for the DH-CHAP authentication.
The minimum length of a secret key is 8 characters and maximum 40
characters. Setting up secret keys does not initiate DH-CHAP
authentication. If switch is configured to do DH-CHAP, it is performed
whenever a port or a switch is enabled.
Following inputs should be specified for each entry.
1. WWN for which secret is being set up.
2. Peer secret: The secret of the peer that authenticates to peer.
3. Local secret: The local secret that authenticates peer.

To remove all secret keys:
switch:admin> secAuthSecret "--remove --all"
This command deletes database of DH-CHAP secret keys. If a fabric
requires authentication, deleting this database may cause switch
to segment from the fabric.
Do want to remove secret key database? (yes, y, no, n): [no] y
Deleting secret key database... Done.
