DHCHAP is a mandatory password-based, key-exchange authentication protocol that supports both
switch-to-switch and host-to-switch authentication. DHCHAP negotiates hash algorithms and DH
groups before performing authentication. It supports MD5 and SHA-1 algorithm-based authentication.
To configure DHCHAP authentication using the local password database, perform this task:
Enable DHCHAP.
Step 1
Identify and configure the DHCHAP authentication modes.
Step 2
Configure the hash algorithm and DH group.
Step 3
Configure the DHCHAP password for the local switch and other switches in the fabric.
Step 4
Configure the DHCHAP timeout value for reauthentication.
Step 5
Verify the DHCHAP configuration.
Step 6

SAN port channel interfaces—If DHCHAP is enabled for ports belonging to a SAN port channel,
DHCHAP authentication is performed at the physical interface level, not at the port channel level.
Port security or fabric binding—Fabric-binding policies are enforced based on identities
authenticated by DHCHAP.
