DHCHAP Compatibility with Existing Cisco MDS Features

This section identifies the impact of configuring the DHCHAP feature along with existing Cisco MDS features:

• PortChannel interfaces—If DHCHAP is enabled for ports belonging to a PortChannel, DHCHAP authentication is performed at the physical interface level, not at the PortChannel level.
• FCIP interfaces—The DHCHAP protocol works with the FCIP interface just as it would with a physical interface.
• Port security or fabric binding—Fabric binding policies are enforced based on identities authenticated by DHCHAP.
• VSANs—DHCHAP authentication is not done on a per-VSAN basis.
• High availability—DHCHAP authentication works transparently with existing HA features.
