About DHCHAP Authentication Modes
The DHCHAP authentication status for each interface depends on the configured DHCHAP port mode.
When the DHCHAP feature is enabled in a switch, each Fibre Channel interface or FCIP interface may be
configured to be in one of four DHCHAP port modes:
• On—During switch initialization, if the connecting device supports DHCHAP authentication, the software
• Auto-Active—During switch initialization, if the connecting device supports DHCHAP authentication,
• Auto-Passive (default)—The switch does not initiate DHCHAP authentication, but participates in
• Off—The switch does not support DHCHAP authentication. Authentication messages sent to such ports
Note
Whenever DHCHAP port mode is changed to a mode other than the Off mode, reauthentication is performed.
Changing DHCHAP port mode for a VE link requires a port flap on both the ends.
The following table identifies the switch-to-switch authentication behavior between two Cisco MDS switches
in various modes.
