in a stack member becoming a disabled master, which has the configuration as a
normal stack master except that all its switchports are shutdown.

Overview and Configuration
When the DMM feature is enabled, the disabled master will continue to monitor
the health of the original stack master over the stack resiliency link connection. If
the original stack master were to fail, when the DMM feature is enabled, then the
disabled master will detect this and will automatically re-enable its switchports.
This ensures that the stack will continue to pass network traffic, even if a
catastrophic stack failure occurs.
For more information about the DMM feature when the stack member is a disabled
master, see
