Shut Mode: Once detecting a unidirectional link, the port can be shut down in
one of the following two modes:
Auto: In this mode, DLDP generates logs and traps and
shuts down the corresponding port on detecting
unidirectional links, and the DLDP link state transits to
Disable.
Manual: In this mode, DLDP only generates logs and traps if
it detects unidirectional links, and the operation to shut down
the unidirectional link ports is accomplished by the
administrator.
