Setting DLDP unidirectional-shutdown mode
On the detection of a unidirectional link, the port can be shut down either automatically or manually. This setting controls whether the shutdown is automatic or manual.
When DLDP detects a unidirectional port, an event is logged and the port must be shut down manually by an administrator. In the event that the link state is restored to bidirectional and the shutdown mode is manual, the user must manually bring up the port. Any dynamic change of the shutdown mode (that is, auto to manual) will take effect only when DLDP is disabled globally and enabled again. Likewise, When the link state is restored to Bidirectional and the shutdown mode is manual, the user must manually bring up the port.
Also, any dynamic change of the shutdown mode (that is, auto->manual/vice versa) will be taken into effect only when DLDP is disabled globally and enabled back again
