1.2.5 Setting the Port Shutdown Mode
On detecting a unidirectional link, the ports can be shut down in one of the following two
modes.
z
Manual mode. This mode applies to networks with low performance, where normal
links may be treated as unidirectional links. It protects service packet transmission
against false unidirectional links. In this mode, DLDP only detects unidirectional
links and generates log and traps. The operations to shut down unidirectional link
ports are accomplished by the administrator.
z
Auto mode. In this mode, when a unidirectional link is detected, DLDP transits to
Disable state, generates log and traps, and set the port as DLDP Down.

Caution:
z
On a port with both remote OAM loopback and DLDP enabled, if the port shutdown
mode is auto mode, the port will be shut down by DLDP when it receives a packet
sent by itself, causing remote OAM loopback to operate improperly. To prevent this,
you need to set the port shutdown mode to auto mode.
z
If the device is busy, or the CPU utilization is high, normal links may be treated as
unidirectional links. In this case, you can set the port shutdown mode to manual
mode to eliminate the effects caused by false unidirectional link report.
