Configuring DLDP authentication

You can guard your network against attacks and malicious probes by configuring an appropriate
DLDP authentication mode, which can be simple authentication or MD5 authentication. If your
network is safe, you can choose not to authenticate.
To enable DLDP to operate correctly, make sure that DLDP authentication modes and passwords on
both sides of a link are the same.
To configure DLDP authentication:
Step
1. Enter system view.
2. Configure DLDP
authentication.

Resetting DLDP state

After DLDP detects a unidirectional link on a port, the port enters Disable state. In this case, DLDP
prompts you to shut down the port manually, or it shuts down the port automatically depending on the
user-defined port shutdown mode. To enable the port to perform DLDP detect again, you can reset
the DLDP state of the port by using one of the following methods:
•
If the port is shut down with the shutdown command manually, run the undo shutdown
command on the port.
•
If DLDP automatically shuts down the port, run the dldp reset command on the port to enable
the port to perform DLDP detection again. Alternatively, you can wait for DLDP to automatically
enable the port when it detects that the link has been restored to bidirectional. For information
about how to reset the DLDP state by using the dldp reset command, see
state in system
The DLDP state that the port transits to upon the DLDP state reset operation depends on its physical
state. If the port is physically down, it transits to Inactive state. If the port is physically up, it transits to
Active state.
