NOTE:
To enable DLDP to operate correctly, make sure that DLDP authentication modes and passwords
configured on both sides of a link are the same.
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 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 the port is shut down by DLDP automatically, run the dldp reset command on the port, or you can
wait for DLDP to automatically enable the port when it detects that the link has been restored to
bidirectional. For how to reset DLDP state with the dldp reset command, see " Resetting DLDP state
in system view " and " Resetting DLDP state in port view or port group view ."
Upon the DLDP state reset operation, the DLDP state that the port transitions to depends on its physical
state. If the port is physically down, it transitions to Inactive state. If the port is physically up, it transitions
to Active state.
