%Jul 11 17:43:02:362 2018 DeviceA DLDP/6/DLDP_NEIGHBOR_CONFIRMED: A neighbor was
confirmed on interface HundredGigE1/0/2. The neighbor's system MAC is 0023-8956-3600,
and the port index is 2.
%Jul 11 17:43:02:362 2018 DeviceA DLDP/6/DLDP_LINK_BIDIRECTIONAL: DLDP detected a
bidirectional link on interface HundredGigE1/0/2.
%Jul 11 17:43:02:368 2018 DeviceA IFNET/5/LINK_UPDOWN: Line protocol state on the
interface HundredGigE1/0/2 changed to up.
The output shows that the physical status and link status of both HundredGigE 1/0/1 and
HundredGigE 1/0/2 are up and their DLDP neighbors are determined. The links become
bidirectional.

Network configuration

As shown in
Configure DLDP on the devices to meet the following requirements:
•
Each device can detect unidirectional links caused by cross-connected fibers or a
disconnected fiber.
•
When a unidirectional link is detected, the administrator can manually shut down the faulty
port based on the connection status of the link.
•
The interface recovers from failure after the administrator clears the fault and manually brings
up the port.
Figure 3, Device A and Device B are connected through two fiber pairs.
