Configuring DLDP 65

The configuration on Switch B is the same as that on Switch A.

Precautions

1When enabling DLDP on two connected devices, make sure that they are using the same software version. Otherwise, DLDP may malfunction.

2When optical fibers are cross-connected, two or three ports are in the disable state, and the remaining ports are in the inactive state.

3DLDP in the enhanced mode can identify unidirectional links caused by fiber cross-connection or fiber cut.

4DLDP in the normal mode can identify only unidirectional links caused by fiber cross-connection.

5You are recommended to set the Delaydown timer to 5 seconds on the DLDP-enabled devices that are connected with each other.
