Configuring DLDP
65
The configuration on Switch B is the same as that on Switch A.
Precautions
1 When enabling DLDP on two connected devices, make sure that they are using the
same software version. Otherwise, DLDP may malfunction.
2 When optical fibers are cross-connected, two or three ports are in the disable
state, and the remaining ports are in the inactive state.
3 DLDP in the enhanced mode can identify unidirectional links caused by fiber
cross-connection or fiber cut.
4 DLDP in the normal mode can identify only unidirectional links caused by fiber
cross-connection.
5 You are recommended to set the Delaydown timer to 5 seconds on the
DLDP-enabled devices that are connected with each other.
