 Note:
z When you use the dldp enable/dldp disable command in system view to
enable/disable DLDP on all optical ports of the switch, the configuration takes effect
on the existing optical ports, instead of those added subsequently.
z DLDP can operate normally only when the same authentication mode and
password are set on the local and peer ports.
z When the DLDP protocol works in the normal mode, the system can identify only
one type of unidirectional link caused by fiber cross-connection.
z When the DLDP protocol works in enhanced mode, the system can identify two
types of unidirectional links: one is caused by fiber cross-connection and the other is
caused by one fiber being not connected or being broken.
z When the device is busy with services and the CPU utilization is high, DLDP may
issue mistaken reports. You are recommended to configure the operating mode of
DLDP as manual after unidirectional links are detected, so as to reduce the
influence of mistaken reports.
