Enabling Dldp; Setting Dldp Mode - H3C LS-3100-52P-OVS-H3 Operation Manual

To ensure unidirectional links can be detected, make sure these settings are the same on the both
sides: DLDP state (enabled/disabled), the interval for sending Advertisement packets,
authentication mode, and password.
Keep the interval for sending Advertisement packets adequate to enable unidirectional links to be
detected in time. If the interval is too long, unidirectional links cannot be terminated in time; if the
interval is too short, network traffic may increase in vain.
DLDP does not process any link aggregation control protocol (LACP) events. The links in an
aggregation group are treated individually in DLDP.
When connecting two DLDP-enabled devices, make sure the DLDP software version ID fields of
the DLDP packets exchanged between the two devices are the same. Otherwise, DLDP may
operate improperly.
