z
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.
z
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.
z
DLDP does not process any link aggregation control protocol (LACP) events. The links in an
aggregation group are treated individually in DLDP.
z
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.
