z
For DLDP to work properly, enable DLDP on both sides and make sure these settings are
consistent: the interval for sending Advertisement packets, DLDP authentication mode, and
password.
z
DLDP does not process any link aggregation control protocol (LACP) events. The links in an
aggregation are treated as individual links in DLDP.
z
For DLDP to operate properly, make sure the DLDP version running on devices on the two sides
are the same.
Enabling DLDP
To properly configure DLDP on the device, you need to first enable DLDP globally, and then enable it on
each port.
Follow these steps to enable DLDP:

z
DLDP takes effect only on Ethernet interfaces (optical or copper).
z
DLDP can detect unidirectional links only after all physical links are connected. Therefore, before
enabling DLDP, make sure that optical fibers or copper twisted pairs are connected.
Setting DLDP Mode
There are two DLDP modes:
z
Normal mode: In this mode, DLDP does not actively detect neighbors when the corresponding
neighbor entries age out. The system can identify only one type of unidirectional links:
cross-connected fibers.
