CAUTION:
 To ensure that DLDP works properly on a link, you must configure the full duplex mode for the ports at two ends
of the link, and configure a speed for the two ports, rather than letting them negotiate a speed. For more
information about the duplex and speed commands, see the Layer 2—LAN Switching Command Reference .
 For DLDP to work properly, enable DLDP on both sides and make sure these settings are consistent: the interval
to send Advertisement packets, DLDP authentication mode, and password.
 DLDP does not process any link aggregation control protocol (LACP) events. The links in an aggregation are
treated as individual links in DLDP.
 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 switch, enable DLDP globally, and then enable it on each port.
Follow these steps to enable DLDP:

NOTE:
 DLDP takes effect only on Ethernet interfaces (optical or copper).
 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.
