Task
Setting DLDP mode
Setting the interval for sending advertisement packets
Setting the DelayDown timer
Setting the port shutdown mode
Configuring DLDP authentication
Resetting DLDP state
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

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:
To do...
Enter system view
Enable DLDP globally
Enter Ethernet
port view or port
group view
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.
Use the command...

dldp enable
Enter Ethernet interface interface-type
