DLDP Configuration

Performing Basic DLDP Configuration

Follow these steps to perform basic DLDP configuration:
Enter system view
Enable DLDP on all optical
ports of the switch
Enable DLDP
Enable
on the current
DLDP
port (a
non-optical
port or an
optical port)
Set the authentication mode and
password
Set the interval of sending DLDP packets
Set the delaydown timer
Set the DLDP handling mode when an
unidirectional link is detected
Set the DLDP operating mode
Note the following when performing basic DLDP configuration.
DLDP can detect unidirectional links only after the links are connected. Therefore, before enabling
DLDP, make sure that optical fibers or copper twisted pairs are connected.
To ensure unidirectional links can be detected, make sure DLDP is enabled on both sides; and the
interval for sending advertisement packets, authentication mode, and password are the same on
both sides.
The interval for sending advertisement packets ranges from 1 to 100 seconds and defaults to 5
seconds. You can adjust this setting as needed to enable DLDP to respond in time to link failures.
If the interval is too long, STP loops may occur before unidirectional links are terminated; if the
interval is too short, network traffic may increase in vain and available bandwidth decreases.
Normally, the interval is shorter than one-third of the STP convergence time, which is generally 30
seconds.
DLDP does not process any link aggregation control protocol (LACP) event, and treats each link in
the aggregation group as independent.
