Enabling DLDP

To properly configure DLDP on the device, first enable DLDP globally, and then enable it on each port.
To enable DLDP:

• Enter system view
• Enable DLDP globally
• Enter

• Enable DLDP
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.

Setting DLDP mode

DLDP works in normal or enhanced mode.
In normal mode, DLDP does not actively detect neighbors when the corresponding neighbor entries age
out.
In enhanced mode, DLDP actively detects neighbors when the corresponding neighbor entries age out.
To set DLDP mode:
To do...
• Enter system view

Setting the interval to send advertisement packets

DLDP detects unidirectional links by sending Advertisement packets. To make sure that DLDP can detect
unidirectional links promptly without affecting network performance, set the advertisement interval
appropriately depending on your network environment. The interval should be set shorter than one third
of the STP convergence time. If the interval is too long, STP loops may occur before unidirectional links
