Table 17 DLDP neighbor states
DLDP nei

hbor state Descri

tion
Unknown
A neighbor is in this state when it is just detected and is being probed. A neighbor is
in this state only when it is being probed. It transits to Two way state or Unidirectional
state after the probe operation finishes.
Two way
A neighbor is in this state after it receives response from its peer. This state indicates
the link is a two-way link.
Unidirectional
A neighbor is in this state when the link connecting it is detected to be a unidirectional
link. After a device transits to this state, the corresponding neighbor entries
maintained on other devices are removed.
DLDP configuration task list
For DLDP to work correctly, 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.
Make sure that the DLDP version running on devices on the two ends are the same.
Complete the following tasks to configure DLDP:

Configuring the duplex mode and speed of an Ethernet interface Required
Enabling DLDP Required
Setting DLDP mode Optional

Configuring the duplex mode and speed of an
Ethernet interface
To make sure DLDP works correctly 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.
To configure the duplex mode and speed of an Ethernet interface:
