DLDP neighbor
state
Description
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.
1.2 DLDP Configuration Task List
Complete the following tasks to configure DLDP:
Task Remarks
Enabling DLDP Required
Setting DLDP Mode Optional
Setting the Interval for Sending Advertisement Packets Optional
Setting the DelayDown Timer Optional
Setting the Port Shutdown Mode Optional
Configuring DLDP Authentication Optional
Resetting DLDP State Optional
Note that:
z
DLDP works only when the link is up.
z
To ensure unidirectional links can be detected, make sure these settings are the
same on the both sides: DLDP state (enabled/disabled), the interval for sending
Advertisement packets, authentication mode, and password.
z
Keep the interval for sending Advertisement packets adequate to enable
unidirectional links to be detected in time. If the interval is too long, unidirectional
links cannot be terminated in time; if the interval is too short, network traffic may
increase in vain.
z
LACP (Link Aggregation Control Protocol) events have no effect on DLDP. Links
in an aggregation group are treated individually in DLDP.
z
802.1X has no effect on DLDP.
z
When connecting two DLDP-enabled devices, make sure the DLDP version ID
fields of the DLDP packets exchanged between the two devices are the same.
Otherwise, DLDP may operate improperly.
