z When you configure a DLDP authentication mode and authentication password on a port, make
sure that the same DLDP authentication mode and password are set on both the local port and the
peer port. Otherwise, DLDP authentication fails.
z DLDP cannot work before DLDP authentication succeeds.
Examples
# Set the DLDP authentication mode and password to plain text and abc on the ports fiber-connect
devices A and B.
z Configure device A
<SysnameA> system-view
System View: return to User View with Ctrl+Z.
[SysnameA] dldp authentication-mode simple abc
z Configure device B
<SysnameB> system-view
System View: return to User View with Ctrl+Z.
[SysnameB] dldp authentication-mode simple abc
dldp interval
Syntax
dldp interval timer-value
undo dldp interval
View
System view
Parameters
timer-value: Interval for sending DLDP advertisement packets, in the range 1 to 100 (in seconds).
Description
Use the dldp interval command to set the interval for sending DLDP advertisement packets for all
DLDP-enabled ports in the advertisement state.
Use the undo dldp interval command to restore the default.
By default, the interval for sending DLDP advertisement packets is 5 seconds.
Note that:
z The interval takes effect on all the DLDP-enabled ports.
z It is recommended that you set the interval shorter than one-third of the STP convergence time
(usually 30 seconds). If too long an interval is set, an STP loop may occur before DLDP shuts down
unidirectional links. On the contrary, if too short an interval is set, network traffic increases,
unnecessarily consuming port bandwidth.
