Use the undo dldp authentication-mode to remove the DLDP authentication mode and password on
the current port.
By default, the authentication mode on the current port is none.
Note that:
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 the ports connected with a fiber
cable or copper twisted pair. Otherwise, DLDP authentication fails. DLDP cannot work before DLDP
authentication succeeds.
Related commands: dldp unidirectional-shutdown.
Examples
# Set the DLDP authentication mode and password to plain text and abc respectively on the ports
connected with a fiber cable or copper twisted pair between Switch A and Switch B.

dldp interval
Syntax
dldp interval timer-value
undo dldp interval
View
System view
Parameters
timer-value: Interval between sending advertisement packets in seconds, in the range of 1 to 100. It is 5
by default.
Description
Use the dldp interval command to set the interval between sending advertisement packets for all
DLDP-enabled ports in the advertisement state.
Use the undo dldp interval command to restore the interval to the default value.
By default, the interval between sending advertisement packets is 5 seconds.
A device in Advertisement state periodically sends out Advertisement packets to notify the neighbors of
its existence. Meanwhile, the device also retrieves neighbor information from the received
Advertisement packets and maintains its own neighbor entries. When the device receives an
Advertisement packet from a device that does not match any of its neighbor entries, it transits from
Advertisement state to Probe state and sends DLDP Probe packets to detect unidirectional links.
