Optional) Setting The Authentication Mode Of Dldp Packets; Checking The Configuration - Huawei Quidway S3700 Series Configuration Manual

Quidway S3700 Series Ethernet Switches
Configuration Guide - Reliability
An interface in DLDP Down state still sends RecoverProbe packets periodically. If correct
RecoverEcho packets are received, it indicates that the unidirectional link changes to the
bidirectional link and the DLDP status becomes Up.

1.2.8 (Optional) Setting the Authentication Mode of DLDP Packets

Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
dldp authentication-mode { md5 md5-password | none | simple simple-password }
The DLDP authentication mode used between the interfaces of the S3700 and the remote device
is set.
By default, the DLDP authentication mode used between the interfaces of the S3700 and the
remote device is none. That is, DLDP packets are not authenticated.
----End

1.2.9 Checking the Configuration

Procedure
Step 1 Run the display dldp [ interface interface-type interface-number ] command to check the DLDP
configuration and neighbor entries.
----End
Example
Run the display dldp command, and you can view the operation mode of DLDP, interval for
sending Advertisement packets, value of the Delay Down timer, interface disabling mode, and
authentication mode of DLDP packets.
<Quidway> display dldp
DLDP global status : enable
DLDP interval : 5s
DLDP work-mode : enhance
DLDP authentication-mode : simple, password is 123
DLDP unidirectional-shutdown : auto
DLDP delaydown-timer : 2s
The number of enabled ports is 2.
The number of global neighbors is: 2.
Interface Ethernet0/0/1
Issue 01 (2011-10-26)
NOTE
Ensure that the local and remote devices use the same authentication mode and same authentication
password; otherwise, the DLDP authentication fails. DLDP works normally only after the DLDP
authentication succeeds.
