Parameters
md5: Specifies the MD5 authentication mode.

Usage guidelines
To enable DLDP to operate correctly, make sure the DLDP authentication modes and the passwords
configured on the two ends of a link are the same.
If you do not configure the authentication password after you configure the authentication mode, the
authentication mode is none no matter which authentication mode you configure.
Examples
# Configure to perform plain text authentication and set the password to abc (assuming that Device A
and Device B are connected by a DLDP link).
• Configure Device A:
<DeviceA> system-view
[DeviceA] dldp authentication-mode simple
[DeviceA] dldp authentication-password simple abc
• Configure Device B:
<DeviceB> system-view
