65Field DescriptionPackets received Total number of DLDP packets received.Invalid packets received Number of the invalid packets received.Loop packets received Number of the loopback packets received.Authentication failed packets received Number of the received packets that failed to pass theauthentication.Valid packets received Number of the valid packets received.dldp authentication-modeSyntaxdldp authentication-mode { none | { md5 | simple } password }undo dldp authentication-modeViewSystem viewDefault level2: System levelParametersnone: Specifies the switch not to perform authentication.md5: Specifies the MD5 authentication mode and sets a plaintext or ciphertext password.simple: Specifies the simple authentication mode and sets a plaintext or ciphertext password.password: Sets the password. This argument is case sensitive. It must be a plaintext string of 1 to 16characters, or a ciphertext string of 33 to 53 characters.DescriptionUse dldp authentication-mode to configure DLDP authentication.Use undo dldp authentication-mode to restore the default.By default, DLDP authentication is not performed.To enable DLDP to operate correctly, make sure the DLDP authentication modes and the passwords ofboth sides of a link are the same.Examples# Configure the simple authentication mode and set the plaintext password to abc (assuming that SwitchA and Switch B are connected over a DLDP link).• Configure Switch A: system-view[SwitchA] dldp authentication-mode simple abc• Configure Switch B: system-view[SwitchB] dldp authentication-mode simple abc
