Operating notes

  • If the authentication type MD5 is configured without a md5-auth-key-chain, the authentication will fail.

  • If the md5-auth-key-chain is configured but authentication type not set to MD5, the authentication will fail.

  • If the authentication type MD5 is configured and the md5-auth-key-chain is already configured, the MD5 authentication will begin working.

  • If the md5-auth-key-chain is configured but the authentication type set to MD5, the MD5 authentication will begin working.

  • When the MD5 authentication is working and you remove the md5-auth-key-chain, the MD5 authentication will fail.

  • When the MD5 authentication is working and you change authentication type to other than MD5, the MD5 authentication will fail.

  • When the MD5 authentication is working and you remove the used key-chain from global configuration, the request to remove the used key chain will fail.

  • When the MD5 authentication is working and you remove the key from key-chain in the global configuration, the MD5 authentication will not work.
    NOTE:

    Hewlett Packard Enterprise recommends using a single key in the key-chain.

  • Only RIPv2 is allowed in supporting MD5 authentication.

  • For 2920 switches, the default date and time is 01/01/1990, but for other switches, the default setting is the current date and time. MD5 authentication works only when switches have the same date and time. For MD5 authentication to work when 2920 switches are connected with other switches, you need to manually configure the current date and time or the time needs to be sync with the SNTP server.
