    Hi Community,

     

    i want to share with you the feedback how to get CVP (Cloudvision Portal) running with CPPM (6.7) over Tacacs+ Service. Normally you get the network-operator role if you successfully authenticate. If you need the network-admin cvp-role you need to follow these steps:

     

    Pre-Konfig:

    You have CVP configured with shared secret to CPPM

     

    Now, create a Tacacs Dictonary "Addon" to the shell.

     

    Go to Administration-> Dictonarys -> Tacacs+ Services. Mark the "shell" and Export the XML.

     

    Add the follow line

     

    <ServiceAttribute allowedValuesCsv="network-admin" dataType="String" dispName="cvp-roles" name="cvp-roles"/>

     

    above the last one:

     

       </TacacsServiceDictionary>
      </TacacsServiceDictionaries>
    </TipsContents>

     

    so it looks like:

    ...truncated...

          <ServiceAttribute allowedValuesCsv="network-admin" dataType="String" dispName="cvp-roles" name="cvp-roles"/>
        </TacacsServiceDictionary>
      </TacacsServiceDictionaries>
    </TipsContents>

     

    in the end.

    Import those XML again and make sure CPPM got it. Then Create a Tacacs+ Enforcement Profile that looks like this:

    cvp.PNG

    Be careful that you use REPLACE, otherwise it will be the default operator.

    Add this enforcement to you Tacacs Service or create a new one only for CVP.

     

    Ill hope this helps. If you want to extend the system with more roles you have to add more XML Lines, each one for a new role that matches the cvp role.

     

    Thanks to Aruba/Arista TAC.
