Clearpass --> controller communication

  • 1.  Clearpass --> controller communication

    Posted Aug 07, 2014 12:42 PM

    I installed a new Local controller, and I entered the new controller IP address in the Clearpass network device list.
    Now the Clearpass server shows authentication errors in the Event Viewer as:

     

    Received packet from 10.0.2.18 with invalid Message-Authenticator! (Shared secret is incorrect.)

     

    This seems odd to me, since the Local controller got its config from the master controller, and the master and two other Locals are working just fine.

     

    I'm tempted to reset the password on the master controller for the clearpass server and in clearpass under the device list.

    But before I do that, I want to make sure that communication between the two doesn't go down...... Is this password only used in those two places?

     

    Thank you,

    Tony

    The easiest way to check is duplicate the master's device in network device section of ClearPass using the "Copy" button at the bottom and just change the IP to the locals. This ensures the secret is the same.

    Hi Tim:

    Copying another controller's profile did the trick!

    Thank you!

    Did you added the local controller to the devices list in ClearPass ? and if so can you confirm it has the same shared key?
