Cannot communicate with the CMM

Use the information in this section to troubleshoot the chassis when you cannot communicate with the CMM on the data network.

Action​

Complete the following steps until the problem is solved:
  1. Make sure that the correct ports in the connection path are enabled and that you can ping the CMM. If you are unable to ping the CMM, see Cannot ping the CMM on the management network for more information.
  2. Make sure that the protocols that you are using are enabled.
    Note
    By default, only secure protocols are enabled, for example, SSH and HTTPS.
  3. Make sure that you can log into the CMM. If you are unable to log into the CMM, see Cannot log in to the CMM.
  4. Reset the CMM to the default settings by pressing the reset button on the CMM.
Note
You must press and hold the CMM reset button for at least 10 seconds to reset the CMM to default settings. All user-modified CMM configuration settings will be reset to the factory default value.
