Problem:

Versa FlexVNF continuously restarts. What should I check to resolve this? 


Solution:

Versa FlexVNF requires at least one data network interfaces to be operational. 


Follow these steps to resolve this issue:

  1. Open the /var/log/versa/versa-service.log log file and check for the following content in it.
    Cause: No Ethernet ports - bye
    Jun 19 03:21:12AM 2017 ERROR [0] vsm_exit_handler:1521 Unexpected exit from vsmd
    versa-vsmd: ../usr/sbin/vsm/vsm.c:1522: vsm_exit_handler: Assertion `0' failed.


  2. Ensure you have more than one interface in your configuration.
  3. If you have more than one interface in your configuration and still see this log, then check the drivers of all the interfaces in your configuration.    
  4. Run the ethtool -i  <Port> command to check the drivers.

     NOTE: Versa FlexVNF only supports  VIRTIO and VMXNET3 drivers. 
     
  5. Select any one of these drivers if your interface has a different driver.
  6. Restart the device.
