## Symptoms

- * Pushing VSX configuration in SmartDashboard fails with the following error (e.g., open VSX Gateway object and just click on OK):

  ```
  
  Checking connection with VSX 
  Error: failed to construct interface name with address 
  Virtual System Processing Completed with Errors 
  
  Pushing network configuration to Virtual System operation has finished with errors. 
           Refer to the messages retrieved during the VSX push configuration stage 
           and make sure that the configuration you are trying to push is legal. 
           If the problem persists contact Check Point Technical Support. 
  
  Operation has failed.
  ```

* When checking the "Topology" settings in VSX Gateway / VSX cluster object, there is an interface without IP address / Subnet mask.

* After editing the problematic interface in VSX Gateway / VSX cluster object, pushing of VSX configuration fails with:  

  "`Internal error: Cannot resolve interface name from vs_interface set`"  

  Following [sk107714](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk107714) does not help.

* Output of "*ifconfig -a*" command on the VSX Gateway / VSX cluster members shows that the problematic interface is configured correctly.
