## Symptoms

- VSX Gateway / VSX cluster member reconfiguration operation (e.g., '`vsx_util reconfigure`', '`vsx_util add_member_reconf`') fails with the following error:

`Error: Interface '`*interface_name*`' exists in the management database, but not on the gateway.`

*Example*:

```

[Expert@MGMT:0]# vsx_util add_member_reconf

Enter Security Management Server/main Domain Management Server IP address (Hit 'ENTER' for 'localhost'): X.X.X.X 
Enter Administrator Name: admin

Enter Activation Key: zzz

**** Error: Interface 'sit0' exists in the management database, but not on the gateway. 
**** If this interface is not in use, please remove it from the VSX 'my_cluster' Physical Interfaces tab. 
**** Configuration information for Member_C failed verification. 
Aborting reconfiguration ... 
Database saved successfully.

===================== SUMMARY ===================== 
**** Reconfigure gateway operation failed.
```

## Cause

Possible reasons:

* The physical slave interface is really missing on the VSX Gateway.
* The physical slave interface was not deleted from the VSX object in SmartDashboard.
* The Bond interface does not have an IP address or a VLAN assigned to it.
* The name of the physical slave interface is '`sit0`' (interface that used for IPv6 tunneling), and IPv6 is not configured on the VSX Gateway.
