Unmerge the Management Interface

The threat defense 7.4 and later supports a merged Management and Diagnostic interface. If you need to unmerge your interfaces, perform this procedure. We recommend using unmerged mode temporarily while you migrate your network to a merged mode deployment. Separate Management and Diagnostic interfaces may not be supported in all future releases.

Unmerging the interfaces does not restore your original Diagnostic configuration (if you upgraded and then merged your interfaces). You will need to reconfigure the Diagnostic interface manually. Also, the Management interface will now be named "management"; you cannot rename it "diagnostic."

Alternatively, if you used the Backup function to save an old unmerged configuration, you can restore that configuration or you can use the or management center configuration rollback feature, and the device will be in an unmerged state with the Diagnostic configuration intact.

Before you begin

To view the current mode of the device, enter the show management-interface convergence command at the threat defense CLI. The following output shows that the Management interfaces are merged:
```
> show management-interface convergence
management-interface convergence
>                   
```
The following output shows that the Management interfaces are not merged:
```
> show management-interface convergence
no management-interface convergence
>                   
```
For High Availability pairs and clusters, perform this task on the active/control unit. The merged configuration will be replicated automatically to the standby/data units.

Procedure

Step 1

Choose Devices > Device Management, and click Edit ( edit icon ) for your threat defense. The Interfaces page is selected by default. .

Step 2

For the Management interface, click Unmerge Management Interface ( Unmerge Management Interface ).

Step 3

Click Yes to confirm that you want to unmerge the interface.

Step 4

Deploy the new unmerged configuration.

Note	If you restore a configuration that is merged, or roll back to a merged configuration, then the device will revert to that merged configuration.

After the merge, the Management interface is no longer shown on the Interfaces page.
