Enrolling with a preferred cluster

You can specify a preferred cluster in a deployment with multiple clusters. When you do so, the sensor or hybrid appliance submits to this cluster instead of the one it was automatically enrolled with when it was added to the Central Management appliance that also manages the cluster.

Reasons to specify a preferred cluster include:

Geographic proximity—Sensors submit to clusters that are physically close to them to reduce network latency.
Distributed guest-images profiles—Sensors monitoring Windows devices submit to clusters running Windows guest images, and sensors monitoring Mac devices submit to clusters running OS X guest images.

To configure a preferred cluster:

Enable the CLI configuration mode:

appl-hostname > enable
appl-hostname # configure terminal

Unsubscribe the sensor or hybrid appliance from the cluster with which it is currently subscribed (if any):
```
appl-hostname (config) # mvx cluster unenroll now
```
Configure the preferred cluster.
```
appl-hostname (config) # mvx cluster enrollment-service preferred name<clusterName>
```
where <clusterName> is the name of the cluster to enroll the sensor with.

Verify your change:

appl-hostname (config) # show mvx cluster enrollment status

Save your change:
```
appl-hostname (config) # write memory
```

To remove the preferred cluster enrollment:

Remove the preferred cluster enrollment:

appl-hostname (config) # no mvx cluster enrollment-service preferred name

Verify your change:

appl-hostname (config) # show mvx cluster enrollment status

Save your change:
```
appl-hostname (config) # write memory
```
Note
The sensor or hybrid appliance will be automatically enrolled with the cluster with the most capacity after you remove the preferred cluster enrollment.

Example

The following example unsubscribes the nx-1 sensor from the cluster it is currently enrolled with, and then configures Cluster02 as its preferred cluster.

nx-1 (config) # mvx cluster unenroll now
nx-1 (config) # mvx cluster enrollment-service preferred name Cluster02
nx-1 (config) # show mvx cluster enrollment status
