# Defining Global vCenter Attributes

To be able to create custom groups, you should first define global vCenter *Veeam.CustomTagN* attributes on the vCenter Server side. You can define the *Veeam.CustomTagN* attributes for different infrastructure objects, such as VMs, hosts, clusters, datastores, datastore clusters, virtual switches, resource pools and vApps.

You can add *Veeam.CustomTagN* attributes in different ways:

- You can create custom attributes manually, using vSphere Client. For more information, see the [VMware Online Documentation](https://techdocs.broadcom.com/).
- Also custom attributes can be created automatically by other 3^rd^-party applications.

Veeam MP for VMware captures *Veeam.CustomTagN* attributes and maps them to reserved object properties in OpsMgr. The following table provides a list of reserved object properties for different infrastructure objects:

<table style="width:80%;" class="Blue_Table">

    <th style="width:194px; height:22px;">
      <p>Custom Attributes / Reserved Properties</p>
    </th>
