Create Dynamic Address Group Membership Criteria

In NSX-T, you can configure the membership criteria for your virtual machines and IP set belonging to an NSX-T security group (dynamic address group) in the Panorama plugin for NSX. For each dynamic address group, you must specify a service definition and define up to five match criteria and each criterion includes up to five match rules.
You create this membership criteria on the plugin and then push it to NSX-T Manager. However, this does not apply the membership criteria to guest virtual machines in your deployment. You must define and apply membership data, such as tags, to your guest VMs in NSX-T Manager.
The rules that the Panorama plugin for NSX-T identifies and classifies virtual machines based on two membership types—Virtual Machine or IP set. The keys and operators usable with each member type are listed in the table below.

  • Ends With
  • Not Equals (

Membership criteria changes should be made only on Panorama; do not make changes on NSX-T Manager. If you make changes on NSX-T Manager, the Panorama plugin for VMware NSX show the service definition as out-of-sync. You should click on the
Out-of-Sync
link to see the specific reason for the out-of-sync status. If a membership criteria change is the cause, perform a configuration sync by clicking
NSX-T Config-Sync

      To view the tags and scope, use the Panorama CLI (with NSX-T Manager 3.0.0 and later).
