Reminder to myself.
As mentioned prior, it’s important to note enhancements listed here are applicable primarily for Active/Standby use cases such as DR. The reason for this is the local NSX Manager does not have visibility into the inventory of the other NSX Managers’ vCenters. Thus, when a security rule is utilized with the Universal Security Groups leveraging the new supported matching criteria of VM Name or Universal Security Tag in the source/destination fields, since the translation of the security group happens locally, only the VMs/workloads in the local vCenter will be found as members of the security group.
Thus, when leveraging Universal Security Groups with the new supported matching criteria, the entire application must be at the same site as shown below in Figure 11. For example, if the application is spanning across sites and there is Cross-VC traffic flows, the security policy for the application will not provide the desired results.
