This section lists all the caveats in NSX Advanced Load Balancer integration with NSX Multi-tenancy.

  • Only one NSX Cloud enabled with VPC mode is allowed per Avi Load Balancer cluster.

  • As of version 30.1.1 , only one Avi Load Balancer cluster with NSX Cloud enabled with VPC mode is allowed to provide load balancing for a single NSX Manager. That is, only 1:1 mapping of Avi Load Balancer and NSX Manager is allowed.

  • Currently, NSX Project and NSX VPC user and role mapping to Avi Load Balancer users and roles must be configured by the user.

  • Avi Load Balancer with VPC mode enabled might take around 20 minutes for the initial discovery in few scenarios. Also any new NSX VPC enabled withAvi Load Balancer might take 7-12 minutes for the discovery and provisioning before it is ready for consumption of load balancing.

  • VPC mode is immutable. The NSX Cloud configured with VPC mode cannot be deactivated.

  • Switching from static allocation to auto-allocate and vice versa of VS VIP is not supported.

  • By default, NSX will drop NS traffic due to the drop any firewall rule in VPC. You have to "Allow" catch-all E-W firewall rule in VPC or create a custom rule to allow needed traffic.

  • For deletion of NSX Cloud with VPC mode, you must clean up all the cloud resources (VS, Pool, Service Engines, Tenants, and more) before deletion of the cloud and deactivate the Avi Load Balancer flag for all respective NSX VPCs. The order of clean up is as follows:

    • Deactivate the Avi Load Balancer flag in all the NSX VPCs in the respective NSX Projects where its enabled.

    Delete the following:

    1. All the VS and Pools for the respective NSX VPCs.

    2. All the Service Engines for the respective tenants

    3. All the VRF and Network objects for the respective tenants

    4. All the data network configuration in the NSX Cloud

    5. Finally, delete the NSX Cloud with VPC mode enabled.

      Note:

      There is no auto-clean currently provided.

  • In NSX, if the Avi Load Balancer flag is enabled for the NSX VPC and the respective objects are in use in Avi Load Balancer (VS, Pool, and more) then the deactivate of the flag in NSX VPC will not have any effect (although you will be able to save the configuration). Avi Load Balancer will continue to allow LB configuration for the respective VPC admin.
