Products

• VMware Cloud Director

Issue/Introduction

When connecting a VMware Advanced Loadbalancer or VMware AVI Load Balancer to VMware Cloud Director there are no errors. However, when the tenant is attempting to configure services for the ALB all services are greyed out despite standard or premium settings. There are no errors given in the UI.

Within the vcloud-container-debug.log the following error can be seen:

Environment

VMware Cloud Director 10.6.x
NSX 4.2.x
ALB 30.2.1

Cause

There are two possible causes: either the ALB version is incompatible with VMware Cloud Director, or the ALB is not configured as a HTTP load balancer.

Resolution

First ensure that the load balancer is configured as HTTP. If the issue persists please engage with Broadcom VCF support to ensure the interoperability is correct for the versions.
