Terraform

v1.5.7

Terraform Provider

v2.6.1

VMware vSphere

v7.0.3

Description

When configuring a Distributed Switch with LACP on a vSphere environment with "enhanced" Distributed Switches (LACP API version "multipleLag") LACP is not being configured and an error is thrown in vSphere stating that the LACP config is not compatible with API version "multipleLag".

The output from Terraform pasted below doesn't display the entire error and neither does the debug option. In vSphere the entire error is printed however: "The configurations of the objects are in conflict. Link Aggregation Control Protocol group configured on DSwitch1 conflicts with the Link Aggregation Control Protocol API version multipleLag.".
The error makes sense if the "multipleLag" API version doesn't understand the LACP options Terraform tries to configure. The "singleLag" API version ("basic" switches instead of "enhanced" switches) is unfortunately not available when creating Distributed Switches in VMware 7.

Panic Output

No response

Expected Behavior

Terraform should be able to configure LACP on an "enhanced" Distributed Switch which is the only version available in VMware 7.

Actual Behavior

LACP isn't configured because the LACP config isn't compatible with the Distributed Switches in vSphere 7.

Output from vSphere: "The configurations of the objects are in conflict. Link Aggregation Control Protocol group configured on DSwitch1 conflicts with the Link Aggregation Control Protocol API version multipleLag."

Steps to Reproduce

Configuring a Distributed Switch in vsphere 7 environment with the following options:

  lacp_api_version = "multipleLag"
  lacp_enabled     = true
  lacp_mode        = "active"
