VCF networking guidance emphasizes independent uplinks and notes that while LACP is supported, it is not recommended and introduces additional operational considerations. Specifically: ''Link aggregation to the host is supported but not recommended---the default switch-independent load-based teaming (LBT) provides benefits similar to those of LACP without added configuration complexity.'' It further states: ''Use of LACP... requires specific LACP configuration and switch setup... Not all vSphere features are supported with LACP... [and is] API only.'' The design recommendation is: ''Ensure each connection between the fabric switch and host operates as an independent uplink.''

Given the customer constraint that the VMware Administration team cannot re-configure the physical network, the prerequisite physical switch port-channel configuration for LACP cannot be performed. During bring-up and life-cycle operations, the Management Domain must follow VCF's standardized, automated patterns and therefore cannot rely on fabric changes the team cannot make. As a result, LAG cannot be used in the Management Domain, and the design must adopt independent uplinks (LBT) for management, vMotion, and VM traffic while using NFS as principal storage per the NFS Storage Model.
