If link aggregation is failing to pass traffic and is only showing a status of "configured," the most likely cause is a failed negotiation due to a misconfiguration on the Top-of-Rack (ToR) switches. This typically occurs when the aggregation protocols (like LACP) or the settings on the ToR switches do not match the configuration on the hosts. Ensuring that both ends of the aggregated links are configured identically and properly for the expected protocols is critical for successful link aggregation.References: Nutanix Network Configuration Guide, Best Practices for Network Aggregation.

When deploying Nutanix hardware, it is essential to ensure that all necessary components are included in the Bill of Materials (BOM). In this case, the BOM includes SFP+ modules but lacks the fiber cables needed for connectivity. The SFP+ modules indicate a requirement for fiber optic cables, and it's crucial for the consultant to ensure the client understands their responsibility to procure compatible cables. Nutanix typically does not provide fiber cables as these are considered network infrastructure components, which vary based on specific network requirements and setups.References:
