Explanation
The Validate-DCB cmdlet is specifically designed to validate Data Center Bridging (DCB) configuration, which is a prerequisite for RDMA over Converged Ethernet (RoCE). When using Switch Embedded Teaming (SET), DCB must be correctly configured to support RDMA traffic. The Validate-DCB cmdlet checks that QoS policies, flow control, and RDMA settings are all properly configured according to Microsoft's requirements. Server Manager and Failover Cluster Manager lack this specific network validation capability, and Get-NetAdapter only retrieves adapter properties without performing DCB/RDMA validation.
