An administrator is attempting to enable Active-Active NIC load balancing on a cluster.

When configuring Link Aggregation Groups (LAG) or Active-Active NIC bonding (such as balance-tcp with LACP) on Nutanix AHV, there is a strict requirement regarding link negotiation. All interfaces in a bond must run at the same speed.

If the second node has physical NICs that have negotiated different speeds (e.g., one link at 10 Gbps and another at 1 Gbps due to a cabling issue or switch misconfiguration), the bond creation command will fail for that specific node. While identical hardware (Option A) is preferred, it is the actual operating speed of the links that determines whether the OVS bond can successfully form.
