→ Verification that the physical characteristics, such as speed and auto-negotiation is
configured and initiates operator notifications (traps) if errors exist. Consistency of
MC-LAG configuration (system-id, administrative-key and system-priority) is
provided. Similarly, load-balancing mode of operation must be consistently
configured on both nodes.
