Explanation
Multi-Chassis EtherChannel (MEC), used in technologies like Cisco VSS and vPC, supports two specialized hashing distribution algorithms: 'fixed' and 'adaptive'. Fixed distribution uses a deterministic hashing algorithm to assign flows to specific member links consistently. Adaptive distribution dynamically adjusts flow assignment based on link utilization to balance traffic more evenly across the bundle. Standard per-flow methods like src-dst-mac and src-dst-ip are single-chassis EtherChannel load-balancing methods, not the MEC-specific distribution algorithms. Round-robin is not a valid MEC distribution option.
