Cisco FabricPath switches support ECMP forwarding for known unicast frames. If the destination switch ID can be reached through more than one output interface with equal cost, the forwarding engine uses a hash function to pick one of the interfaces. Which three options are valid for hash input for unicast frames? (Choose three.)
A. Use only the source parameters (layer-3, layer-4, or mixed).
B. Use the FabricPath switch ID in the FabricPath header.
C. Use only the destination parameters (layer-3, layer-4, or mixed).
D. Use both the source and the destination parameters (layer-3, layer-4, or mixed).
E. Include only Layer 2 input (source or destination MAC address).
