What's the load-balancing mechanism on nexus platform?

[guobwang]

For example, there're 2 route entries in my routing table with the same cost on Nexus 7K, what's the behavior of the device to deal with the packets? It's per-destination or per-packet load balancing?

Is there a command I can show and modify the load-balancing method, like "show ip cef 1.1.1.0" or "ip load-sharing per-packet/destination"?

Per flow / per-destination is the default. Per-packet load balancing can be configured on a per-input-interface level.

"show ip interface" will show the interface load balancing method.

"show ip load-sharing" in the admin context will show the current chassis behavior.
