About multi-CPU packet distribution
On a multi-CPU device, packets can be distributed among CPUs based on one of the following policies:
· Flow-based policy—Forwards packets of a flow to one CPU or multiple CPUs. The CPU processes flow packets by following the first-in first-out rule. The device supports using the source IP address, destination IP address, source port number, destination port number, and protocol number to identify a flow.
· Packet-based policy—Forwards packets in sequence to different CPUs, even though they are the same flow. This policy does not ensure packet order.

Restrictions and guidelines: Multi-CPU packet distribution configuration
If a service requires packets of a flow to be received by the same CPU, you must use the flow-based policy.
Specifying a packet distribution policy
1. Enter system view.
system-view
2. Specify a packet distribution policy.
forwarding policy { per-flow [ three-tuple | mode { source-ip | destination-ip | source-port | destination-port } ] | per-packet }
By default, the device uses the flow-based policy that identifies a flow by source IP address, destination IP address, source port number, destination port number, and protocol number.
