Parameters

per-flow: Specifies the flow-based forwarding. The device forwards packets of a flow to the same CPU.

A data flow is defined by the following fields: source IP address, destination IP address, source port

number, destination port number, and protocol number. This policy takes the first-in first-out rule.

per-packet: Specifies the packet-based forwarding. The device forwards packets in sequence to different

CPUs, even though they are the same flow. This policy does not ensure packet order.

Examples

# Specify the packet-based policy.

<Sysname> system-view

[Sysname] forwarding policy per-packet

# Specify the flow-based policy.

<Sysname> system-view
