Overview
The device supports two IP forwarding modes: flow-based and packet-based.
• Flow-based forwarding—Forwards flows with the same 5 fields (source IP address, destination IP
address, source port number, destination port number, and protocol number) to the same CPU for
processing. This mode takes the first-in first-out rule. It is more suitable for traffic with strict
requirements of packet order such as audio and video.
• Packet-based forwarding—Forwards packets in sequence to different CPUs for processing, even
though they are the same flow. This mode does not ensure packet order.
Configuration procedure
To configure an IP forwarding mode:
Step Command Remarks
1. Enter system view. system-view N/A
2. Specify an IP forwarding
mode. ip forwarding { per-flow |
per-packet }
By default, the packet-based mode is used.
To make the IP forwarding mode
modification take effect, reboot the device.
