Configuring flow classification
To implement differentiated services, flow classification categorizes packets to be forwarded by a multicore device according to one of the following flow classification policies:
· Flow-based policy—Forwards packets of a flow to the same CPU. A data flow is defined by using 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.
· Packet-based policy—Forwards packets in sequence to different CPUs, even though they are the same flow. This policy does not ensure packet order.
Specifying a flow classification policy
|
|
IMPORTANT: If a service requires packets of a flow to be received by the same CPU, you must use the flow-based policy. |
To specify a global flow classification policy:
|
Step |
Command |
Remarks |
|
1. Enter system view. |

N/A |
|
2. Specify a flow classification policy. |
forwarding policy { per-flow | per-packet } |
By default, flow-based policy is used globally. |
