Configuring Flow Classification; Specifying A Flow Classification Policy - H3C MSR 2600 Configuration Manual

Configuring flow classification

The following matrix shows the feature and router compatibility:
Feature
Flow classification
To implement differentiated services, flow classification categorizes packets to be forwarded by a
multi-core 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 the packets of a flow must be received by the same CPU, use the flow-based policy.
To specify a flow classification policy:
Step
1. Enter system view.
2. Specify a flow classification
policy.
