Configuring Flow Recognition

To allow a device to send the septuple information (source and destination MAC addresses, source and destination IP addresses, source and destination port numbers, and protocol type) of traffic to a controller for flow identification, enable flow recognition.

Context

Figure 1 shows the typical networking of flow recognition. Target flows enter the transport network from the multimedia terminal and then reach the device through interface 1. After flow recognition is enabled on the device, the device collects data and then sends the data to the controller over telemetry.

Pre-configuration Tasks

Before configuring flow recognition, complete the following tasks:

Configure a dynamic routing protocol or static routes so that nodes are reachable at the network layer.
Configure static telemetry subscription to ensure that data is promptly reported to the controller.

Procedure

Run system-view
The system view is displayed.
Run interface interface-type interface-number
The interface view is displayed.
Run flow-recognition inbound
Flow recognition is enabled on the interface.
Run commit
The configuration is committed.
