dynamic flow

Function

The dynamic flow command configures dynamic iFIT flow learning.

The reset dynamic flow command clears the learned iFIT dynamic flow.

By default, no dynamic flow is configured.

Usage Guidelines

Usage Scenario

To enable dynamic iFIT flow learning, run the dynamic flow command.

To clear the learned iFIT dynamic flow, run the reset dynamic flow command.

Prerequisites

The VPN instance address family has been configured, the interface has been bound to the VPN instance, and dynamic flows have been created.

Precautions

Per-packet delay measurement can be enabled only after packet loss measurement is enabled and is mutually exclusive with out-of-order packet measurement.
