3.4 Configuring Local Flow Mirroring

To monitor and analyze the packets with same characteristics passing through the mirrored
interface that is located on the same AR3200 as the observing interface, configure local port
mirroring on the AR3200.

3.4.1 Establishing the Configuration Task

Before configuring local flow mirroring, familiarize yourself with the applicable environment,
complete the pre-configuration tasks, and obtain the required data. This will help you complete
the configuration task quickly and accurately.
Applicable Environment
An intranet has high requirements for information security and privacy protection. You can
configure mirroring on an interface to monitor incoming and outgoing data packets. The
management server that has the monitoring software installed can capture these packets for
analysis and fault location.
To monitor and analyze the packets with some characteristics passing through the mirrored
interface that is located on the same AR3200 as the observing interface, configure local port
mirroring on the AR3200.
Pre-configuration Tasks
None.
Data Preparation
To configure local flow mirroring, you need the following data.
No.

3.4.2 Configuring a Local Observing Interface

The local observing interface is used to export the packets copied from the mirrored interface.
Context
After an interface is configured as the observing interface, other configurations are not
recommended on the interface. Otherwise, the following situations may occur:
