Configuring Port Mirroring; Figure 3-5 Port Mirroring Principle - Zte ZXR10 5900E Series Configuration Manual

As shown in
traffic of port 1 can be monitored by port 3. This is called local mirroring. If the traffic of port
1 of switch 1 is mirrored to port 3 of switch 2, this process is called remote mirroring. For
remote mirroring, router 1 and switch 2 even can belong to the different public networks.

Port mirroring also provides backup tunnel for network transmission. As shown in
3-5, the data transmitted by port 1 is also transmitted by port 3 at the same time. In this
way, even if port 1 has failure, the data of port 3 is available.
