The statement is true. Stacking technology, such as Huawei's iStack, is designed to connect multiple physical switches so they function as a single logical device. This simplifies network management by providing a single management IP address, a unified configuration file, and a single forwarding plane for the entire stack. The number of switches that can be stacked depends on the specific switch model and software version, but it is designed to be more than two to provide scalability and high port density.

This is a true/false question. The statement is factually correct, so there are no incorrect options to evaluate.

1. Huawei CloudEngine S5735-L Series Switches Product Documentation, "Device Management Configuration Guide", Section: "iStack Configuration". This guide details how to configure iStack with multiple member switches (e.g., up to 9 for this series).

2. Huawei HCIA-Datacom V1.0 Training Material, "Ethernet Switching". The courseware describes stacking as a method to virtualize multiple switches into one logical device to expand port capacity and simplify management.
