Huawei S Series Switches Stack Guide—Version and Model Requirements
As we know, switch stacking deployment has some special requirement or limitation, this blog will share the software version and model requirement in detail on Huawei S Series Switches stack deployment.
Licensing Requirements
Stacking is not under license control.
Version Requirements
Switches can set up a stack through stack card connection and service port connection based on stack port types. Service port connections are classified into ordinary and dedicated cable connections based on cable types.
- Ordinary cable connection: Switches use optical cables, network cables, and high-speed cables to set up a stack.
- Dedicated cable connection: Switches use dedicated stack cables to set up a stack. This connection mode is also called zero-configuration stacking.

Deployment Recommendations
- Connect a stack to other network devices using an Eth-Trunk and add one port of each member switch to the Eth-Trunk.
- When a stack connects to access devices, configure ports directly connected to terminals as STP edge ports to prevent STP re-calculation when the ports alternate between Up and Down states. This configuration ensures normal traffic forwarding.
- If storm control needs to be configured on many ports, replace storm control with traffic suppression to save CPU resources.
- If port security needs to be configured on many ports, replace port security with MAC address learning limiting to save CPU resources.
- Loops may occur on a network to which a stack connects. Run the mac-address flapping action error-down command to set an interface to the error-down state when MAC address flapping is detected on the interface. This improves system processing performance and allows the peer device to detect that the interface becomes Down. Additionally, if the peer device has redundant links, traffic can be rapidly switched to a normal link.
