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.
