A stack consists of a group of up to eight switches that are connected to form a ring. The stack offers the combined port capacity of the individual switches. But it operates as if it were a single switch, making network administration easier.
Stacking is facilitated by the SummitStack feature – part of the ExtremeXOS Edge license.
For descriptions of the supported configurations for stacking, considerations for planning a stack, and instructions for setting up the hardware, see the Stacking topic in the hardware installation guide for your switch. Also see the Configuring Stacked Switches topic in the user guide for your version of the switch operating system. We recommend that you read these topics before installing the switches that will make up the stack.
