Building Stacks

A stack consists of a group of up to four 220 series switches that are connected to form a logical 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.

This chapter describes the ways in which you can set up stacks, the things to consideration when planning stacks, and the steps for setting up the hardware. We recommend that you read this chapter before installing the switches that will make up the stack.

For information about configuring stacks and managing them on a day-to-day basis, see ExtremeSwitching 200 Series: Administration Guide.
