Building Basic Stacks
A stack can be created in either of two ways:
                - In native stacking, switches are connected
                    using either designated Ethernet data ports or dedicated stacking
                    connectors.
 
                - In alternate stacking, switches are connected
                    using 10-Gbps Ethernet data ports that have been configured for stacking. These
                    ports are located either on the switch itself or on option cards installed on
                    the rear of the switch.
 
            
         
When planning and building your stack, be sure to follow port
            compatibility and cabling recommendations as described in this chapter.
See Combining Switches from Different Series for
            information about which switch series can be combined to form a stack.
