Build 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 either the front or the rear of
                    the switch.
 
            

Note   
Native stacking can be
                configured using Native-400 utilizing QSFP28 optics or
                Native-400-Alternative-Configuration using long range AOC optics.
 
 
When planning and building your stack, be sure to follow port
            compatibility and cabling recommendations as described in this chapter.
