Using Ethernet Ports for Stacking (SummitStack-V Feature)
On many Extreme Networks switches, you can reconfigure one or two 10-Gbps Ethernet data ports to
operate as stacking ports.
This feature, known as SummitStack-V or alternate stacking, means that you can use less expensive
cables to connect the switches in a stack. Because copper and fiber Ethernet ports support longer cable
