Choosing Between Native and Alternate
Stacking Ports
The dedicated stacking ports (either fixed or on installed VIMs or stacking modules) are called native
stacking ports. The SummitStack-V feature allows you to reconfigure one or two 10-Gbps Ethernet data
ports as stacking ports. When these ports are enabled to support stacking, they are called alternate
stacking ports. This feature allows you to use less expensive cables to connect the switches in a stack.
Because copper and fiber Ethernet ports support longer cable distances, this feature also allows you to
extend the physical distance between stack nodes. This feature supports stack nodes on different floors
in a building or in different buildings on a campus.
