Selecting Native and Alternate Stacking Ports

On switches that provide both native stacking ports and alternate stacking ports (described in Stacking Considerations for Each Switch Model), you can configure each logical stacking port to use either the native stacking port or the alternate stacking port. You can configure logical stacking ports to use any of the following physical stacking port configurations:
  • Two native stacking ports
  • Two alternate stacking ports
  • One native stacking port and one alternate stacking port

When the Stacking Port Selection Control option is enabled in a switch's configuration, you can choose between native and alternate stacking ports. The default selection is the native stacking ports.
