Using the Extreme Stacking Tool

1. Open the Stacking Tool (https://stackingtool.extremenetworks.com/StackingTool/) in a web browser.
   

   Note

   The Stacking Tool is also available in the Support Tools section of the Extreme Portal.
2. Find a switch model in the Switches column.
   Each switch model is represented by a rectangle, as shown in the example in the following figure. In this example, stacking ports are represented by S1 and S2 on the right side.

   Tip

   Click a rectangle to display more information about the switch model and the VIMs (if any) that it can use for stacking.
3. Drag the rectangle to the first slot in the Stack column in the middle of the page.
   To the right of the Stack column, the tool displays statistics about available routes, supported software versions, and master/backup recommendations.

   Tip

   If you don't see statistics and other information, click the arrow (> symbol) to the immediate right of the Stack column.
4. Use the tool in any of the following ways:
   • Select other switches and drag them to the slots in the stacking column.
   • For any switch in the stack, click the S1 and S2 symbols to choose stacking methods – for example, SummitStack-V and SummitStack-V80 (supported in EXOS 30.1 and prior releases only).
   • To remove a switch from the stack, drag it away from the stacking column.

   Whenever you add or remove a switch from the stack, the statistics and recommendations update automatically.

In addition to statistics and recommendations, colors in the display show whether the selected switch models and stacking methods are compatible.
