Combining Switches from Different Series

Summit switches can be stacked in the combinations listed in Matrix of Switches and Stacking Methods. For each combination, one or more of the following stacking methods are displayed:
40G 40G mode
128G 128G mode (X480-24x switches with VIM2-SummitStack128)
SS SummitStack
V SummitStack-V
V80 SummitStack-V80
V84 SummitStack-V84 (X450-G2 switches)
V160 SummitStack-V160
V320 SummitStack-V320

Notes:
  1. X440-L2 models cannot be stacked.
  2. X460-G2 SummitStack-V is available only on 10G models.
  3. X450-G2 SummitStack-V is available only on 10G models. SummitStack-V84 is available only in stacks of Summit X450-G2 switches running the same version of ExtremeXOS.
  4. X670-G2-72x can stack only with SummitStack V using front panel 10G ports.
In a stack that has switch models from more than one Summit series, refer to the list in Master/Backup Switch Redundancy and follow these guidelines:
  • The stack master and backup nodes should be from the same switch series. For example, if a Summit X480 series switch is the stack master, the backup node should also be a Summit X480 series switch.
  • Follow these guidelines for the specific listed switch combinations:
    • If Summit X480 series and X650 switches are both present in the stack, the master and backup nodes should both be X480 switches.
    • If Summit X480 switches and X670 switches are both present in the stack, the master and backup nodes should both be X670 switches.
  • Although you can combine Summit X460, X480, and X670 switches in a stack, you should be aware that the routing table limit for the Summit X460 series is lower than the limits for the other two switch series. For more information, refer to the ExtremeXOS 16.2 User Guide.

Stack configuration, easy setup, and redundancy are fully described in the ExtremeXOS 16.2 User Guide.
