Each ExtremeSwitching and Summit switch model can use various methods of stacking.
Summit Stacking by Stacking Method shows the switch models that can participate in each stacking method.

SummitStack-V320 | 80 Gbps | 0.5 m - 100 m QSFP+ only |
Summit X670-G2-48x-4q (ports 49, 53, 57, 61) |
SummitStack-V400 | 100 Gbps | 0.5 m - 100 m QSFP28 only |
ExtremeSwitching X690 (ports 61,69) ExtremeSwitching X870 (ports 121,125) |
For more details about the stacking methods that are available for each switch series, see the ExtremeSwitching and Summit Switches: Hardware Installation Guide for Switches Using ExtremeXOS 21.1 or Later.
Note
Because all switches in the stack must run the same version of ExtremeXOS, it is not possible to stack switches that require ExtremeXOS version 21, for example the X440-G2 and the X620, with switches that are incompatible with ExtremeXOS version 21, for example the X440 and the X460.
