Chapter 5: Building a SummitStack Configuration
Summit Family Switches Hardware Installation Guide

NOTE
SummitStack-V320 stacking can be mixed with V160, V80, and 10G alternate port stacking. For example,
a Summit X460 with SummitStack-V80 could be added to the sample stack in Figure 152. However, you must
restrict the speed of the ports on the VIM3-40G4X and VIM4-40G4X that connect to any ports on nodes operating
at slower speeds. To reduce the speed of ports on the VIM3-40G4X or VIM4-40G4X, use the configure
stacking-support stack-ports selection command. For more information about configuring stacking
ports, see the ExtremeXOS Concepts Guide.
