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 161: Example SummitStack-V320 Configuration
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.
Using the VIM1-SummitStack512 Module
The VIM1-SummitStack512 versatile interface module allows you to connect two Summit X650 series
switches in a cross-over or back-to-back configuration, using SummitStack 128G cables.
This configuration provides two bidirectional links operating at 256 Gbps between the two switches.
Figure 162: Stacking Connections Using VIM1-SummitStack512 Modules and
SummitStack 128G Cables
Unlike other stacking configurations, with the VIM1-SummitStack512 modules, ports are connected in
pairs of matching port numbers. When you connect stacking cables to installed VIM1-SummitStack512
modules, match the stacking ports as listed in the following table.
