Using SummitStack-V160 Stacking
A stacking rate of 160 Gbps can be achieved using certain configurations of Summit switches. For
example, a Summit X670V (X670V-48x or X670V-48t) switch can be connected to a Summit X650 series
switch through 40-Gbps stacking connections that provide 160 Gbps full duplex bandwidth. This
connection is performed using the VIM4-40G4X module in the Summit X670V switch and the
VIM3-40G4X module in the Summit X650 series switch. V-160 stacking is also supported on the X480
series switch using the VIM3-40G4x module.
On the VIM4-40G4X module, ports S3 and S4 are the stacking ports.
Figure 151 shows a stack using Summit X670V, X650, X480, and X460 series switches.
Figure 151: Example SummitStack-V160 Configuration
Table 71 lists the recommended order for connecting the stacking ports in this example.
To connect a VIM3-40G4X or VIM4-40G4X stacking port to a stacking port on a VIM2-SummitStack-V80
or SummitStack-V80 module, you must set the VIM3 or VIM4 port to operate at the slower speed of the
SummitStack-V80 port. To do so, use the
configure stacking-support stack-ports selection
command. For more information about configuring stacking ports, see the ExtremeXOS Concepts Guide .
