Module
Using SummitStack-V160 Stacking
A stacking rate of 160 Gbps can be achieved using certain configurations of Extreme Networks
switches. For example, an X460-G2 switch can be connected to an X670-G2-48x-4q switch through
40-Gbps stacking connections that provide 160 Gbps full-duplex bandwidth. This connection is
performed using the VIM-2q module in the X460-G2 switch and the QSFP+ ports on the X670-
G2-48x-4q switch. V-160 stacking is also supported on the X770 switch using the QSFP+ ports.

40-Gbps stacking connections that provide 160 Gbps full-duplex bandwidth. This connection is
performed using the VIM4-2q module in the X460-G2 switch and the QSFP+ ports on the X670-
G2-48x-4q switch. V-160 stacking is also supported on the X480 series switch using the VIM3-40G4x
module, and on the X770 switch using the QSFP+ ports.
On the VIM4-40G4X module, ports S3 and S4 are the stacking ports.
Figure 218 shows an example stack using X670, X650, X480, and X460 series switches.
