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.

For SummitStack V-160 on the X770, ports 103 and 104 are the stacking ports.
