Using SummitStack-V320 Stacking

A stacking rate of 320 Gbps can be achieved across a stack of X670-G2-48x-4q and X770 switches using the QSFP+ connection and cables. These switches can use 80-Gbps stacking connections that provide 320 Gbps full-duplex bandwidth.

Physical Port Pairings for Front Panel Ports lists the port pairings for SummitStack V-320 using the front panel ports on the Summit X770 switch.
