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.
Table 83 lists the port pairings for SummitStack V-320 using the front panel ports on the Summit X770
switch.

Examples of Valid Stacking Configurations
The X460-G2 accommodates the VIM-2ss SummitStack module, which provides SummitStack ports.
The examples in the following sections show various physical stacking arrangements: all switches in a
single rack, switches in two adjacent racks, and switches at the tops of several racks in a row.
Example: Basic Stack with Four Switches
This example shows a stack of four switches in a single rack.
The slot numbers presume a console connection to the switch at the top of the physical stack.
Figure 126 shows cable connections for a 4-node stack using SummitStack 40G cables to connect
switches with integrated SummitStack ports.

SummitStack Ports
Table 84 lists the recommended order for connecting the stacking ports in this example.
