The stacking port selection option, which allows you to choose between native and alternate ports, is
enabled by default for X460-G2 switches. For more information, see Selecting Native and Alternate
Stacking Ports on page 206.

Native Stacking for X460-G2 Switches
X460-G2 1-gigabit switch models (GE4) support native stacking through an attached VIM-2ss or
VIM-2q module.
The VIM-2ss module permits stacking using the standard SummitStack cables.

The VIM-2q module connects to QSFP+ cables to form stacks using the SummitStack-V160 protocol.
