X440-G2 Stacking
The stacking-support option is not enabled by default for X440-G2 10G switch models. For more
information, see Enabling and Disabling the Stacking-Support Option on page 192.
The stacking port selection option, which allows you to choose between native and alternate ports, is
enabled by default for X440-G2 10G switch models. For more information, see Selecting Native and
Alternate Stacking Ports on page 206.

Alternate stacking support is available on all X440-G2 10-gigabit models (10GE4) using two SFP+ ports,
when the switch has been enabled for stacking (enable stacking-support command). 10G
upgrade licensing is not required to enable stacking on the designated stack ports. Table 80
