Summit X460-G2 (1G Models Using VIM Ports) Stack Configuration Guidelines
Before deploying a new stack with Summit X460-G2 1-gigabit switch models (GE4), consider the
following guidelines:
•
SummitStack-V stacking is supported through an attached VIM: VIM-2x, VIM-2q, or VIM-2ss.
•
We recommend against mixing X450-G2, X460-G2, X770, and X670-G2 switches in a stack if the
desired routing table exceeds the supported limit.
•
Support is available on ExtremeXOS version 16.1 or later.
X590 Stacking
X590 series switches can be stacked with other X590 switches, with X690 switches, X695 switches, and
with X870 switches. X590 series switches support native stacking using front-panel data ports 29 and
33.
Alternate stacking is not supported for X590 switches.
The stacking-support option is disabled by default for all X590 switches. For more information, see
Enabling and Disabling the Stacking-Support Option on page 149.
Table 67 summarizes stacking support for X590 switches.
Note
Only QSFP28 direct-attach passive copper cable, at lengths up to 5 meters, can be used in
X590 stacking ports.

X620 Stacking
See X620 Stacking on page 63 for a full description of the X620 switch's stacking capabilities.
The stacking-support option is enabled by default for X620 switches. For more information, see
Enabling and Disabling the Stacking-Support Option on page 149.
The stacking port selection option, which allows you to choose between native and alternate ports, is
enabled by default for X620 switches. For more information, see Selecting Native and Alternate
Stacking Ports on page 162.
