X460-G2 Stacking
The stacking-support option is enabled by default for X460-G2 switches. For more information, see Enabling and Disabling the Stacking-Support Option.
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.

10 Gbps | 0.5m–40km SFP+ |
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.

| 1 = LEDs | 2= QSFP+ ports |
Note
VIMs are not hot swappable. You must power down the switch before installing any VIMs.Alternate Stacking for X460-G2 Switches
X460-G2 10-gigabit switch models (10GE4) support alternate stacking (SummitStack-V feature) through the 10G SFP+ ports located on the front panel. See Summit X460-G2 (10G Models) Stack Configuration Guidelines for additional considerations.
X460-G2 1-gigabit switch models (GE4) support alternate stacking through an attached VIM-2x module. See Summit X460-G2 (1G Models Using VIM Ports) Stack Configuration Guidelines for additional considerations.
Note
40G ports on the VIM-2q cannot be partitioned into four 10G ports.Alternate Stacking Ports for X460-G2 Switches summarizes alternate stacking support for X460-G2 switches.
When the stacking-support option is enabled (with the enable stacking-support command), data communication stops on the physical data ports that are designated for alternate stacking. Then, when stacking is enabled (with the enable stacking command), those ports – listed in the Alternate Stacking Ports column of Alternate Stacking Ports for X460-G2 Switches – operate using the stacking protocol for the logical stacking ports.
| Switch Model | Type or location of Native Stacking Ports | Alternate Stacking Ports | Location of Alternate Stacking Ports |
|---|---|---|---|
| X460-G2-24t-GE4 X460-G2-24p-GE4 |
VIM-2ss or VIM-2q | 33,34 | VIM-2x |
| X460-G2-48t-GE4 X460-G2-48p-GE4 |
VIM-2ss or VIM-2q | 53,54 | VIM-2x |
| X460-G2-24t-10GE4 X460-G2-24x-10GE4 X460-G2-24p-10GE4 |
VIM-2ss or VIM-2q | 31,32 | Front panel |
| X460-G2-48t-10GE4 X460-G2-48x-10GE4 X460-G2-48p-10GE4 |
VIM-2ss or VIM-2q | 51,52 | Front panel |
Note
- On X460-G2 24-port 10GE4 switches, ports 31 and 32 are not available as data ports when the alternate stacking ports are used.
- On X460-G2 48-port 10GE4 switches, ports 51 and 52 are not available as data ports when the alternate stacking ports are used.
Additional Stacking Considerations for X460-G2 Switches
- When using the VIM-2ss module, you can enable stacking without enabling stacking-support because the ports are native to the switch. All other VIMs require stacking-support to be enabled.
- The X460-G2 switch has “protocol enhanced” set by default. (Older switches, such as the X460, have “protocol standard” set by default. When you add a switch to a stack, make sure the new switch has "protocol enhanced" set so that it can communicate with the X460-G2 switch and the other switches in the stack.)
