enable stacking-support

enable stacking-support


This command enables a Summit switch with dual-purpose hardware to participate in a stack.

Syntax Description

This command does not have additional syntax.


Stacking support is enabled by default for all platforms, except the Summit X440-G2 and ExtremeSwitching X870.

Usage Guidelines

The Stacking-Support Option Control column in Summit Family Switch Support for Alternate Stack Ports displays Yes in the rows for switch configurations for which you can enable the stacking-support option.

After you enable the stacking-support option, you must reboot the switch to activate the configuration change.

If you enable the stacking-support option on a switch and reboot, data communications on the data ports listed in Summit Family Switch Support for Alternate Stack Ports stops, and the ports use stacking protocols instead of Ethernet protocols.


To enable the stack ports, enter the following command:

# enable stacking-support
This setting will take effect at the next reboot of this switch.


This command was first available in ExtremeXOS 12.2.
