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:

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


This command was first available in ExtremeXOS 12.2.

Support for the Summit X480 switch configurations listed in the “Usage Guidelines” section was added in ExtremeXOS 12.5.

Platform Availability

This command is available only on Summit X480, X670, and X770 switches.
