unconfigure switch

unconfigure switch {all | erase [all |nvram]}


Returns the switch configuration to its factory default settings and reboots the switch.

Syntax Description

all Specifies that the entire configuration should be changed to the default values, including the management IP address, failsafe account, and SummitStack-specific parameters, and the switch rebooted.
erase all All data such as loaded exos images(both partition), configuration files, policy files, non-volatile memory content and switch settings will be overwritten. This will render the switch inoperable until a bootrom rescue is performed. The system will reboot after the erase operation is complete which will take around 10 minutes.
erase nvram Data in non-volatile memory such as selected configuration, selection image partition, log messages will be overwritten. Switch will boot up with primary image. Any unsaved configuration changes will be lost and the switch will reboot.



Usage Guidelines

Use unconfigure switch to reset the configuration to factory defaults, but without erasing the configuration. This preserves users account information, date and time settings, SummitStack configuration, and so on.

Include the parameter all to clear the entire current configuration, including all switch and SummitStack parameters, and reboot using the last used image and factory default configuration.

The command unconfigure switch all does not clear licensing information. The license cannot be disabled once it is enabled on the switch.

For SummitStack only.

The all option also resets all stacking-specific parameters to defaults. To reset only the stacking-specific parameters to defaults, enter the unconfigure stacking command.

Beginning with ExtremeXOS 12.5, stacking support and stacking port selection are reset only on the local node. When stacking support of any kind is supported on the platform, the following message is added to the output that is shown on the console after this command has been confirmed:

 Stacking-support will be unconfigured on this node only. 


The following command preserves the entire current configuration (but does not reload the current configuration after the switch reboots) and reboots the switch or SummitStack using the last specified saved image and factory default configuration:

unconfigure switch all


This command was first available in ExtremeXOS 10.1.
