Usage Information
Restoring factory defaults deletes the existing startup configuration and all persistent settings (stacking, fan-out,
and so forth).
When restoring all units in a stack, all the units in the stack are placed into stand-alone mode.
When restoring a single unit in a stack, that unit placed in stand-alone mode. No other units in the stack are
affected.
When restoring units in stand-alone mode, the units remain in stand-alone mode after the restoration. After the
restore is complete, the units power cycle immediately.
CAUTION: There is no undo for this command.
Following are the factory-default environment variables:
• baudrate
• primary_boot
• secondary_boot
• default_boot
• ipaddr
• gatewayip
• netmask
• macaddr
• mgmtautoneg
• mgmtspeed100
• mgmtfullduplex
Each boot path variable (primary_boot, secondary_boot, and default_boot) is further split into the following three
independent variables:
• primary_server, primary_file, and primary_type
• secondary_server, secondary_file, and secondary_type
• default_server, default_file, and default_type
NOTE:
For information on the default values that these variables take, refer to the Restoring
Factory Default Environment Variables section in the Dell EMC Networking OS Configuration
guide.
