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.
