Modify the Boot Sequence

About this task

Modify the boot sequence to prevent the switch from using the factory default settings or, conversely, to prevent loading a saved configuration file.

1. Enter Global Configuration mode:

   enable

   configure terminal

2. Perform one of the following actions:

   • Bypass the loading of the switch configuration file and load the factory defaults:

     boot config flags factorydefaults [config-only | reset-all-files | zero-touch]

   • Use a configuration file and not the factory defaults:

     no boot config flags factorydefaults

     

     Important

     If the switch fails to read and load a saved configuration file after it starts, check the log file to see if the log file indicates that the factorydefaults setting was enabled, before you investigate other options.

Example

Modifying the boot sequence with an optional behavior of the factory default boot flag.

Switch:1>enable
Switch:1#configure terminal
Switch:1(config)#boot config flags factorydefaults
Switch:1(config)#boot config flags factorydefaults config-only
Warning: If you try to reset with a new image, it will not be loaded.
         To undo this operation use "no boot config flags factorydefaults"
