Configuring the Device to Download Configuration Files

list information. If NVRAM contains a complete configuration file, the device prompts you to confirm your
overwrite of the complete version with the distilled version. If NVRAM contains a distilled configuration,
the device does not prompt you for confirmation and proceeds with overwriting the existing distilled
configuration file in NVRAM.
Note
If you specify a file in a flash device as the CONFIG_FILE environment variable, every time you save your
configuration file with the copy system:running-config nvram:startup-config command, the old
configuration file is marked as "deleted," and the new configuration file is saved to that device. Eventually,
Flash memory fills up as the old configuration files still take up memory. Use the squeeze EXEC command
to permanently delete the old configuration files and reclaim the space.
Configuring the Device to Download Configuration Files
You can specify an ordered list of network configuration and host configuration filenames. The Cisco IOS
XE software scans this list until it loads the appropriate network or host configuration file.
To configure the device to download configuration files at system startup, perform at least one of the tasks

If the device fails to load a configuration file during startup, it tries again every 10 minutes (the default setting)
until a host provides the requested files. With each failed attempt, the device displays the following message
on the console terminal:
Booting host-confg... [timed out]
If there are any problems with the startup configuration file, or if the configuration register is set to ignore
NVRAM, the device enters the Setup command facility.
