45.2.8 File Download Sequence

Whenever the Automatic Update feature is triggered (see ''Triggers for Automatic Update''
on page 783), the device attempts to download each file from the configured URLs, in the
following order:
1. ini file
2. CLI Script file
3. Periodic software file (.cmp) download
4. One-time software file (.cmp) download
5. Auxiliary file(s)
The following files automatically instruct the device to reset:

Periodic software file (.cmp)

One-time software file (.cmp)
When multiple files requiring a reset are downloaded, the device resets only after it has
downloaded and installed all the files. However, you can explicitly instruct the device to
immediately reset for the following files:

ini file: Use the ResetNow in file parameter

CLI Script file: Use the reload if-needed CLI command
Warning: If you use the ResetNow parameter in an ini file for periodic automatic
provisioning with non-HTTP (e.g., TFTP) and without CRC, the device resets after
every file download. Therefore, use the parameter with caution and only if necessary
for your deployment requirements.
Note:
•
For ini file downloads, by default, parameters not included in the file are set to
defaults. To retain the current settings of these parameters, set the
SetDefaultOnINIFileProcess parameter to 0.
•
If you have configured one-time software file (.cmp) download (configured by the
ini file parameter CmpFileURL or CLI command configure system > automatic-
update > firmware), the device will only apply the file if one-time software updates
are enabled. This is disabled by default to prevent unintentional software
upgrades. To enable one-time software upgrades, set the ini file parameter
AutoUpdateCmpFile to 1 or CLI command, configure system > automatic-update >
update-firmware on.
•
If you need to update the device's software and configuration, it is recommended
to first update the software. This is because the current ("old") software (before the
upgrade) may not be compatible with the new configuration. However, if both files
are available for download on the provisioning server(s), the device first
downloads and applies the new configuration, and only then does it download and
install the new software. Therefore, this is a very important issue to take into
consideration.
•
If more than one file needs to be updated - CLI Script and cmp: The device
downloads and applies the CLI Script file on the currently ("old") installed software
version. It then downloads and installs the cmp file with a reset. Therefore, the CLI
Script file MUST have configuration compatible with the "old" software version.
