Important Notes About Provisioning Files
The important information about provisioning files include:
Each consolidated package contains two provisioning files. One of the provisioning files is always
named “packages.conf”, while the other provisioning file will have a name based on the
consolidated package naming structure. In any consolidated package, both provisioning files
perform the exact same function.
In most cases, the “packages.conf” provisioning file should be used to boot the router. Configuring
the router to boot using this file is generally easier because the router can be configured to boot using
“packages.conf”, so no changes have to be made to the boot statement when Cisco IOS XE is
upgraded (the boot system file-system:packages.conf configuration command can remain
unmodified before and after an upgrade).
The provisioning file and individual subpackage files must be kept in the same directory. The
provisioning file does not work properly if the individual subpackage files are in other directories.
The provisioning filename can be renamed; the individual subpackage filenames cannot be renamed.
After placing the provisioning file and the individual subpackage files in a directory and booting the
router, it is highly advisable not to rename, delete, or alter any of these files. Renaming, deleting, or
altering the files can lead to unpredictable router problems and behaviors.
ROMmon Image
An independent ROMmon image is released periodically separate from consolidated packages or any
other software releases.
See the documentation that accompanies the ROMmon image for information on each ROMmon image.
For additional information on ROMmon, see the Cisco ASR 1000 Series Routers Maintain and Operate
Guide.
File to Upgrade Field Programmable Hardware Devices
Starting in Cisco IOS XE Release 3.1.0S, a hardware programmable package file used to upgrade field
programmable hardware devices is released as needed. A package file is provided for the field
programmable device to customers in cases where a field upgrade is required. If the Cisco ASR 1000
Series Router contains an incompatible version of the hardware programmable firmware on the Cisco
ASR1000-RP, Cisco ASR1000-SIP, or Cisco ASR1000-ESP, then that firmware may need to be
upgraded.
Generally an upgrade is only necessary in cases where a system message indicates one of the field
programmable devices on the Cisco ASR 1000 Series Router needs an upgrade or a Cisco technical
support representative suggests an upgrade.
In Cisco IOS XE Release 3.1.0S, a package file that contains a new version of the Complex
Programmable Logic Device (CPLD) code is available for users who need to upgrade old versions of
firmware on a Cisco ASR1000-RP2 or Cisco ASR1000-SIP10 in a Cisco ASR 1013 Router.
For more information on upgrading field programmable hardware devices, see the Upgrading Field
Programmable Hardware Devices for Cisco ASR 1000 Series Routers document.
