Software Packaging on the Cisco ASR 1000 Series Routers
A collection of software subpackages packaged together creates a single consolidated package. A
consolidated package allows users to upgrade all individual subpackages on the router with a single
software image download. Consolidated packages can be downloaded from Cisco.com; users who want
to run the router using individual subpackages that are part of the consolidated package must first
download the image from Cisco.com and extract the individual subpackages from the image, which can
be done by entering
request platform
command-line interface commands.
Beginning in Cisco IOS XE Release 2.4, support for a supplemental, optional subpackage of type called
sipspawma
is introduced to support the Cisco WebEx Node for ASR 1000 Series shared port adapter
(SPA). Optional subpackages are installed similarly to individual subpackages; however, optional
subpackages are not bundled as part of a consolidated package like prior support for the individual
subpackages, and optional subpackages must be downloaded independently.
See the
“Consolidated Packages” section on page 2
and
“Individual Software SubPackages Within a
Consolidated Package” section on page 1-3
of this book for additional information on extracting
individual subpackages from a consolidated package, supplemental optional subpackages, and other
information on managing software.
Consolidated Packages
A consolidated package is a single image composed of individual software subpackage files. A single
consolidated package file is a bootable file, and the Cisco ASR 1000 Series Router can be run using the
consolidated package.
Note
Consolidated packages only contain the required individual subpackage files. These packages do not
contain supplemental, optional subpackages, such as the “sipspawma” package for the Cisco WebEx
Node for ASR 1000 Series.
Each consolidated package also contains a provisioning file. A provisioning file is used for booting in
cases where the individual subpackages are extracted from the consolidated package, or optional
subpackages are used to run the router. For additional information on the advantages and disadvantages
of running a complete consolidated package, see the
“Running the Cisco ASR 1000 Series Routers: An
Overview” section on page 3-1
. For additional information on provisioning files, see the
“Provisioning
Files” section on page 1-4
.
For information about the consolidated packages available in a specific version of Cisco IOS XE, see the
release notes for that version of Cisco IOS XE. The
Cisco IOS XE Software Release Notes
contains the
release notes for each version of Cisco IOS XE.
Important Information About Consolidated Packages
The important information about consolidated packages include:
•
For each version of a consolidated package, the RPBase, RPControl, ESPBase, SIPSPA, and
SIPBase subpackages are identical among consolidated packages.
•
For each version of consolidated package, the RPIOS subpackage is always different among
consolidated packages.
•
A consolidated package file is a bootable file. If the router is configured to run using a the complete
consolidated package, boot the router using the consolidated package file. If the router is configured
to run using individual subpackages, boot the router using the provisioning file. For additional
