Cisco IOS Releases and Images for the CiscouBR10012Router
Upgrading to a New Software Release
An upgrade is an order placed for a Cisco IOS® feature set that contains more functionality than the one
that you are replacing. And upgrade is not an update. An update consists of installing a more recent
version of the SAME feature set. Exception— If a feature set has been made obsolete, the next, closest
feature set, on a more recent release, will be considered an update.
For general information about upgrading to a new software release, refer to the Cisco IOS Upgrade Ordering
Instructions on Cisco.com.
12.3 BC Release Train and Images
The 12.3 Release Train is the first Cisco IOS Release to support the Performance Routing Engine 2
(PRE2) modules on the Cisco uBR10012 universal broadband router. This release adds a substantial
number of additional features while continuing to support earlier supported features from the 12.2
Release Train. These features are introduced in the “Supported Software Features for the
CiscouBR10012 Router” section on page10, with additional links for configuration documentation.
Table1 displays the memory recommendations of the CiscoIOS feature sets for the CiscouBR10012
universal broadband router for CiscoIOS Release 12.3(9a)BC.
12.2 BC Release Train and Images
The 12.2 BC train is an interim release train that provides DOCSIS 1.1 two-way support, along with
support for selected new features.
Cisco IOS Release 12.2(4)BC1b, provides a migration path from the earlier 12.2 XF releases. Cisco IOS
Release 12.2(4)BC1b supports the Cisco uBR10012 universal broadband router, which provides a
high-capacity, high-throughput cable modem termination system (CMTS), optimized for aggregating traffic
at the edge of the cable network. Designed for cable operators and service providers, the platform connects
residential subscribers via cable modems, digital set-top boxes, or IP telephony cable modems for high-speed
data, broadband entertainment, and IP telephony solutions.
Note Cisco IOS Release 12.2(4)BC1b does not include support for telco-return images.
