Introduction

The Cisco ASR 1000 Series Aggregation Services Routers are the next generation Cisco midrange router products. The Cisco ASR 1000 Series Aggregation Services Routers use an innovative and powerful hardware processor technology known as the Cisco QuantumFlow Processor. The Cisco ASR 1000 Series Routers consist of three different routers: the Cisco ASR 1002 Router, the Cisco ASR 1004 Router, and the Cisco ASR 1006 Router.

•The Cisco ASR 1002 Router is a 3-SPA, 2-rack-unit (RU) chassis with one Embedded Services Processor (ESP) slot that comes with the Route Processor (RP), Cisco ASR 1000 Series Shared Port Adapter Interface Processor (SIP), and four Gigabit Ethernet ports built in.

•The Cisco ASR 1004 Router is an 8-SPA, 4-RU chassis with one ESP slot, one RP slot, and two SIP slots.

•The Cisco ASR 1006 Router is a 12-SPA, 6-rack-unit (RU), hardware-redundant chassis with two Embedded Services Processor (ESP) slots, two Route Processor (RP) slots, and three SIP slots.

For the single-route-processor Cisco ASR 1000 platforms, the Cisco ASR 1002 and Cisco ASR 1004, the Route Processor has a dual Cisco IOS Software option that allows these routers to use Cisco IOS software redundancy, Cisco high-availability features, Nonstop Forwarding (NSF), and In Service Software Upgrades (ISSUs). This option requires the Cisco ASR 1000 Series Route Processor to have 4 GB of DRAM memory.

The Cisco ASR 1006 Router supports fully redundant Route Processors that allow for full Route-Processor hardware redundancy, NSF, ISSU, and future Route-Processor service upgrades.

The Cisco ASR 1000 Series Routers run Cisco IOS XE Software and introduce a distributed software architecture that moves many operating system responsibilities out of the IOS process. In this architecture, Cisco IOS, which previously was responsible for almost all of the internal software processes, now runs as one of many Cisco IOS XE processes while allowing other Cisco IOS XE processes to share responsibility for running the router.

One of the key features of the Cisco IOS XE Software is support for dual Cisco IOS software consolidated packages in a single Route Processor for software redundancy in the 2-RU and 4-RU chassis systems. These dual Cisco IOS consolidated packages can consist of the same software consolidated packages for backup or different software consolidated packages for resilient upgrade.

Note Software redundancy is not supported on the 6-RU chassis.

The Cisco ASR 1000 Series Routers target both enterprise and service provider applications and provide application-specific features for broadband subscriber aggregation and network application services with improved processing performance and high availability.

For information on new features and Cisco IOS commands supported by Cisco IOS XE Release 2, see the "New and Changed Information" section and the "Related Documentation" section.

System Requirements

This section describes the system requirements for Cisco IOS XE Release 2 and includes the following sections:

•Software Packaging on the Cisco ASR 1000 Series Routers

•Cisco IOS XE Software Package Compatibility for ISSU

•Cisco IOS XE Release Compatibility Tables

•RP Memory Recommendations

•Hardware Supported

•ROMmon Version Requirements

•Determining the Software Version

•Upgrading to a New Software Release

•Cisco IOS XE to Cisco IOS Version Number Mapping

Software Packaging on the Cisco ASR 1000 Series Routers

The Cisco ASR 1000 Series Routers run Cisco IOS XE Software and use a new software packaging model consisting of:

•Consolidated packages

•Individual software sub-packages within a consolidated package

•Optional software sub-packages outside of consolidated packages

Each Cisco IOS XE consolidated package contains a collection of individual software sub-packages. Each individual software sub-package is an individual software file that controls a different element or elements of the Cisco ASR 1000 Series Router. Some individual sub-packages may be installed per element (for example, per SPA).

Note The sub-package functionality is intended for both upgrade and field support, and not all combinations of sub-packages are supported.

Each individual software sub-package can be upgraded individually, or all individual software sub-packages for a specific Cisco IOS XE consolidated package can be upgraded as part of a complete Cisco IOS XE consolidated package upgrade.

Importantly, IOS (the RPIOS individual software sub-package) is considered one of the individual software sub-packages that makes up the complete Cisco IOS XE consolidated package.

The following are the individual software sub-packages within a consolidated package:

•Route Processor

–RPBase: Provides the Route-Processor operating system.

–RPControl: Provides the control-plane processes that interface between Cisco IOS Software and the rest of the platform.

–RPIOS: Provides the Cisco IOS Software kernel, which is where Cisco IOS Software features are stored and run; each consolidated image variant has a different RPIOS sub-package: RPIOS-ipbase, RPIOS-ipbasek9, RPIOS-advipservices, RPIOS-advipservicesk9, RPIOS-adventservices, and RPIOS-adventservicesk9.

Note The RPIOS-advipservices and RPIOS-adventservices sub-packages are only available beginning with Cisco IOS XE Release 2.2.1 and later releases. These two sub-packages are not available with Cisco IOS XE Release 2.1.2 and earlier releases.

–RPAccess: Provides components to manage enhanced router access functionality.

•ESP

–ESPBase: Provides the ESP operating system and control processes, and the Cisco QuantumFlow Processor client, driver, and ucode.

•SIP

–SIPBase: Provides the SIP operating system and control processes

–SIPSPA: Provides the SPA drivers and associated field-programmable device (FPD) image (SPA FPGA image)

A Cisco IOS XE consolidated package allows users to upgrade all individual software sub-packages on the router with a single Cisco IOS XE image download. The Cisco IOS XE consolidated packages available vary based on the Route Processor (RP1 or RP2) installed in the system and the Cisco IOS XE Release.

The following are the RP1 consolidated packages:

•Cisco ASR 1000 Series RP1 IP BASE W/O CRYPTO

•Cisco ASR 1000 Series RP1 IP BASE

•Cisco ASR 1000 Series RP1 ADVANCED IP SERVICES

•Cisco ASR 1000 Series RP1 ADVANCED IP SERVICES W/O CRYPTO

•Cisco ASR 1000 Series RP1 ADVANCED ENTERPRISE SERVICES

•Cisco ASR 1000 Series RP1 ADVANCED ENTERPRISE SERVICES W/O CRYPTO

Note The Cisco ASR 1000 Series RP1 ADVANCED IP SERVICES W/O CRYPTO consolidated package is only available with Cisco IOS XE Release 2.2.1 through Cisco IOS XE Release 2.3.x. This consolidated package is not available with any other Cisco IOS XE Releases.

The Cisco ASR 1000 Series RP1 ADVANCED ENTERPRISE SERVICES W/O CRYPTO consolidated package is only available beginning with Cisco IOS XE Release 2.2.1 and later releases. This consolidated package is not available with Cisco IOS XE Release 2.1.2 and earlier releases.

The following are the RP2 consolidated packages:

•Cisco ASR 1000 Series RP2 IP BASE W/O CRYPTO

•Cisco ASR 1000 Series RP2 IP BASE

•Cisco ASR 1000 Series RP2 ADVANCED IP SERVICES

•Cisco ASR 1000 Series RP2 ADVANCED IP SERVICES W/O CRYPTO

•Cisco ASR 1000 Series RP2 ADVANCED ENTERPRISE SERVICES

•Cisco ASR 1000 Series RP2 ADVANCED ENTERPRISE SERVICES W/O CRYPTO

Note The RP2 consolidated packages are only available beginning with Cisco IOS XE Release 2.3.0 and later releases. The RP2 consolidated packages are not available with Cisco IOS XE Release 2.2.3 and earlier releases.

The Cisco ASR 1000 Series RP2 ADVANCED IP SERVICES W/O CRYPTO consolidated package is only available with Cisco IOS XE Release 2.3.0 through Cisco IOS XE Release 2.3.x. This consolidated package is not available with any other Cisco IOS XE Releases.

The individual software sub-packages within the consolidated packages cannot be downloaded from Cisco.com; only the Cisco IOS XE consolidated packages and optional sub-packages can be downloaded from Cisco.com. Users who want to run the router using individual software sub-packages must first download the consolidated package from Cisco.com and extract the individual software sub-packages from the consolidated package.

In addition to the individual software sub-packages within a consolidated package, optional software sub-packages that are not part of a consolidated package are available. Optional software sub-packages are downloaded separately from Cisco.com and their installation is similar to the installation of an individual software sub-package using a provisioning file. The optional sub-package must be located in the same directory with the provisioning file and the other individual sub-package files. The optional software sub-packages available vary based on the Route Processor (RP) installed in the system: RP1 or RP2:

•For the RP1, the optional software sub-package available is the Cisco ASR 1000 Series RP1 WebEx Node (asr1000rp1-sipspawmak9.version.pkg)

•For the RP2, the optional software sub-package available is the Cisco ASR 1000 Series RP2 WebEx Node (asr1000rp2-sipspawmak9.version.pkg)

Note The Cisco ASR 1000 Series RP1 WebEx Node and Cisco ASR 1000 Series RP2 WebEx Node optional software sub-packages are only available beginning with Cisco IOS XE Release 2.4.0 and later releases and are only supported in conjunction with a related RP-based Cisco ASR 1000 Series RPx IP BASE, Cisco ASR 1000 Series RPx ADVANCED IP SERVICES, or Cisco ASR 1000 Series RPx ADVANCED ENTERPRISE SERVICES consolidated package. These optional software sub-packages are not supported with earlier Cisco IOS XE releases or with any of the non-CRYPTO consolidated packages.

Note ISSU operation on the Cisco ASR 1002 and Cisco ASR 1004 systems requires the system to be operating in sub-package mode.

Note USB (or any other removable media) cannot be used to boot the system into sub-package mode.

For further information on the advantages and disadvantages of running individual sub-packages or a complete Cisco IOS XE consolidated package, and the process of extracting the individual sub-packages, see the following document:

Cisco IOS XE Software Package Compatibility for ISSU

When upgrading the Cisco IOS XE operating system software using the In Service Software Upgrade (ISSU) process, it is important to determine the compatibility of the upgraded software to your current software and hardware. The ISSU process allows software to be updated or otherwise modified while packet forwarding continues with minimal interruption.

Cisco IOS XE release compatibility using the ISSU process utilizes the SSO functionality to preserve state while software versions on the router differ, as during an upgrade. Most SSO-capable features in each Cisco IOS XE release are ISSU capable. ISSU is only supported if SSO is enabled in the configuration and the system is in a steady state (SSO ready state has been achieved). ISSU compatibility depends on the set of specific feature clients that are in use and whether they support ISSU. All ISSU upgrades include at least one IOS switchover operation. It is important to understand which features are in use and whether these features are ISSU compatible.

The Cisco ASR1006 Series Router is a hardware-redundant chassis. The hardware-redundant chassis has two ESP linecards and two RPs which exchange state using hardware links. The Cisco ASR1002 and ASR1004 Series Routers are not hardware redundant, but are software-redundancy capable. The non-redundant chassis has a single RP and a single ESP, but allows the operation of up to two IOS processes on the single RP to exchange states locally.

•Non-hardware-redundant chassis models (such as the Cisco ASR 1002 Router and Cisco ASR 1004 Router)—Supports ISSU only if the router is running in subpackage mode.

•Hardware-redundant chassis models (such as the Cisco ASR 1006 Router)—Supports ISSU when the router is running in sub-package mode or in consolidated package mode.

For a complete discussion about the ISSU upgrade process on the Cisco ASR 1000 Series Routers, including prerequisites and restrictions, see the "In Service Software Upgrade (ISSU)" chapter of the Cisco ASR 1000 Series Aggregation Services Software Configuration Guide.

Compatibility Support Policy

Rebuilds of a specific Cisco IOS XE release are intended to be fully ISSU and SSO capable for supported features between any two image pairings, however compatibility is not guaranteed for all releases. It is expected that rebuilds between release versions are compatible within a reasonable time frame.

Support for Cisco IOS XE Rebuilds

The support policy for version rebuilds is as follows:

•The immediate prior rebuild for the version is expected to be SSO and ISSU compatible with a new released rebuild of that version.

•A newly released rebuild is expected to be SSO and ISSU compatible with the current rebuild for the previous two versions.

As an example, a rebuild Y of version X is version XY. For rebuilds on the two previous versions of X, X-1 and X-2, it is expected that XY will be compatible with those versions.

Support for Special Cisco IOS XE Releases

Certain special Cisco IOS XE software releases may be made from time to time. These releases are not specified in this document and any supported SSO or ISSU interoperability must be determined on a case by case basis.

Cisco IOS XE Release Compatibility Tables

The ISSU compatibility tables in this section provide information about release pairs that are compatible and those that are not compatible for Cisco ASR1000 Series Routers. You can use this information to determine the impact of a Route Processor (RP) or Embedded Service Processor (ESP) switchover when the router is running a mixed combination of software as occurs during the whole-node ISSU procedures.

Non-SSO-capable features and non-ISSU-capable features are not included in the ISSU compatibility tables since these features lose state on any Cisco IOS XE switchover—RP switchover in the case of hardware-redundant chassis and software switchover on software-redundant chassis.

Discussion of Table Fields

In the ISSU compatibility tables, the following information is provided:

•SSO

A Cisco IOS XE release stating :SSO" for all supported SSO-capable features is fully compatible for upgrades using ISSU, even if some of the SSO-capable features are not ISSU capable. Two different versions of the software are denoted as supporting SSO if they are able to reach an SSO state when run simultaneously, regardless of the impact on specific features.

•SSO Tested

A Cisco IOS XE release stating "SSO Tested" indicates that the two releases are fully tested and supported as interoperable and will retain state across a switchover. ISSU upgrades between the releases are supported.

•SSO via <release>

A Cisco IOS XE release stating "SSO via <release>" indicates that the two releases are not interoperable and must not be run simultaneously (must not be run at the same time on the two RPs of a hardware redundant chassis and must not be co-installed as subpackages on any chassis). However, an SSO path exists using the intermediate release that is specified.

•Limited

A Cisco IOS XE release stating "Limited" indicates that the two releases have interoperability limitations. On the Cisco ASR1002 and Cisco ASR1004 routers. ISSU upgrade and downgrade are not supported. Instead you can perform a sub-package software upgrade. This process requires a RP reload.

The tables in the following sections list the compatibility of Cisco IOS XE software releases:

•ISSU Compatibility for Cisco IOS XE 2.1-Based Releases

•ISSU Compatibility for Cisco IOS XE 2.2-Based Releases

•ISSU Compatibility for Cisco IOS XE 2.3-Based Releases

•ISSU Compatibility for Cisco IOS XE 2.4-Based Releases

•ISSU Compatibility for Cisco IOS XE 2.5-Based Releases

•ISSU Compatibility for Cisco IOS XE 2.6-Based Releases

Note The ISSU compatibility tables use the following conventions:

•The software version numbers are given first as the Cisco IOS XE release version number followed by the bundled Cisco IOS release number.

•For descriptions of the table fields, see the "Discussion of Table Fields" section.

Caution For upgrading deployed releases prior to Cisco IOS XE 2.1.2, refer to the appropriate configuration guide. Some adjustments to the configuration procedure may be necessary due to changes in the installation command syntax. See Cisco IOS XE Software Configuration Guides .

Cisco IOS XE to Cisco IOS Version Number Mapping

Each version of Cisco IOS XE has an associated Cisco IOS version. Table 12 lists these mappings for all released versions of Cisco IOS XE.

Note The Cisco IOS XE 2.3.0 and Cisco IOS XE 2.3.1 images are no longer downloadable from Cisco.com. Replacement images (Cisco IOS XE 2.3.0t and Cisco IOS XE 2.3.1t) with exactly the same content and bug fixes are available on Cisco.com. If the Cisco IOS XE 2.3.0 and Cisco IOS XE 2.3.1 images are not causing any issues, no action is necessary. Old image MD5 sums will still be available for verification on the download page. For more details, see CSCsz80074.

Upgrading to a New Software Release

Only Cisco IOS XE consolidated packages can be downloaded from Cisco.com; users who want to run the router using individual sub-packages must first download the image from Cisco.com and extract the individual sub-packages from the consolidated package.

For information about upgrading to a new software release, see the following document:

Cisco ASR 1000 Series Aggregation Services Router Software Configuration Guide at the following location:
