There is currently no replacement product available for this product. Upgrade from 2. Note that SMUs have slightly different naming conventions because they are designed to be release-specific, platform-specific patches. The key differences are the file format and an additional value that indicates which bug an SMU addresses. SMUs are released as software maintenance upgrade. This ID is inserted between the release and architecture values in the filename.


Cisco NX-OS Software is a data-center-class operating system that provides high availability with a modular design. To integrate fixes for high-severity issues that should be addressed on an accelerated schedule, Cisco may also release a rebuild of a Cisco NX-OS Software release.


This type of release, sometimes referred to as a support patch , reduces the possible impact on customers who have already certified and deployed a release. The name of each release contains a major release number, a minor release number, a maintenance release number, and, if appropriate, a rebuild identifier. There are two sets of release-naming conventions for the software:.


Figure The following table Table 6 shows valid values for the platform designator in this naming convention.


All applicable features, functions, and fixes in the platform-independent code are present in each platform-dependent release.


Cisco IOS Software uses software packaging models and architectures that are designed to meet the requirements of specific service and market categories and to simplify the selection process for software images.


The Cisco IOS Software packaging model is designed to simplify the image selection process and the deployment of critical functionality. It does so by consolidating packages to reduce the total number of packages and by using consistent package names across all hardware products. The packages provide similar functionality and logical feature parity across platforms, while also meeting the unique requirements of each platform.


This feature is an orchestrated collection of processes and components that enables administrators to activate specific Cisco IOS Software feature sets by obtaining and validating Cisco software licenses for those feature sets. With the Cisco Software Activation feature, administrators can enable licensed features and register licenses by using the Cisco Product License Registration portal, issuing EXEC commands directly on a device, or using Cisco License Manager to register, obtain, and install licenses in a bulk fashion for network-wide deployments.


Consequently, these switches and routers ship with a single, universal Cisco IOS Software image that contains all available features. Administrators can then obtain specific licenses to enable the corresponding feature sets. There are two types of universal software images:. Within each universal software image, features are grouped into feature sets. Administrators activate specific feature sets by using technology package licenses via Cisco Software Activation licensing keys.


The feature sets are:. Cisco IOS Software for other models of Cisco switches and routers can use any of seven different software packages, depending on the model, to meet the requirements of different market categories. The software packages are:. The name of a software image indicates which software package the image contains and whether the image includes strong cryptography features.


If an image name contains the k9 designation, the image includes strong cryptography features. For example, if an image name contains adventerprisek9 , the image contains an Advanced Enterprise Services package that includes strong cryptographic features. A consolidated package is a single software image that contains a collection of software subpackages.


A subpackage is an individual software file that provides a specific set of functionality or controls a different element or elements of a router or switch. The diagram also shows how each subpackage provides a different set of functionality that complements or supports the functionality provided by one or more other subpackages in the same consolidated package. The consolidated package architecture enables administrators to install and upgrade the software by using a holistic or modular approach.


Administrators can install and run all the subpackages in a consolidated package or only specific subpackages in a consolidated package.


In addition, administrators can upgrade the software by performing a single, complete upgrade process that upgrades all the subpackages in a consolidated package or they can upgrade each software subpackage independently. For more information about the advantages and disadvantages of running individual subpackages or complete consolidated packages, and the process of extracting individual subpackages from a consolidated package, see the Cisco ASR Series Aggregation Services Routers Software Configuration Guide.


For information about which consolidated packages are available for a specific release of Cisco IOS XE Software, see the release notes for the release. Each package contains components that support a specific set of features or functions, such as routing, security, or modular services card MSC support. Administrators can then add and activate additional optional packages and software maintenance updates SMUs on the device as necessary to provide additional specific features and to address issues.


For information about which features and components are included in a specific Cisco IOS XR Software package, see the release notes for the package.


The filename of a software image indicates the target platform, the applicable feature set, and other information about the software image contained in the file.


Administrators can determine which software image and release is running on a device by issuing the show version command in the CLI and reviewing the output of the command. The name of each Cisco IOS Software image indicates the applicable hardware, feature set, software release, and other information about the image.


To determine which Cisco IOS Software image and release is running on a device, administrators can log in to the device, issue the show version command in the CLI, and then review the output of the command. To determine which Cisco IOS XE Software image and release is running on a device, administrators can log in to the device, issue the show version command in the CLI, and then review the output of the command. The output indicates the name and type of the software release that is running on the device Administrators can additionally determine which subpackages and subpackage versions are running on the active route processor RP by issuing the show version rp active running command in the CLI and referring to the value in the Package field of the command output.


The following example shows the output of the command for the Cisco ASR X Router that is used in the preceding example:. To determine which release of Cisco IOS XR Software is running on a device, administrators can log in to the device, issue the show version command in the CLI, and then review the output of the command.


Continuing with the preceding example, the output of the command is as follows for the chassis. Note that the output also indicates where the node stores the active package Boot Device and the location of the minimum boot image MBI that is used to boot the node Boot Image.


The name of each Cisco NX-OS Software image indicates the applicable hardware, feature set, software release, and other information about the image.


To determine which release of Cisco NX-OS Software is running on a device, administrators can log in to the device, issue the show version command in the CLI, and then review the output of the command.


Figure 18 shows the typical phases and milestones in the lifecycle of a software release. After the last date of support, the release has reached the end-of-life milestone and is obsolete, which means the release is not sold, manufactured, improved, repaired, maintained, or supported. For detailed information about end-of-sale and end-of-life milestones, see the End-of-Life Policy. Although software retirement is not a formal milestone in the software-release lifecycle, software releases that are published to the Software Center on Cisco.


For applicable platforms that have not reached the end-of-software-maintenance milestone, software releases are not retired and removed from the Software Center unless a viable migration path exists.


A viable migration path does not cross critical memory boundaries for supported hardware and, if applicable, has a similar internal or external certification.


In addition, retirement and removal of a software release from the Software Center is subject to deferral at any time in the event that a widespread, catastrophic software defect is discovered. Regardless of whether a release is available from or is eligible for retirement and removal from the Software Center, Cisco recommends that administrators maintain copies of all software releases that are running on a network.


Cisco also recommends that administrators implement only current releases of software; Cisco does not recommend new deployments of retired software releases. However, software releases are retired primarily based on age.


If Cisco retires a software release that is running on a network, it does not mean that the software should automatically be replaced on that network. In other words, if the software meets customer needs, the customer can continue to use it.


In addition, the Cisco TAC will continue to provide service and support for a retired software release until the release reaches the published, last date of support. The code selection process involves a number of different variables.


Cisco recommends minimizing the number of software releases that are deployed in any network environment and establishing a software strategy that indicates which releases and images will be used by different devices that are deployed throughout the environment. To maximize operational efficiency, it is ideal to use the same software release on devices that have similar hardware and feature deployments.
