SMU Management
Cisco Software Manager
The Cisco Software Manager (CSM) provides Cisco IOS XR SMU recommendations to users and reduces the effort that it takes for you to manually search, identify, and analyze SMUs that are needed for a device. The CSM can connect to multiple devices and provide SMU management for multiple Cisco IOS XR platforms and releases.
The CSM 3. x is a server application that can be installed on various Linux distributions. Through CSM Server users can orchestrate the installation of any Cisco IOS XR software package, that includes SMUs.
The CSM 2. x is a standalone Java application that can be installed on Microsoft Windows, Macintosh, and UNIX systems. The CSM supports all Cisco platforms that run Cisco IOS XR. Support for CSM 2. x was discontinued after the introduction of CSM 3. x.
Cisco IOS XR SMU Overview
An SMU is a software patch that is installed on the Cisco IOS XR device. The concept of an SMU applies to all Cisco IOS XR hardware platforms.
A Cisco IOS XR SMU is an emergency point fix, which is positioned for expedited delivery and which addresses a network that is down or a problem that affects revenue.
When the system runs into a software deficiency (bug), Cisco can provide a fix for the particular problem in the base current Cisco IOS XR release. This is a substantial difference from the classic Cisco IOS software, which has no capability to apply a single fix in the base current release.
An SMU is built on a per release and per component basis and is specific to the platform. This means that an SMU for a CRS router cannot be installed on an ASR 9000 router. An SMU built for Cisco IOS XR software Release 4.2.1 cannot be applied to a system with Cisco IOS XR software Release 4.2.3. An SMU built for a P image cannot be used on a system built for a PX image.
SMUs are provided for urgent, “showstopper” issues only. The fix provided by the SMU is then integrated into the subsequent Cisco IOS XR software maintenance release. Cisco strongly encourages you to upgrade to the subsequent maintenance release.
SMUs are Package Installation Envelope (PIE) files that are similar in functionality and installation to the feature PIEs for manageability (MGBL), Multiprotocol Label Switching (MPLS), and Multicast.
Types of SMUs
Production SMU
A production SMU is an SMU that is formally requested, developed, tested, and released.
Production SMUs are intended for use in a live network environment and are formally supported by the Cisco TAC and the relevant development teams. Production SMUs are provided for critical live operation issues on a supported maintenance release. Production SMUs are characterized by package types, impact and criticality, and restart or installation impact type.
Production Software Maintenance Updates (SMU) are provided on user requests on supported maintenance releases for service that impacts issues observed in production or during maintenance release validation, for which there is no feasible workaround. Software bugs identified through software recommendations or Bug Search Tools are not a basis for Production SMU requests. Cisco continuously reviews software bugs that affect supported maintenance releases and provides Proactive Production SMU requests when Cisco deems them necessary. Cisco reserves the right to maintain strict control over Production SMU delivery, to maintain the stability of the code base and prevent collateral damage.
Production SMU Types
Mandatory production SMUs are critical fixes that are mandatory in order to maintain the proper functionality of the device.
Recommended production SMUs are critical fixes that are strongly recommended in order to maintain the proper function of the device. They typically consist of platform and infrastructure SMUs and composite SMUs. You can access recommended production SMUs at the Download Software Center if you are a registered Cisco Connection Online (CCO) user.
Optional production SMUs provide fixes that are desirable but are not required in order to maintain stability. They are typically deployed based on bugs within specific features. You can download optional production SMUs from the File Exchange (releases earlier than 4.2.3) or from the Download Software Center (Release 4.2.3 and later).
Production SMU Restart Types
Each SMU has a restart type of dependent or reboot:
- SMUs that are parallel process restart SMUs are considered a dependent restart type. Their installation impact can be either hitless or traffic loss.
- SMUs with a reboot restart type can have an install method of parallel reload or of in-service software upgrade (ISSU) if ISSU is supported by the operating system and the platform.
Each SMU has a README file that documents the restart type and installation impact of the SMU.
Dependent SMU (Parallel Process Restart)
Dependent SMUs require process restarts during activation. One or more processes are restarted on nodes in parallel. SMUs of this type are marked as restart type dependent in the Readme file that accompanies the SMU.
The SMU also has an installation impact of hitless or traffic loss. In the Download Software Center, SMUs of this type include the installation impact of either hitless or traffic loss in the file information section.
Reboot SMU with Parallel Reload Install Method
Some SMUs require the router to reboot in order to safely activate the patch. Such SMUs are marked as restart type reboot in the Readme file for the SMU. The Readme file is posted on the File Exchange or as part of the tarball on the recommended SMUs portal on CCO. In the Download Software Center, SMUs of this type include the designation of Reload SMU in the file information section.
An SMU can impact key base components in the operating system and require a reload of the device for these reasons:
- Changes to the Minimum Boot Image (MBI)
- Changes to the kernel
- Changes to the Network Processor (NP) or Packet Switching Engine (PSE) microcode
If an SMU requires more than ten different process restarts, the SMU is created as a reboot SMU for safety reasons and for system stability.
Reboot SMU with ISSU Install Method
ISSU provides the ability to upgrade the router software with no outage on the control plane and with minimal outage (generally within several seconds) on the forwarding plane. ISSU is a user-initiated and user-controlled process that uses Cisco Nonstop Forwarding (NSF) with stateful switchover (SSO). ISSU upgrades an SSO-NSF-capable image from a lower to a higher version or installs ISSU SMUs with minimal downtime, degradation of service, or loss of packets. Not all Cisco IOS XR platforms and Cisco IOS XR versions support ISSU. Refer to Release Notes documentation for your product to verify the support for ISSU.
To achieve ISSU, the Cisco IOS XR software uses the ISSU Minimal Disruptive Restart (iMDR) software. iMDR is the warm reload technology that allows line cards to be upgraded as if they were redundant in hardware. iMDR effectively separates the CPU and CPU memory of the line cards from the forwarding ASICS, memory, and Ternary Content Addressable Memory (TCAM) of the line cards. Think of the CPU and CPU memory as the software portion of the line cards, and think of the forwarding ASICS, memory, and TCAM as the hardware portion of the line cards. iMDR allows the software portion of the cards to be upgraded to a new version while the hardware portion continues to perform its duties under the old version. After the software portion upgrades itself and stages the information needed in order to upgrade the hardware portion, it performs a flush to replace the old version with the new version. This flush generally takes no more than several seconds, which is the only time there is a disruption of service. The exact time required for the flush depends on the hardware configuration of your router.
An SMU delivers a software change to the user in the least possible time. Before ISSU support, SMU installations resulted in either restart of one or more processes, or reload of one or more nodes. ISSU minimizes the operational impact that a user experiences.
Not all Reload SMUs qualify to be ISSU SMUs. Certain changes to the kernel, ROMMON, memory carving, and other infrastructure areas cannot be achieved with a warm reload; in such instances, the router must undergo a standard reload in order to load such an SMU.
To perform an ISSU SMU upgrade, use the issu keyword with the install activate command. If an ISSU SMU is activated without the issu keyword, the SMU is installed with the parallel reload method.
To remove the Software Maintenance Updates (SMU) package from the committed software using ISSU, use the install deactivate issu <smu2> <smu1> command in XR EXEC mode. If an ISSU session is in progress, this command is blocked until the ISSU session is complete. If the ISSU SMU is deactivated without the issu keyword, the SMU is deactivated with the parallel reload method. To commit the change, use the command install commit.
The ISSU process can be performed in a prompted mode in order to ensure and verify that there is no service degradation throughout the process. Or, the ISSU process can be unprompted, where the phases are executed automatically with no user intervention.
View the output of the show install package pie detail admin command in order to identify the SMU type. ISSU SMUs are identified by ISSU (quick) warm-reload in the Restart information field.
In the software download center, SMUs of this type include the designation of ISSU/Reload in the file information section.
Production SMU Installation Impact
Hitless
Most SMUs can be applied without impact to normal router operations (routing and forwarding) and are classified as hitless SMUs. Hitless SMUs are parallel process restart SMUs that can be activated without an effect on the operation of the device.
Traffic Loss
If an SMU addresses a problem within a routing protocol, the process that runs the protocol restarts when you apply the SMU.
If you use graceful restart extensions with default timers, traffic continues to be forwarded without interruption, and protocol sessions are re-established.
If you do not use graceful restart extensions, routing protocol sessions are terminated and restarted. Traffic is diverted away from the affected router when neighbors detect the session has terminated. If the loss of traffic is expected as a consequence of the SMU installation, the SMU is classified as a traffic loss type SMU.
Engineering SMU
An engineering SMU is a “private” SMU provided to a network administrator in order to address key and critical issues found during software qualification processes. They are built in order to verify a specific fix and only that fix. Engineering SMUs are not built from the product lineup and negate or do not include previous fixes in the same component.
An engineering SMU is provided in order to test the validity of a fix in advance of the commitment of the actual fix or, potentially, in advance of the delivery of a formal production SMU. Engineering SMUs are removed after they are tested.
PSIRT SMU
In response to a critical, security-related issue, an SMU is released under the guidance of the Cisco Product Security Incident Response Team (PSIRT). PSIRT SMUs are provided on all affected, supported maintenance releases. PSIRT SMUs have a priority of urgency and are announced through a Security Advisory.
Bridge SMU
A bridge SMU is an SMU that is a prerequisite to an upgrade or downgrade to another Cisco IOS XR software release. Bridge SMUs are also referred to as mandatory upgrade or downgrade SMUs because they must be installed before an upgrade or downgrade.
Refer to Cisco IOS XR General Information for procedures for each upgrade or downgrade and for details of any mandatory bridge SMUs.
Bridge SMUs are also included in the Cisco IOS XR software tar bundles located in Download Software Center for a particular release. The Cisco IOS XR software tar bundle includes all available PIEs for the release and any bridge SMUs for other Cisco IOS XR releases needed in order to perform the upgrade.
Umbrella SMU
An umbrella SMU is a collection of individual bug fixes included in one SMU package.
A new bug ID in the Distributed Defect Tracking System (DDTS) is assigned and is an aggregation of a set of bugs under that new umbrella bug ID. The release note of the umbrella bug ID includes a list of all bugs that the SMU fixes. This simplifies the software delivery model since a single SMU can fix many individual issues.
The terms combo SMU, umbrella SMU, and SMU pack refer to the same type of SMU.
The bug fixes that are included within an umbrella SMU can or can not be limited to a single component, although cross-functional umbrella SMUs that cross package boundaries are rare.
Umbrella SMUs can be provided for platform-dependent fixes or platform-independent fixes.
- A platform-dependent fix is an issue that pertains to one specific platform such as an ASR9000, CRS, or XR12K. For example, Cisco bug ID CSCud37351
423 SMU Pack2 applies to ASR9K NP, PRM, and DRV fixes. - A platform-independent fix, such as Cisco bug ID CSCud08809 Cisco bug ID CSCud08809 " />Traffic Loss, BGP Umbrella DDTS #1, spreads across all XR platforms.
Umbrella SMUs are provided for platform-dependent fixes that are considered mission-critical. Umbrella SMUs are a collection of fixes that can be applied in order to maintain stability on any base software release.
Service Packs
A Service Pack (SP) is a special type of umbrella SMU that contains a roll-up of all the previously released SMUs. The SPs are designed so that they include all of the bug fixes in a single package in order to ease software maintenance.
Here are some important notes about SPs:
- SPs are only supported on Cisco IOS XR releases with no other SMUs present. This means that a mix of SMUs and SPs is not supported.
- SPs are released approximately every eight weeks.
- SPs are not available for all Cisco IOS XR releases.
In this example, there are three SPs that have been released for Cisco IOS XR Version 4.3.2:
- Cisco IOS XR 4.3.2 Service Pack 1 for ASR9K-PX platform (asr9k-px-4.3.2.sp-1.0.0.pie)
- Cisco IOS XR 4.3.2 Service Pack 2 for ASR9K-PX platform (asr9k-px-4.3.2.sp2.pie)
- Cisco IOS XR 4.3.2 Service Pack 3 for ASR9K-PX platform (asr9k-px-4.3.2.sp3.pie)
In order to install the latest SP, you must add, install, and commit the latest SP. In this example, SP2 is added to a router that already runs SP1. The presence of SP1 is not required before SP2 works.
In order to verify if an SP currently runs on your system, enter the show install active summary command:
RP/0/RSP0/CPU0:router(admin)#show install active summary

SMU Naming Convention
A SMU consists of the SMU binary file and its associated Readme text file, which contains any associated caveats. Examples include:
- hfr-px-4.2.3. Cisco bug ID CSCue43799 .pie
- hfr-px-4.2.3. Cisco bug ID CSCue43799 .txt
- hfr-p-4.2.3. Cisco bug ID CSCue43799 .pie
- hfr-p-4.2.3. Cisco bug ID CSCue43799 .txt
- asr9k-px-4.3.0. Cisco bug ID CSCue35562 .pie
- asr9k-px-4.3.0. Cisco bug ID CSCue35562 .txt

- asr9k-p-4.2.0. Cisco bug ID CSCus50217 .txt
- asr9k-px-4.2.0. Cisco bug ID CSCus50217 .pie
- asr9k-px-4.2.0. Cisco bug ID CSCus50217 .txt
The naming convention uses the format platform-type-release-DDTS ID-file format.
- Platform:
- hfr (CRS)
- c12k (12000)
- asr9k (ASR 9000)
- ncs6k (NCS 6000)
- ncs5k (NCS 5000)
- ncs5500 (NCS 5500)
- xrv9k (XRv9000)
- Image type:
- p
- px
- Release: 4.3.0, for example
- DDTS ID: Cisco bug ID CSCxx12345 , for example
- File format:
- .pie
- .txt
- .tar
Note that:
- There are no PX PIE/SMU image types in Cisco IOS XR software releases earlier than 4.0.
- SMUs earlier than Release 4.0 do not include the image type; instead, the SMUs include the package that the SMU affects.
- With Cisco IOS XR software Release 4.3.0 and later, the PX PIE image type is the only option on ASR9000 and CRS platforms. P images are no longer supported. The P images are now converged with PX. Through the normal upgrade process, the migration happens to PX.
- Composite SMUs earlier than Cisco IOS XR Release 4.0.0 are named comp-*. Example: comp-hfr-3.9.3. Cisco bug ID CSCtq84280
Download SMUs from Cisco.com
SMUs are located in two key repositories: the Download Software center and the File Exchange.
Download Software Center
SMUs can be downloaded from the Cisco Download Software Center.
- In the Download Software Center, navigate to the router platform type. In this example, navigate to Downloads Home > Products > Routers > Service Provider Edge Routers > Cisco ASR 9000 Series Aggregation Services Routers > Cisco ASR 9006 Router.
- Select IOS XR Software Maintenance Upgrades (SMU) or IOS XR Software Maintenance Upgrades (SMU) Bundles as shown in the image.
- If you selected IOS XR Software Maintenance Upgrades (SMU), select the release that corresponds to the Cisco IOS XR version in the SMU section, and download any mandatory, recommended, or optional SMUs.
- The SMU section includes individual mandatory, recommended, and optional SMUs that are packaged as tar files. The tar file of an individual SMU includes the SMU and the Readme file.
- The tar file can either be installed as it uses a special tar option, or you can uncompress the tar file and install the individual SMU.
- If you selected IOS XR Software Maintenance Upgrades (SMU) Bundles, the SMU Bundles Section provides tarball files that include all the recommended and mandatory SMUs for a specific release and platform. Each tarball includes all the recommended SMUs and their Readme files. SMU tarballs have a release date and are updated periodically with the addition of other recommended and mandatory SMUs.
- The recommended SMU tarball can be installed as it is uses a special tar option, or you can uncompress the tar file and install each individual SMU.
File Exchange
SMUs can be downloaded from the Cisco File Exchange.
Optional SMUs were not posted in the Download Software Center earlier than Cisco IOS XR software Release 4.2.3. So, those optional SMUs needed to be downloaded from the File Exchange or posted with special access by a TAC engineer.
SMUs on the File Exchange require special permission, and you must request access in order to download a specific SMU. Email iosxr-file-exchange@cisco.com in order to request access; include your name, company, and issue in the subject line, and include problem details in the message body.
Optional SMUs for the latest software releases are now available in the Download Software Center. Access to the File Exchange is not needed for most SMUs.
SMU Readme File
Each SMU tar file contains a SMU (.pie) and the Readme file. Cisco recommends you review the associated Readme file before you install a SMU.
The Readme file provides this information:
- Console and error messages during SMU activation or deactivation
- SMU installation impact
- Side effects and possible workarounds
- SMU caveats
- Package(s) that the SMU impacts
- Prerequisites
- Supercedes
- Restart type
- On-the-box name of the SMU
Here is an example of the Readme file for asr9k-px-4.2.3. Cisco bug ID CSCud29892 .pie.

SMU Caveats:
None
SMU Criteria and Policy
SMU requests are evaluated on a case-by-case basis. Directors or approved designates have the approval authority. The decision is based on the business justification, user impact, and the engineering feasibility of a point fix.
Official Production SMU Characteristics
Characteristics of an official production SMU are:
- It is not an alternative to a maintenance release.
- It is specific to package versions and is meant for all users.
- The bug fix is not user-specific in nature.
- It is fully supported by TAC.
- New fixes are integrated into subsequent maintenance releases.
- There have been specialized testing for collateral damage, but the scope is limited compared to maintenance releases.
SMU Evaluation Criteria
A new production SMU request can be accepted based on these criteria:
- It addresses a critical problem that causes user outages.
- It addresses a critical problem that impacts live network deployment.
- It is a mandatory SMU, recommended by PSIRT or Cisco.
- There is no viable operational workaround for the user.
- The schedule for maintenance release is not feasible for the particular user.
- It addresses an issue that impacts revenue, such as billing or monitoring (counters, network management).
SMU Requests and Approval
SMUs that are not proactively created by the Business Unit must be formally requested by a network administrator.
A TAC Service Request must be open with a bug ID in resolved state.
TAC, Advanced Services, and Business Unit Deployment Engineers can request SMUs. This information is required when an SMU is requested:
- Bug ID (DDTS)
- Platform (ASR9K-P, ASR9K-PX, CRS-1, CRS-P, CRS-PX, XR12000)
- Release
- Requesting company
- Service request number
- Input details or justification
- Upgrade plans
- Other comments
If an SMU is accepted, the SMU team schedules the build and provides an estimated date for delivery. If an SMU is rejected, the reasons are documented, and the requester is informed about the decision.
SMU Rejection Scenarios
An SMU request for either an engineering or production SMU can not be accepted in some situations:
- The issue is cosmetic.
- A workaround exists that does not require a network redesign.
- The proposed solution is beyond the scope of a straightforward bug and is considered to be a feature.
- The solution is a command-line interface (CLI) change.
- The release or the package version for which the SMU is requested is no longer supported.
- The fix is integrated into a subsequent maintenance version within the same major/minor Cisco IOS XR release. An SMU can be provided as a proactive fix until the next maintenance release or a subsequent release can be qualified for deployment. This is done at the discretion of the Business Unit executive management.
SMU Delivery Timelines
Once Cisco TAC has officially confirmed that an SMU is to be provided, an SMU must go through these stages before it is released or posted:
- SMU requested (by, for example, a TAC engineer)
- SMU accepted after a management review; timelines set for delivery
- SMU assigned to a Development Engineer
- SMU Unit Testing conducted by Development Engineer
- SMU Dev Testing is conducted by the component testing group at the component level - for example, at the Border Gateway Protocol (BGP) or Open Shortest Path First (OSPF) protocol level
- SMU System Integration Testing conducted by the platform team, such as the ASR9K, CRS, or XR12000 team
- SMU released to Cisco.com or File Exchange
The timelines for SMU delivery typically range between six and eight weeks but can vary.
The majority of delays occur during system integration testing because the SMU is subject to the particular issue it fixes. The SMU is also tested in a multi-dimensional test scenario in order to ensure there are no collateral failures in other components.
SMU Supercedes and Prerequisites
Supercedes
An important concept to understand is that SMUs are committed to a software lineup particular to that release. If there are two SMUs in the same component that overlaps, there is no need to run them both at the same time.
This example illustrates the concept of a supercede.
SMU X fixes a Link State Advertisement (LSA) flooding issue in OSPF and contains the new OSPF process and libraries. SMU Y fixes a crash in the OSPF process. If Y was delivered after X, Y contains the fixes for both issue X and issue Y. SMU Y, while committed to the lineup, inherently takes the changes from X already. If you run Y, you do not need the SMU for X anymore. If you run the superceded SMU, you can remove it in order to save space; however, if both the SMUs are installed, that does not cause a problem.
Subsequently, if there is an SMU Z also in OSPF, then Z can not contain the changes from Y if the changes were not committed to the SMU lineup. So, when you load Z, it negates the changes applied by Y.
Partial Supercedes
A partial supercede SMU is one that includes some components of another SMU that overlap, but not all.
A partial supercede implies that some components from a previously posted SMU are not superceded by a new SMU. Partial superceded does not always mean there has to be a prerequisite dependency and depends on the code fix.
This example illustrates the concept of a partial supercede.
SMU X contains a change in OSPF and some library changes. SMU Y is another OSPF change as in the Supercedes example but has no library changes. SMU Y is a partial supercede over X because there are some components that overlap.
You must install both SMUs in order to get both fixes. The SMU is built to include this dependency; while you install Y, the SMU indicates that X is needed as well.
Prerequisites
A prerequisite SMU is an SMU that must be installed in order to install another SMU.
In the example mentioned previously, Y has a prerequisite of SMU X. That means that, in order to run Y, you need X as well.
Certain fixes can have a dependency on a previously posted SMU for a complete solution. This is true for scenarios where a composite SMU is built and is followed by another SMU for a fix that touches one of the components included in the composite SMU.
So, by definition, if a new SMU contains fixes for separate components within the same package, and if there is an SMU that exists that contains at least one, but not all, of these components, the first SMU is not completely superceded by the new SMU. Both the old and new SMUs are required for a complete fix. Prerequisite SMUs must be activated either concurrently or before the new SMU is loaded.
Keep Track of SMU Prerequisites and Supercedes
SMUs that are fully superceded are removed from Cisco.com and the File Exchange in order to avoid confusion.
SMU Readme files document prerequisites and supercede.
The Cisco Software Manager helps manage SMUs because it identifies superceded and prerequisite SMUs and provides SMU recommendations and optimized SMU lists. Refer to the Cisco Software Manager User Guide for details.
In the latest Cisco IOS XR software releases, a message is displayed during the install operation when an SMU is activated that supercedes another. A composite SMU can contain multiple components. You can deactivate or remove some components of an SMU that have been superceded by another SMU without deactivation of the other SMUs.
This output helps identify what SMU packages have been superceded by other active packages and can be deactivated. The line items listed can be deactivated, but not the entire composite SMU. There is no problem if you continue to operate with SMU packages active that have been superceded by other active SMUs.
Info: After this install operation, some SMU package(s) will be superceded.
User can deactivate and remove superceded SMU(s).

In Cisco IOS XR software Release 4.3.0 and later, use the show install superceded admin command in order to help identify SMUs that have been fully superceded by other active SMUs and that can later be deactivated and removed.
RP/0/RP0/CPU0:ASR9922(admin)#show install superceded
Thu May 23 01:03:25.567 UTC
There are no fully superceded SMUs.
SMU Installation
SMU activation requires three operational steps:
- Add the SMU to the filesystem with the admin install add command.
- Activate the SMU on the system with the admin install activate command.
- Once confirmed that the system works as expected with the new SMU, make the installation persistent across reloads with the admin install commit command.
Install Add Operation
Use the install add operation in order to add an SMU to the file system. The install add operation adds all the SMU files to the filesystem but does not cause the SMU components to run or cause reloads or processes to restart.
There are several ways to perform an install add operation:
- Perform install add and install activate operations from admin mode or prefix the command with the admin keyword.
- Use the tar keyword in order to install and add individual SMUs that are in the .tar format or recommended SMU tarballs.
- Copy the SMU to a hard disk: or other local media first, and then add from the local media.
- Add the SMU to the filesystem directly from a TFTP or FTP file server that is reachable from the router. Note that:
- The SMU file must be available on the FTP or TFTP server and have proper read permissions for the FTP or TFTP operation.
- If the files on the FTP or TFTP server are not in the tftpboot directory, add the fully qualified path to the file on the FTP or TFTP server. In the next example, the files were in the tftpboot directory on the server tftp://10.0.0.1/asr9k-p-4.2.1. Cisco bug ID CSCue28217 .tar . Had they been in /tftpboot/smu then the command tftp://10.0.0.1/smu/asr9k-p-4.2.1. Cisco bug ID CSCue28217 .tar is used.

Use the source keyword option in order to specify the source location of the SMU. Because you can add multiple SMUs in one operation if you string together a list of SMUs with spaces between, use of the source keyword eliminates the need to specify the location of each SMU when you add a long list.

Example Install Add Operation - Custom Tarball from Recommended SMU Bundle
You can create and add a custom tarball file of individual SMUs. Copy all the SMU PIE files to add into a directory on the server, then use the tar -cvf command in order to create a custom SMU tarball of the SMUs to be added and activated.
In this example, a wildcard is used in order to add all the SMUs in the directory to the tarball. Alternatively, each SMU could have been specified individually in the command line.

Error Messages
Bootflash is Beyond 80% Utilization
This message can appear after SMU installation.
RP/0/RSP0/CPU0:Jul 9 17:40:37.959 : wdsysmon[447]: %HA-HA_WD-4-DISK_WARN : A monitored device /bootflash: is above 80% utilization. Current utilization = 89. Please remove unwanted user files and configuration rollback points.
This message can be safely ignored.
As per the design, it is expected that Cisco IOS XR keeps up to two MBIs on the boot flash that comes after the SMU install(s). At subsequent SMU install(s), if the bootflash space required by the new package(s) is not available, Cisco IOS XR cleans up automatically old MBIs to make space for the new MBI package.
