But what does that mean? Where and how is 5G being deployed? What is Wi-Fi 6? Created by xthuijs on AM. The question loadbalancing is one of the more complex items in hardware forwarding. Ask a Question. Find more resources. In the Download Software Center, SMUs of this type include the installation impact of either hitless or traffic loss in the file information section.

Some SMUs require the router to reboot in order to safely activate the patch. A SMU may impact key base components in the operating system and require a reload of the device for these reasons:. 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.

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.

A SMU delivers a software change to the user in the least possible time. ISSU minimizes the operational impact that a user experiences. 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 a SMU.

The ISSU process can be performed in 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. 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. If a 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.

They are built in order to verify a specific fix and only that fix. Engineering SMUs are not built from the production lineup and will negate or not include previous fixes in the same component. Note : Engineering SMUs are not subjected to the full test suite applied to a production SMU and therefore are not supported outside of a lab environment.

Support for such SMUs comes from the associated development teams. An engineering SMU is provided in order to test the validity of a fix in advance of the commit of the actual fix or, potentially, in advance of the delivery of a formal production SMU.

Engineering SMUs are removed after testing is complete. Bridge SMUs are also referred to as mandatory upgrade or downgrade SMUs because they must be installed before an upgrade or downgrade. This simplifies the software delivery model since a single SMU can fix many individual issues. The bug fixes that are included within an umbrella SMU may or may not be limited to a single component, although cross-functional umbrella SMUs that cross package boundaries are rare.

Umbrella SMUs are provided for platform dependent fixes that are considered mission critical. Umbrella SMUs are a collection of fixes that should be applied in order to maintain stability on any base software release. The SPs are designed so that they include all of the bugfixes in a single package in order to ease software maintenance.

Note : Only one SP should be active on the router at a time. 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:.

Note : The SP activation requires a system reload. Examples include:. Email iosxr-file-exchange cisco. Cisco recommends you review the associated Readme file before you install a SMU. Here is an example of the Readme file for asr9k-px 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, customer impact, and the engineering feasibility of a point fix.

SMUs that are not proactively created by the Business Unit must be formally requested by a network administrator. This information is required when a SMU is requested:.

If a SMU is rejected, the reasons are documented, and the requester is informed about the decision. 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.

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 overlapping component, there is no need to run them both at the same time. SMU Y, while committed to the lineup, inherently takes the changes from X already.

If you are already running 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. So, loading Z would negate the changes applied by Y. Partial supercede does not always mean there has to be a prerequisite dependency and depends on the code fix.

SMU Y is a partial supercede over X because there are some overlapping components. You must install both SMUs in order to get both fixes. That means that, in order to run Y, you need X as well. Certain fixes might have a dependency on a previously posted SMU for a complete solution.

So, by definition, if a new SMU contains fixes for separate components within the same package, and if there is an existing SMU 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 SMU are required for a complete fix. SMUs that are fully superceded are removed from Cisco.

A composite SMU can contain multiple components. 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. Use the install add operation in order to add a 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. The SMU can be copied to a hardisk: or other local media first, then be added from that local media. The FTP username and password are configured with the ftp client username and ftp client password configuration commands, or they can be specified inline in the install add command.

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. You can create and add a custom tarball file of individual SMUs. 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.

Use the show install inactive admin command in order to verify the ability to activate a SMU. After a SMU is successfully added to the system, a message is displayed that the operation completed successfully and the SMU can be activated on the router. The message displays the name of the package SMU that is now available to be activated. It also lists the install operation ID of the add operation that can be used in order to activate all the packages that were added in an install add operation.

When you work with recommended SMU tarballs, the install ID of the previous add operation must be used in order to activate all the SMUs in the tarball.

Use the admin install activate command with the help option a question mark in order to list all the packages including SMUs that can be activated. Only the SMU disk0:asr9k-p To make a SMU activation persistent across reloads, you must commit the change with the install commit admin command. Skip to content Skip to search Skip to footer.

Their installation impact may be either hitless or traffic loss. Umbrella SMUs may be provided for platform dependent fixes or platform independent fixes. SPs are released approximately every eight weeks. The install operation will continue asynchronously. Use the Info: command ' admin install commit' to make changes persistent.
