The install all command triggers the installation upgrade. The compatibility checks display the impact of the upgrade. The installation proceeds or not based on the upgrade impact. The stateful restart of the system software and application occurs. The following list summarizes the upgrade process on a primary switch in a vPC topology.

Steps that differ from a switch upgrade in a non-vPC topology are in bold. Note In vPC topologies, the two peer switches must be upgraded individually. An upgrade on one peer switch does not automatically update the vPC peer switch. The install all command issued on the vPC primary switch triggers the installation upgrade. The configuration is locked on both vPC peer switches. When the installation is complete, the vPC primary switch and the FEXs that are connected to the primary switch are upgraded.

The vPC primary switch is running the upgraded version and the vPC secondary switch is running the original software version. The following list summarizes the upgrade process on a secondary switch in a vPC topology. The install all command issued on the vPC second switch triggers the installation upgrade.

The FEXs are upgraded sequentially. Note The dual-homed FEXs were upgraded by the primary switch. The configuration is unlocked on the primary and secondary switches. Doing a disruptive upgrade between incompatible images will result in loss of certain configurations such as unified ports, breakout, and FEX configurations.

For FEX configurations, prior to the downgrade, the configuration must be converted if not already used to use FEX pre-provisioning configuration. The following lists the situations where a nondisruptive ISSU might not be possible when upgrading a Cisco Nexus device:. Perform the following steps to restore the configuration if the configurations contain interface breakout or unified port configurations:.

Use the default interface command to restore the default configurations of the breakout interfaces. Save the running configuration to startup configuration using the copy running-config startup-config command. In case of VPC, downgrade the primary switch first and then the secondary switch. After the switch is up, power-off and power-on the module for the interface breakout to be effective. If the breakout is configured on Baseboard module, save the running configuration to startup configuration using the copy running-config startup-config command and then reload the switch again.

If breakout is not configured on the Baseboard, then an additional reload is required if running configuration contains hardware profile route resource service-template. Verify if all the interfaces are up and traffic is resumed. You can choose to do a disruptive upgrade if one of the ISSU conditions are not met.

One additional reason where you might choose to do a disruptive upgrade is when FEXs are upgraded in a rolling fashion one FEX at a time , which requires a longer maintenance window. With a disruptive upgrade, all the connected FEXs are upgraded simultaneously, so the maintenance window can be shorter. If you need a shorter maintenance window with traffic disruption , you can force a disruptive upgrade even if an ISSU can be leveraged. It is important to note the possibility of an outage if you do a disruptive upgrade.

You can also add the force keyword at the end of the install all command as follows:. An upgrade from these releases is disruptive. Step 1 Log in to Cisco. Note Unregistered Cisco. Navigate to the software downloads for Cisco Nexus devices. Links to the download images for the switch are listed. Step 2 Choose and download the kickstart and system software files to a local server.

Step 3 Verify that the required space is available in the bootflash: directory for the image file s to be copied. We recommend that you keep the kickstart and system image files for at least one previous software release to use if the new image files do not load successfully. Step 4 Optional If you need more space on the bootflash, delete unnecessary files to make space available. Step 7 Install the new images, specifying the new image names that you downloaded in the previous step.

Step 8 Verify that the switch is running the required software release. The reload is a cold reboot that brings down the control plan and the data plane. The reload causes disruptions to the connected servers and hosts. When one of the vPC switches is being reset during the upgrade process, all the server traffic can flow through its vPC peer.

The following figures show topologies in which the access layer includes a vPC configuration to hosts or downstream switches. To upgrade the access layer without a disruption to hosts, follow these tasks:. Note Flows that are forwarded to a switch during an upgrade on the switch, will failover to the second switch. Also, flows are redistributed when vPC peers are active.

The traffic disruption is limited to the time required for the server or host to detect the link-down and link-up events and to redistribute the flows. A disruptive upgrade causes a switch and connected FEXs to reload. The time required for a FEX to reload is less than the time required for a switch to reload. When hosts are connected to a dual-homed FEX, it is possible to keep the traffic disruption of the hosts to same time as required by FEX to reload approximately seconds , instead of the time required for an upgrade of the entire access layer.

The following figure shows a dual-homed FEX topology in which the access layer includes a vPC configuration to hosts or downstream switches. Note The following dual-homed FEX procedure is supported only for an upgrade and not for a downgrade. Upgrade the vPC primary switch with the new image using the install all kickstart image system image command. During the upgrade process, the switch is reloaded. When the switch is reloaded, only singled-homed FEXs connected to the switch are reloaded and dual-homed FEXs are not reloaded.

Servers connected to the dual-homed FEXs retain network connectivity through the vPC secondary switch. Step 2 Verify that the upgrade of the vPC primary switch is completed successfully. At the completion of the upgrade, the vPC primary switch restores vPC peering. The servers connected to the dual-homed FEXs will lose connectivity. Step 4 Wait for the FEXs to reload.

Step 5 Upgrade the vPC secondary switch with the new image using the install all kickstart image system image command. Step 6 Verify that the upgrade of the vPC secondary switch is completed successfully. At the completion of the upgrade, the vPC secondary switch restores vPC peering.

Dual-homed FEXs connect to both the peer switches and start forwarding traffic. Perform this step on both the switches in a vPC pair. Step 7 Enter the show install all impact command to validate the upgrade process and the components being upgraded. Step 8 Enter the install all kickstart image system image command on the vPC primary switch. During the software upgrade on the primary switch, you can view the FEX upgrade progress using the vPC secondary switch see the bold output :.

Step 9 Ensure that the upgrade on vPC primary switch is completed. Use the show version command to verify the upgrade on vPC primary switch. Note Only the vPC primary switch shows that the Fabric Extender is online because the vPC secondary switch does not have the new image. When all the Fabric Extenders are loaded, go to the next step. To upgrade the vPC secondary switch, follow Step 2 to Step 9.

Use the show fex command to view the FEX status. Table 8 lists the show commands that are used to monitor installation upgrades. Table 8 Monitoring the Upgrade Process. Displays the applications that failed during an installation and why the installation failed. Displays detailed logs of the last installation-related command. Displays detailed logs of the last five installation-related commands, from the oldest to the newest logs. Displays the system and configuration information that you can provide to the Cisco Technical Assistance Center when reporting a problem.

The following example shows the output from the show install all status command:. Note that the downgrades are disruptive. You can use the show incompatibility system command to ensure that there are no feature incompatibilities between the current release and the target release. After FEX pre-provisioning is done, perform the following steps to restore the configuration if the configurations contain interface breakout or unified port configurations:.

In case of vPC, downgrade the primary switch first and then the secondary switch. Note Before you downgrade to a specific release, check the release notes for the current release installed on the switch to ensure that your hardware is compatible with the specific release. Some common causes for ISSU failure are as follows:. The documentation set includes the following types of documents:. To provide technical feedback on this document or to report an error or ommission, please send your comments to nexus5k-docfeedback cisco.

We appreciate your feedback. The RSS feeds are a free service. Upgrade Guidelines When upgrading system software, follow these guidelines: Configuration changes You cannot enter global configuration mode during an upgrade. There are no active configuration sessions. Table 1 show install all impact Command and Output Terminology Term. You can receive descriptive information about the intended changes to your system before you continue with the installation.

For example, it identifies potential disruptive upgrades. Warning: please do not remove or power off the module at this time. Note: Power-seq upgrade needs a power-cycle to take into effect. This example shows how to determine the vPC operational role of the switch: switch-2 show vpc brief.

Peer status : peer adjacency formed ok. Configuration consistency status : success. Per-vlan consistency status : success. Type-2 consistency status : success. Number of vPCs configured : Peer Gateway : Disabled.

Dual-active excluded VLANs : -. Graceful Consistency Check : Enabled. PC peer keep-alive send has failed. Install pending. To perform a nondisruptive upgrade, in a vPC environment that has FEXs connected to a switch, perform the following steps: 1. Bridge Assurance is enabled when you configure an interface as a spanning-tree port type network. Not following these restrictions could render the network unstable if there are any unexpected topology changes If the STP conditions are not met, the installation check indicates that the upgrade would be disruptive.

Ethernet Interfaces on the Switch and the Fabric Extenders To avoid link-down to link-up transitions during the control plane outage time, the laser is turned off for administratively up ports that are operationally down. PreInstallation Checks You should do certain sanity checks to ensure that the system is ready for an ISSU and to understand the impact of ISSU: Enter the show incompatibility command to verify that the target image is feature-wise compatible with the current image.

Enter the show logging level command to ensure that the severity level for all processes is set to 5 or below. Enter the show vpc role command to verify the vPC switch role in a vPC topology. Review the installer impact analysis and choose to continue.

Table 6 Upgrade show Commands Command. Number Description State Model Serial. No Topology change must be active in any STP instance. Following are the statistics on this switch. Check Peer Switch. Performing module support checks. Notifying services about system upgrade. Module bootable Impact Install-type Reason. Images will be upgraded according to following table:. Please make sure to enable "disable-fka" on all logged in VFCs.

Active VNP ports with no disable-fka set. Installation At-a-Glance Table 7 shows an overview of the upgrade process. Copying the Running Configuration from an External Flash Memory Device You can copy configuration files from an external flash memory device. Copying the Startup Configuration from an External Flash Memory Device You can recover the startup configuration on your Cisco NX-OS device by downloading a new startup configuration file that was saved on an external flash memory device.

The current state is saved. The system unloads and runs the new image. The installer resumes with the new image. The installation completes. The following example displays the ISSU process: switch install all kickstart nuk9-kickstart. Install is in progress, please wait. Notifying services about the upgrade. Upgrade can no longer be aborted, any failure will result in a disruptive upgrade.

Kernel uptime is 0 day s , 0 hour s , 5 minute s , 31 second s. Last reset at usecs after Fri Jan 24 You cannot configure a device during an upgrade. Use the show configuration session summary command to verify that you have no active configuration sessions. Save, commit, or discard any active configuration sessions before upgrading or downgrading the Cisco NX-OS software image on your device.

On a device with dual supervisors, the active supervisor module cannot switch over to the standby supervisor module during the Cisco NX-OS software upgrade if you have an active configuration session. If you do not have a router to route traffic between subnets, ensure that the Nexus switch and the remote file server are on the same subnetwork. To verify connectivity to the remote server, transfer a test file using a file transfer protocol of your choice or use the ping command if the remote file server is configured to respond to ICMP Echo Request packets.

An example of using the ping command to verify connectivity to a remote file server If an incompatibility exists, disable any features that are incompatible with the downgrade image before downgrading the software. When you use install all with no-reload option, the saved configuration cannot be used before you reload the device. Saving configuration in this state can result in incorrect startup configuration once you reload the device with new version of NX-OS. The upgrade will be disruptive.

You can ignore these extra lines as they do not have an effect on the upgrade and configuration. If the port range is incorrect, follow the syslog message recommendation. Software image compaction is only supported on Cisco Nexus series platform switches. The compressed image of Cisco Nexus series is hardware dependent and can only be used on the same device that it got compressed or downloaded from CCO.

Do not use the Nexus series compressed image on Nexus series. The following limitation applies to software upgrades from 7. Failure to perform these steps results in error messages and the inability to modify the VLAN NetFlow configuration in the upgraded software. The workaround is to disable the spanning-tree etherchannel guard misconfig command on the IOS switch before starting the upgrade process.

Once both the Cisco Nexus Series switches are upgraded, you can re-enable the command. To recover from this, the following steps should be performed after all FEXs have come online and the HIFs are operationally up:. The error is in the output of the show consistency-checker dme running-config enhanced command, specifically, the event manager commands. An error occurs when you try to perform an ISSU if you changed the reserved VLAN without entering the copy running-config save-config and reload commands.

The install all command is the recommended method for software upgrades and downgrades because it performs configuration compatibility checks and BIOS upgrades automatically. In contrast, changing the boot variables and reloading the device bypasses these checks and the BIOS upgrade and therefore it is not recommended. For more information on the upgrade patch, see Patch Upgrade Instructions.

In the process, the contents of the guest shell 1. Any application running in the Guest Shell is affected. If you upgrade without shutting down the service, you can enter the feature sla sender command after the upgrade. Avoid any power interruption, which could corrupt the software image, during the installation procedure. On devices with dual supervisor modules, both supervisor modules must have connections on the console ports to maintain connectivity when switchovers occur during a software upgrade.

See the Hardware Installation Guide for your specific chassis. Perform the installation on the active supervisor module, not the standby supervisor module. The install all command is the recommended method for software upgrades because it performs configuration compatibility checks and BIOS upgrades automatically. In contrast, changing the boot variables and reloading the device bypasses these checks and the BIOS upgrade and therefore is not recommended.

Failure to do so can cause a diagnostic failure on the line card and no TCAM space to be allocated. When you upgrade from an earlier release to a Cisco NX-OS release that supports switch profiles, you have the option to move some of the running-configuration commands to a switch profile. Make sure that both vPC peers are in the same mode regular mode or enhanced mode before performing a nondisruptive upgrade. Only one device at a time is upgraded.

When the first device completes its upgrade, it unlocks its peer device. The second device then performs the upgrade process, locking the first device as it does so. During the upgrade, the two vPC devices temporarily run different releases of Cisco NX-OS; however, the system functions correctly because of its backward compatibility support. If the user executes a show command that produces more output and keeps the session on for more than 3 minutes, the following warning message may be displayed on the console.

There is no functionality impact or traffic loss due to this issue. Occasionally, while the switch is operationally Up and running, the Device not found logs are displayed on the console. This issue is observed because the switch attempts to find an older ASIC version and the error messages for the PCI probe failure are enabled in the code.

This label is printed as part of the image during the install operation from any release prior to Cisco NX-OS Release 7. See the following example. ISSU is blocked if boot poap enable is configured. To avoid traffic loss, it is recommended to increase the routing protocol's graceful restart timer to higher value. The recommended value of the graceful restart timer is seconds.

You can further increase or decrease this value based on the scale of the configuration. The following tables identify the platforms supporting standard and enhanced ISSU, and the release when the support was introduced. You can use the show spanning-tree issu-impact command to verify if the switch meets this criteria.

Cisco Nexus , , and with dual supervisor modules, a minimum of two system controllers, two fabric modules, and any of the following line cards:. Before attempting to downgrade to an earlier software release, follow these guidelines:. The only supported method of downgrading a Cisco Nexus Series switch is to utilize the install all command.

Changing the boot variables, saving the configuration, and reloading the switch is not a supported method to downgrade the switch. The configuration change is required because the default ing-netflow TCAM region in 9. Software downgrades should be performed using the install all command.

TAM was updated to version-7 in 9. Only Release 9. On devices with dual supervisor modules, both supervisor modules must have connections on the console ports to maintain connectivity when switchovers occur during a software downgrade. Cisco NX-OS automatically installs and enables the guest shell by default. As a best practice, remove the guest shell with the guestshell destroy command before downgrading to an earlier Cisco NX-OS image.

You must delete the switch profile if configured when downgrading from a Cisco NX-OS release that supports switch profiles to a release that does not. Software downgrades are disruptive. Upgrading from a 7. The following section describe the upgrade paths required. These patches are available for each respective release and can be downloaded using the links below.

Failing to follow this procedure could require console access in order to recover the switch after the upgrade. These patches are only for upgrading. After the upgrade, the patch is automatically removed. If you decide not to upgrade after installing the patches, do not deactivate it. To install these patches prior to upgrading using the install all command, follow the instructions shown below. An example is demonstrated below with an NX-OS software patch and upgrade from 7.

Proceed with an NX-OS software upgrade to the desired target release with the install all command. Before you enable the LXC mode, ensure that the installed licenses do not include the string in the license file. Optional show boot mode. Reloads the device. When prompted, press Y to confirm the reboot.

Make sure to choose the non-disruptive option if you want to perform an enhanced or regular ISSU. Read the release notes for the software image file for any exceptions to this upgrade procedure. We recommend that you have the image file for at least one previous release of the Cisco NX-OS software on the device to use if the new image file does not load successfully. If you need more space on the active supervisor module, delete unnecessary files to make space available.

If you need more space on the standby supervisor module, delete any unnecessary files to make space available. Log in to Cisco. Copy the software image to the active supervisor module using a transfer protocol. The following example uses SCP and bootflash:. The compact keyword compacts the NX-OS image before copying the file to the supervisor module. If you attempt compaction with any other protocol, the system returns the following error:. Check the impact of upgrading the software before actually performing the upgrade.

By default, the software upgrade process is disruptive. You must configure the non-disruptive option to perform an ISSU. Upgrade the Cisco NX-OS software using the install all nxos bootflash: filename [ no-reload non-disruptive non-interruptive serial ] command.

This option skips all error and sanity checks. Optional Log in and verify that the device is running the required software version. Optional If necessary, install any licenses to ensure that the required features are available on the device. The following list summarizes the upgrade process on a switch in a vPC topology that holds either the Primary or Operational Primary vPC roles.

Steps that differ from a switch upgrade in a non-vPC topology are in bold. In vPC topologies, the two peer switches must be upgraded individually. An upgrade on one peer switch does not automatically update the vPC peer switch.

The install all command issued on the vPC primary switch triggers the installation upgrade. The configuration is locked on both vPC peer switches. The vPC primary switch is running the upgraded version, and the vPC secondary switch is running the original software version. The following list summarizes the upgrade process on a switch in a vPC topology that holds either the Secondary or Operational Secondary vPC roles.

The install all command issued on the vPC secondary switch triggers the installation upgrade. The configuration is unlocked on the primary and secondary switches. Read the release notes for the software image file for any exceptions to this downgrade procedure. Verify that the image file for the downgrade is present on the active supervisor module bootflash:.

If the software image file is not present, log in to Cisco. If you need more space on the active or standby supervisor module bootflash:, use the delete command to remove unnecessary files. During the life of a Cisco Nexus switch, many upgrade procedures can be performed. Upgrades can occur for maintenance purposes or to update the operating system to obtain new features. Over time, switches may be updated on numerous occasions. Viewing the types of upgrades and when they occurred can help in troubleshooting issues or simply understanding the history of the switch.

The stored upgrade history types are:. The output displays any upgrade activity that previously occurred on the switch and defines the start and end times for each event. The following is an example output of the show upgrade history command:. Skip to content Skip to search Skip to footer. Book Contents Book Contents. Find Matches in This Book. Log in to Save Content.

Updated: December 21, Note Another type of binary file is the software maintenance upgrade SMU package file. Note Cisco also provides electronic programmable logic device EPLD image upgrades to enhance hardware functionality or to resolve known hardware issues. Figure 1. Parallel Upgrade Process for Cisco Nexus Series Switches The steps for the parallel upgrade process on Cisco Nexus Series switches are: First the supervisors are upgraded This procedure requires a switchover.

The user also has the option to choose a serial upgrade using the CLI. Note The minimum requirement for a modular Cisco Nexus Series switch undergoing ISSU is two supervisors, two system controllers, and two fabric modules. See the following sample configuration for more information: switch config boot mode lxc Using LXC boot mode Please save the configuration and reload system to switch into the LXC mode.

Note In-service software downgrades ISSDs , also known as nondisruptive downgrades, are not supported. Do not use the Nexus series compressed image on Nexus series The following limitation applies to software upgrades from 7.

No interface should be in a spanning-tree designated forwarding state. Also, bridge assurance should not be configured on any interface of the Cisco Nexus device. The following is a list of things you must check:. Domain Manager—As part of the installation process, domain manager checks if the fabric is in a stable state. If the fabric is not stable, the installation will abort. If any application is holding a CFS lock, the installation will abort. Zone Server— The installation process aborts if a zone merge or zone change request is in progress.

Services that depend on the inband and management ports are impacted during this time. Because all Network Management services are disabled during this time, this behavior is consistent. After the reboot, NTP session are reestablished based on the saved startup configuration. During an ISSU, the control plane is offline for up to 80 seconds. Any state changes in the network during this time are not processed. Depending on the change, the impact may vary. We recommend that you ensure a stable fabric during an ISSU.

See the following table for other ISSU impacts. A peer switch zone change request is not answered by the switch undergoing an ISSU. Any topology changes during this time are also not acted upon until the ISSU completes. IEEE IGMP does not disrupt existing flows of multicast traffic that are already present, but new flows are not learned and are dropped until an ISSU completes.

New router ports or changes to router ports are not detected during this time. Manual configurations are ignored during this time. During an ISSU, the time-to-live value is increased seconds if it is less than the recommended timeout value. The configuration is ignored if manually specified.

To avoid link down to link up transitions during the control plane outage time, the laser is turned off for administratively up ports that are operationally down. This situation occurs during the ISSU reboot starting state when the switch and the FEX applications stop communicating with each other. After the ISSU reboot and a stateful restart, the laser is turned back on. This action prevents the link state from transitioning from down to up during an ISSU.

Note The switch might reload at this time and cause a traffic disruption if the upgrade is not an ISSU. The following table lists the show commands that identify the impact or potential problems that may occur when performing an ISSU. Displays incompatible configurations on the current system that will impact the upgrade version. Displays the facility logging severity level configuration.

Logging levels for all processes must be set at 5 or below when performing an ISSU. Processes with a logging level greater than 5 are not displayed when you enter the show install all impact command. Displays information that describes the impact of the upgrade on each Fabric Extender including the current and upgrade-image versions.

This command also displays if the upgrade is disruptive or not and if the Fabric Extender needs to be rebooted and the reason why. Displays the spanning-tree configuration and whether or not there are potential STP issues. Displays the port priority information and whether or not there are potential issues. You can also perform the following tasks to identify potential problems before they occur:. Use the show lacp issu-impact command to display if any port or a peer switch is configured in rate fast mode.

The ISSU process is triggered when you enter the install all command. This section describes the sequence of events that occur when you upgrade a single Cisco Nexus device or a single Cisco Nexus device that is connected to one or more FEXs. The following table shows an overview of the upgrade process. Table 7 Upgrade Process At-a-Glance. Log in to the first Cisco Nexus device.

We recommend that you log in to the console port. In vPC topologies, the first upgrade can be performed on either the primary or secondary switch in the topology. Log in to Cisco. To log in to Cisco. Enter your Cisco username and password. Choose and download the kickstart and system software files to the server. Verify that the required space is available in the bootflash: directory for the image file s to be copied.

If you need more space in the bootflash: directory, delete unnecessary files to make space available. Copy the Cisco NX-OS kickstart and system images to the bootflash using a transfer protocol such as ftp:, tftp:, scp:, or sftp. Compare the file sizes of the images that were transferred using the dir bootflash command.

The file sizes of the images obtained from Cisco. Complete the above steps for each Cisco Nexus device in the topology. Enter the show incompatibility command to verify that the target image is feature-wise compatible with the current image.

Enter the show install all impact command to identify the upgrade impact. Enter the show spanning-tree issu-impact command to display the impact of the upgrae impact. Enter the show lacp issue-impact command to display the impact of the upgrade. Enter the show fex command to verify that all the FEXs are online. Enter the show vpc role command to verify the vPC switch role. Peruse the installer impact analysis and accept to proceed.

The Installer for the Cisco Nexus upgrades the software. The switch will now run a new version of the software. Enter the show install all status command to verify the status of the installation. You can copy configuration files from an external flash memory device. Insert the external flash memory device into the active supervisor module. Optional Displays the files on the external flash memory device.

Copies the image from an external flash memory device into the bootflash. The filename argument is case sensitive. Copies the running configuration from an external flash memory device. Optional Copies the running configuration from an external flash memory device to the bootflash.

Optional Copies the running configuration to the startup configuration. You can recover the startup configuration on your Cisco NX-OS device by downloading a new startup configuration file saved on an external flash memory device.

Copies a saved configuration from an external flash memory device to the startup configuration. Optional Copies a saved configuration from an external flash memory device to the bootflash. The following list summarizes the upgrade process in a non-vPC topology:. The install all command triggers the installation upgrade. The compatibility checks display the impact of the upgrade. The installation proceeds or not based on the upgrade impact.

The current state is saved. The system unloads and runs the new image. The stateful restart of the system software and application occurs. The installer resumes with the new image. The FEXs are upgraded sequentially. The installation completes. The following list summarizes the upgrade process on a primary switch in a vPC topology. Steps that differ from a switch upgrade in a non-vPC topology are in bold.

Note In vPC topologies, the two peer switches must be upgraded individually. An upgrade on one peer switch does not automatically update the vPC peer switch. The install all command issued on the vPC primary switch triggers the installation upgrade. The configuration is locked on both vPC peer switches. The installation is complete. When the installation is complete, the vPC primary switch and the FEXs that are connected to the primary switch are upgraded.

The vPC primary switch is running the upgraded version and the vPC secondary switch is running the original software version. The following list summarizes the upgrade process on a secondary switch in a vPC topology. The install all command issued on the vPC second switch triggers the installation upgrade.

Note The dual-homed FEXs were upgraded by the primary switch. The configuration is unlocked on the primary and secondary switches. Note Doing a disruptive upgrade or downgrade between incompatible images is not supported with the autoconfig feature. See CSCvb for details. For FEX configurations, prior to the downgrade, the configuration must be converted if not already used to use FEX pre-provisioning configuration.

The following lists the situations where a nondisruptive ISSU might not be possible when upgrading a Cisco Nexus device:. Perform the following steps to restore the configuration if the configurations contain interface breakout or unified port configurations:. Use the default interface command to restore the default configurations of the breakout interfaces. Save the running configuration to startup configuration using the copy running-config startup-config command. In case of VPC, downgrade the primary switch first and then the secondary switch.

After the switch is up, power-off and power-on the module for the interface breakout to be effective. If the breakout is configured on Baseboard module, save the running configuration to startup configuration using the copy running-config startup-config command and then reload the switch again. If breakout is not configured on the Baseboard, then an additional reload is required if running configuration contains hardware profile route resource service-template.

Verify if all the interfaces are up and traffic is resumed. You can choose to do a disruptive upgrade if one of the ISSU conditions are not met. One additional reason where you might choose to do a disruptive upgrade is when FEXs are upgraded in a rolling fashion one FEX at a time , which requires a longer maintenance window.

With a disruptive upgrade, all the connected FEXs are upgraded simultaneously, so the maintenance window can be shorter. If you need a shorter maintenance window with traffic disruption , you can force a disruptive upgrade even if an ISSU can be leveraged. It is important to note the possibility of an outage if you do a disruptive upgrade. You can also add the force keyword at the end of the install all command as follows:.

The reload is a cold reboot that brings down the control plan and the data plane. The reload causes disruptions to the connected servers and hosts. When one of the vPC switches is being reset during the upgrade process, all the server traffic can flow through its vPC peer. The following figures show topologies in which the access layer includes a vPC configuration to hosts or downstream switches.

To upgrade the access layer without a disruption to hosts, follow these tasks:. Note Flows that are forwarded to a switch during an upgrade on the switch, will failover to the second switch. Also, flows are redistributed when vPC peers are active. The traffic disruption is limited to the time required for the server or host to detect the link-down and link-up events and to redistribute the flows.

A disruptive upgrade causes a switch and connected FEXs to reload. The time required for a FEX to reload is less than the time required for a switch to reload. When hosts are connected to a dual-homed FEX, it is possible to keep the traffic disruption of the hosts to same time as required by FEX to reload approximately seconds , instead of the time required for an upgrade of the entire access layer.

The following figure shows a dual-homed FEX topology in which the access layer includes a vPC configuration to hosts or downstream switches. Note The following dual-homed FEX procedure is supported only for an upgrade and not for a downgrade. Upgrade the vPC primary switch with the new image using the install all kickstart image system image command.

During the upgrade process, the switch is reloaded. When the switch is reloaded, only singled-homed FEXs connected to the switch are reloaded and dual-homed FEXs are not reloaded. Servers connected to the dual-homed FEXs retain network connectivity through the vPC secondary switch. Step 2 Verify that the upgrade of the vPC primary switch is completed successfully. At the completion of the upgrade, the vPC primary switch restores vPC peering.

The servers connected to the dual-homed FEXs will lose connectivity. Step 4 Wait for the FEXs to reload. Step 5 Upgrade the vPC secondary switch with the new image using the install all kickstart image system image command.

Step 6 Verify that the upgrade of the vPC secondary switch is completed successfully. At the completion of the upgrade, the vPC secondary switch restores vPC peering. Dual-homed FEXs connect to both the peer switches and start forwarding traffic. Step 1 Log in to Cisco. Note Unregistered Cisco. Navigate to the software downloads for Cisco Nexus devices.

Links to the download images for the switch are listed. Step 2 Choose and download the kickstart and system software files to a local server. Step 3 Verify that the required space is available in the bootflash: directory for the image file s to be copied. We recommend that you keep the kickstart and system image files for at least one previous software release to use if the new image files do not load successfully.

Step 4 Optional If you need more space on the bootflash, delete unnecessary files to make space available. Perform this step on both the switches in a vPC pair. Step 7 Enter the show install all impact command to validate the upgrade process and the components being upgraded.

Step 8 Enter the install all kickstart image system image command on the vPC primary switch. During the software upgrade on the primary switch, you can view the FEX upgrade progress using the vPC secondary switch see the bold output :. Step 9 Ensure that the upgrade on vPC primary switch is completed. Use the show version command to verify the upgrade on vPC primary switch.

Note Only the vPC primary switch shows that the Fabric Extender is online because the vPC secondary switch does not have the new image. When all the Fabric Extenders are loaded, go to the next step. To upgrade the vPC secondary switch, follow Step 2 to Step 9. Use the show fex command to view the FEX status. Table 8 lists the show commands that are used to monitor installation upgrades. Table 8 Monitoring the Upgrade Process.

Displays the applications that failed during an installation and why the installation failed. Displays detailed logs of the last installation-related command. Displays detailed logs of the last five installation-related commands, from the oldest to the newest logs. Displays the system and configuration information that you can provide to the Cisco Technical Assistance Center when reporting a problem. The following example shows the output from the show install all status command:.

Note that the downgrades are disruptive. You can use the show incompatibility system command to ensure that there are no feature incompatibilities between the current release and the target release. Note When you perform a disruptive downgrade using the install-all command, and the fabric mode is set to 40 Gigabit mode, the fabric mode will revert to 10 Gigabit mode.

To restore the fabric mode to 40 Gigabit mode, configure the fabric mode to 40 Gigabit and reload the device. After FEX pre-provisioning is done, perform the following steps to restore the configuration if the configurations contain interface breakout or unified port configurations:. In case of vPC, downgrade the primary switch first and then the secondary switch.

Note Before you downgrade to a specific release, check the release notes for the current release installed on the switch to ensure that your hardware is compatible with the specific release. Some common causes for ISSU failure are as follows:.

Updated: July 28, Upgrade Guidelines When upgrading system software, follow these guidelines: Configuration changes You cannot enter global configuration mode during an upgrade. There are no active configuration sessions. Table 1 install all Commands and Output Terminology Term. You can receive descriptive information about the intended changes to your system before you continue with the installation.

For example, it identifies potential disruptive upgrades. Warning: please do not remove or power off the module at this time. Note: Power-seq upgrade needs a power-cycle to take into effect. This example shows how to determine the vPC operational role of the switch: switch-2 show vpc brief. Peer status : peer adjacency formed ok. Configuration consistency status : success. Per-vlan consistency status : success. Type-2 consistency status : success.

Number of vPCs configured : Dual-active excluded VLANs : -. Graceful Consistency Check : Enabled. Install pending. You must delete the switch profile if configured when downgrading from a Cisco NX-OS release that supports switch profiles to a release that does not.

Software downgrades are disruptive. Upgrading from a 7. The following section describe the upgrade paths required. These patches are available for each respective release and can be downloaded using the links below. Failing to follow this procedure could require console access in order to recover the switch after the upgrade. These patches are only for upgrading. After the upgrade, the patch is automatically removed.

If you decide not to upgrade after installing the patches, do not deactivate it. To install these patches prior to upgrading using the install all command, follow the instructions shown below. An example is demonstrated below with an NX-OS software patch and upgrade from 7. Proceed with an NX-OS software upgrade to the desired target release with the install all command. Before you enable the LXC mode, ensure that the installed licenses do not include the string in the license file. Optional show boot mode.

Reloads the device. When prompted, press Y to confirm the reboot. Make sure to choose the non-disruptive option if you want to perform an enhanced or regular ISSU. Read the release notes for the software image file for any exceptions to this upgrade procedure. We recommend that you have the image file for at least one previous release of the Cisco NX-OS software on the device to use if the new image file does not load successfully.

If you need more space on the active supervisor module, delete unnecessary files to make space available. If you need more space on the standby supervisor module, delete any unnecessary files to make space available. Log in to Cisco. Copy the software image to the active supervisor module using a transfer protocol.

The following example uses SCP and bootflash:. The compact keyword compacts the NX-OS image before copying the file to the supervisor module. If you attempt compaction with any other protocol, the system returns the following error:. Check the impact of upgrading the software before actually performing the upgrade.

By default, the software upgrade process is disruptive. You must configure the non-disruptive option to perform an ISSU. Upgrade the Cisco NX-OS software using the install all nxos bootflash: filename [ no-reload non-disruptive non-interruptive serial ] command. This option skips all error and sanity checks.

Optional Log in and verify that the device is running the required software version. Optional If necessary, install any licenses to ensure that the required features are available on the device. The following list summarizes the upgrade process on a switch in a vPC topology that holds either the Primary or Operational Primary vPC roles.

Steps that differ from a switch upgrade in a non-vPC topology are in bold. In vPC topologies, the two peer switches must be upgraded individually. An upgrade on one peer switch does not automatically update the vPC peer switch. The install all command issued on the vPC primary switch triggers the installation upgrade. The configuration is locked on both vPC peer switches. The vPC primary switch is running the upgraded version, and the vPC secondary switch is running the original software version.

The following list summarizes the upgrade process on a switch in a vPC topology that holds either the Secondary or Operational Secondary vPC roles. The install all command issued on the vPC secondary switch triggers the installation upgrade. The configuration is unlocked on the primary and secondary switches. Read the release notes for the software image file for any exceptions to this downgrade procedure.

Verify that the image file for the downgrade is present on the active supervisor module bootflash:. If the software image file is not present, log in to Cisco. If you need more space on the active or standby supervisor module bootflash:, use the delete command to remove unnecessary files.

During the life of a Cisco Nexus switch, many upgrade procedures can be performed. Upgrades can occur for maintenance purposes or to update the operating system to obtain new features. Over time, switches may be updated on numerous occasions. Viewing the types of upgrades and when they occurred can help in troubleshooting issues or simply understanding the history of the switch. The stored upgrade history types are:. The output displays any upgrade activity that previously occurred on the switch and defines the start and end times for each event.

The following is an example output of the show upgrade history command:. Skip to content Skip to search Skip to footer. Book Contents Book Contents. Find Matches in This Book. Log in to Save Content. PDF - Complete Book 2.

Updated: December 21, Note Another type of binary file is the software maintenance upgrade SMU package file. Note Cisco also provides electronic programmable logic device EPLD image upgrades to enhance hardware functionality or to resolve known hardware issues.

Figure 1. Parallel Upgrade Process for Cisco Nexus Series Switches The steps for the parallel upgrade process on Cisco Nexus Series switches are: First the supervisors are upgraded This procedure requires a switchover. The user also has the option to choose a serial upgrade using the CLI.

Note The minimum requirement for a modular Cisco Nexus Series switch undergoing ISSU is two supervisors, two system controllers, and two fabric modules. See the following sample configuration for more information: switch config boot mode lxc Using LXC boot mode Please save the configuration and reload system to switch into the LXC mode.

Note In-service software downgrades ISSDs , also known as nondisruptive downgrades, are not supported. Do not use the Nexus series compressed image on Nexus series The following limitation applies to software upgrades from 7. User can change vrrpv3 timers to seconds or fine tune these timers based on upgrade time on all Vrrp Peers to avoid Vrrp State transitions.

User can change vrrp timers to seconds or fine tune these timers based on upgrade time on all Vrrp Peers to avoid Vrrp State transitions. Schedule the upgrade when your network is stable and steady. In general, ISSUs are supported for the following: From a major release to any associated maintenance release.

From the last two maintenance releases to the next two major releases. From an earlier maintenance release to the next two major releases. Please wait. Upgrade Paths Upgrading from a 7. Upgrade Paths to Release 9. Caution Failing to follow this procedure could require console access in order to recover the switch after the upgrade.

Step 8 Copy the software image to the active supervisor module using a transfer protocol.

Copy complete. Note Software image compaction is only supported on Cisco Nexus series platform switches. Default upgrade is not hitless By default, the software upgrade process is disruptive. Step 11 Save the running configuration to the startup configuration. Note When you use install all with no-reload option, the saved configuration cannot be used before you reload the device.

Note If you enter the install all command without specifying a filename, the command performs a compatibility check, notifies you of the modules that will be upgraded, and confirms that you want to continue with the installation. If you choose to proceed, it installs the NX-OS software image that is currently running on the switch and upgrades the BIOS of various modules from the running image, if necessary.

Step 13 Optional Display the entire upgrade process. Note In vPC topologies, the two peer switches must be upgraded individually. The compatibility checks display the impact of the upgrade. The installation proceeds or not based on the upgrade impact. The current state is saved. The system unloads and runs the new image.

The stateful restart of the system software and application occurs. The installer resumes with the new image. The installation is complete. When the installation is complete, the vPC primary switch is upgraded. Note The vPC primary switch is running the upgraded version, and the vPC secondary switch is running the original software version.

Downgrading to an Earlier Software Release Note If an error message appears during the downgrade, the downgrade will fail because of the reason indicated. Procedure Step 1 Read the release notes for the software image file for any exceptions to this downgrade procedure.

Step 3 Verify that the image file for the downgrade is present on the active supervisor module bootflash:. Note If you need more space on the active or standby supervisor module bootflash:, use the delete command to remove unnecessary files. Step 5 Copy the software image to the active supervisor module using a transfer protocol. Step 7 Disable any features that are incompatible with the downgrade image. Step 8 Check for any hardware incompatibilities.
