Cisco Nexus 7000 Series NX-OS Software Upgrade and Downgrade Guide

This document describes how to upgrade or downgrade the Cisco NX-OS software.

About Software Images

Each device is shipped with the Cisco NX-OS software. The Cisco NX-OS software consists of two images—the kickstart image and the system image.

The software image install procedure is dependent on the following factors:

  • Software images—The kickstart and system image files reside in directories or folders that you can access from the Cisco NX-OS software prompt.

  • Image version—Each image file has a version.

  • Flash disks on the device—The bootflash: resides on the supervisor module and the CompactFlash disk is inserted into the slot0:, usb1, or usb2: device.

  • Supervisor modules—There are single or dual supervisor modules.


Note

On devices with dual supervisor modules, both supervisor modules must have connections on the console ports to maintain connectivity when switchovers occur during upgrades and downgrades. See the Cisco Nexus 7000 Series Hardware Installation and Reference Guide.


About In-Service Software Upgrades on Devices with Dual Supervisor Modules

The Cisco NX-OS software supports in-service software upgrades (ISSUs) on devices with dual supervisor modules. An ISSU can update the software images on your device without disrupting data traffic. Only control traffic is disrupted. If an ISSU will cause a disruption of data traffic, the Cisco NX-OS software warns you before proceeding so that you can stop the upgrade and reschedule it to a time that minimizes the impact on your network.

An ISSU updates the following images:

  • Kickstart image

  • System image

  • Supervisor module BIOS

  • Data module image

  • Data module BIOS

  • Connectivity management processor (CMP) image

  • CMP BIOS


    Note

    CMP is a Supervisor 1 only feature.

Note

CMP is a Supervisor 1 only feature.


Virtualization Support

When you upgrade the Cisco NX-OS software, you upgrade the software for all virtual device contexts (VDCs) on the physical device. You cannot upgrade the Cisco NX-OS software for an individual VDC.

Parallel Upgrade

Parallel Upgrade with I/O Modules

Starting with Cisco NX-OS Release 5.2(1), multiple linecards can be simultaneously upgraded, and the infrastructure support is available. This decreases the ISSU time when compared with an ISSU upgrade that is done serially (one card at a time).

To start a parallel upgrade, use the following command: install all kickstart image system image parallel

Up to three linecards can be upgraded in parallel with this command. During the upgrade process, the upgrade of the linecards is displayed in the output as follows:

Non-disruptive upgrading.
[#                   ]   0%
Module 5 upgrade completed successfully.
.

Module 3 upgrade completed successfully.

.

Non-disruptive upgrading.
[####################] 100% -- SUCCESS

Note

This command will be ignored for a downgrade to a release below Cisco NX-OS Release 5.2.(1).

Parallel Upgrade with Fabric Extenders

Beginning with Cisco NX-OS Release 6.1(1), a parallel upgrade on the Fabric Extenders (FEX) is supported if the user types the parallel keyword in the command. You can perform a parallel upgrade of 10 FEXs at a time.

For releases prior to Cisco NX-OS Release 6.1(1), only a serial upgrade of FEXs is supported. The upgrade process switches to a serial upgrade even for the I/O modules present. Even if the user types the parallel keyword in the command, the upgrade will be a serial upgrade.

Prerequisites for Upgrading the Cisco NX-OS Software

Upgrading the Cisco NX-OS software has the following prerequisite:

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. On a device with a single supervisor module, the Cisco NX-OS software deletes the active configuration session without warning when you reload the device.

Use the show configuration session summary command to verify that you have no active configuration sessions.

For more information on configuration sessions, see the Cisco Nexus 7000 Series NX-OS System Management Configuration Guide.

Cisco NX-OS Software Upgrade Guidelines


Note

Cisco Nexus 7000 Series NX-OS Release Notes contain specific upgrade guidelines for each release. See the Release Notes document for the target upgrade release before starting the upgrade.


Before attempting to use ISSU to upgrade to any software image version, follow these guidelines:

  • Scheduling

    Schedule the upgrade when your network is stable and steady. Ensure that everyone who has access to the device or the network is not configuring the device or the network during this time. You cannot configure a device during an upgrade.

  • Space

    Verify that sufficient space is available in the location where you are copying the images. This location includes the active and standby supervisor module bootflash: (internal to the device). Internal bootflash: has approximately 250 MB of free space available.

  • Hardware

    Avoid power interruption during any install procedure, which can corrupt the software image.

  • Connectivity to remote servers

    • Configure the IPv4 address or IPv6 address for the 10/100/1000 BASE-T Ethernet port connection (interface mgmt0).

    • Ensure that the device has a route to the remote server. The device and the remote server must be in the same subnetwork if you do not have a router to route traffic between subnets.

  • Software images

    • Ensure that the specified system and kickstart images are compatible with each other.

    • If the kickstart image is not specified, the device uses the current running kickstart image.

    • If you specify a different system image, ensure that it is compatible with the running kickstart image.

    • Retrieve the images in one of two ways:

      Locally
      Images are locally available on the switch.
      Remotely
      Images are in a remote location and you specify the destination using the remote server parameters and the filename to be used locally.
    • PowerOn Auto Provisioning (POAP)

      • To support POAP to be more secure, ensure that DHCP snooping is enabled; and set the firewall rules to block unintended or malicious DHCP servers.

In-Service Software Upgrade (ISSU)

To perform an ISSU upgrade to Cisco NX-OS Release 8.0(1) and later releases, follow these steps:

  1. Enter the show running-config aclmgr inactive-if-config command for all VDCs.

  2. Enter the clear inactive-config acl command for all VDCs.

  3. If the configuration has any mac packet-classify configurations on any interfaces, remove all of the configurations by entering the no mac packet-classify command.

  4. Start the ISSU procedure.

In-Service Software Upgrade (ISSU) Caveats

  • When you perform ISSU to upgrade to a new Cisco NX-OS release, the default CoPP policy for the new release is not applied. Because you might have your own configured CoPP policy and want to continue using it, the policy for the earlier release continues to be applied. However, if you have not modified the default CoPP policy in earlier versions, it is recommended that when you install Cisco NX-OS Release 5.2 or later releases, you should apply the latest default CoPP policy for the upgrading version by using the copp profile [strict | moderate | lenient] command. This action removes the previous policy and applies a new CoPP policy. Note that reapplying copp profile configuration removes CoPP momentarily on the chassis for the new configuration to take into effect. Hence, this needs to be done in a maintained environment.

  • ISSU upgrade from Cisco NX-OS 7.3.x releases to Cisco NX-OS Release 8.0(1) with RISE configuration:

    • RISE configuration must be removed prior to starting your upgrade to Cisco NX-OS Release 8.0(1). ISSU performs compatibility check and blocks the upgrade if RISE is configured.

      • If the RISE feature is not configured, there is no impact on the ISSU.

      • If the RISE feature is configured you will be prompted to remove this feature in order to proceed with the ISSU. You can proceed with the upgrade only after you disable this feature.

        • Sample CLI Output

        "Running-config contains configuration that is incompatible with the new image (strict incompatibility).
        Please run 'show incompatibility-all system <image>' command to find out which feature needs to be disabled.”.
        Pre-upgrade check failed. Return code 0x40930029 (Current running-config is not supported by new image).

  • ISSU upgrade from Cisco NX-OS 7.3.x releases to Cisco NX-OS Release 8.0(1) with VXLAN configuration in a vPC setup:

    ISSU upgrade from Cisco NX-OS 7.3.x releases to Cisco NX-OS Release 8.0(1) with VXLAN configuration in a vPC setup can result in a traffic loss when the second vPC peer is upgraded.

    The following upgrade steps are recommended as the workaround for this issue:

    • Shutdown vPC on the vPC secondary and reload with 8.0(1).

    • Perform no shut vpc after the system is operational.

    • Perform a vPC role change so that vPC secondary becomes a vPC primary.

    • Shutdown vPC on the other peer that is still running 7.3 release and reload with 8.0(1).

    • Perform no shut vpc after the system is operational.

    • Optionally, a vPC role change can be performed to get the latest peer back to vPC primary.

  • If ISSU fails during a FEX module upgrade, you need to clear the flash as per the following steps and then proceed with the upgrade:

    • rlogin to the failing FEX—rlogin 192.0.2.<FEX-ID> -l root

    • umount /mnt/cfg

    • flash_eraseall /dev/mtd5

    • mount -t jffs2 -rw /dev/mtdblock5 /mnt/cfg

    The mount command enables you to mount a file from a source folder to a destination folder.

  • FCoE FEX

    • Post ISSU you need to change port-channel load-balance for FEX, from default VDC, in order to apply load-balancing for SAN traffic.

      Device(config)# port-channel load-balance src-dst mac fex 101

    • You can revert back to default load-balance after changing the load-balance for FEX.

    • When you perform an ISSU from Cisco NX-OS 7.3(2)D1(1) and earlier releases, and from Cisco NX-OS 8.0 release to Cisco NX-OS Release 8.1.x, then reload the FEXs after the ISSU to avoid any FCoE traffic loss.

  • For details on ISSU for other earlier releases refer to the following: Cisco Nexus 7000 Series NX-OS Release Notes, Release 7.2

  • For multi-hop ISSU scenario for releases earlier than Cisco NX-OS Release 7.2(0) refer to the following:

Note

Non-ISSU upgrades are also referred to as cold boot upgrade.


To perform a non-ISSU upgrade (cold boot upgrade) to Cisco NX-OS Release 8.0(1) and later releases from any prior supported releases in the above table follow these steps:

  1. Change the boot variable.

    Example for Cisco NX-OS Release 8.2(1):

    boot kickstart bootflash:/n7000-s2-kickstart.8.2.1.bin sup-1
    boot system bootflash:/n7000-s2-dk9.8.2.1.bin sup-1
    boot kickstart bootflash:/n7000-s2-kickstart.8.2.1.bin sup-2
    boot system bootflash:/n7000-s2-dk9.8.2.1.bin sup-2

    Example for Cisco NX-OS Release 8.1(1):

    boot kickstart bootflash:/n7000-s2-kickstart.8.1.1.bin sup-1
    boot system bootflash:/n7000-s2-dk9.8.1.1.bin sup-1
    boot kickstart bootflash:/n7000-s2-kickstart.8.1.1.bin sup-2
    boot system bootflash:/n7000-s2-dk9.8.1.1.bin sup-2

    Example for Cisco NX-OS Release 8.0(1):

    boot kickstart bootflash:/n7000-s2-kickstart.8.0.1.bin sup-2 
    boot system bootflash:/n7000-s2-dk9.8.0.1.bin sup-1
    boot kickstart bootflash:/n7000-s2-kickstart.8.0.1.bin sup-2 
    boot system bootflash:/n7000-s2-dk9.8.0.1.bin sup-2
  2. Enter the copy running-config startup-config vdc-all command.

  3. Enter the reload command to reload the switch.


Note

Allow time after the reload for the configuration to be applied.


Reload based NXOS downgrades involve rebuilding the internal binary configuration from the text-based startup configuration. This is done to ensure compatibility between the binary configuration and the downgraded software version. As a result, certain specific configuration may be missing from the configuration, after downgrade, due to ASCII replay process. This would include FEX HIF port configuration and VTP database configuration. Furthermore, NX-OS configurations that require VDC or switch reload to take effect may require additional reload when applied during the downgrade process. Examples of this include URIB/MRIB shared memory tuning, custom reserved VLAN range and Fabricpath Transit Mode feature. In order to mitigate this during downgrade, you should copy your full configuration to bootflash/tftpserver.

Feature Support:

Any features introduced in a release must be disabled before downgrading to a release that does not support those features.

Unsupported Modules:

When manually downgrading from a Cisco NX-OS Release to an earlier release, first power down all modules that are unsupported in the downgrade image. Then, purge the configuration of the unsupported modules using the purge module module_number running-config command.

For complete instructions on upgrading your software, see the Cisco Nexus 7000 Series NX-OS Upgrade Downgrade Guide.

Non-In-Service Software Upgrade (Non-ISSU)/Cold Boot Upgrade Caveats

  • When you perform a cold boot upgrade to a new Cisco NX-OS release, the default CoPP policy for the new release is not applied. Because you might have your own configured CoPP policy and want to continue using it, the policy for the earlier release continues to be applied. However, if you have not modified the default CoPP policy in earlier versions, it is recommended that when you install Cisco NX-OS Release 5.2 or later releases, you should apply the latest default CoPP policy for the upgrading version by using the copp profile [strict | moderate | lenient] command. This action removes the previous policy and applies a new CoPP policy. Note that reapplying copp profile configuration removes CoPP momentarily on the chassis for the new configuration to take into effect. Hence, this needs to be done in a maintained environment

    .

Cold boot/Reload upgrades from Cisco NX-OS 7.3.x releases to Cisco NX-OS Release 8.0(1) and Cisco NX-OS Release 8.1(1) with RISE Configuration

  • RISE configuration must be removed prior to starting your upgrade to Cisco NX-OS Release 8.0(1)/Cisco NX-OS Release 8.1(1). ISSU performs compatibility check and blocks the upgrade if RISE is configured. There is no warning displayed or prevention for the reload upgrade. Therefore make sure to remove RISE configuration before the reload upgrade.

    • There is no system check to block this upgrade path.

    • Ensure that the RISE feature is disabled before attempting to upgrade to Cisco NX-OS Release 8.0(1)/Cisco NX-OS Release 8.1(1). After upgrading to Cisco NX-OS Release 8.0(1)/Cisco NX-OS Release 8.1(1), configure RISE services as required. The RISE feature configuration can be verified by using the show rise and show run services sc_engine commands.

    • If you upgrade to Cisco NX-OS Release 8.0(1)/Cisco NX-OS Release 8.1(1) with the RISE configuration, RISE services will become unstable and unmanageable.

      • Steps to identify the error condition:

        Even if the show feature command output shows RISE as enabled, no output will be displayed if you run the show rise and show run services sc_engine commands.

      • Steps to recover:

        The only way to recover from this condition is to do a reload ascii on the switch.

ASCII Configuration Replay

Saving VLAN Configuration Information:

Because a VLAN configuration can be learned from the network while the VLAN Trunking Protocol (VTP) is in a server/client mode, the VLAN configuration is not stored in the running configuration. If you copy the running configuration to a file and apply this configuration at a later point, including after a switch reload, the VLANs will not be restored. However, the VLAN configuration will be erased if the switch is the only server in the VTP domain.

The following steps list the workaround for this limitation:

  • Configure one of the clients as the server.

  • Complete the following steps:

    • Copy the VTP data file to the bootflash: data file by entering the copy vtp-datafile bootflash: vtp-datafile command.

    • Copy the ASCII configuration to the startup configuration by entering the copy ascii-cfg-file startup-config command.

    • Reload the switch with Cisco NX-OS Release 6.2(2) or a later release

      .

This limitation does not apply to a binary configuration, which is the recommended approach, but only to an ASCII configuration. In addition, this limitation applies to all Cisco NX-OS software releases for the Cisco Nexus 7000 series.

Rebind Interfaces command is not automatically executed when Replaying ASCII configuration in Cisco NX-OS Release 6.2(x):

The rebind interfaces command introduced in Cisco NX-OS Release 6.2(2) is needed to ensure the proper functionality of interfaces in certain circumstances. The command might be required when you change the module type of a VDC. However, because of the disruptive nature of the rebind interfaces command, for Cisco NX-OS Release 6.2(x) prior to Cisco NX-OS Release 6.2(8), this limitation applies only when all of the following conditions are met:

  • The ASCII configuration file is replayed in the context of the default VDC or the admin VDC, and at least one VDC has an F2e Series or an F3 Series module listed as supported module types either before or after the replay.

  • The limit-resource module-type commands listed in the ASCII configuration file requires that rebind interfaces command be executed.

The following steps list the workaround for this limitation:

  • Manually enter the rebind interfaces command wherever needed to the ASCII configuration file for replay.

  • Enter the rebind interfaces command immediately after you enter the limit-resource module-type command.

  • Ensure that the ASCII replay properly applies all interface configurations for all interfaces in the relevant VDCs.


Note

If you boot up the switch without any startup configuration, this limitation might apply to an ASCII replay. The reason is that without a startup configuration, the default VDC might still have certain interfaces automatically allocated. Because of this possibility, follow the approaches to work around the limitation.


Non In-Service Software Downgrade (non-ISSU)/Cold Boot Downgrade Steps

Instructions provided below list the steps for the cold boot (non-ISSU) downgrade. The example provided below is for a cold boot downgrade for the following:

  • A switch that is running Cisco NX-OS Release 8.2(1) and needs to reload with Cisco NX-OSRelease 6.2(8a).

  • A switch that is running Cisco NX-OS Release 8.1(1) and needs to reload with Cisco NX-OSRelease 6.2(8a).

  • A switch that is running Cisco NX-OS Release 8.0(1) and needs to reload with Cisco NX-OSRelease 6.2(12).

Refer to the ASCII Configuration Replay caveats section for specific configuration caveats.

  • Save the switch configuration.

    • Enter copy running-config bootflash:<config.txt> vdc-all command.

  • Change the boot variable to boot the target release.

  • Enter copy running-config startup-config vdc-all command to save the boot variable.

  • Enter write erase command to erase running configuration on the switch.

  • Enter reload command.

Once the switch and all the modules are up with the target image, do the following:

  • Enter the copy bootflash:<config.txt> running-config command.

  • Verify that the switch is configured correctly.

  • Replay the configuration copy to check if fex interfaces exist.

    • Enter the copy bootflash:<config.txt> running-config command.

Terminology

This table summarizes the terms used in the install all command output for checking compatibility.

Table 12. install all Command Output Terminology

Term

Definition

bootable

The module's ability to boot or not boot based on image compatibility.

impact

The type of software upgrade mechanism—disruptive or nondisruptive.

install-type

reset

Resets the module.

sw-reset

Resets the module immediately after a switchover.

rolling

Upgrades each module in sequence.

copy-only

Updates the software for BIOS, loader, or bootrom.

Commands to use

  • Verify connectivity to the remote server using the ping command.

  • Ensure that the required space is available on both the active and standby supervisor modules for the image files to be copied using the dir command.

  • Use the one-step install all command to upgrade your software. This command upgrades all modules in any Cisco NX-OS device.

  • Run only one installation on a device at a time.


    Note

    During vPC setup, the configuration is locked on the peer switch while ISSU is in progress.


  • ISSU is not supported when the vPC peers are on a single physical device but are across VDCs.

  • Do not enter another command while running the installation.

  • Do the installation on the active supervisor module, not the standby supervisor module.


    Note

    If the I/O modules are not compatible with the software image you install on the supervisor module, some traffic disruption might occur in those modules, depending on your configuration. The install all command output identifies these commands. You can choose to proceed with the upgrade or end at this point.


  • The configuration is locked during the upgrade process.

  • You can have only one instance of the install all command running.

Cisco NX-OS Software Downgrade Guidelines

  • Any features introduced in a release must be disabled before downgrading to a release that does not support those features. See the release notes for information on the new features introduced in each release.

  • In Cisco NX-OS Release 8.0(1), ISSD is not supported. You will have to perform a cold boot of the switch.

  • VPC peers can only operate dissimilar versions of the Cisco NX-OS software during the upgrade or downgrade process. Operating VPC peers with dissimilar versions, after the upgrade or downgrade process is complete, is not supported.

  • To determine incompatibility before you downgrade your software, use the following commands:
    • For hardware incompatibility—

      sh install all impact system system_name

    • For software incompatibility—

      show incompatibility-all system image_filename

Upgrading a Device with Dual Supervisor Modules

The install all command supports in-service software upgrades (ISSUs) on devices that have dual supervisor modules and performs the following actions:

  • Determines whether the upgrade will be disruptive and asks if you want to continue.

  • Ensure that you have enough space in the standby bootflash.

  • Copies the kickstart and system images to the standby supervisor module.

  • Sets the KICKSTART and SYSTEM boot variables.

  • Reloads the standby supervisor module with the new Cisco NX-OS software.

  • Reloads the active supervisor module with the new Cisco NX-OS software, which causes a switchover to the newly upgraded standby supervisor module.

  • Upgrades the line cards.

  • The Connectivity Management Processor (CMP) on both supervisors will get upgraded.

Benefits of Using the install all Command

The install all command provides the following benefits:

  • You can upgrade the entire device using just one command.

  • You can receive descriptive information on the intended changes to your system before you continue with the installation.

  • You have the option to cancel the command. You can continue or cancel when you see this question (the default is no ):

     Do you want to continue (y/n) [n] : y

  • You can upgrade the entire device using the least disruptive procedure.

  • You can see the progress of this command on the console, Telnet, and SSH screens:

    • Before a switchover process, you can only see the progress from the active supervisor module.

    • After a switchover process, you can see the progress from both the supervisor modules.

  • The install all command automatically checks the image integrity, which includes the running kickstart and system images.

  • The install all command performs a platform validity check to verify that a wrong image is not used—for example, to check if a Nexus 7000 device image is used inadvertently to upgrade a Nexus 5000 device.

  • The Ctrl-c escape sequence gracefully ends the install all command. You are prompted to confirm your decision to abort the ISSU process. If you proceed, the command sequence completes the update step in progress and returns to the device prompt. (Other upgrade steps cannot be ended using Ctrl-c.)

  • After entering the install all command, if any step in the sequence fails, the command completes the step in progress and ends.

    For example, if an I/O module fails to be updated for any reason (for example, due to an unstable network state), the command sequence disruptively updates that module and ends. In such cases, you can verify the problem on the affected switching module and upgrade the other I/O modules.

  • The show install all impact image-name command runs pre-upgrade checks against a given image and informs the user if the images are compatible for an upgrade or a downgrade.


Note

Refer to the "Supported Upgrade and Downgrade Paths" section of the Cisco Nexus 7000 Series NX-OS Release Notes to get details on the supported Cisco NX-OS release versions to which you can upgrade to or for the downgrade details.


ISSU Failure Conditions

The following situations cause the installation to fail to complete:

  • If the standby supervisor module bootflash: file system does not have sufficient space to accept the updated image.

  • If the specified system and kickstart images are not compatible.

  • If the network or device is configured while the upgrade is in progress.

  • If a Spanning Tree Protocol (STP) topology change occurs while the upgrade is in progress.

  • If the install all command is entered on the standby supervisor module.

  • If the install all command does not reference the default bootflash: in a dual supervisor module configuration.

  • If a module is removed while the upgrade is in progress.

  • If the device has any power disruption while the upgrade is in progress.

  • If the entire path for the remote server location is not specified accurately.

  • If some FEX ports are operating in LACP fast rate mode.

  • If images are incompatible after an upgrade. For example, an I/O module image may be incompatible with the system image, or a kickstart image may be incompatible with a system image. This is also identified by the show install all impact command in the compatibility check section of the output (under the Bootable column).

  • If a linecard is in failure state, the ISSU will abort.

The Cisco NX-OS software prevents most configuration changes while the install all command is in progress. However, the Cisco NX-OS software allows configuration changes from Cisco Fabric Services (CFS) and those changes may affect the ISSU.

Step 9

If you need more space on the standby supervisor module, delete any unnecessary files to make space available.


switch# delete bootflash://sup-standby/n7000-s2-kickstart.8.0.1.bin.CCO
switch# delete bootflash://sup-standby/n7000-s2-dk9.8.0.1.bin.CCO

Step 10

Copy the NX-OS kickstart and system images to the active supervisor module using a transfer protocol. You can use ftp: ,tftp: , scp: , or sftp: . The examples in this procedure use scp: .

Note 

When you download an image file, change to your FTP environment IP address or DNS name and the path where the files are located.


switch# copy scp://user@scpserver.cisco.com/downloads/n7000-s2-kickstart.8.0.1.bin n7000-s2-kickstart.8.0.1.bin
switch# copy scp://user@scpserver.cisco.com/downloads/n7000-s2-dk9.8.0.1.bin n7000-s2-dk9.8.0.1.bin

Step 11

Read the release notes for the related image file. See the Cisco Nexus 7000 Series NX-OS Release Notes.

Step 12

Save the running configuration to the startup configuration.


switch# copy running-config startup-config vdc-all

Step 13

Perform the upgrade using the install all command at the command prompt on the active supervisor module.


switch# install all kickstart n7000-s2-kickstart.8.0.1.bin system n7000-s2-dk9.8.0.1.bin

 

Note 

If the upgrade is disruptive, you can either resolve the issues that cause the disruption and repeat this step, or you can continue with the disruptive upgrade.

Step 14

After the installation operation completes, log in and verify that the device is running the required software version using the show version command.

Detailed Upgrade Procedure

This section describes the detailed procedure to upgrade to the latest Cisco NX-OS software on a device with a single supervisor.

Procedure


Step 1

Log in to the device on the console port connection.

Step 2

Log in to Cisco.com to access the links provided in this document. To log in to Cisco.com, go to the URL http://www.cisco.com/ and click Log In at the top of the page. Enter your Cisco username and password.

 

Note 

Unregistered Cisco.com users cannot access the links provided in this document.

Step 3

Access the Software Download Center using this URL: http://www.cisco.com/public/sw-center/index.shtml

Step 4

Navigate to the download site for your device.

You see links to the download images for your device.
Step 5

Select and download the kickstart and system software files to a server.

Step 6

Ensure that the required space is available in the bootflash: directory for the image file(s) to be copied.


switch# dir bootflash:
       4096    Oct 24 18:06:54 2016  lost+found/
  146701191    Aug 09 15:18:05 2016  n7000-s2-dk9.8.0.1.bin.CCO

Usage for bootflash://sup-local
 1260208128 bytes used
  579682304 bytes free
 1839890432 bytes total
switch#

Tip 
We recommend that you have the kickstart and system image files for at least one previous release of the Cisco NX-OS software on the device to use if the new image files do not load successfully.
Step 7

If you need more space on the supervisor module bootflash, delete unnecessary files to make space available.


switch# delete bootflash:n7000-s1-kickstart.7.2.0.D1.1.bin.CCO 
switch# delete bootflash:n7000-s1-dk9.7.2.0.D1.1.bin.CCO

Step 8

Copy the NX-OS kickstart and system images to the active supervisor module bootflash using a transfer protocol. You can use ftp:, tftp:, scp:, or sftp:. The examples in this procedure use scp:.

Note 

When you download an image file, change to your FTP environment IP address or DNS name and the path where the files are located.


switch# copy scp://user@scpserver.cisco.com/downloads/n7000-s2-kickstart.8.0.1.bin n7000-s2-kickstart.8.0.1.bin  
switch# copy scp://user@scpserver.cisco.com/downloads/n7000-s2-dk9.8.0.1.bin n7000-s2-dk9.8.0.1.bin
Step 9

Read the release notes for the related image file. See the Cisco Nexus 7000 Series NX-OS Release Notes.

Step 10

Use the install all command to update the boot variables and module images on your device.


switch# install all kickstart n7000-s2-kickstart.8.0.1.bin system n7000-s2-dk9.8.0.1.bin

Note 

Beginning with Cisco NX-OS Release 5.2, you can save time by upgrading up to three line cards concurrently. To do so, add the parallel option at the end of the install all command (for example, install all kickstart bootflash:n7000-s1-kickstart.5.2.1.bin system bootflash:n7000-s1-dk9.5.2.1.bin parallel). The parallel option is available only when you are upgrading from Cisco NX-OS Release 5.2 to a later release.

Step 11

After the device completes the reload operation, log in and verify that the device is running the required software version.

switch# reload cmp module 6

Step 14

(Optional) Install licenses to ensure that the required features are available on the device. See the Cisco NX-OS Licensing Guide.


Performing a Traditional Upgrade or Downgrade (Chassis Reload)

This procedure is recommended for these specific scenarios:
  • In lab environments where continuous uptime is not a requirement

  • In production environments in the unlikely event that an upgrade needs to be downgraded in a timely manner

  • In situations where ISSU or ISSD is not supported for the respective images

Before you begin

Save and back up all configurations before reloading the system to load the new software.

Power down unsupported line cards.

Procedure


Step 1

Configure the boot variable for the Cisco NX-OS software kickstart image.


switch(config)# boot kickstart bootflash:n7000-s2-kickstart.8.0.1.bin
Step 2

Configure the boot variable for the Cisco NX-OS software system image.


switch(config)# boot system bootflash:n7000-s2-dk9.8.0.1.bin
Step 3

Save the running configuration to the startup configuration.


switch# copy running-config startup-config vdc-all
Step 4

Verify that the "Current Boot Variables" and the "Boot Variables on the next reload" match the expected image.


Current Boot Variables:

sup-2
kickstart variable = bootflash:/n7000-s2-kickstart.8.0.1.bin system variable = bootflash:/n7000-s2-dk9.8.0.1.bin
No module boot variable set
Boot Variables on next reload: sup-1
kickstart variable = bootflash:/n7000-s2-kickstart.8.0.1.bin system variable = bootflash:/n7000-s2-dk9.8.0.1.bin
sup-2
kickstart variable = bootflash:/n7000-s2-kickstart.8.0.1.bin system variable = bootflash:/n7000-s2-dk9.8.0.1.bin
No module boot variable set
Step 5

Verify that the image location and the image name match the above boot statements. In redundant supervisor chassis, the images auto-synchronize from to standby once the boot statements are set.

switch# show boot auto-copy list
switch# dir bootflash://sup-active/ 
  161980383    May 15 17:52:03 2016  n7000-s2-dk9.8.0.1.bin
   29471232    May 15 18:01:38 2016  n7000-s2-kickstart.8.0.1.bin

switch# dir bootflash://sup-standby/ 
  161980383    May 15 18:04:55 2016  n7000-s2-dk9.8.0.1.bin
   29471232    May 15 18:06:18 2016  n7000-s2-kickstart.8.0.1.bin
Step 6

After you verify the image location and statements, reload the Cisco NX-OS device.

switch# reload

Example Outputs from Cisco NX-OS Software Upgrades

This section includes example outputs from Cisco NX-OS software upgrades.

  • The output of the install all command depends on the software image, especially the upgrade required (Upg-Required) field information in the upgrade table.

  • Any time you perform a disruptive ISSU, the supervisor modules will be reloaded.

Example Nondisruptive Upgrade of a Device with Dual Supervisors

The following example has the console session output that shows a nondisruptive execution of the install all command on a device with dual supervisor modules:
