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
Figure 1. ISSU Process. This figure shows the ISSU process.

Figure 2. Example of an ISSU Supervisor Module Switchover. This figure provides an example of the supervisor module status before and after an ISSU switchover.

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

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.

[####################] 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 is supported if the user types the parallel keyword in the command.

For releases prior to Cisco NX-OS Release 6.1(1), only a serial upgrade of Fabric Extenders 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

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 200 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.
    • The default Control Plane Policing (CoPP) policy does not change when you upgrade the Cisco NX-OS software.
    • When upgrading from Cisco NX-OS Release 5.0 to a later 5.x release, you must disable Bidirectional Forwarding Detection (BFD) before the upgrade and reenable it after the upgrade.
    • CoPP MAC policies are supported beginning with Cisco NX-OS Release 5.1, and default policies are installed upon execution of the initial setup script. However, if you use ISSU to upgrade to Cisco NX-OS Release 5.1, the default CoPP policies for the following features must be manually configured: FabricPath, OTV, L2PT, LLDP, DHCP, and DOT1X. For more information on the default CoPP policies, see the Cisco Nexus 7000 Series NX-OS Security Configuration Guide, Release 5.x.
    • When you upgrade to Cisco NX-OS Release 5.2, the policy attached to the control plane is treated as a user-configured policy. Check the CoPP profile using the show copp profile command and make any required changes.
    • The upgrade to Cisco NX-OS Release 5.2 in an OTV network is disruptive. You must upgrade all edge devices in the site and configure the site identifier on all edge devices in the site before traffic is restored. You can prepare OTV for ISSU to Cisco NX-OS Release 5.2 in a dual-homed site to minimize this disruption. See the Cisco Nexus 7000 Series NX-OS OTV Configuration Guide for information on how to prepare OTV for ISSU to Cisco NX-OS Release 5.2 in a dual-homed site. An edge device with an older Cisco NX-OS release in the same site can cause traffic loops. You should upgrade all edge devices in the site during the same upgrade window. You do not need to upgrade edge devices in other sites as OTV interoperates between sites with different Cisco NX-OS versions.
  • Terminology
    This table summarizes the terms used in the install all command output for checking compatibility.

    Table 1  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

Before attempting to use the in-service software downgrade (ISSD) to downgrade to any software image version, follow these 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.
  • When downgrading to Cisco NX-OS Release 5.0 from a later 5.x release, you must disable Bidirectional Forwarding Detection (BFD) before the downgrade and reenable it after the downgrade.
  • Downgrading from Cisco NX-OS Release 5.x to earlier releases is not allowed if you configure fewer than five fabric cards in a Cisco NX-OS device using the hardware fabrics max command. For information on configuring the number of fabric cards supported on your device, see the Cisco Nexus 7000 Series Hardware Installation and Reference Guide.
  • If you create a dedicated Fibre Channel over Ethernet (FCoE) VDC in Cisco NX-OS Release 5.2 or later releases, you must delete the FCoE VDC before downgrading to an earlier software release.
  • If you enable the AES password encryption feature and a master encryption key in Cisco NX-OS Release 5.2 or later releases, you must decrypt all type-6 passwords, disable the AES password encryption feature, and delete the master key.
  • If you use ISSD to downgrade from Cisco NX-OS Release 5.2 to an earlier software release, CoPP reports the incompatible configuration and instructs you to copy the CoPP profile. In the earlier software release, all configurations are restored in user-configuration mode.
  • If you downgrade from Cisco NX-OS Release 5.2 without using ISSD, the CoPP configuration is lost, and a CoPP policy is no longer attached to the control plane.
  • Before you downgrade from Cisco NX-OS Release 5.2 to Cisco NX-OS Release 5.0, remove all system QoS and qos policies configured on F1 Series modules. Use the clear qos policies command to remove the F1 Series module related defaults.
  • Before you downgrade from Cisco NX-OS Release 5.2 to an earlier Cisco NX-OS release, clear the QoS MIB and MPLS QoS defaults using the clear qos mpls-snmp command. Otherwise, the downgrade might fail.
  • If you downgrade the device from Cisco NX-OS Release 5.2(x) or 5.1(x) to Cisco NX-OS Release 5.0(x) or 4.2(x), AAA configuration commands might fail. The workaround is to write-erase the startup configuration and reboot the device.

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.

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 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.

      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 active supervisor module, delete unnecessary files to make space available.
      switch# delete bootflash:n7000-s1-kickstart.4.2.1.bin
      switch# delete bootflash:n7000-s1-dk9.4.2.1.bin
      
      
      Step 8   Verify that there is space available on the standby supervisor module.
      switch# dir bootflash://sup-standby/

        800604904 bytes free
        904097792 bytes total
      
      
      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-s1-kickstart.4.2.1.bin
      switch# delete bootflash://sup-standby/n7000-s1-dk9.4.2.1.bin
      
      
      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-s1-kickstart.4.2.1.bin bootflash:n7000-s1-kickstart.4.2.1.bin 
      switch# copy scp://user@scpserver.cisco.com//downloads/n7000-s1-dk9.4.2.1.bin bootflash:n7000-s1-dk9.4.2.1.bin
      
      
      Step 11   Read the release notes for the related image file. See the Cisco Nexus 7000 Series NX-OS Release Notes, Release 5.x.
      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 bootflash:n7000-s1-kickstart.4.2.1.bin system bootflash:n7000-s1-dk9.4.2.1.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.

       

      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.

          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.4.2.1.bin
          switch# delete bootflash:n7000-s1-dk9.4.2.1.bin
          
          
          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-s1-kickstart.4.2.1.bin bootflash:n7000-s1-kickstart.4.2.1.bin 
          switch# copy scp://user@scpserver.cisco.com//downloads/n7000-s1-dk9.4.2.1.bin bootflash:n7000-s1-dk9.4.2.1.bin
          
          
          Step 9   Read the release notes for the related image file. See the Cisco Nexus 7000 Series NX-OS Release Notes, Release 5.x.
          Step 10   Use the install all command to update the boot variables and module images on your device.
          switch# install all kickstart bootflash:n7000-s1-kickstart.4.2.1.bin system bootflash:n7000-s1-dk9.4.2.1.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.

          Downgrading from a Higher Release

          Only users with the network-admin role can use ISSD to downgrade the Cisco NX-OS software image and only from the default virtual device context (VDC).

          Prior to downgrading your software, use the show incompatibility-all system image-filename command. The resulting output displays incompatibilities and remedies.

          Procedure
            Step 1   Log in to the device on the console port connection.
            Step 2   Verify that the system image files for the downgrade are present on the active supervisor module bootflash:
            switch# dir bootflash: 
                  49152 Apr 16 14:43:39 2008 lost+found/

            Usage for bootflash://sup-local
              103492888 bytes used
              800604904 bytes free
              904097792 bytes total
            
            Step 3   If the software image files are not present, 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. You can obtain the software image files from the Cisco.com software download center at the following URL: http:/​/​www.cisco.com/​public/​sw-center/​index.shtml.
            Note   

            If you need more space on the active or standby supervisor module bootflash:, use the delete command to remove unnecessary files.

            switch# copy scp://user@scpserver.cisco.com//downloads/n7000-s1-kickstart.4.2.1.bin bootflash:n7000-s1-kickstart.4.0.1a.bin 
            switch# copy scp://user@scpserver.cisco.com//downloads/n7000-s1-dk9.4.2.1.bin bootflash:n7000-s1-dk9.4.0.1a.bin
            
            Step 4   Determine if you need to disable any features not supported by the older release using the show incompatibility system image-filename command.
            switch# show incompatibility system bootflash:n7000-s1-dk9.4.2.1.bin 
            The following configurations on active are incompatible with  the system image 
            1) Service : eth_port_channel , Capability : CAP_FEATURE_AUTO_CREATED_PORT_CHANNEL 
            Description : active mode port channels, auto create enabled ports or auto created 
            port-channels are present 
            Capability requirement : STRICT 
            Disable command : 1.Convert Active mode port channels to On mode port channels 
            (no channel mode active). 
            2.Disable autocreate on interfaces (no channel-group auto). 
            3.Convert autocreated port channels to be persistent (port-channel 1 persistent).
            
            Step 5   Disable any features that are incompatible with the downgrade system image.
            Step 6   Save the running configuration to the startup configuration.
            switch# copy running-config startup-config vdc-all
            
            Step 7   Downgrade the Cisco NX-OS software.
            switch# install all kickstart n7000-s1-kickstart.4.2.1.bin system n7000-s1-dk9.4.2.1.bin
            
            Note   

            The output displayed is similar to the output you see when you install software using the install all command.


            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# boot kickstart bootflash:n7000-s1-kickstart.6.0.1.bin 
              
              
              Step 2   Configure the boot variable for the Cisco NX-OS software system image.
              switch# boot system bootflash:n7000-s1-dk9.6.0.1.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 next reload" match the expected image.
              switch# show boot
              Current Boot Variables:
              
              sup-1
              kickstart variable = bootflash:/n7000-s1-kickstart.6.0.1.bin
              system variable = bootflash:/n7000-s1-dk9.6.0.1.bin
              sup-2
              kickstart variable = bootflash:/n7000-s1-kickstart.6.0.1.bin
              system variable = bootflash:/n7000-s1-dk9.6.0.1.bin
              No module boot variable set
              
              Boot Variables on next reload:
              
              sup-1
              kickstart variable = bootflash:/n7000-s1-kickstart.6.0.1.bin
              system variable = bootflash:/n7000-s1-dk9.6.0.1.bin
              sup-2
              kickstart variable = bootflash:/n7000-s1-kickstart.6.0.1.bin
              system variable = bootflash:/n7000-s1-dk9.6.0.1.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 active to standby once the boot statements are set.
              switch# show boot auto-copy list
              switch# dir bootflash://sup-active/ 
                161980383    Aug 15 17:52:03 2011  n7000-s1-dk9.6.0.1.bin
                 29471232    Aug 15 18:01:38 2011  n7000-s1-kickstart.6.0.1.bin
              
              
              switch# dir bootflash://sup-standby/ 
                161980383    Aug 15 18:04:55 2011  n7000-s1-dk9.6.0.1.bin
                 29471232    Aug 15 18:06:18 2011  n7000-s1-kickstart.6.0.1.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 console session output shows a nondisruptive execution of the install all command on a device with dual supervisor modules:

              switch# install all kickstart n7000-s1-kickstart.6.0.1.bin system n7000-s1-dk9.6.0.1.bin
