This document describes how to upgrade or downgrade the Cisco NX-OS software.
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. |
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
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.
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, Release 4.2.
Before attempting to migrate 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).
Hardware
Avoid power interruption during any install procedure, which can corrupt the software image.
Connectivity to remote servers
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:
Terminology
Term |
Definition |
|
---|---|---|
bootable |
The modules 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 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.
Do not issue 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 may 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 install all command supports in-service software upgrade (ISSU) on devices that have dual supervisor modules and performs the following actions:
Determines whether the upgrade will be disruptive and asks if you wish to continue.
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.
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. Once the effects of the command are presented, 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:
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 an MDS 9500 Series image is used inadvertently to upgrade an MDS 9200 Series switch.
The Ctrl-c escape sequence gracefully ends the install all command. 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 issuing 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), then 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 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 the install all command is issued 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).
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.
The following summary procedure describes how to upgrade a device that has dual supervisor modules to the latest Cisco NX-OS software.

Step 15 | (Optional) Install licenses to ensure that the required features are available on the device. See the Cisco Nexus 7000 Series NX-OS Licensing Guide, Release 4.2. |
Only users with the network-admin role can downgrade the Cisco NX-OS software image and only from the default virtual device context (VDC).
![]() Note |
If you downgrade from Release 4.2(1) or later release to Release 4.1(5) or earlier release, you may encounter a problem with the dynamic TCAM allocation feature. If the Cisco NX-OS software has reallocated the TCAM, the nondisruptive downgrade fails with the following error message: TCAM allocation has changed You must return the TCAM to the defaualt allocation before you can nondisruptively downgrade your device. For information on how to return the TCAM to the default allocation, see the Cisco Nexus 7000 Series NX-OS Unicast Routing Configuration Guide, Release 4.2. |
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:. Example: switch# dir bootflash: 49152 Apr 16 14:43:39 2008 lost+found/ 80850712 Apr 04 15:57:44 2008 n7000-s1-dk9.4.2.1.bin 22593024 Apr 04 15:52:56 2008 n7000-s1-kickstart.4.2.1.bin 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.
Example: 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. Example: 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. Example: switch# copy running-config startup-config vdc-all |
||
Step 7 | Upgrade the Cisco NX-OS software. |
This section includes examples outputs from Cisco NX-OS software upgrades.
![]() Note |
The output of the install all command depends on the software image, especially the upgrade required (Upg-Required) field information in the upgrade table. |
The following console session output shows a nondisruptive execution of the install all command on a device with dual supervisor modules:
