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. 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:. 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.
This table summarizes the terms used in the install all command output for checking compatibility. The module's ability to boot or not boot based on image compatibility. The type of software upgrade mechanism—disruptive or nondisruptive. Resets the module immediately after a switchover. Updates the software for BIOS, loader, or bootrom. 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. Do not enter another command while running the installation.
Do the installation on the active supervisor module, not the standby supervisor module. The install all command output identifies these commands.
You can choose to proceed with the upgrade or end at this point. You can have only one instance of the install all command running. See the release notes for information on the new features introduced in each release. You will have to perform a cold boot of the switch. Operating VPC peers with dissimilar versions, after the upgrade or downgrade process is complete, is not supported. The install all command supports in-service software upgrades ISSUs on devices that have dual supervisor modules and performs the following actions:.
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.
You can continue or cancel when you see this question the default is no :. 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 device image is used inadvertently to upgrade a Nexus 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.
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. 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 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 images are incompatible after an upgrade. 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. The following summary procedure describes how to upgrade a device that has dual supervisor modules to the latest Cisco NX-OS software. Log in to Cisco. Download the Cisco NX-OS kickstart and system images from the server to your device using the copy command. Save the device configuration using the copy running-config startup-config vdc-all command. Enter the install all command at the active supervisor command prompt to upgrade the Cisco NX-OS software on your device.
This section describes the detailed procedure to upgrade to the latest Cisco NX-OS software on a device with dual supervisor modules. Log in to the device on the console port connection on both of the active and standby supervisor modules. To log in to Cisco. Enter your Cisco username and password. Unregistered Cisco. Navigate to the download site for your device.
Select and download the kickstart and system software files to a server. Ensure that the required space is available for the image file s to be copied. If you need more space on the active supervisor module, delete unnecessary files to make space available. Verify that there is space available on the standby supervisor module. If you need more space on the standby supervisor module, delete any unnecessary files to make space available.
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:. Read the release notes for the related image file. Save the running configuration to the startup configuration. Perform the upgrade using the install all command at the command prompt on the active supervisor module. 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.
After the installation operation completes, log in and verify that the device is running the required software version using the show version command. CMP is a Supervisor 1 only feature. Type the show install all status command. Optional Install licenses if necessary to ensure that the required features are available on the device.
The following summary procedure describes how to upgrade a device that has a single supervisor module to the latest Cisco NX-OS software. This section describes the detailed procedure to upgrade to the latest Cisco NX-OS software on a device with a single supervisor.
Log in to the device on the console port connection. Ensure that the required space is available in the bootflash: directory for the image file s to be copied.
If you need more space on the supervisor module bootflash, delete unnecessary files to make space available. Copy the NX-OS kickstart and system images to the active supervisor module bootflash using a transfer protocol.
Use the install all command to update the boot variables and module images on your device. To do so, add the parallel option at the end of the install all command for example, install all kickstart bootflash:ns1-kickstart. After the device completes the reload operation, log in and verify that the device is running the required software version. Optional Install licenses to ensure that the required features are available on the device.
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. Save and back up all configurations before reloading the system to load the new software.
Verify that the "Current Boot Variables" and the "Boot Variables on the next reload" match the expected image. 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. 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 example has the console session output that shows a nondisruptive execution of the install all command on a device with dual supervisor modules:. As displayed, once the active supervisor module reloads, the output for the standby supervisor module is displayed.
A supervisor module switchover has occurred, and the active supervisor module is now the standby supervisor module. The following console session example output shows a disruptive execution of the install all command on a device with dual supervisor modules:. A supervisor module switchover has occurred and the active supervisor module is now the standby supervisor module.
The following example console session output from the standby supervisor module shows that the standby supervisor module switches over to become the active supervisor module:. The following console session example output shows a disruptive execution of the install all command on a device with a single supervisor module:.
