Note

We recommend that you have the image file for at least one previous release of the NX-OS software on the device to use if the new image file does not load successfully.

switch# copy scp://user@scpserver.cisco.com//download/nxos64.10.2.1.F.bin bootflash:nxos64.10.2.1.F.bin

Note

The compaction feature is deprecated from NX-OS Release 10.5(2)F

For software images requiring compaction, you must use SCP, HTTP, or HTTPS as the source and bootflash or USB as the destination. This example uses SCP and bootflash:

switch# copy scp://user@scpserver.cisco.com//download/nxos64.10.2.1.F.bin 
bootflash:nxos64.10.2.1.F.bin compact vrf management use-kstack

nxos64.10.2.1.F.bin 100% 1887MB 6.6MB/s 04:47
Copy complete, now saving to disk (please wait)...
Copy complete.

The compact keyword compacts the NX-OS image before copying the file to the supervisor module.

Note

Software image compaction is only supported on SCP, HTTP, or HTTPS. If you attempt compaction with any other protocol, the system returns the following error:

Compact option is allowed only with source as scp/http/https and destination
as bootflash or usb

Note

Compacted images are not supported with LXC boot mode.

Note

Software image compaction is only supported on Nexus 9300-series platform switches.

Note

From NX-OS Release 10.5(3)F, EPLD upgrade can be performed with either the no-reload or the non-disruptive option.

The available options are:

• no-reload—Exits the software upgrade process before the device reloads.

  Note

  When you use install all with no-reload option, no additional configuration changes can be made before you reload the device. Saving configuration in this state can result in incorrect startup configuration once you reload the device with the new version of NX-OS (along with EPLD from 10.5(3)F). From Release 10.5(3)F onwards, though the EPLD and BIOS are programmed but not upgraded, a switch reload is required for them to take effect.

• non-disruptive—Performs an in-service software upgrade (ISSU) to prevent the disruption of data traffic. (By default, the software upgrade process is disruptive.) From Release 10.5(3)F onwards, though the EPLD and BIOS are programmed but not upgraded, a switch reload is required for them to take effect.

• non-interruptive—Upgrades the software without any prompts. This option skips all error and sanity checks.

• serial—Upgrades the I/O modules in Nexus 9500 Series switches one at a time. (By default, the I/O modules are upgraded in parallel, which reduces the overall upgrade time. Specifically, the I/O modules are upgraded in parallel in this order: the first half of the line cards and fabric modules, the second half of the line cards and fabric modules, the first system controller, the second system controller.)

• skip-epld—Installs only the nxos image, and not the epld image. This option is available from 10.5(3)F.

• skip-bios-upgrade—Installs only the nxos image, and skips the BIOS upgrade. This option is available from 10.5(3)F.

• skip-kernel-upgrade—Installs only the nxos image, and skips the kernel upgrade. This option is available from 10.5(3)F.

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.

• Starting from 10.5(3)F, during the image upgrade, you can also apply SMUs so the SMU is installed with the new image using the install all nxos <nxos image> package <smu package> non-disruptive non-interruptive command.
