Optional show boot mode. Reloads the device. When prompted, press Y to confirm the reboot. Make sure to choose the non-disruptive option if you want to perform an enhanced or regular ISSU. Read the release notes for the software image file for any exceptions to this upgrade procedure. We recommend that you have the image file for at least one previous release of the Cisco NX-OS software on the device to use if the new image file does not load successfully.

If you need more space on the active supervisor module, delete unnecessary files to make space available. If you need more space on the standby supervisor module, delete any unnecessary files to make space available. Log in to Cisco. Copy the software image to the active supervisor module using a transfer protocol. The following example uses SCP and bootflash:.

The compact keyword compacts the NX-OS image before copying the file to the supervisor module. If you attempt compaction with any other protocol, the system returns the following error:. Check the impact of upgrading the software before actually performing the upgrade. By default, the software upgrade process is disruptive. You must configure the non-disruptive option to perform an ISSU. Upgrade the Cisco NX-OS software using the install all nxos bootflash: filename [ no-reload non-disruptive non-interruptive serial ] command.

This option skips all error and sanity checks. Optional Log in and verify that the device is running the required software version. Optional If necessary, install any licenses to ensure that the required features are available on the device. The following list summarizes the upgrade process on a switch in a vPC topology that holds either the Primary or Operational Primary vPC roles.

Steps that differ from a switch upgrade in a non-vPC topology are in bold. In vPC topologies, the two peer switches must be upgraded individually. An upgrade on one peer switch does not automatically update the vPC peer switch.

The install all command issued on the vPC primary switch triggers the installation upgrade. The configuration is locked on both vPC peer switches. The vPC primary switch is running the upgraded version, and the vPC secondary switch is running the original software version.

The following list summarizes the upgrade process on a switch in a vPC topology that holds either the Secondary or Operational Secondary vPC roles. The install all command issued on the vPC secondary switch triggers the installation upgrade. The configuration is unlocked on the primary and secondary switches. Read the release notes for the software image file for any exceptions to this downgrade procedure. Verify that the image file for the downgrade is present on the active supervisor module bootflash:.

If the software image file is not present, log in to Cisco. If you need more space on the active or standby supervisor module bootflash:, use the delete command to remove unnecessary files. During the life of a Cisco Nexus switch, many upgrade procedures can be performed. Upgrades can occur for maintenance purposes or to update the operating system to obtain new features.

Over time, switches may be updated on numerous occasions. Viewing the types of upgrades and when they occurred can help in troubleshooting issues or simply understanding the history of the switch. The stored upgrade history types are:. The output displays any upgrade activity that previously occurred on the switch and defines the start and end times for each event. The following is an example output of the show upgrade history command:.
