NX-OS image boot modes

Updated: February 5, 2026

Overview

This section defines the base and full boot modes for NX-OS and provides the commands to switch between them. It explains how to reset the switch to install either a minimal set of core features or the complete software image.

You can boot the NX-OS image in base or full mode. The full boot mode installs the complete NX-OS software which is similar to the software of the previous releases. This is the default boot mode. The base boot mode has no optional RPMs installed.

To use the command line option, perform one of these steps depending on the mode.

  • Use the install reset nxos base option to install the NX-OS image in the base boot mode using the VSH prompt. After reload, the switch is in the base mode with no optional packages installed.

  • Use the install reset nxos full option to install the NX-OS image in the full boot mode using the VSH prompt. After reload, the switch is in the full mode with the optional packages automatically installed.
