What occurs when the following command is run on a Cisco Nexus 9000 Series Switch?

The install all epld command initiates installation of the specified Electronic Programmable Logic Device image on applicable components of the Nexus switch. EPLD updates reprogram hardware logic and commonly require affected modules or the switch to reload, making the operation disruptive. The command shown does not contain a verification, compatibility-check, or simulation keyword; consequently, it performs the upgrade rather than merely reporting its expected effect. A compatibility or impact assessment would require the appropriate pre-upgrade verification mechanism. A simulated upgrade would likewise require a specific simulation or dry-run option that is absent from the displayed command. Administrators should confirm platform compatibility, save the configuration, schedule a maintenance window, and account for traffic interruption before executing the actual EPLD installation. Therefore, the direct result of the command is a disruptive EPLD upgrade.
