firmware download usb

Specifies USB as the protocol used to perform a firmware download.

Syntax

firmware download usb [ coldboot ] [ noactivate ] [ nocommit ] [ noreboot ] [ manual ] directory directory

Command Default

By default, the firmware download process reboots the system and activates the new image. Finally, the process performs a firmware commit operation to copy the new image to the other partition.

Parameters

coldboot: Downloads the firmware to the system and reboots both the active and standby MMs. Caution: Do not use this option unless instructed to do so by Extreme Technical Support.
directory directory: Specifies a fully qualified path to the directory where the firmware is located.
manual: Currently, this keyword has no effect.
noactivate: Performs a firmware download without activation on the local device.
nocommit: Disables auto-commit mode. When auto-commit mode is disabled, firmware is downloaded only to the primary partition. You must execute the firmware commit command manually to propagate the new image to the secondary partition.
noreboot: Disables auto-reboot mode. When auto-reboot mode is disabled, you must reboot the device manually. If auto-commit mode was disabled, you must perform a manual firmware commit operation after the device comes back up.

Modes

Privileged EXEC mode

Usage Guidelines

Use this command to download firmware from an external host or from an attached USB device. You can run this command interactively or provide the parameters on the command line.

Unless you specify noactivate, the upgrade or downgrade involves system reboots that disrupt traffic.

In addition, default-config causes the loss of configuration because it resets the configuration back to the default settings during the firmware upgrade process.

If the firmware download command is interrupted because of an unexpected reboot, such as a result of a software error or power failure, the command automatically recovers the corrupted secondary partition. Wait for the recovery to complete before beginning another firmware download.

This command does not support pagination.

If the firmware download is interrupted because of an unexpected reboot as a result of a software error or power failure, the command automatically recovers the corrupted secondary partition. Wait for the recovery to complete before starting another firmware download.
