firmware download usb
Specifies USB as the protocol used to perform a firmware download.
Synopsis firmware download usb [coldboot] [noactivate] [nocommit] [noreboot] [manual] directory directory
Operands coldboot Performs a non-ISSU firmware download. When firmware is downloaded
onto a chassis system, it is sometimes necessary to specify the coldboot
option. This option must be specified on the active MM only. When
specified, the coldboot option downloads firmware onto both the active and
standby MMs at the same time. After the firmware completes downloading
on both MMs, they are rebooted at the same time. This ensures that both
MMs reboot with the same firmware, and prevents any firmware
compatibility issues that may exist between the old and the new firmware.
Caution: Do not use this option unless instructed to do so by Brocade
Technical Support.
directory directory Specifies a fully qualified path to the directory where the firmware is
located.
manual Updates a single management module in a chassis with two management
modules. You must log in to the management module through its dedicated
management IP address. This parameter is ignored when issued on a
compact switch or in a chassis with only one management module.
noactivate Performs a firmware download without activation on the local switch.
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 switch manually. If auto-commit mode was disabled, you must
perform a manual firmware commit operation after the switch comes back
up.
Defaults None
Command Modes Privileged EXEC mode
Description 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.
The device components supported by this command have two partitions of nonvolatile storage
(primary and secondary) to store two firmware images. This command always downloads the new
image to the secondary partition and then swaps partitions, so the secondary partition becomes
the primary partition.
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.
Usage Guidelines This command supports firmware upgrades on the local switch only.
