Rebooting
TurboIron(config)#flash 2047
set flash copy block size to 2048
Syntax: [no] flash <num>
The software rounds up the <num> value you enter to the next valid power of two, and displays the
resulting value. In this example, the software rounds the value up to 2048.
NOTE
If the value you enter is one of the valid powers of two for this parameter, the software still rounds
the value up to the next valid power of two. Thus, if you enter 2048, the software rounds the value
up to 4096.
Rebooting
You can use boot commands to immediately initiate software boots from a software image stored
in primary or secondary flash on a device or from a BootP or TFTP server. You can test new
versions of code on a device or choose the preferred boot source from the console boot prompt
without requiring a system reset.
NOTE
It is very important that you verify a successful TFTP transfer of the boot code before you reset the
system. If the boot code is not transferred successfully but you try to reset the system, the system
will not have the boot code with which to successfully boot.
By default, the device first attempts to boot from the image stored in its primary flash, then its
secondary flash, and then from a TFTP server. You can modify this booting sequence at the global
CONFIG level of the CLI using the boot system… command.
To initiate an immediate boot from the CLI, enter one of the boot system… commands.
NOTE
If you are booting the device from a TFTP server through a fiber connection, use the following
command: boot system tftp <ip-address> <filename> fiber-port.
Displaying the boot preference
Use the show boot-preference command to display the boot sequence in the startup config and
running config files. The boot sequence displayed is also identified as either user-configured or the
default.
The following example shows the default boot sequence preference.
TurboIron#show boot-preference
Boot system preference (Configured):
Use Default
Boot system preference(Default):
Boot system flash primary
Boot system flash secondary
The following example shows a user-configured boot sequence preference.
