Rebooting; Changing The Block Size For Tftp File Transfers - HP 9304m Installation And Getting Started Manual

Changing the Block Size for TFTP File Transfers

When you use TFTP to copy a file to or from an HP device, the device transfers the data in blocks of 8192 bytes by
default. You can change the block size to one of the following if needed:
• 4096
• 2048
• 1024
• 512
• 256
• 128
• 64
• 32
• 16
To change the block size for TFTP file transfers to and from the HP device, use the following CLI method.
USING THE CLI
To change the block size for TFTP file transfers, enter a command such as the following at the global CONFIG
level of the CLI:
HP9300(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.
USING THE WEB MANAGEMENT INTERFACE
You cannot configure this option using the Web management interface.

Rebooting

You can use boot commands to immediately initiate software boots from a software image stored in primary or
secondary flash on an HP Routing Switch or from a BootP or TFTP server. You can test new versions of code on
a Routing Switch 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 Routing Switch 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.
USING THE CLI
To initiate an immediate boot from the CLI, enter one of the boot system... commands as described in the
Command Line Interface Reference .
