Changing the Block Size for TFTP File Transfers

When you use TFTP to copy a file to or from a Foundry 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, enter a command such as the following at the global CONFIG
level of the CLI:
FESX424 Router(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 Foundry device or from a BootP or TFTP server. You can test new versions of code on a
Foundry 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 Foundry 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 as described in the
Foundry Switch and Router Command Line Interface Reference.

Loading and Saving Configuration Files

For easy configuration management, all Foundry devices support both the download and upload of configuration
files between the devices and a TFTP server on the network.
You can upload either the startup configuration file or the running configuration file to the TFTP server for backup
and use in booting the system.
• Startup configuration file – This file contains the configuration information that is currently saved in flash.
