Foundry Switch and Router Installation and Configuration Guide
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:
BigIron(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.
Using the Executable Boot Command
You can use boot commands to immediately initiate software boots from a software image stored in primary or
secondary flash on a Foundry Layer 3 Switch or from a BootP or TFTP server. You can test new versions of code
on a Layer 3 Switch or choose the preferred boot source from the console boot prompt without requiring a system
reset.
NOTE: The boot flash must have release 2.0 or later boot code installed for this feature to be supported. To
determine the system's boot code versions, enter the show flash command.
SPECIAL NOTE FOR BOOT UPGRADE: Release 2.0 or later switching or router code is required to upgrade the
boot code. To upgrade the boot flash code, you can use the following unadvertised CLI command:
BigIron# copy tftp flash <tftp-ip-addr> <filename> boot
This command is at the privileged EXEC level of the CLI.
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 Layer 3 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
Foundry Switch and Router Command Line Interface Reference.
USING THE WEB MANAGEMENT INTERFACE
To initiate an immediate boot from the primary boot source:
1. Click on the plus sign next to Command in the tree view to expand the list of command options.
2. Select the Reload option.
3. Select Yes when the Web management interface asks you whether you really want to reload.
To initiate an immediate boot from a boot source other than the primary boot source:
1. Click on the plus sign next to Configure in the tree view to expand the list of configuration options.
2. Click on the plus sign next to System in the tree view to expand the list of system configuration options.
3. Select the Boot Sequence link to display the following panel.
