Changing the block size for TFTP file transfers
3
This command disables password checking for SNMP set requests. If a third-party SNMP
management application does not add a password to the password field when it sends SNMP
set requests to a device, by default the device rejects the request.
Changing the block size for TFTP file transfers
When you use TFTP to copy a file to or from a 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.
PowerConnect(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.
