Changing the block size for TFTP file transfers

1. Configure a read-write community string on the Dell PowerConnect device, if one is not already
configured. To configure a read-write community string, enter the following command from the
global CONFIG level of the CLI.
snmp-server community <string> ro | rw
where <string> is the community string and can be up to 32 characters long.
2. On the Dell PowerConnect device, enter the following command from the global CONFIG level
of the CLI.
no snmp-server pw-check
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 Dell PowerConnect device, by default the Dell PowerConnect device rejects
the request.
Changing the block size for TFTP file transfers
When you use TFTP to copy a file to or from a Dell PowerConnect 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.
