Management
TFTP Tab Field Descriptions
You must have a TFTP server running on any host that you are uploading or downloading files
to/from.
Note:
TFTP file transfers send via UDP packets. When the packet delivery is interrupted for any
reason and a timeout occurs, that packet is resent if the retry count allows it. Therefore, if a
very large file is being transferred and is interrupted, the entire file is not resent, just the part
of the file that was not received.
Configure the following parameters:
Retry
Timeout
Console Port Tab Field Descriptions
This tab is found on rack mount models and is used to configure the Admin/Console port.
Configure the following parameters:
Baud Rate
x
Flow Control
The number of times the IOLAN will retry to transmit a TPFT packet to/from a
host when no response is received. A value of 0 (zero) means that the IOLAN
will not attempt a retry should TFTP fail.
Range: 0-5
Default: 5
The time, in seconds, that the IOLAN will wait for a successful transmit or
receipt of TFTP packets before retrying a TFTP transfer.
Range: 3-10
Default: 3 seconds
Specifies the baud rate of the line connected to the dedicated console port.
Data Options: 9600, 19200, 38400, 57600, 115200
Default: 9600
For IOLAN models that have a dedicated console port, defines how the data
flow is handled.
Data Options:
z Soft—Data flow control is handled by the software.
z Hard—Data flow control is handled by the hardware.
z None—There is no data flow control.
Default: None
