When the device serves as the TFTP client, you must perform the following configuration:

Remarks
Device (TFTP client)
• Configure the IP address and routing function, and ensure that the
route between the device and the TFTP server is available.
• Use tftp to establish a connection to the remote TFTP server to
upload/download files to/from the TFTP server
—
PC (TFTP server)
Enable TFTP server on the PC, and configure the TFTP working
directory.

Configuring the TFTP client
When a device acts as a TFTP client, upload a file on the device to a TFTP server and download a file from
the TFTP server to the local device. Use either of the following methods to download a file:
• Normal download—The device writes the obtained file to the storage medium directly. In this way, if you
download a remote file using a filename destination-filename that exists in the directory, the device
deletes the original file and then saves the new one. If file download fails due to network disconnection
or other reasons, the original system file will never recover because it has been deleted.
• Secure download—The device saves the obtained file to its memory and does not write it to the storage
medium until the whole file is obtained. If you download a remote file using a filename
destination-filename that exists in the directory, the original file is not overwritten. If file download fails
due to network disconnection or other reasons, the original file still exists. This mode is more secure but
consumes more memory.
HP recommends using the secure mode or, if you use the normal mode, specify a filename not existing in the
current directory as the target filename when downloading the boot file or the startup configuration file.
Before using tftp to establish a TFTP connection, perform source address binding. Source address binding
means configuring an IP address on a stable interface such as a loopback interface, and then using this IP
address as the source IP address of a TFTP connection. The source address binding function simplifies the
configuration of ACL rules and security policies. You just need to specify the source or destination address
argument in an ACL rule as this address to filter inbound and outbound packets on the device, ignoring the
difference between interface IP addresses as well as the effect of interface statuses. Configure the source
address by configuring the source interface or source IP address. The primary IP address configured on the
source interface is the source address of the transmitted packets.
