TFTP Download Error Codes
During a TFTP download, if tracing is on, non-fatal errors appear in the midst of dots that display as
the software downloads. The error code appears inside angle brackets.
For example, random bad blocks would appear as follows:
....<11>..<11>.<11>......<11>...
Also, tracing will show “A” and “T” for ARP and timeouts, respectively. Receipt of non-IP packets
causes the protocol number to display inside parentheses.
Table2-3 lists the TFTP error codes.
Note Error codes 9 and 10 cause the download to stop.

Error
Code Description
1 Request timed out.
2 The packet length as received from theEthernet device was not big enough to be a valid
TFTP packet.
3 The received packet was not from the server specified in the server command.
4 The IP header length was not big enough to be a valid TFTP packet.
5 The IP protocol type on the received packet was not UDP, which is the underlying
protocol used by TFTP.
6 The received IP packet's destination address did not match the address specified by the
address command.
7 The UDP ports on either side of the connection did not match the expected values. This
means either the local port was not the previously selected port, or the foreign port was
not the TFTP port, or both.
8 The UDP checksum calculation on the packet failed.
9 An unexpected TFTP code occurred.
10 A TFTP transfer error occurred.
-10 The image file name you specified cannot be found. Check the spelling of the filename
and that permissions permit the TFTP server to access the file. In UNIX, the file needs to
be world readable for the TFTP server to access it.
11 A TFTP packet was received out of sequence.
