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.

Table 2-3lists the TFTP error codes.

The packet length as received from the Ethernet 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.

7The 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.

8The UDP checksum calculation on the packet failed.

9An unexpected TFTP code occurred.

10A 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.
