TFTP Download Error Codes
PDM cannot be downloaded via TFTP from the PIX Firewall unit’s monitor mode. You must use the
copy tftp flash:pdm command described in
Chapter 3, “Installing PDM.”
During a TFTP download, non-fatal errors may appear in the midst of dots that display as the software
downloads. The error code appears inside angle brackets.
Table A-1
lists the code values.
For example, random bad blocks appear as follows:
....<11>..<11>.<11>......<11>...
Also, the display may show “A” and “T” for ARP and timeouts, respectively. Receipt of non-IP packets
causes the protocol number to display inside parentheses.
Error codes 9 and 10 cause the download to stop.
