From an tftp server I'm trying to import the config to startup-config using 

copy tftp startup-config 10.0.0.10 5006zl.cnf

The switch asks for confirmation y/n and when pressing y it just aborts saying that the config could not be loaded.

show logging -r shows 

W 09/03/17 06:08:11 00158 update: AM1: line 0. Action is ignored in download
            mode.

Flash information about the switch: show flash

Running config on the switch: show running-config

; J9850A Configuration Editor; Created on release #KB.16.02.0020
; Ver #10:08.01.81.b3.ff.7c.59.fc.7b.ff.ff.fc.ff.ff.3f.ef:5a
......
......

Config on the tftp server is also 

; J9850A Configuration Editor; Created on release #KB.16.02.0020
; Ver #10:08.01.81.b3.ff.7c.59.fc.7b.ff.ff.fc.ff.ff.3f.ef:5a

My suspicion is that the versions of running-config and show flash don't match. Is this known? How could I solve this?

  • This may be due to invalid line breaks in the config on the TFTP server - all errors refer to line 0. You should check whether each line is terminated by \n (linefeed). – Zac67 Sep 05 '17 at 11:09
  • @Zac67 I've checked that though and all lines are terminated by `$`. See update. – Valentin Bajrami Sep 06 '17 at 07:54
  • As a test, try uploading the current conf to the TFTP server, and then check the line breaks in the output from the switch. Is this issue affecting several switches that you've tried to download this conf to, or just a single switch? – Stuggi Nov 27 '17 at 09:20

Incidentally, I stumbled on a likely explanation for the described problem. Your suspicion is most probably correct: the switch does seem to verify the firmware version in the config with the actually running version.

When exported using the add-ignore-tag option, the first line is changed to e.g.

; J9850A IGNORE Configuration Editor; Created on release #KB.15.18.0013$

If you edit the config to be imported in the same way it should work, regardless of the firmware version.

    Hi Zac. Thank you for your reply. Unfortunately I cannot verify this answer sinice I don't work at that company anymore but I assume this could be the correct one. `add-ignore-tag` might be of importance here. I did not know such thing existed so glad I learned something new today. Viel dank! – Valentin Bajrami Jul 21 '21 at 13:42
