3com 4200G :

 

I want to save the configuration by "Administration ... Backup configuration ...", but how does TFTP work? Where can I put the ftp-username & password?   I have a FTP server running on another machine; when I give that IP address, it starts "backup configuration software", but then a dialog opens "transfer file error".

 

Thanks!

#tftp

You dont need to use username and password when using TFTP, maybe you have mixed up TFTP with FTP?

Please install a TFTP server on your machine and try again.

yes, understood that now, when looking into software on this page:

  http://h17007.www1.hp.com/us/en/support/converter/index.aspx?productNum=JE016A

  E4200_24G_Switch_v.1.05_3Com_TFTP_Server_1.05.exe

Have done that now.

 

Installed it on a windows machine which is connected to that switch.

 

This operation backs up the saved configuration file of this device to the TFTP server.

[...]

IP address: 192.168.x.y

Remote filename: config.cfg

 

Unfortunately: Still the same behaviour.

Transfer File error!

 

 

any ideas what to try next?

 

Do you have real connectivity between the switch and tftp server?

Dont know what TFTP server you use, but do you see any logs in it?

 

 

This is a great TFTP server to use: http://tftpd32.jounin.net/

 

 

> what TFTP server you use

That was not the problem. http://tftpd32.jounin.net/ and the "3com TFTP server E4200_24G_Switch_v.1.05_3Com_TFTP_Server_1.05.exe" actually BOTH work now.

 

The answer was hidden somewhere else :-)

 

"Administration ...  Backup configuration ..." only worked after I had pressed "Save configuration" for the first time, which was "invisible" because it was not hidden in a sub-menu, but in at the top level. Hidden in plain sight, so to say.:

"Unit1 save configuration flash:/3comoscfg.cfg successfully"

 

[Looks as if the configuration was never saved before, somehow strange behaviour, isn't it?]

 

Now it works flawlessly to store the configuration remotely:

• Backup from:     Unit ID 1    4200G
• Saved to the TFTP server:      IP Address192.168.42.155   Remote filename:cfg.cfg
• Backup complete.

 

Yippieh. Thank you very much!

 

 

 

Hi

 

im on - 3Com Switch 4200G 48-Port Software Version 3Com OS V3.01.00s56 -

 

i know, a little older :-)

 

but i have the same error...no matter what tftp server use.

 

is there any way to do it without upgrading OS?

 

regards

make sure to disable any firewall on the machine having tftp server as it sometimes block the connection, and try pinging from both sides

no firewall on any side....

 

as another clue, using telnet to connect to the switch...

 

 tftp 192.168.30.10 get hello.txt       -->   works fine!

 

but

 

 tftp 192.168.30.10 put 20120322.cfg      --> fails

also

tftp 192.168.30.10 put unit1>flash:/20120322.cfg and other combinations.

 

 

regards

Since get works but not put, are you sure you have got write permissions on the tftp server?

solved.... im using a tftp server in linux, and in the server config i have to add a "-c" option in the daemon startup to accept files that not exists in the destiny. regards
