Hi all,

I have FTP case, i suspected that what caused it

In my lab, Two Cisco 2811 connected together with back-to-back interface with clock rate 256Kbps

I tried to FTP file from flash memory of router to server but it not completed such as I would like to get file 1.5 MB from router but i received only 1.4 MB!!!

I tried to change the files size to smaller/ larger and change speed as well but i getted the same result. I did not sure this cause come from Router or IOS. Could anyone advice me about this case?

PS. I getted the code from FTP application, 221 Services closing control connection

      I transfer file between PC through these router, succeed

Hello Decho,

Which IOS version are you using this router?

From the description it could be anIOS bug,

for example:

CSCsx46421 File Transfer aborts with the Active FTP


You migth try to test the described Workaround:

Use Passive FTP ("ip ftp passive" on problematic router) for the FTP

file to be properly transferred.

and consider an upgrade to one of the release with the fix.
