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
