[MuzzyRocket]

Hi, i have few catalyst switches (2960, 3750) and i can't upload to them any files by tftp from my laptop, but i can download from them, and this bug don't appears on two routers.

sw01#copy tftp://10.10.47.27/sample.conf flash:

Accessing tftp://10.10.47.27/sample.conf...

Loading sample.conf ... [timed out]

I was change tftp server, type of connection (wifi, cable), turn off firewall on win7, but nothing helps me.

HI Aleksanddr,

Step 1:

I am not sure about this problem but still you can try this:

Put TFTP in ASCII mode and 2nd time switch to Binary mode.

Try with both mode.

May be it helps.

if still falied then use Step2:

May be its due to the large files.

1. images do not support more than 16MB in size for Trivial File Transfer Protocol (TFTP).

Its better to use FTP.

here is the method about how to use:

Is it possible to try the operation using ftp? See this:

Thanks for answering, i found solution - one of tftp server (Winagents) works incorrectly and run as service, when i close it, service will didn't stop, and other tftp server can't use port 69.
