Problema al cargar la IOS a un switch 3750v2

Buenas tardes.

No puedo cargar el ios: "c3750--ipbasek9-mz.150-1.SE3.bin"   a un switch 3750v2. El ios pesa 15.698 KB.

El procedimiento que realice fue el siguiente:

Switch#copy tftp: flash

Address or name of remote host [192.168.1.36]?

Source filename [c3750-ipbasek9-mz.150-1.SE3.bin]?

Destination filename [c3750-ipbasek9-mz.150-1.SE3.bin]?

Accessing tftp://192.168.1.36/c3750-ipbasek9-mz.150-1.SE3.bin...

Loading c3750-ipbasek9-mz.150-1.SE3.bin ... [timed out]

%Error reading tftp://192.168.1.36/c3750-ipbasek9-mz.150-1.SE3.bin (Timed out)

Switch#

lo he probado con 2 tftp diferentes, borre el flash actual para asegurarme que haya espacio suficiente y aún sigue saleidno ese mensaje de error.

Por favor, ayudeme con esto.

Gracias de antemano.

Your switch cannot "see" the TFTP server.

Check your cable.

Firewall.

Check your IP addressing.

Can the switch ping the TFTP server IP address of 192.168.1.36?

Hi.

The cable is ok.

The windows firewall and the antivirus are off.

My TFTP Server is with the IP 192.168.1.36/24 and the switch 3750v2 is with the IP 192.168.1.10/24

The switch can ping to the TFTP Server.

I did this testing:

I can backup the startup config of the switch in the TFTP Server

I can copy the actual IOS of the switch in the TFTP Server

I can download a config from TFTP Server to the switch

But I can´t copy a IOS from the TFTP Server to the switch.

I saw the same problem in Internet, but no body have a answer.

Hi !

I tried with FileZila Server, Cisco TFT¨P and other 3 more but the problem is the same.

As I erase the actual IOS, I am doing this steps:

I push the "mode" botom, then I write this comands:

switch: flash_init

switch: copy xmodem: flash: c3750-ipbasek9-mz.150-1.SE3.bin

The IOS is sending from My computer to the switch, but is very slowly.

I tell you when I finish.

You can speed up the process by "bumping" the xmodem baud rate to 115200 bps instead of 9600 bps.
