How do I boot a Cisco ios from a tftp server?

I tried putting the command:

boot system tftp nameIOS.bin 192.168.0.2

but still doesn't work....

thanks in advanced

Re: booting IOS from tftp

If 192.168.0.2 is not directly connected, make sure that you have the ip default-gateway command configured and pointing at the proper GW address.

If 192.168.0.2 is directly connected then you might want to make sure that the TFTP server is probably configured and responding.

Hope this helps,

Re: booting IOS from tftp

yes, I got a cross-over cable connected from the TFTP server to the router and TFTP is working fine.

I can also ping the tftp server from the router.

I want to know if there is any other configurations,

like config-register, etc..

problem is that I already have a IOS in the flash...

Re: booting IOS from tftp

That's OK, you could have another IOS on the flash.

Can you make sure, TFTP application is fired up on your PC and the root directory on your TFTP application is pointing to the location where the IOS is residing.

If you have TFTP running then do you see TFTP request come in and does the application generate any error. Also, make sure if you are running windows on your PC the firewall feature on it isn't blocking TFTP.

If the IOS is in the temp folder on C Drive, if you specify C:\ as the root directory location that's good enough.

TFTP application should show the progress of file transfer when the image is being copied.

HTH,
