i'm in the process of upgrading a switch and ever time i try to copy the file over this is what i get.Can you tell me what might cause this

RTR1#copy tftp flash:

Address or name of remote host []? 10.2.X.X

Source filename []? cbs30x0-ipbase-mz.122-50.SE1.bin

Destination filename [cbs30x0-ipbase-mz.122-50.SE1.bin]?

Accessing tftp://10.2.X.X/cbs30x0-ipbase-mz.122-50.SE1.bin...

Loading cbs30x0-ipbase-mz.122-50.SE1.bin from 10.2.X.X (via Vlan5): !!!!!!!!!!!!... [timed out]

%Error reading tftp://10.2.X.X/cbs30x0-ipbase-mz.122-50.SE1.bin (Timed out)

That's right. Just substitute the "file name" with the correct value. :)

First make sure you can ping from TFTP server to the switch and the other way around.

If that works then make sure the image is in the root of the TFTP (name of the image is case sensitive, make sure is exactly the same).

Also, check that the TFTP has the send and receive options properly configured.

Hope it helps....

The file is starting then timing out.

You probably don't have enough room in flash.

Try this:

"dir flash:"

verify you have enough free space

If not enough do this:

"delete flash:'name of older ios or unused files'"

you know that was the first thing that i check,the file is 8MB and i have 24MB free

Hmmm. then I'm sorta stumped as to what would cause the file to start copying over then stop unless maybe the flash is corrupted or has a bad disk area

"fsck flash:" maybe?

Ok Greg

I figured out what it was,i have to have udp high ports enabled so that the bin file would load properly.But now i have one more i have to make the new bin that i've load the perferred choice upon next boot with the old bin as back up.What commands do i need to enter to do this.

Go to configure mode:

no boot system flash:

boot system flash:

boot system flash:

so what i should do is get into config mode and do this

RTR#config T

RTR(Config)boot system flash:file name
