Hello,
I am trying to get a cisco 7204VXR w/ a NPE-225 to boot its IOS image from a tftp server.
I can access the TFTP server just fine. My interface f0/0 and the tftp server are in the same subnet (directly connected).
The boot statement says: boot system tftp <iosname> <IP>
After a reload the router hangs for a long time and then logs a message, that he was unable to load the image via tftp:
%Error opening tftp://<ip>/<image> (Timed out)
and continues to boot the file in the flash.
When I connect a sniffer, I see no packets leaving from the router, so no tftp requests anything.
I already tried several different ways to sell the tftp statement (boot system tftp and boot system tftp://), but nothing changes.
Which interface will the router use to connect to the tftp server? not the onboard interface on the npe?
I am really swamped.
Any help would be greatly appreciated.

Hi,
you need to Enable booting from a Trivial File Transfer Protocol (TFTP) server,
setting the Configuration Register
The configuration register can be set in the configuration mode with the config-register 0x value command. See the following sample output:
Router# configure terminal
Enter configuration commands, one per line. End with CNTRL/Z.
Router(config)#config-register 0x2142
Router(config)#end
Router#
%SYS-5-CONFIG_I: Configured from console by console
Boot Field Meaning
0
Stays at the system bootstrap prompt (ROM monitor) on a reload or power cycle
1
Boots the boot helper image as a system image
2
Full boot process, which loads the Cisco IOS image into flash memory
2-F
Specifies a default filename for booting over the network from a TFTP server
