Re: 4500 boot

There seems to be an issue with your TFTP server. Tftpd32 is a great TFTP server but can be a little more complex than it should be. I keep a folder on the C: drive called TFTP with all the TFTP contents and keep the security at none. If you want to try something a little easier I also recommend solar winds TFTP server.



PS: Don't forget to disable or allow TFTP access temporarily through your desktop firewall if you have one.

Re: 4500 boot

For time reasons not was possible continues troubleshooting with the tftp server. I just use a Compact Flash in the slot0 with the ios. after boot i just copy the ios to the bootflash and change the boot variables.

I believe the problem is the BOOTLDR variable. But I don't had time to test it.

Re: 4500 boot


You can find the values in the link I posted before to configure the BOOTLDR variables.

Re: 4500 boot


I had the same problem.

Just upgrade to the latest version of tftpd32 and everything worked fine!
