I am trying to boot a WS-C3550-24 from a TFTP server but it is not working. I am using the "boot system tftp://x.x.x.x/imagename.bin" command, and I do a wr me. When I do a "show boot" it shows that it is configured for the appropriate tftp server. When I reload, I get the message that the file is not authorized. I already verified with a test file that this switch can access the server. (I am using Tftpd32 on a laptop by the way on a routed port coming directly off the switch. Also there are no firewalls.)
I would appreciate any suggestions!
