Hi,
I've got a C3750G-24T that I'd like to boot over tftp, but it just isn't working. I know that the tftp server is working correctly and have tftp copy'ed files between the switch sand the server.
The boot system line is
#sh boot
BOOT path-list : tftp://192.168.9.21/c3750-ipbase-mz.122-35.SE5.bin
The boot loader is "BOOTLDR: C3750 Boot Loader (C3750-HBOOT-M) Version 12.2(25r)SEC, RELEASE SOFTWARE (fc4)".
Any help?
Thanks,
Mark

Mark,
By default, a configuration register setting that tells it to boot using the first IOS image stored in Flash memory. If a valid IOS image isn’t found in Flash, it will then attempt to “netboot” using an IOS image stored on a TFTP server. If even this fails, the default configuration register tells to boot using the image stored in ROM.
The following example shows a router configured to boot from an image in Flash, followed by an image stored on a TFTP server
Router(config)#boot system flash c3750-js-l.120-7.T
Router(config)#boot system tftp c3750-js-l.120-7.T 192.168.1.100
After issuing the boot system commands, they can be viewed using show run.
Hope to Help !!

Hi Ganeshh,
Thanks for your reply. Those commands did not work. Firstly, the IOS (c3750-ipbase-mz.122-35.SE5.bin) would not retain two boot lines. Only the last one entered survived. Secondly, the syntax above did not work. Here is the help output:
switch(config)#boot system ?
WORD pathlist of boot file(s) ... file1;file2;...
switch Set system image for switches in the stack
