Boot from network via TFTP

[Zeeeee]

Hi Guys,

My 6509 has no TFTPdnld in rommon. Will I still be able to boot network tftp or boot system tftp?

I have googled and tried a few examples but to no avail.

Thank you in adv.

Hi,

So, in rommon when you issue "set" there is no tftp available?

Hi Reza,

Thanks.

Hi,

Can you issue the "set" command and post the output here?

Also, have you look at this document?

Hi,

Ok, so tftp command is available when in rommon. Can you follow this link:

Hi Reza,

I do not think it works for this case. Please see below:

monitor: command "tftpdnld" not found
rommon 5 > ?
alias set and display aliases command
boot boot up an external process
break set/show/clear the breakpoint
confreg configuration register utility
cont continue executing a downloaded image
context display the context of a loaded image
dev list the device table
dir list files in file system
dis disassemble instruction stream
frame print out a selected stack frame
help monitor builtin command help
history monitor command history
meminfo main memory information
repeat repeat a monitor command
reset system reset
set show all monitor variables
stack produce a stack trace
sync write monitor environment to NVRAM
sysret print out info from last system return
unalias unset an alias
xmodem x modem download
rommon 6 >

There is not tftpdnld for me to run.

Thanks!

Hi,

I see, the command is not available.

If there was one, it would look like this

tftpdnld					tftp image download

Aizat, 

Is this thread a DUPLICATE of THIS?

[Zeeeee]

Hi Leo,

Oh no it is not. There was no IOS at all and I was trying to find out if there was any way to load IOS besides xmodem since i do not have any cf card, for that thread.

There was no way so I used xmodem. After booting up, saved a copy in bootdisk and now trying to boot via tftp server.

Hi

I think tftpdnld is not available on these devices, please check this link to know how to upgrade it via Rommon, you can use:

Cat6509-E (enable) copy ftp disk0:

http://www.cisco.com/c/en/us/support/docs/switches/catalyst-6500-series-switches/28724-161.html

You will find how to upgrade over different sup modules.

Hope it is useful

:-)

Hi Julio,

Thanks for sharing. I am able to copy ios via tftp. The issue is actually to boot from tftp, instead of bootdisk or cf card.

Thanks!

Just been manage to LAB it and get it working. Not sure if you have to type in sync after all the variables, it uses the management port Ethernet Port at the front of the router.  You can’t ping the IP address set i.e 192.168.1.79.
