Could provide me the entire step by step process for IOS upgrade in ur router?

Then  i will guide you

View solution in original post

Daft question - is windows firewall off, and no access-list on the router?

Also, can you try another tftp daemon - i recommend tftpd32.

Failing tftp, you can try anpother transport protocol - ftp or scp should work okay.

Hi aleemuddin

I would guess at a syntax problem, but could you post your copy command and the console output?

Regards, Ash.

Really thanks for your interest.

I have attached JPG file,snap shot

Okay, try this command instead:

copy tftp flash://10.0.0.1/c2801-advipservicesk9-mz.124-15.XZ2.bin

It looks like your Windows is not set to display filename extensions - .bin should be the extension type for this file.

Regards, Ash.

hi Ash,

i applied the given command but same error, although file extension is .bin now.

pls. see attahced file. thanks

hi,

kindly see the attached file details

Can you create a test file in your tftp root, named test.txt?

Then try and tftp transfer this file:

copy tftp flash

10.0.0.1

test.txt

test.txt

Regards, Ash.

hi, Ash.

I tried tftp32 suggested by you and it worked smootly. the bin file is transfted successfully now.

now i can see 2 ios: the old is still exist, then should i delete the old ios so the new will automaticlly boots?

pls see attached and guide.

Thanks once again.

can you able to ping the TFTP SERVER from router?

Hi Boopathi,

The OP screenshot shows a successful ping to 10.0.0.1.

Also, the tftp server output shows connection attempts (TFTP GET) so i think we have at least L3 and half L4 connectivity.

Hence a test of a simple file transfer using test.txt.

Regards, Ash.

Ah good work!

You can leave the old file there for backup (only delete it if you need the space).

To boot to the new ios, use the:

boot system flash:

command, then write mem and reload.

You can do a show boot to see the correct syntax, it may be boot system flash:/

Good luck!

Ash.

hi Ash,

at configuration level the command is boot system flash

Router(Config)#boot system flash c2801-advipservicesk9-mz.124-15.XZ2.bin

Router(Config)#

Router(Config)#wr mem

Router(Config)#

all commands accepted so i reload the router but again the old IOS boots.

pls advise.

Hi,

Firstly, I'm not convinced that's the correct boot command, I would expect something like this:

boot system flash:c2801-advipservicesk9-mz.124-15.XZ2.bin

or

boot system flash:/c2801-advipservicesk9-mz.124-15.XZ2.bin

Secondly, you may already have another boot statement which is interfering with this new IOS - check this with the show version command to see what IOS is booting.

OIf you have, delete the command and write mem, reload.

Regards, Ash.
