Dear All

I followed the instruction from the Document "Cisco Branch Router Series (NME-NAM) Installation and Configuration Note, 4.2" and the URL is ""

to upgrade the NAM application software. I got the error message (in RED):

     Download NAM application image via tftp and write to HDD

     server IP address []:

     full pathname of application image []: nam-app-x86_32.4-2-1.bin.gz

     Getting nam-app-x86_32.4-2-1.bin.gz from via tftp.

     tftp> tftp> tftp>

     zcat: stdout: No space left on device

     upgrade.bin size: 73474048

     File transfer successful.

     Checking upgrade.bin

     bad magic number.

     bad magic number.

     File upgrade.bin is not a valid NM-NAM application image!

The error message seems to me I do NOT have enough space to download the NAM application image, but I could be wrong. However I shall have enough space on the HDD to save the image file.

My equpiment details are below:

Indeed it's saying that you don't have enough space left, and the image downloaded is then incomplete. Have you checked how much space left you have? As I see the image, you need at least 80MB.

Maybe you can delete some old files.

If this advice helps, please rate it!

Thank you!

Dear Calin

I have about 63GB free disk space. I assumed the application image would be downloaded to the hard disk, But it seemed not the case.

I was running into the same issue, I believe this has something to do with the way tftp works on this device.  When I copied the application binary to an FTP server and downloaded onto the device the process completed successfully:
