I am trying to install a license through tftp in the CLI of a Cisco 2504 controller. My computer is a Mac Pro running Mojave version 10.14.6.

I have enable the tftp server on my mac. When I do netstat -na |grep \*.69 I see the following:

udp4       0      0  *.69                   *.*                               
udp6       0      0  *.69                   *.*

My computer has the ip address 10.0.11.156 on the network. I have installed the license in the /private/tftpboot directory. I also did chmod 766 on the /private directory /private/tftpboot and the license file itself.

I am able to get files by tftp from other machines on the network. On another computer on the network I entered:

tftp 10.0.11.156
tftp> get [license filename]

I got the response:

received 2236 bytes in 0.1 seconds

But when I go to the controllers CLI and enter

 (Cisco Controller)> license install tftp://10.0.11.156/[license filename]

the cli says Transfering licenses from tftp://[license filename], then hangs for about a minute then responds 

% Error: License file transfer failed - No reply from the TFTP server

In short, I'm able to tftp the file from another computer, but I get no response from the server when trying to install a license.

I forgot to add that I am able to ping from the controller to 10.0.11.156.

How do I install my license on my controller?

No reply from the TFTP server means communication from the TFTP server back is not working.

  • Make sure the correct port is open. If you say you can make transfers from another PC this may be fine, but check anyway.

  • Make sure you do not have multiple WAN/network connections on the computer you use because routing may mess things up and your return packets may end nowhere because they try to return via another route/path. If you do, disable the unneeded one or use administrative distances to make the default route the correct one.

What worked for me was to hardwire a windows machine directly into the network instead of using the wifi, then used the tftpd64 app.
