Hi,

I'm having problems to TFTP image files using a 2530 switch.

My TFTP server is located on another subnet.

If I TFTP from my Cisco switches on the same network, it's working fine.

However, I actually can TFTP configuration files using the 2530.

Is this a software bug?

Is there any logging on the TFTP server?

I'm using atftp, the output shows that there is actually being blocks transfered but then it stops. Tried changing block sizes back and forth.

Worked when using tftpd64 on my windows machine, no idea why it doesn't work on Ubuntu.

Hi lads,

I ran into a similar problem with my 2930F switches. I am building a zero touch deployment including a firmware update configured via the DHCP options. I ran into the problem that the first three packets of the firmware were transferred and then the switch sent an ICMP Destination Unreachable/Port Unreachable. The switch retries to transfer four times and then aborts and continues to load the configuration file.

I have found out that this is only done if the current firmware of the switch matches the firmware to load. Only if the firmware is a different one loading it is successful. Tested with upgrade from version WC.16.07.0003 to WC.16.10.0005.

After the switch has booted I am still able to just copy the same firmware over the flash primary without any issues. I am using tftpd-hpa version 5.2+20150808 on ubuntu18.04 LTS.

I am posting this here because when analyzing this I stumbled across this thread. I can also thereby confirm that tftpd-hpa is working with the HP switches.
