TFTP Issues with ICX 7150

[kringnalda]

Hello all,

I'm currently in the process of taking backups of each of our network switches, and I'm running into an issue with how they interact with my TFTP server. I'm using Tftpd64 on Windows 11, but I've also tried to use SolarWInds TFTP server. When I connect to almost any of my switches and run the following:

copy running-config tftp <server ip> <filename.txt>

The switch outputs:
Parameter Validation Successful
....File Upload Complete

And my TFTP server log reads:
Connection received from <switch IP> on port 36473 [12/09 10:26:58.411]
Write request for file <test1.txt>. Mode octet [12/09 10:26:58.412]
OACK: <blksize=8192,tsize=7521,> [12/09 10:26:58.415]
Using local port 56325 [12/09 10:26:58.415]
<test1.txt>: rcvd 0 blk, 0 bytes in 1 s. 0 blk resent [12/09 10:26:59.435]

It creates the file with the specified name, but the .txt file contains 0 bytes. I tried this on every single switch we have, and it only worked successfully on 4 of them, which tells me it's not likely an issue with the TFTP server or our firewall. I'm honestly not sure what to try next, so any help would be amazing.

Hi Kringnalda

Thank you for reaching us

Could you help me with below details 

• Is the Solarwind TFTP server located in same site or different site ?
• Have you tried testing using different TFTP server like tftpd32 ?

Also please run through the below article and check if it helps. The access to the below article would need you to login to the ruckus portal.

Thanks

• Yes, all devices are spread throughout several buildings, but are all within one network together. I'm able to ping the switches from the TFTP server and vice versa without issue.
• I've tried both SolarWinds and Tftpd64, not 32.
  
  I followed the link you sent, but it appears to be a sales contact form, not a support article.
