Resolution

Engineer's Toolset uses the TFTP server to transfer configuration files for Cisco devices.

Note: If the ports are not correctly set, the download and upload will fail. Do not change the ports unless necessary.
 

  1. Go to the TFTP Configuration page. 
  2. Verify that traffic is allowed on the following ports and that these are not being used on the computer where ETS is installed:
    • UDP/69 - The TFTP server uses this port for TFTP transfers.
    • TCP/8099 - The TFTP server uses this port for user interface to TFTP service traffic.
