I am trying to upgrade the firmware on a Cisco SFE2000P 24 port switch. The only option for upgrade is TFTP. I downloaded a copy of Solarwinds Free TFTP server. Installed it on one of my servers without a problem. I uploaded the firmware file into the TFTP directory. When I attempt to GET the firmware from the TFTP server, I get the following messages.
