I was using my laptop with Tftpd running serving the update IOS file.

This was very much a lab setting, no other devices involved. The switch was not in production so the traffic workload was simply the TFTP traffic between the switch and the admin PC. This was puzzling because the setup was rather simple. Switch#copy tftp flashĪddress or name of remote host? 172.16.16.2 However, I kept getting timeout issues – see below.

Recently I was trying to upgrade the IOS version on a Cisco 3750 Layer 3 Switch.
