I had tried multiple things like swapping out the Ethernet cable, re-downloading the the update file, I had even tried using a different computer, and different TFTP software – however ended with the same result. 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. The opcode command is used to instruct the switch to download the file into Flash memory.Recently I was trying to upgrade the IOS version on a Cisco 3750 Layer 3 Switch. In this example, the image to be downloaded from the TFTP server is named cat1900EN_9_00.bin. However, it does allow you to download a new IOS image from a TFTP server. Unlike with a Cisco router, a Cisco 1900 series switch does not allow you to upload its IOS image to a TFTP server. TFTP successfully downloaded configuration file The command to copy this same configuration file from the TFTP server back to the switch is shown below. In this example, the contents of NVRAM (the configuration file) are copied to a TFTP server at 192.168.1.31, with a filename of config-1912. The example below shows the configuration of a Catalyst 1912 being backed up to a TFTP server at address 192.168.1.31.Ĭonfiguration upload is successfully completed The syntax to copy the configuration of a Catalyst 1900 series to a TFTP server is different than on a router, although it does following a similar “copy from to” format. Much like with Cisco routers, it’s generally a good idea to back up the configuration of your switches as well.
