I ran into this today and it sounded interesting enough to share it with you. I increased it to 5 and 10.As you can see from my article list, I’m going through some VRF configuration in the last few weeks 🙂 So, I tried two things: First I increased the Timeout and Max Retransmit settings in Tftpd. Second, was that during the initial transfer there seemed to be some negotiation of transfer rate that Tftpd was trying to do. I did notice a couple of things with the TFTP: first, that in the Tftpd window was that the error counter was ticking up throughout the transfer process. Deleting a folder on IOS takes a few more options than just deleting a file: Switch#delete /recursive /force flash:2 There was folder that contained the current version of IOS running on the 3750. I did see that space was a little tight on the flash memory. 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. Recently I was trying to upgrade the IOS version on a Cisco 3750 Layer 3 Switch.
