Where do I store the configuration file for my cisco router in the TFTP Server?Ĭurrently, I have created two temp folders in /var/lib/tftpboot- ls -lĭrwx- 2 tftp tftp 4096 Mar 31 15:37 ExrZHRa-incomingĭrwxr-xr-x 2 root root 4096 Mar 31 15:52 treeĪs per Cisco's documentation, this is the syntax to get a file from TFTP server- copy tftp: /directory ]/filename ] nvram:startup-configĭevice# copy tftp://server1/dir10/datasource nvram:startup-configĪs per my understanding, the location will be IP of my TFTP Server and filename will be the actual config file I want to load. I want to configure my cisco ios routers to take configuration from this TFTP server at boot time. I increased it to 5 and 10.I have a Ubuntu machine which acts as a TFTP Server.

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.
