Hello
We are about to rollout 500+ Cat3K Switches and we are trying to deliver the new configs via TFTP but it’s not working and I think we have worked out why, in IOS XE 16.x.x the block size appears to have changed, how do we work around this without manually getting involved with console cable which will render the process we are implementing null and void? Below is the error and my testing that shows out of the box the block size is 8192, could it be as simple as looking at a newer TFTP service?
