I’m a master of the DOS/Windows terminal. I’ve been using it for over 35-years. I remember F3 will repeat the previous command in DOS v. 6.3. Put me in a room, and I could edit a batch file with the best of them. Therefore, I have years of muscle memory. The sunk cost highlights the problem of changing technologies vs. culture.
We are knee-deep in our Juniper Apstra testing. It is an excellent tool for automating network configuration. Take, for example, knowing how to configure BGP on an Arista DCS-7050T versus a Juniper QFX10002. Instead of needing to learn the arcane command lines of each switch, you only need to know the intent and the way to implement that intent via the automation tool.
The ability to automate the configuration sounds ideal on paper. In reality, I already know the commands to issue on both devices. I don’t know how to do it in Apstra yet. I have a deadline to meet for this project. Guess which route I took? You don’t need BGP to know.
How have you overcome a learned culture when implementing change?
