The assumption is that they’re creating a high bandwidth trunk interface to the L3 switch/router, so if they forget to create an aggregate it’ll be two independent interfaces and will down the network (or a port will auto down itself with STP, MSTP, etc. but that’s not as funny)
A router of industrial scale which i see at work has its ports to be l3 ports by default. They don’t down the network as the router rejects config where two ports are given the same subnet… at least the ones i operate at work.
That’s true, the default for layer 3 switches is to have its port set as routable.
The original joke really kinda falls flat with modern tech, but it’s still funny to think about handing a switch to someone with zero knowledge and then watch as they accidentally lock up the environment.
It doesn’t.
