I've been having trouble with a little RPI Kubernetes cluster on my school's network, and I think the issue has to do with DHCP. Problem is, I don't really understand a whole lot of networking stuff, let alone DHCP. Could anyone ELI5?

EDIT: Thanks to the help of the campus "networking guy," I believe we've fixed the issue. Apparently wired interfaces get shut off after a while if they aren't "chatty." While my cluster is chatty by virtue of being a cluster, since it's all on the same ethernet switch, that doesn't really matter. While an actual fix would be to investigate interface shutdowns on non-chattiness, the temporary fix?
