Hardware & Networking Scope

Training and on-the-job experience are the only ways to become a network admin. Here are some steps:
Learn about how network protocols help to make a network work properly. L1, L2, L3 and L4.
Ethernet - L2 routing, ARP, STP, etc. IP - L3 routing, RIP, OSPF, etc. TCP/UDP - How packets are built and interact with the network. You would then learn vendor-specific tools/commands to make a network work and route packets correctly. At the end of the day, all networks work the same way, the only difference is what commands specific hardware required to make them work.
