Network Diagram
Ideally, you should have a network diagram, showing the switches at each
location and the endpoints that connect to each switch. The diagram should
list network subnets and VLANs for each switch. It should also show:
■ Router or VPN gateway that controls remote access
■ DHCP servers and the switches to which they are attached
■ Network access zones—private wireless, private wired, public wireless,
and public wired
