Chapter Summary

As you begin to build an internetwork, the first thing you have to consider is the physical implementation of the LAN and WAN connections. These considerations include speed of services, infrastructure, and physical interfaces. This chapter discussed how Ethernet physical layer standards correlate to the infrastructure that you have to install to use the services. This chapter also reviewed the connection differences for WAN connections and how to connect to a console or AUX port for management of the device.
