Overview of Ports and Interfaces
Three concepts are key to understanding how controllers connect to a wireless network: ports, interfaces,
and WLANs.
Ports
A port is a physical entity that is used for connections on the controller platform. Controllers have two
types of ports: distribution system ports and a service port. The following figures show the ports
available on each controller.
Note The controller in a Cisco Integrated Services Router and the controllers on the Cisco WiSM do not have
external physical ports. They connect to the network through ports on the router or switch.

Note Figure 3-2 shows a Cisco 4404 controller. The Cisco 4402 controller is similar but has only two
distribution system ports. The utility port, which is the unlabeled port in Figure 3-2, is currently not
operational.
