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, respectively.
