- Figure 7 61 the client figure 7 61 the client 110
- The client is simply the endstation that wishes to gain access to the lan or switch services all endstations must be running software that is compliant with the 802 x protocol for users running windows xp that software is included within the operating system all other users are required to attain 802 x client software from an outside source the client will request access to the lan and or switch through eapol packets and in turn will respond to requests from the switch 110

- Figure 7 63 example of typical port based configuration 112
- Network access controlled port 112
- Network access uncontrolled port 112
- Once the connected device has successfully been authenticated the port then becomes authorized and all subsequent traffic on the port is not subject to access control restriction until an event occurs that causes the port to become unauthorized hence if the port is actually connected to a shared media lan segment with more than one attached device successfully authenticating one of the attached devices effectively provides access to the lan for all devices on the shared segment clearly the security offered in this situation is open to attack 112
