Several hot spots are installed on an university campus, so that students equipped with notebooks and WLAN cards have access to the Internet and to the server of the library. The hot spots are connected to the university LAN. Via this LAN the administrators also access the base stations to carry out several management tasks via SNMP.
By setting up a virtual LAN between the base stations and the administrator’s switch, management data is shielded against all “public” traffic on the LAN.
