Several hotspots are located on a University campus. They provide access to the library server and the Internet for students with WLAN notebooks. The hotspots are connected to the University's LAN. This LAN is also used by administrators, who access the base stations to perform various management tasks via SNMP.
Setting up a virtual LAN between the base stations and the administrators' switch serves to protect the management traffic from the "public" traffic on the LAN.
