■ Finance
■ Protocol-sensitive VLAN using the IP protocol
■ Ports 1 and 3 have been assigned

■ Personnel
■ Protocol-sensitive VLAN using the IP protocol
■ Ports 2 and 4 have been assigned
■ IP address 192.207.36.1
■ MyCompany

The stations connected to ports 1 through 4 generate a combination of
IP traffic and NetBIOS traffic. The IP traffic is filtered by the
protocol-sensitive VLANs. All other traffic is directed to the VLAN
MyCompany.
