Although VLANs are commonly used to create individual broadcast domains
and/or separate IP subnets, it can be useful for a server to have a presence on more
than one VLAN simultaneously. Several Sun products support multiple VLANs on a
per port or per interface basis, allowing very flexible network configurations.

Example of Servers Supporting Multiple VLANs With Tagging Adapters
FIGURE 4-1
The example network has the following features:
The physical LAN network consists of a switch, two servers, and five clients. The
LAN is logically organized into three different VLANs, each representing a different
IP subnet.
VLAN 1 is an IP subnet consisting of the Main Server, Client 3, and Client 5. This
represents an engineering group.
