Although VLANs are commonly used to create individual broadcast domains and
separate IP subnets, it is sometimes useful for a server to have a simultaneous
presence on more than one VLAN. Marvell adapters support multiple VLANs on a
per-port or per-team basis, allowing very flexible network configurations.
Figure 3-1. Example of Servers Supporting Multiple VLANs with Tagging
Figure 3-1 shows an example network that uses VLANs. In this example network,
the physical LAN consists of a switch, two servers, and five clients. The LAN is
logically organized into three different VLANs, each representing a different IP
subnet. Table 3-1 describes the features of this network.
