Virtual LANs

Figure 3-2: Multiple VLANs
FORMULA 8200 VLANs are port-based. A port cannot be part of more
than one VLAN. That is, if your FORMULA 8200 is configured for 8
ports, the switch can support up to 8 VLANs; if your switch includes
an 8-port expansion module, it supports up to 16 VLANs.
Use the VLAN/SHOW/VPORT command to see the virtual port
information. Refer to Chapter 5 for details on the command.
Each VLAN represents one IP subnet. Unlike a traditional router,
where each interface represents a different subnet, FORMULA 8200
VLAN switching allows multiple interfaces to share an IP subnet. If
you move an end station from one LAN segment to another within
the same VLAN, whether it is a local segment or a remote one, there
is no need to reconfigure its IP address.
