The maximum number of allowable virtual LANs in a single BayStack
28115/ADV switch is limited to 18 (one virtual LAN dedicated to each
attachment port and to each expansion port). A configuration of this type
typically serves no purpose because a port that is the only port in its virtual
LAN cannot pass frames to any other port. To take advantage of switching
requires at least two ports in each virtual LAN. Bay Networks therefore
recommends that you distribute virtual LANs logically across multiple
switches in your network as shown in

The real power of the BayStack 281xx switch emerges when you interconnect
switches together and implement multiple virtual LANs across multiple
switched ports.
