IEEE 802.1Q VLAN Workgroups
BayStack 350 switches support up to 64 port-based VLANs with 802.1Q tagging 
available per port. Ports are grouped into broadcast domains by assigning them to 
the same VLAN. Frames received in one VLAN can only be forwarded within 
that VLAN, and IP Multicast frames and unknown unicast frames are flooded 
only to ports in the same VLAN.
Setting up virtual LANs (VLANs) is a way to segment networks to increase 
network capacity and performance without changing the physical network 
topology (Figure 1-8
). With network segmentation, each switch port connects to a 
segment that is a single broadcast domain. When a switch port is configured to be 
a member of a VLAN, it is added to a group of ports (workgroup) that belong to 
one broadcast domain.
BayStack 350 switches allow you to assign ports to VLANs using the console or 
TELNET; VLAN assignment is not currently available through SNMP. You can 
assign different ports (and therefore the devices attached to these ports) to 
different broadcast domains. This feature allows network flexibility because you 
can reassign VLANs to accommodate network moves, additions, and changes, 
eliminating the need to change physical cabling.
