Configuring VLANs
Adding Virtual LAN (VLAN) support to a Layer 2 switch offers some of the benefits of both bridging and
routing. Like a bridge, a VLAN switch forwards traffic based on the Layer 2 header, which is fast, and like
a router, it partitions the network into logical segments, which provides better administration, security
and management of multicast traffic.
A VLAN is a set of end stations and the switch ports that connect them. You may have many reasons for
the logical division, such as department or project membership. The only physical requirement is that
the end station and the port to which it is connected both belong to the same VLAN.
