This section contains examples of simple VLAN configurations. It
describes how to set up your switch to support simple untagged and
tagged connections.
The simplest VLAN operates in a small network using a single switch. In
this network there is no requirement to pass traffic for multiple VLANs
across a link. All traffic is handled by the single Switch and therefore
untagged connections can be used.
The example shown in
endstations and servers using untagged connections. Ports 1, 2 and 3 of
the Switch belong to VLAN 1, ports 10, 11 and 12 belong to VLAN 2.
VLANs 1 and 2 are completely separate and cannot communicate with
each other. This provides additional security for your network.

Create VLAN 2 on the Switch. VLAN 1 is the default VLAN and already
exists.
