70 CHAPTER 8: SETTING UP VIRTUAL LANS VLAN Configuration Examples This section contains examples of simple VLAN configurations. It describes how to set up your switch to support simple untagged and tagged connections. Using Untagged 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 Figure 20 illustrates a single Switch connected to 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. Figure 20 VLAN configuration example: Using untagged connections To set up the configuration shown in Figure 20: 1 Configure the VLANs Create VLAN 2 on the Switch. VLAN 1 is the default VLAN and already exists.

Examples
This section contains examples of simple VLAN configurations. It
describes how to set up your switch to support simple untagged and
tagged connections.
Using Untagged
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
Figure 20
illustrates a single Switch connected to
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.
