Example 2: Port-based VLAN

If VLAN is enabled and configured, each node in the network that can communicate with each other directly is
in the same VLAN.

The switch supports both port-based VLAN and tag-based VLAN. They are different in practical deployment,
especially in physical location. Figures 3-4 and 3-5 show a port-based VLAN and Figure 3-6 shows an
attribute-based VLAN.

24-Port 10/100BASE-TX L2 Managed PoE Switch with 2 SFP Dual Media Ports

VLAN 1 VLAN 2 VLAN 3 VLAN 4

Figure 3-4. One switch connected to four VLANs in a port-based VLAN.

NOTES

The same VLAN members must be connected to the same switch.

VLAN members can’t access another VLAN’s members.

The switch manager must assign different names for each VLAN group at one switch.
