II. Data VLAN
In networking environment, VLANs can carry various types of network traffic. The most common
network traffic carried in a VLAN could be voice-based traffic, management traffic and data traffic.
In practice, it is common to separate voice and management traffic from data traffic such as files,
emails. Data traffic only carries user-generated traffic which is sometimes referred to a user VLAN
and usually untagged when received on the Managed Switch.
In the network diagram provided, it depicts a data VLAN network where PC1 wants to ping PC2 in
a remote network. Thus, it sends out untagged packets to the Managed Switch to be routed in
Carrier Ethernet. For this example, IEEE 802.1Q tagging mechanism can be used to forward data
from the Managed Switch to the destination PC.
