simple VLANs to provide more features and functionality within your
network.
Using 802.1Q Tagged
Connections and
802.1Q Learning
The example shown in Figure 36 shows a network that has endstations
that support IEEE 802.1Q and network devices that have 802.1Q learning
enabled. The 802.1Q functionality of each endstation informs the
network that it is to receive traffic for certain VLANs, and the network
devices automatically place the endstation in those VLANs. In addition,
the links between the network devices are automatically configured to
forward traffic that contains unknown 802.1Q tags.
