88 Virtual LANs (VLANs) ELS100-24TXG
VLAN Application Example
A network administrator can u se VLA Ns to def ine user g roup s rega rdles s
of the physical LAN segment to which they are connected. The use of
Hybrid and Access links can further refine traffic flow in a multi-switch
environment. Figure D-4 shows the combination of both Hybrid and
Access links used in a network with three different VLANs. Workstations
are typically connected to the ELS100-24TXG via Access links. On the
internal corporate network (backbone ), VLAN tags are use d to identify the
VLAN association of frames.
Figure D-4. VLAN Application Example
It is possible to mix VLAN-aware and VLAN-unaware de-
vices on the same Hybrid switch port. However, this is not
recommended design practice.
