Appendix C
Protocol VLAN Application Example
In order for an end station to send packets to different VLANs, itself has to be
either capable of tagging packets it sends with VLAN tags or attached to a
VLAN-aware bridge that is capable of classifying and tagging the packet with
different VLAN ID based on not only default PVID but also other information
about the packet, such as the protocol. The Protocol-based VLAN feature of the
switch can be applied for accommodating devices that you want to participate in
the VLAN by means of built-in knowledge of layer 2 packet formats used by
selected popular protocols, such as IP and Novell IPX. The following example
will demonstrate you how to configure the switch for protocol—based VLAN
application.
Figure 1 shows you two switches with workstations and servers which are going
to work by using protocol VLAN.

application, the IP frames from workstations will go to the IP server only and the
IPX frames will go to the IPX server only.
