<strong>Ethernet</strong> <strong>Switching</strong> Theory of Operation<br />
<strong>Ethernet</strong> <strong>Switching</strong><br />
Example<br />
Figure 3 shows a typical example of <strong>Ethernet</strong> switching. Port 24 is a member of both<br />
VLAN-1 and VLAN-2. Port 25 is a member of VLAN-1 and of VLAN-2. Because<br />
Station A and Station C are members of VLAN-1, they are able to transmit and<br />
receive MAC frames between each other, through the 3480 <strong>Ethernet</strong> Switch. Station<br />
B and Station D are members of VLAN-2, so they are able to transmit and receive<br />
MAC frames through the 3480 <strong>Ethernet</strong> Switch.<br />

Note<br />
Port 23 does not support switching, and in this example, port 27 is configured to<br />
support routing only. See <strong>Vanguard</strong> Applications Ware IP and LAN Feature<br />
Protocols <strong>Ethernet</strong> Basics Guide (Part No. T0109) for a detailed description of<br />
the Switch Capabilities Parameter.<br />
Note<br />
<strong>Ethernet</strong> Bridging is not supported on the VN3480 platform. The <strong>Ethernet</strong><br />
Bridging feature is replaced with the <strong>Ethernet</strong> <strong>Switching</strong> feature that is described<br />
in this manual.<br />
