Section III: VLANs 435
The table below lists the port assignments for the Sales, Engineering,
and Production VLANs on the switches:
❑ Sales VLAN - This VLAN spans both switches. It has a VID value of
2 and consists of five untagged ports on the top switch and five
untagged ports on the bottom switch.
The two parts of the VLAN are connected by a direct link from port
8 on the top switch to port 7 on the bottom switch. This direct link
allows the two parts of the Sales VLAN to function as one logical
LAN segment.
Port 6 on the top switch connects to the router. This port allows
the Sales VLAN to exchange Ethernet frames with the other VLANs
and to access the WAN.
❑ Engineering VLAN - The workstations of this VLAN are connected
to ports 11-14 on the top switch and ports 14, 16, and 18-19 on the
bottom switch.
Because this VLAN spans multiple switches, it needs a direct
connection between its various parts to provide a
communications path. This is provided in the example with a
direct connection from port 20 on the top switch to port 19 on the
bottom switch.
This VLAN uses port 13 on the top switch as a connection to the
router and the WAN.
❑ Production VLAN - This is the final VLAN in the example. It has the
VLAN of 4 and its ports have been assigned the PVID also of 4.
The nodes of this VLAN are connected to only the top switch. So
this VLAN does not require a direct connection to the bottom
VLAN. However, it uses port 22 as a connection to the router.
