Section VI: Virtual LANs 595
The table below lists the port assignments for the Sales, Engineering, and
Production VLANs on the switches:
ˆ Sales VLAN - This VLAN spans both switches. It has a VID value of 2
and consists of six 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 4 on
the top switch to port 3 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.
ˆ Engineering VLAN - The workstations of this VLAN are connected to
ports 9 to 13 on the top switch and ports 16, 18 to 20, and 22 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
10 on the top switch to port 19 on the bottom switch.
This VLAN uses port 12 on the top switch as a connection to the router
and the WAN.
ˆ 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 only to the top switch. So this
VLAN does not require a direct connection to the bottom switch.
However, it uses port 20 as a connection to the router.
