IES-5000/5005/6000 Support Notes

Configuring 802.1Q VLAN

A VLAN (Virtual Area Network) allows a physical network to be partitioned into multiple logical networks. Stations on a logical network belong to one group called VLAN group. A station can belong to more than one group. The stations on the same VLAN group can communicate with each other. With VLAN, a station cannot directly talk to or hear from stations that are not in the same VLAN groups.

In this application, we will show you how to configure an 802.1q VLAN. The following figure shows a VLAN network example where two computers (PC1 and PC2) are connected to ports 1 and 2 on the line card. Each computer belongs to a different VLAN (VLANs 10 and 20). Therefore the computers cannot communicate directly to each other. However, PC1 and PC2 still need connection to the Internet.

Setting up a VLAN

For this application, we will use an IES-5000 and Prestige ADSL 660R-61 CPE (any DSL CPE or P791 if you have the SLC-1248G line card installed on the IES). Since the two ports belonging to different VLANs need Internet access via the Uplink port
