VLAN Tutorials

Tutorial 3: Per port 802.1Q VLANs

This configuration is designed for a HSIA network where each port 1 on each WallPlate is assigned a unique VLAN.

In this network:

10.WallPlate port 1 is used for HSIA. WallPlate port 2 is disabled to prevent the subscriber from using the wrong port.

11.Eth1 on the switch is connected to an upstream network. Eth2 is disabled.

Privacy and QoS in this network:

12.Privacy enforced between all ports using 802.1Q VLANs

13.QoS is not used since there is a single service delivered to each user

VLAN-Ids used in this configuration:

14.101 - 2501 Assigned to port 1 of each WallPlate. The VLAN ID indicates the WallPlate and port number.

15.The chart shows a sampling of VLAN Ids to illustrate the naming convention in this tutorial.
