Tutorial 2: Mixed Mode VLAN configuration with QoS

This configuration is designed for dual-service network e.g. VoIP/HSIA or IPTV/HSIA. Each service is assigned an 802.1Q VLAN ID unique for that service. The VLAN tag is used to ensure privacy and QoS throughout the network; from the service provider backhaul to each WallPlate port. In the mT2 system; Port-based VLANs and Tag-based VLANs can be mixed to ensure full port-privacy.

This advantage of this configuration is that it allows the service provider to configure only 2 unique 802.1Q VLAN IDs, and still have guaranteed port-to-port privacy on all ports in the network.

This configuration can be done via the webUI or CLI. The CLI commands are used below.

In this network:

Low Value Service

oWallPlate port 1 is connected to a low value service such as HSIA (high speed Internet). All packets are 802.1Q tagged in the mT2 network and transmitted on the core network.

High Value Service

oWallPlate port 2 is connected to a high value service such as VoIP or IPTV. All packets are 802.1Q tagged in the mT2 network and transmitted on the core network. QoS is applied in the mT2 based on the 802.1P priority bit.

Privacy and QoS in this network:

Privacy enforced between high and low value services in the network by the use of two VLAN IDs

Privacy enforced between WallPlates by using the Port-based VLANs on the mT2 Switch

QoS critical priority applied to high value service

High value service packets are tagged with an 802.1P bit of 5

VLAN-Ids used in this tutorial:

100 Tag all low value service with this VLAN ID. This VLAN will transmit on the upstream network

200 Tag all high value service with this VLAN ID. This VLAN will transmit on the upstream network

Eth1 (member of multiple Port-based VLANs.

One for each DSL port)

Port 1 (in Port-based VLAN with Eth1)
