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
o
WallPlate 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
o
WallPlate 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
