12.7.1.1
VLAN Network Description
The network model is described as follows:
쎲
The PLC network is a switched network with different VLAN tags;
쎲
The firmware of all nodes is inside the Management VLAN and VLAN 1. PLC
management protocols (IFCP, BPC, etc.) use VLAN 1, while high-level
management protocols (DHCP, TFTP, HTTP, NTP, SNMP, etc.) use the
management VLAN configured by the autoconfiguration procedure. The
Management VLAN may be different in different LV cells;
쎲
The end user node receives untagged traffic from the external interface and
this traffic is tagged with the correct Data VLAN according to the ISP ope-
rator that the customer belongs to. So there can be more than one Data
VLAN per LV cell;
쎲
The end user node generates traffic from VoIP tagged with the correct VoIP
VLAN according to the voice operator that the customer belongs to. So there
can be more than one VoIP VLAN per LV cell;
쎲
It is possible to add private VLANs between specific customers that do not
belong to any ISP or voice operator. In this case, VLAN trunks must be defi-
ned in the intermediary equipment in order to allow all of that tagged traffic;
쎲
All of the traffic is tagged inside the PLC network
.
Each Wisconsin node must receive its VLAN configuration inside the autoconfi-
guration file. In addition to this, and in order to reduce the number of autocon-
figuration files for end user (EU) nodes (the highest number), there will be a
translation table transferred between nodes which contains information about
the Management, Data and VoIP VLANs used in a LV cell.
12.7.2
noVLAN Network
The use of VLANs is not mandatory but is advisable for privacy reasons. Never-
theless this privacy can be implemented with different tools or if the operator
simply wants to establish a LAN.
In this kind of network, a dLAN 200 DSpro adapter will not have the problems
associated with a VLAN network. It will perform its IFCP requests, switching bet-
ween VLAN #1 and not using VLAN, and finally a master will answer with the
translation table that will at least contain the parameter “USE VLAN”.
