1. INTRODUCTION
1.1 General
This document is valid as of Dragon PTN Release 3.0DR.
This document describes the 4-GO-LW interface module (=IFM) which provides four 1Gbps
LAN/WAN optical ports on the front panel (LAN = Local Area Network; WAN = Wide Area
Network). These optical ports are SFP based. Each individual port can be configured as either
LAN or WAN port via HiProvision (=Dragon PTN Management System). By default, each port
is configured as WAN port. 4-GO-LW refers to ‘4 ports – Gigabit Optical port – LAN WAN’.
The 4-GO-LW IFM can be used in the following IFM slots in the node:
IFM1,2,3,4,9 (1G/4*1G slots): Fully operational;
IFM5,6,7,8 (1G/10G slots): port1 = operational;port2,3,4 = not operational;
IFM10 (1G slot): port1,2,3 = operational; port4 = not operational;
IFM slot overviews for nodes can be found in the Dragon PTN Nodes manual Ref. [3] in
Table 1.
Main supported features:
Gigabit Ethernet Ports:
4 x SFP (Fiber, optical): 1000BASE-X / Smart SFP;
Synchronization
SyncE;
PTP IEEE 1588v2 (=Precision Time Protocol) (future support);
Smart SFP;
LAN or WAN function selectable per port;

2.1.2 LEDs
The meaning of the LEDs depends on the mode of operation (= boot or normal) in which the
4-GO-LW module currently is running. After plugging in the module or rebooting it, the
module turns into the boot operation, see Table 2. After the module has gone through all
the cycles in the table below (=rebooted successfully), the module turns into the normal
operation, see LEDs in Table 3.

2.1.3 Connectors
This module has following ports:
SFP: 100/1000 Gigabit Ethernet fiber port / Smart SFP; The SFPs that can be used for this
port can be found in Ref. [8] in Table 1;
2.2 Functional Operation
The 4-GO-LW performs following major tasks:
2.2.1 Media Module for Ethernet: Interfacing to a LAN or WAN Network
WAN ports interconnect nodes within the Dragon PTN network (MPLS-TP) whereas LAN
ports interconnect the nodes with their applications.
Each Ethernet front port can be configured individually as LAN or a WAN port in HiProvision.
By default, each port is configured as WAN port. A LAN port talks Ethernet and a WAN port
talks MPLS-TP. As a result, the node can serve as an edge node (or LER = Label Edge Router)
where traffic is received on a LAN port, mapped into pseudowire and forwarded to the
correct label switched path on a WAN port.
For a configured application service, the node can operate as a:
LER = Label Edge Router or access node: The node is located on the edge between the
LAN and WAN. The node converts Ethernet into MPLS-TP and vice versa;
LSR = Label Switching Router: The node is fully located in the WAN. The node has no end-
points for the configured application service, it only forwards MPLS-TP traffic via label
switched paths;

2.2.2 Ethernet Service
a. General
The 4-GO-LW IFM access or end-points communicate over the Dragon PTN network via an
Ethernet service. This service must be configured via HiProvision. This service can operate
port or VLAN based. An optional E-Tree can be configured as well on this Ethernet service.
b. Port Based / VLAN Based
Port based: Use this mode if all the traffic on a port must be transported transparently in
one and the same service;
VLAN based/VLAN ID: Use this mode if each VLAN (ID) on a port must have its own
service. Ethernet packets with the configured VLAN ID will be forwarded in this service,
other VLAN IDs and untagged packets will be dropped. This behavior can be overruled by
a more advanced VLAN processing in the ‘VLAN Tagging/Untagging’ feature in
HiProvision. This feature also supports VLAN translation which replaces VLAN ID ‘x’ into
VLAN ID ‘y’.
c. E-Tree
An E-Tree is a rooted (not routed) point-to-multipoint partial service within a programmed
Ethernet service. E-Tree can be used as a security precaution to separate different customers
(=leafs) using the same Ethernet service while accessing one or more ISPs (=roots).
When an E-Tree is used, each service endpoint is designated as either leaf or root. A leaf can
only communicate with a root. A root can communicate with all the roots and leafs.

2.2.3 Voice Service
The 4-GO-LW IFM ports can be configured in the Ethernet part of the Voice service. See Ref.
[1] and Ref.[7] in Table 1 for more information on the Voice service.
2.2.4 I/O with the Central Switching Module (=CSM)
The 4-GO-LW module receives traffic (Ethernet or MPLS-TP) via its front panel ports and
forwards this to the CSM via the backplane. The CSM does all the processing on this data
(synchronization, CRC checks, conversions, switching…). The resulting data will be
forwarded via the backplane to one of the IFMs in the node.
2.2.5 Synchronization / Clock Distribution / Network Timing
The Dragon PTN network provides a number of mechanisms to perform synchronization /
clock distribution / network timing. The CSM makes sure that all the included IFMs in the
node are synchronized. See the table below for an overview of the mechanisms that are
supported on the 4-GO-LW module.
It means that the front ports of the 4-GO-LW module can be used to recover a clock from an
incoming data stream and redistribute this clock via an outgoing datastream;

2.2.6 MPLS-TP Compliancy
See the CSM manual in Ref.[4].
2.2.7 Smart SFP
Smart SFP is a hot-pluggable optical transceiver that converts incoming STM/OC frames from
a fiber-optic SDH/SONET network into Ethernet frames at the 4-GO-LW front port 1 or vice
versa for outgoing frames. As a result, Dragon PTN allows to transparently transport
synchronous digital bit streams from an SDH/SONET network via the 4-GO-LW IFMs.
Smart SFPs must be used in a point-to-point port based Ethernet service over Dragon PTN.
The Smart SFP has an optional security feature onboard which allows to secure the point-topoint connection to only two dedicated MAC addresses. This can be done via setting the
Destination MAC Address in HiProvision for the Smart SFPs. Furthermore, the Smart SFPs
need some extra Quality of Service settings in HiProvision, see Ref. [1] in Table 1.
For clocking/Synchronisation, SyncE must be configured in the nodes that have Smart SFPs
plugged in.
Smart SFPs also generate appropriate alarms, e.g. Loss of Signal, Loss of Frame etc.
NOTE: Smart SFP is also called TSoP (Transparent Sonet/SDH over Packet).
NOTE: The supported Smart SFPs and speeds can be found in Ref. [8] in Table 1.
NOTE: SFPs are typically used on WAN ports whereas Smart SFPs are used on LAN ports.
Figure 4 SDH/SONET over Dragon PTN via Smart SFPs
2.2.8 Storm Control on Ethernet LAN Port
NOTE: Storm Control is not relevant/supported on WAN Ports;
A traffic storm is the growing of excessive network traffic due to Ethernet packets flooding
the LAN. Such a storm can for example occur because of a data loop in the network due to
no or misconfiguration of MSTP. These storms degrade the network performance and must
be avoided whenever possible.

The storm control feature:
is an extra protection against these traffic storms;
can be configured on the IFM ports;
limits the amount of unlearned received data (Unicast, Broadcast, Multicast) on the LAN
port ingress or input side;
limits the amount of transmitted data (all data) on the LAN port egress or output side;
Data that exceeds the configured limitations will be dropped. As a result, a possible data
storm cannot overload the node processor or the node will limit outgoing data.
See Ref. [1] in Table 1 for more configuration information in HiProvision.
2.2.9 BPDU Guard on Ethernet LAN Port
NOTE:
BPDU Guard is not relevant/supported on WAN Ports;
BPDU Guard (=Bridge Protocol Data Unit) is a LAN port property or feature that:
shuts down the LAN port when a BPDU packet enters this port;
sends out dummy BPDU packets.
As a result, this feature or IFM:
protects the network against possible loops created via this IFM, although this IFM does
not support MSTP;
protects a running MSTP protocol somewhere else in the Dragon PTN network from
external MSTP influences via this LAN port, e.g. root bridge protection etc...
See Ref. [1] in Table 1 for more configuration information in HiProvision.
