Ethernet Network Interface Devices (E-NIDs) are commonly deployed at customer premises and managed via Management VLANs (MVLANs). The
implementation of E-NID MVLANs can be challenging due to the variety of technologies in a typical service provider network. It is useful to explore
strategies for managing E-NIDs with Fujitsu platforms.
Managing FLASHWAVE Platforms
The FLASHWAVE® 4100 ES, FLASHWAVE CDS and FLASHWAVE 9500 platforms are managed via TL1 commands from the NETSMART® 1500
Management System. Typically, the NETSMART 1500 is connected to the Local Communications Network (LCN) port of a FLASHWAVE 9500 as a
Gateway Network Element (GNE). The GNE forwards TL1 commands to the appropriate network element.
When SONET links connect the FLASHWAVE components, the Data Communications Channel (DCC) in the SONET overhead passes the TL1
commands. When OTN links connect the FLASHWAVE components, the General Communications Channel (GCC) in the OTN overhead passes the
TL1 commands. Figure 1 depicts these options.

When Ethernet links connect FLASHWAVE components, an MVLAN is created in band to pass TL1 commands from the NETSMART 1500 to each
FLASHWAVE network element (Figure 2).

Managing E-NIDs that Subtend a FLASHWAVE 9500 Platform
Typical deployment architectures use E-NIDs at the customer premises. This is shown in Figure 3, where green arrows indicate the customer trafc
path. These E-NIDs may be FLASHWAVE E-NIDs, say, multiple FLASHWAVE 9410 devices, or they may be third-party E-NIDs.

Figure 3: E-NIDs subtending a Fujitsu network
Most Ethernet E-NIDs use Simple Network Management Protocol (SNMP) via a management VLAN, not TL1, for provisioning. FLASHWAVE E-NIDs
may be managed via NETSMART 1500, while other E-NIDs must be managed via a separate E-NID management system. Both NETSMART 1500
and the separate E-NID management system connect to the Fujitsu solution via Ethernet connections through the Data Communications Network
(DCN). Unlike FLASHWAVE TL-1 management messages, which typically use DCC or GCC, E-NID SNMP management messages are in band with the
bearer trafc. But how do management messages for the E-NIDs ow through the Fujitsu transport system to the DCN and the management
system? That depends on how they are connected.
Fujitsu transport solutions use an Ethernet over Anything (EoX) Mapper in the FLASHWAVE 9500 for an Ethernet over SONET (EoS) aggregation
network, as shown in Figure 4. The E-NIDs typically take the customer trafc and encapsulate it using Generic Functional Protocol (GFP) into a
SONET frame. A SONET aggregation network then transports the SONET frames to the GNE. At the GNE—or one of the devices in the transport
network—an EoX Mapper extracts the Ethernet frames from the SONET payload and passes those frames to the DCN via an Ethernet facility.
Management frames use this same mechanism between the E-NIDs and the management system. Note that management messages for the
FLASHWAVE platforms use the out-of-band DCC or GCC channels, whereas management messages for the E-NIDs are carried in band.

Fujitsu transport solutions use Ethernet facilities in the FLASHWAVE 9500 for an all-Ethernet aggregation network, as shown in Figure 5. In this
case, the E-NIDs typically take the customer Ethernet trafc and send the Ethernet frames directly on the Ethernet connections. An Ethernet
aggregation network then transports the frames to the GNE and subsequently to the DCN. Management frames use this same mechanism
between the E-NIDs and the management system. Note that management messages for the FLASHWAVE platforms use the out-of-band DCC or
GCC channels, whereas management messages for the E-NIDs are carried in band in an MVLAN.

Managing E-NIDs that Subtend a FLASHWAVE 9500 with E-Line Services
With this understanding of the technology scenarios used to connect E-NIDs to the network, let’s explore how the devices are managed.
Direct Connect to FLASHWAVE 9500
Each E-NID connected to an E-Line–based FLASHWAVE 9500 Layer 2 network expects management frames on the same VLAN. The
FLASHWAVE9500 E-Line–based Layer 2 network needs a unique VLAN for each E-NID, however, and this requirement is met manually.
The NETSMART 1500 or third-party E-NID management system sends SNMP E-NID management messages into the DCN to the FLASHWAVE 9500
to the in-band management accessed via the MVLAN of the customer E-NID. The SNMP messages are IP routed in the DCN. But the
FLASHWAVE9500 Layer 2 network switches trafc by VLAN tags via E-Line services. The DCN router that sends packets from the NETSMART 1500 or
third party E-NID management system to the correct interface on the FLASHWAVE 9500 also adds the correct Customer VLAN (CVLAN) tag, and
these tags must be unique. This is not automatic; the service provider must manage it, plan it, and provision it.
The FLASHWAVE 9500 must be provisioned to translate the VLAN that each E-NID expects to a unique VLAN that the Layer 2 network can use to
direct the E-NID management system.
4
Upon receipt, the FLASHWAVE 9500 must translate the VLANs. Each E-NID expects management trafc on a specic VLAN, perhaps CVLAN 99. The
transport network switches these messages based on unique VLAN tags. At some point in the network, the transport network must translate the
unique VLAN tag to the expected VLAN tag. Figure 6 illustrates this with a FLASHWAVE 9500 and two E-NIDs, each of which expects management
trafc on CVLAN 99. But the FLASHWAVE 9500 network requires unique VLAN tags. The diagram shows untagged trafc from the OSS to the DCN
router, where a unique VLAN tag is pushed onto the frames—in this case, CVLAN 101 for the top E-NID and CVLAN 102 for the bottom E-NID. The
FLASHWAVE 9500 then uses the unique CVLANs to switch the messages to the correct E-NID and, in the process, translate the VLAN for each E-NID
to CVLAN 99.

Figure 6: Managing direct-connect E-NIDs with E-Line (single management port)
Bearer trafc and management trafc can use either the same port or different ports. Figure 7 illustrates direct-connected E-NIDs with a dedicated
management port. In this scenario, all management trafc uses specic ports, and bearer trafc uses other network ports. Regardless of the
number of ports, the functionality of the DCN router remains the same, and the need for MVLAN translation continues in the FLASHWAVE 9500.

Figure 7: Managing direct-connect E-NIDs with E-Line (dedicated management port)
Subtended FLASHWAVE CDS
To facilitate E-NID management, the FLASHWAVE CDS incorporates a small bridge. The PMVLAN command in the FLASHWAVE CDS can be used to
form an E-Tree for management. Instead of needing unique VLAN tags to manage each connected E-NID, the FLASHWAVE CDS requires just a
single unique VLAN tag. Figure 8 shows there is a single VLAN to each FLASHWAVE CDS for management of the connected E-NIDs.
As previously described, the DCN router is manually provisioned for unique management VLAN tags. But the FLASHWAVE 9500 does not need to
translate the management VLAN to each FLASHWAVE CDS. The translation function is performed in the bridge via the MVLAN feature on the
FLASHWAVE CDS.

Subtended FLASHWAVE 4100 ES
The need for complex, manual, and tedious VLAN management of E-NID management messages is not eliminated with a SONET Interofce
Facility (IOF), as shown in Figure 9. As per Figure 4, a SONET IOF uses EoS E-NIDs and a FLASHWAVE 4100 ES, or similar SONET platform, for SONET
aggregation, and an EoX Mapper in the FLASHWAVE 9500 to extract and aggregate the Ethernet trafc. Unique VLAN tags continue to be used in
the FLASHWAVE 9500 for switching added by the DCN router, and these VLANs still need to be translated to the management VLAN that the E-NID
expects.

How E-LAN Services in FLASHWAVE 9500 Improve E-NID Management
Direct Connect to FLASHWAVE 9500
An earlier release of the FLASHWAVE 9500 added support for bridging and E-LAN services. An E-LAN can be used to simplify the management of
E-NIDs. Everything is the same, except the E-LAN service switches management frames to the correct port.
The router in the DCN that routes packets from the NETSMART 1500 to the correct interface on the FLASHWAVE 9500 must add a unique
CVLAN tag. There is no need for the FLASHWAVE 9500 to translate the VLANs. There is no management of VLAN tags in the DCN router or the
FLASHWAVE9500.
6
This much simpler and more elegant method to managing E-NIDs is illustrated in Figure 10, where no unique VLANs are assigned. The DCN router
adds a single tag to the SNMP management messages. The E-LAN feature uses MAC addresses to forward SNMP messages to the correct E-NIDs.

Subtended FLASHWAVE CDS
Using an E-LAN is equally simple in a FLASHWAVE CDS Ethernet aggregation network. Everything is the same—the E-LAN service switches
management frames to the correct port based on the MAC address. As shown in Figure 11, no manual VLAN translation is required in the DCN
router, and no VLAN translation is required in the FLASHWAVE 9500. Note that the MVLAN command in the FLASHWAVE CDS is used to form an
E-Tree for management of multiple E-NIDs connected to a FLASHWAVE CDS.
Figure 11 also shows how the FLASHWAVE 9500 platform’s bridging function can automatically direct management frames to the correct NID
without manual VLAN manipulation. This function applies to Layer 2 E-Line and SONET aggregation networks.

Alarm Collection and Performance Monitoring
In addition to provisioning, comprehensive E-NID management also includes alarm and performance monitoring (PM) collection.
Although the NETSMART 1500 system manages FLASHWAVE platforms via TL1 commands, it can collect both SNMP and TL1 alarms and traps.
E-NIDs generate SNMP alarms that the NETSMART 1500 collects and displays.
While the NETSMART 1500 can collect instantaneous alarms and PMs, its history, database, and report generation capabilities are limited. It is
common for service providers to use a third-party PM collection system. The E-NIDs can send SNMP alarms and traps to multiple IP addresses. As
Figure 13 shows, a third-party PM collection system can be added to the network. As with management, the use of E-Line requires only manual
management of VLAN tags in the DCN router and the translation of those tags in the FLASHWAVE 9500. The use of an E-LAN in the
FLASHWAVE9500 greatly simplies PM collection, just as it simplies management.

Summary
E-NID management can be challenging and complex. Specically, with an E-Line–based Layer 2 FLASHWAVE 9500 network, MVLANs must be
manually selected, provisioned, translated, and tracked.
Fortunately, the E-LAN functions now available in the FLASHWAVE 9500 platform eliminate the need to manually select, provision, translate, and
track MVLANs. These more elegant E-NID management capabilities can signicantly reduce operational expenditures.
