Carrier Ethernet Demarcation Device

TYPICAL APPLICATIONSHARDWARE-BASED ETHERNET OAM

ETX-203AX is used as an Ethernet
demarcation device. ETX-203AX separates
the service provider network, the accessprovider network, and the customer
network, providing proactive service
monitoring and easy fault localization
throughout the entire network (seeFigure 1).

Featuring ultra fast, hardware-powered
processing, ETX-203AX performs service
OAM and PM measurements in line ratewith maximum precision, offering thefollowing powerful benefits:

FLEXIBLE TRAFFIC MAPPING
Traffic is mapped to the Ethernet flows
using very flexible classification criteria
based on incoming port (port-based
all-to-one bundling), VLAN ID, VLAN
priority, IP precedence, DSCP, Ethertype,
and IP/MAC source/destination address.
Classification is defined for both
VLAN-tagged as well as untagged traffic.
The device can be configured to forward
Layer-2 control frames (including othervendors’ L2CP frames, and with optional
MAC change) across the network per EVC,to peer-supported protocols(IEEE 802.3-2005 and LACP), or to discard
the L2CP frames
HIERARCHICAL QUALITY OF SERVICE(H-QOS)
Different service types require different
levels of QoS to be provided end-to-end.
QoS can be defined per subscriber as wellas per service. QoS has three aspects: rate
limitation, traffic shaping, and traffic
prioritization.

Immediate detection of loss ofcontinuity (LOC), ensuring under
50 ms protection switchingHighly accurate frame loss
measurements of live trafficFlow-level monitoring, simultaneously
processing multiple OAM sessions with
E-LAN and E-TREE supportNon-disruptive MAC and IP levelloopback for network integrity testing.

ETX-203AX provides these types of
Ethernet OAM:Single-segment (link) OAM according
to IEEE 802.3-2005 for remotemanagement and fault indication,including remote loopback, dying gasp
with SNMP trap, and MIB parameter
retrieval. Active and passive mode aresupported.

End-to-end connectivity OAM based onIEEE 802.1ag-D8 that enables Ethernet
service providers to monitor theirservices proactively and guarantee that
customers receive the contracted SLA

End-to-end service and performancemonitoring based on ITU-T Y.1731.
Fault monitoring and end-to-end
performance measurement include
delay, delay variation, frame loss andavailability.

FAULT PROPAGATIONThe unit provides a user-configurable fault
propagation mechanism in thenetwork-to-user or user-to-network
direction.
When a link failure is detected or OAM
failure received, ETX-203AX can shut
down the affected port or forward theOAM failure message. The fault
propagation mechanism enables routersand switches connected to both ends ofthe link to reroute the traffic to theredundancy path.

Traffic policing is applied per flow or groupof flows, and operates according to thedual token bucket mechanism based onuser-configurable CIR + CBS and EIR + EBS.
Traffic can be limited to the line rate or
the data rate.
Every flow per EVC or EVC.cos has its own
queues and scheduler supporting strictpriority and weighted fair queues (WFQ).
Queue blocks of eight queues per EVC arescheduled and shaped, forming an H-QoS
model with shaped services and prioritizedclasses of service. The queues use WRED
mechanism for smart packet drop.

Data Sheet

RFC-2544
The device provides a built-in RFC-2544
wirespeed traffic generator and analyzer
for unidirectional and bidirectional testingof throughput, latency, and frame loss.
Based on standard OAM messages, thetests can be simultaneously performed
over multiple flows, at the EVC.CoS level.
Enhanced RFC-2544 functionality provides
service-oriented KPI analysis. SLA
conformance is measured per service
bandwidth and packet size, within auser-defined amount of time, for faster
service introduction.

The performance of the hardware-based
Ethernet OAM together with protection
switching for physical layer failure ensures
fast protection in any scenario.
The flow level protection provides a fullset of manual commands for maintenancepurposes.
INTEGRATED SMART SFPIntegrated management of MiRICi smart
SFPs provides TDM (E1/T1/E3/T3/OC-3/STM-1) connectivity over PDH or
SDH legacy networks. ETX-203AX supports
configuration and statistic collection forthe smart SFP TDM port.

NETWORK INTERFACE RESILIENCYETX-203AX provides the following network
interface protection modes:Link aggregation (LAG) based on
802.3ad, providing 1:1 link protection
with Link Aggregation Control Protocol(LACP) support
Dual homing (1:1), allowing ETX-203AX
units to be connected to two different
upstream devices.

FLOW LEVEL RESILIENCYETX-203AX applies standard ITU-T G.8031
Ethernet linear protection switching forfast protection of one or more EVCs fromend to end basis. With standard APS
functionality, Ethernet OAM messages
provide bandwidth-efficient unidirectionalor bidirectional 1:1 protection.
The EVC protection path can be configured
as follows:On same network port as the active
path – Protection is applied on thetransport network by transmitting theworking and protection traffic on
separate paths.
Separate from the working path – Theuser benefits from protection for link
and network failure and can alsoachieve load balancing on network
interfaces by splitting traffic between
two ports.

COLOR-AWARE P-BIT RE-MARKINGThe VLAN priority bit in Ethernet frames
can be modified at network ingress
according to the ‘color’ of the frame. This
allows service consistency and QoS
continuity across color-aware (DropEligible-enabled) as well as color-unawarenetworks.
DYING GASPETX-203AX reports power failures todefined network management stations bysending an IEEE 802.3-2005 message orSNMP trap, thus enabling the unit toproperly disconnect from the networkwith notification of the reason for theservice problem.
LAYER-2/ LAYER-3 LOOPBACK WITH
MAC AND IP ADDRESS SWAPPING
Layer-2 and/or layer-3 network integrity
can be tested by a non-disruptive
loopback performed per flow, withswapping of MAC address and optionallyIP address. When the loopback isactivated, ETX-203AX exchanges thesource and destination MAC/IP addressesof the incoming packets. This loopback
passes through Ethernet bridges(MAC address) and routers (IP address).

SECURITY
The following security protocols areprovided by ETX-203AX to ensure clientserver communication privacy and correctuser authentication:
SNMPv3



RADIUS (client authentication)

TACACS+ (client authentication,authorization, and accounting)SSH (secure shell communicationsession).

SFTP (secure file transfer).

TRAP SYNCHRONIZATION
Traps are sent with sequence IDs tonetwork manager groups, to enable themanagers to detect when traps are lostand request the traps be sent again.
ZERO TOUCH PROVISIONING
IP address, IP mask, default gateway, andlink to configuration manager can beautomatically obtained using standard
DHCP client functionality. This enablesseamless node setup and configuration
for quick and scalable network setup anddeployment as well as configurationconsistency when nodes must bereplaced.
MANAGEMENTThe unit can be managed using thefollowing ports and applications:Local management via an ASCII
terminal connected to the RS-232 portOut-of-band management via a
dedicated management port

Remote inband management via useror network ports routed via separate
VLANs, Telnet, or an SNMP-based
management system.

COMMAND LINE INTERFACE
Databases and scripts of commonly usedcommands can be easily created andapplied to multiple units using commandline interface.
