ETHERNET OVER FIBER

Hardware-based Ethernet OAM and

performance monitoring for SLA assurance

The device includes a complete Ethernet OAM

suite that supports Ethernet Link OAM (IEEE

standard 802.3-2005, formerly 802.3ah),

Ethernet Service OAM (IEEE 802.1ag) and

Performance Monitoring (ITU-T Y.1731). These

are enhanced with a built-in RFC-2544 test

generation engine, as well as Layer 1, 2 and 3

diagnostic loopback capabilities with MAC and IP

address swap.

Featuring ultra-fast, hardware-based processing

capabilities, the ETX-203A performs OAM and

PM measurements in under 1 microsecond with

maximum precision.

The device offers advanced SLA assurance tools,

including user-defined KPI (key performance

indicators) threshold configuration, real-time

SLA violation alerts and per-flow daily statistics

reporting.

Remote provisioning and traffic management

The ETX-203A allows efficient handling of multi-

priority traffic on a per-flow basis. It enables

multi-criteria traffic classification as well as

metering, policing and shaping to help carriers

rate-limit user traffic according to pre-defined

CIR (committed information rate) and EIR

(excess information rate) profiles.

Enhanced quality of service is further supported

by a hierarchical scheduling mechanism that

combines Strict Priority (SP) and weighted fair

queue (WFQ) scheduling, as well as weighted

random early detection (WRED) policy and color-

sensitive P-bit re-marking packet editing

functionalities.

Uplink resiliency and protection

The ETX-203A supports dual homing link

redundancy and Link Aggregation (LAG) using

802.3ad LACP. In addition, EVC path protection

is supported with Ethernet Linear Protection

Switching per ITU-T G.8031.

Management and security

The ETX-203A features flexible management

capabilities, including local management via an

ASCII terminal (RS-232). In addition, remote

management can be performed either inband

using the network or user ports, or out-of-band

using a dedicated management port, while

maintaining separation between management

and user traffic via the use of VLANs. Advanced

FCAPS (Fault, Configuration, Administration,

Performance, Security) and diagnostic tools are

provided by RADview-EMS, RAD’s carrier-class

element management system, via an SNMP-

based GUI.

The ETX-203A also supports a variety of access

protocols, including CLI over Telnet, SNMP, and

TFTP. Incorporated security features include

Secure Shell (SSH), Web-based Secure Socket

Layer (SSL), SNMPv3, RADIUS and Terminal

Access Controller Access-Control System

(TACACS+), as well as management access

control list (ACL).

The ETX-203A features a compact design and is

ideal for limited space installations.
