Scope
This document describes how to measure Metro Ethernet performance with the T-BERD 5800v2 or T-
BERD 5800-100G in accordance with Viavi’s Enhanced RFC 2544 test methodology. RFC-2544 is a
recommended test suite for verifying key performance indicators (KPIs) including Throughput, Delay and
Frame Loss. Viavi’s Enhanced RFC 2544 Test Suite also measures Jitter and Committed Burst Size (CBS)
to verify conformance to a Service Level Agreement (SLA) or Service Level Objectives. This document is
not intended to be a user guide. This Method of Procedure (MOP) should be used in conjunction with the
T-BERD User’s Guides for detailed explanation of all testing options.
The following procedures are documented:
Setting up the T-BERD up as a Layer 3 IPv4 Loopback device (Section 2)
Running a Layer 3 IPv4 RFC-2544 tests from the T-BERD (Section 3)
The Loopback device may be another Viavi test set (SmartClass, HST-3000 or T-BERD), a Viavi Test
Head (QT-600), a Viavi-compatible NID, or a Viavi JMEP loopable SFP.
Figure 1: T-BERD to Viavi compatible loopback device
The following minimum software revision is recommended:
T-BERD 5800-100G BERT Software Release 25.0
T-BERD 5800v2 BERT Software Release 25.1
If your T-BERD is Strata Sync enabled, use StrataSync to update your software. Otherwise, go to
http://updatemyunit.net/ for software update instructions. StrataSync can also be used to create
configuration templates and download configuration files for this procedure.

1. Hardware Description
The T-BERD 5800 is a portable test tool for Ethernet testing. The product can also be optioned to support
T1, DS3, SONET, OTN, Fiber Channel, CPRI, and OBSAI. Test connections are made from the top of the
mainframe. Menu selections are made from the T-BERD’s color touch screen. . The T-BERD 5800v2
uses RJ-45 ports, labeled 10/100/1000 for copper testing (10/100/1000BASE-T) and SFP+ ports for optical
testing:
Figure 2: T-BERD 5800v2 Top View (dual port configuration)
The T-BERD 5800-100G uses the SFP+ port for both copper and optical testing. The RJ-45 10/100/1000
port is only used for dual port testing and requires option C5DUALPORT:

loopback device. Pass/Fail status for each test will be indicated by green
checkmark, , or red x, . Test for which no pass/fail threshold was
specified will have a blue checkmark, . The Frame Loss test will
always have a blue checkmark, because there is no pass/fail value. Detailed
