VIAVI SolutionsQuick CardT-BERD /MTS-5800 Network TesterEthernet RFC 2544 Layer 3 TrafficThis document outlines how to configure and run an RFC 2544 Layer 3 Traffic Test for Metro EthernetService Activation. A second T-BERD/MTS 5800 or compatible loopback device should be used at thefar-end of the line under test for traffic loopback.Equipment Requirements: T-BERD/MTS-5800 equipped with thefollowing:o BERT software release V27.0 or greatero Ethernet test options: C510M1GE for 1 Gigabit or less C510GELAN for 10 Gigabit Ethernet C525GELAN for 25 Gigabit Ethernet C540GELAN for 40 Gigabit Ethernet C5100GELAN for 100 GigabitEtherneto SFP, QSFP, or CFP4 optical transceiverto match the line under test Patch Cords to match the T-BERD/MTSoptics and the line under test Fiber optic inspection microscope (VIAVIP5000i or FiberChek Probe)Fiber Optic Cleaning suppliesFigure 1: Equipment RequirementsThe following information is required to complete the test: Physical Interface (10/100/1000BASE-T, 1000BASE-LX, 10GBASE-LR, 100GBASE-LR4, etc.) Auto Negotiation settings of the port under test VLAN ID, if VLAN tagging is used IP Address Parameters (DHCP or Static, Source IP, Default Gateway, Subnet Mask, andDestination IP)Fiber Inspection Guidelines: All fiber end-faces must be clean and passan inspection test prior to connection. Use the VIAVI P5000i, FiberChek Probe, orSidewinder microscope to inspect both sidesof every connection being used (SFP Port,bulkhead connectors, patch cords, etc.)Figure 2: Inspect Before You Connect

VIAVI SolutionsConnect to Fiber Under Test (FUT):1. For copper 10/100/1000BASE-T interfacetesting with the T-BERD/MTS 5800v2,connect the Port 1 10/100/1000 RJ-45 jackto the port under test using CAT 5E orbetter cable.2. For copper 10/100/1000BASE-T interfacetesting with the T-BERD/MTS 5800-100G,insert a copper SFP into the Port 1SFP /SFP28 slot and connect to the portunder test using CAT 5E or better cable.3. For optical interfaces: Insert SFP, QSFP, or CFP4 compatiblewith your physical interface into thePort 1 slot on the top of the test set. Inspect and, if necessary, clean allfibers and bulkheads, as described onpage 1. Connect the SFP, QSFP, or CFP4 to theport under test using a Single Mode orMultimode jumper cable compatiblewith the interface under test.Figure 3: T-BERD 5800v2 Dual Port mainframeFigure 4: T-BERD 5800-100G mainframeLaunch Test:1. Press the Power buttonto turn on the test set and view the startup screen.2. Using the Select Test menu, Quick Launch menu, or Job Manager, launch an Ethernet, RFC 2544, L3Traffic, Terminate test on port 1 for the desired physical interface. For example:Ethernet 10/100/1000 RFC 2544 L3 Traffic P1 Terminate.Figure 5: Startup Screen

If you aretesting a VLAN, set Encapsulation to VLANand enter your VLAN ID.Figure 7: L2 Network Settings – Local2. Tap thebutton to display theRFC 2544 Test: L3 Networks Settings Local screen.3. Enter IP Parameters (Source IP Type,Source IP, Default Gateway, SubnetMask, and Destination IP). The TBERD/MTS will resolve the destination IPaddress using the Address ResolutionProtocol (ARP). Once resolved, thebutton becomes available andyou can use it to verify connectivity to thefar-end loopback device.Figure 8: L3 Network Settings: Local4.
