T-BERD
/MTS-5800 Network Tester
Ethernet 4x10GigE Layer 2 Traffic Loopback
This document outlines how to set the T-BERD/MTS 5800 up as a Layer 2 Traffic Loopback device
across a Link Aggregation Group (LAG) with up to 4 10GigE links.
Equipment Requirements:
• T-BERD/MTS-5800 equipped with the
following:
o BERT software release V29.1.1 or
greater
o Ethernet test options:
▪ C510GELAN for 10 Gigabit Ethernet
▪ C54x10GELAN for 40 Gigabit
Ethernet
o 40GBASE-SR4 or 4x10GBASE-LR4 QSFP+
optical transceiver to match the line
under test
• MPO to LC fanout Cable to match the
optical transceiver and line under test
(Single mode or Multimode Fiber)
• Fiber optic inspection microscope with
MPO and LC tips (VIAVI Sidewinder)
• Fiber Optic Cleaning supplies
The following information is required to complete the test:
• Type of hash (Layer 2/MAC Address or Layer 3/IP Address)
• Number of 10GigE LAN physical ports in the LAG
(2 for 20Gig service, 3 for 30Gig service, 4 for 40Gig service)
Fiber Inspection Guidelines:
• All fiber end-faces must be clean and pass
an inspection test prior to connection.
• Use the VIAVI Sidewinder microscope to
inspect both sides of every connection
being used (QSFP Port, Breakout Cable,
bulkhead connectors, etc.)
