Overview

BER testing at Layer 1, 2, 3, and 4 is supported. The BERT can be configured to use either regular PRBS test patterns, stress patterns (specifically for 10Gigabit Ethernet) or user defined test patterns to simulate various conditions. The test layer, frame header, traffic profile, error injection, and control settings of the far-end device (if applicable) must be configured prior to testing.

 

• Layer 1: Unframed mode (fiber ports only) or Framed mode
  • Unframed mode: Test traffic consists of a bit stream of the selected test pattern
  • Framed mode: Test pattern is encapsulated into a valid Ethernet frame with SOF, Preamble, and CRC field

• Layer 2: Framed BERT (same as Layer 1 Framed)
  • MAC Address: A default or user configured Media Access Control (MAC) address is added to the frame

• Layer 3: Framed BERT (same as Layer 1 & 2 Framed)
  • MAC Address: A default or user configured Media Access Control (MAC) address is added to the frame
  • IP Address: A default or user configured IP address is added to the frame

• Layer 4: Framed BERT (same as Layer 1, 2, & 3 Framed)
  • MAC Address: A default or user configured Media Access Control (MAC) address is added to the frame
  • IP Address: A default or user configured IP address is added to the frame
  • UDP or TCP Address: A user defined source and destination port address is added to the frame
