6 Press the Action soft key again, and then select
Start Traffic (if you configured a constant, bursty, or
flooded load), or Start Ramp (if you configured a ramped
traffic load).
The HST-3000 transmits traffic over the circuit.
Inserting errors
You can use the HST-3000 to insert errors (such as TCP/UDP
checksum errors) into layer 4 traffic when you perform end-to-
end and loopback tests. For details on error insertion, see
“Inserting errors” on page 81 of Chapter 3 “Ethernet Testing”.
Inserting pause frames
You can insert pause frames into the traffic stream when
transmitting layer 4 traffic. For details on pause frame inser-
tion, see “Inserting pause frames” on page 83 of
Chapter 3 “Ethernet Testing”.
Loopback testing
Loopback testing allows you to transmit traffic from one
HST-3000, and then loop the traffic back through a second
HST-3000 on the far end of a circuit. For details on loopback
testing, see “Loopback testing” on page 87 of
Chapter 3 “Ethernet Testing”.
