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 link.
Inserting errors
You can use the HST-3000 to insert errors into layer 3 IP
traffic when you perform end-to-end and loopback tests. For
details on error insertion, see “Inserting errors” on page 81 in
Chapter 3 “Ethernet Testing”.
Inserting pause frames
You can use the HST-3000 to insert pause frames into layer 3
IP traffic when you perform end-to-end and loopback tests. If
you are testing 10/100/1G electrical Ethernet, your unit must
be configured for full duplex (FDX) traffic. For details on pause
frame insertion, see “Inserting pause frames” on page 83 in
Chapter 3 “Ethernet Testing”.
Loopback testing
Layer 3 IP loopback testing allows you to transmit IP 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”
