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”
