To transmit MiM traffic
1 If you haven't already done so, launch the Mac-in-Mac
terminate application for the circuit you are testing (see
"Launching an application" on page
2 Initialize the link (see
testing" on page
3 Configure the HST for your test (see
in-MAC tests" on page
4 Press the Home button to return to the Summary Results
screen.
5 Press the Action soft key again, and then select one of
the following:
– Start Traffic (if you configured a constant, bursty, or
flooded load).
– Start Ramp (if you configured a ramped traffic load).
The HST-3000 transmits traffic over the link.
Actions on the Main screen allow you to insert errors and
pause frames into the traffic stream. If you turn on a particular
error insertion rate, the error insertion continues even after
you restart a test or change the test configuration.
For detailed instructions, see
and "Inserting pause frames" on page
You can measure round trip delay and packet jitter by trans-
mitting traffic carrying an Acterna payload. Frames with an
Acterna payload provide time stamps, enabling the unit to
calculate the delay and jitter.
