8 If you are inserting FCS, IP Checksum,
Layer 4 Checksum, or Acterna Payload errors, press the
Action soft key, 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).
You do not need to start traffic before inserting Code
Violations.
9 To insert the errors, press the Action soft key, and then
select the appropriate option for error insertion. For
example, if you configured the unit to insert a burst of FCS
errors, select Insert Burst FCS Error.
Errors are inserted into the traffic stream.
Inserting pause frames
You can use the HST-3000 to insert pause frames 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.
To insert pause frames
1 If you haven’t already done so, launch the Terminate
application for the circuit you are testing (see
), and then select a test (see
the appropriate procedure below):
–
“Selecting a layer 2 test” on page 46
–
“Selecting a layer 3 IP test” on page 120
–
“Selecting a layer 4 TCP/UDP test” on page 165
–
“Selecting a multiple streams test” on page 182
