Ramp mode is a feature that is commonly used to simulate a dynamic increasing and
decreasing traffic load on a network device. This is normally performed to monitor a
network device's performance, under these varying loads. This mode can also be used
as a stress test, when the traffic increase is set to a very steep rate change.
Configuration Settings (from the
•
Rate: From this menu select either Ramp %Bandwidth or Ramp Mbit/sec.
Next, enter either the maximum % Bandwidth or Mbps rate that you want the
stream traffic to step up to.
•
Ramp Step: This is the size of the % Bandwidth or Mbps rate that each step (up
and down) should change by.
•
Ramp Floor: This is the minimum % Bandwidth or Mbps rate that the stream will
step down to.
•
Ramp Duration: This is the number of Seconds (1 to 999) that each step (up
and down) will transmit for.
Setup:
1. Turn OFF the test streams, and press the Restart button to clear any packet
count history.
2. Next turn ON the test Stream(s) that are configured for Ramp Mode.
3. Monitor the network device under test (DUT) for anomalies, as the traffic being
generated repeatedly steps up and steps back down again, increasing and
decreasing its RX traffic load.
4. Turn OFF the test Stream(s), and verify that the DUT's RX Packet count and the
TX Packet count match.
