To load a configuration
1 Press the Save soft key, and then select Load Config.
A list of saved configurations appears.
2 Select the configuration you want to load, and then press
OK.
The configuration is loaded.
Estimating throughput on the circuit
The instrument now automatically estimates the theoretical
throughput for each layer when you configure a constant load
of traffic for all single stream tests except Mac-in-Mac. This
estimate represents the throughput that you would hope to
attain given ideal circumstances on the circuit.
To estimate the ideal throughput on a circuit
1 If you haven’t already done so, launch your application
(see “Launching an application” on page 28 ), and then
select your 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
2 Press the Configure navigation key.
A configuration menu appears.
3 Use the left and right arrow keys to go to the Traffic
configuration menu.
4 Configure a constant load of traffic (see “Transmitting a
constant load” on page 57 ).
The instrument calculates the ideal throughput, and displays
it in a table under the settings.
