1.3. Function Description
Built-in tasks in APMPT-4 include Unicast, Flow Control, Broadcast, Filter, CRC Error, Ping, PoE, Power,
Console port tasks and other tasks.
1.3.1. Performance Task in Layer 1 (PT1)
DUT OSC Test
Test the speed rate of the DUT
By using this utility, operator is able to measure oscillator's speed of DUT that is either faster or slower
than standard speed in ppm scale, or use it as criteria to judge the result of test.
1.3.2. Performance Task in Layer 2 (PT2)
A. Unicast Test
Unicast transmission is to send information packets to a single destination. In layer 2 test, unique MAC
address is the key of single destination as illustration below.
Perform unicast test on DUT in layer2 with different speeds, modes and various configurations.
PT2-UC-10H (10Mbps Half Duplex),
PT2-UC-10F (10Mbps Full Duplex),
PT2-UC-100H (100Mbps Half Duplex),
PT2-UC-100F (10Mbps Full Duplex),
PT2-UC-1G (1Gbps Full Duplex),
PT2-UC-10G (10G Full Duplex),
PT2-UC-GROUPS (Perform Layer 2 MAC address Unicast performance test by two groups
settings with different media types such as 100Mbps and 1Gbps for DUT ports with different
maximum speeds)
