This test also determines whether or not the DUT will respond properly to two received frames separated by a minimum inter-frame gap. The DUT shall properly respond to valid frames separated by a minimum inter-frame gap.
Some devices respond to frames separated by a much smaller inter-frame gap.
The testing station is instructed to transmit a properly encapsulated, valid, 64-byte ICMP echo request frame. This will cause the DUT to transmit a 64-byte ICMP echo reply. The response of the DUT is observed. The response of the DUT is observed. Step 3 is repeated, reducing the inter-frame gap, until the DUT no longer responds properly to all frames.
