+ - #####Test ID: LTD.Throughput.RFC2889.ForwardPressure
+ **Title**: RFC2889 Forward Pressure Test
+ **Prerequisite Test**: LTD.Throughput.RFC2889.ForwardingRate
+
+ **Priority**:
+
+ **Description**:
+
+ The aim of this test is to determine if the DUT transmits frames with an inter-frame gap that is less than 12 bytes. This test overloads the DUT and measures the output for forward pressure. Traffic should be transmitted to the DUT with an inter-frame gap of 11 bytes, this will overload the DUT by 1 byte per frame. The forwarding rate of the DUT should be measured.
+
+ **Expected Result**:
+ The forwarding rate should not exceed the maximum forwarding rate of the DUT collected by LTD.Throughput.RFC2889.ForwardingRate.
+
+ **Metrics collected**
+
+ The following are the metrics collected for this test:
+
+ - Forwarding rate of the DUT.
+
+ **Deployment scenario**:
+
+ - Physical → virtual switch → physical.
