+# DP-2.4 Police traffic on input matching all packets using 1 rate, 2 color marker
+
+## Summary
+
+Use the gRIBI applied ip entries from TE-18.1 gRIBI. 
+Configure an ingress scheduler to police traffic using a 1 rate, 2 color policer and attach the scheduler to the interface without a classifier.
+Lack of match conditions will cause all packets to be matched. 
+Send traffic to validate the policer.
+
+## Topology
+
+* [`featureprofiles/topologies/atedut_2.testbed`](https://github.com/openconfig/featureprofiles/blob/main/topologies/atedut_2.testbed)
+
+## Test setup
+
+Use TE-18.1 test environment setup.
+
+## Procedure
+
+### DP-2.4.1 Generate and push configuration
+
+* Generate config for 2 scheduler polices with an input rate limit.
+* Apply scheduler to DUT subinterface with vlan.
+* Use gnmi.Replace to push the config to the DUT.

+### DP-2.4.2 Test traffic
+
+* Send traffic
+  * Send flow A traffic from ATE port 1 to DUT for dest_A at 0.7Gbps (note cir is 1Gbps).
+  * Send flow B traffic from ATE port 1 to DUT for to dest_B at 1.5Gbps (note cir is 2Gbps).
+  * Validate qos counters per DUT.
+  * Validate qos counters by ATE port.
+  * Validate packets are received by ATE port 2.
+    * Validate DUT qos interface scheduler counters count packets as conforming-pkts and conforming-octets
+    * Validate at OTG that 0 packets are lost on flow A and flow B
+  * When the outer packet is IPv6, the flow-label should be inspected on the ATE.
+    * If the inner packet is IPv4, the outer IPv6 flow label should be computed based on the IPv4 5 tuple src,dst address and ports, plus protocol.
+    * If the inner packet is IPv6, the inner flow label should be copied to the outer packet.
+    * To validate the flow label, use the ATE to verify that the packets for 
+      * flow A all have the same flow label
+      * flow B have the same flow label
+      * flow A and B labels do not match
+  * Increase traffic on flow to dest_B to 2Gbps
+    * Validate that flow dest_B experiences ~50% packet loss (+/- 1%)
