+# QoS-1.1: Ingress traffic classification Test 
+
+## Summary
+
+Validate Ingress traffic classification.
+
+## Procedure
+
+*   Configure DUT with ingress and egress routed interfaces.
+*   Configure QOS classifiers to match packets arriving on DUT ingress interface to corresponding forwarding class according to
+    classification table.
+*   Configure packet re-marking for configured classes according to the marking table.
+*   One-by-one send flows containing every TOS/TC/EXP value in the classification table.
+*   For every flow sent, verify match-packets counters on the DUT ingress interface
+*   verify packet markings on ATE ingress interface
+*   verify that no traffic drops in all flows
