QoS-1.1 - Validate Ingress traffic classification

[charantejag504]

QoS-1.1 - Validate Ingress traffic classification.

• 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 ( Introduced a new deviation MatchedPacketsOctetsUnsupported as this is not supported by some vendors)
• Verify that no traffic drops in all flows.
