• Classification
works only in ingress direction. In Module QoS, policy-map can
only be applied in the ingress direction i.e. the interface on which the packets
are entering the DUT. Classification won’t work if the service-policy interface
is the egress interface.
• QoS not enabled on the interface. QoS must be enabled on the interface on
which the service-policy is mapped. Verify that QoS is enabled on the interface
using one of the following commands: show qos module ethernet
6/20 show qos module service-policy
