Destination Command
Interface

VLAN
display qos vlan-policy

display qos policy global
b.
If the QoS policy does not contain a class-behavior association, associate the traffic

c.
If the QoS policy contains a class-behavior association, execute the

command and the
display traffic behavior user-defined
command to check for traffic class and behavior configuration errors, respectively.
