Solution

Choose a solution depending on the module that uses the ACL.
ACL used in a QoS policy
To resolve the problem when the ACL is used in a QoS policy:
1. Verify that the QoS policy is configured correctly:
a. Use one of the following commands to check the QoS policy for configuration errors,
depending on the policy application destination:
Destination
Interface
VLAN
Global
Control plane
b. If the QoS policy does not contain a class-behavior association, associate the traffic behavior
with the traffic class.
c. If the QoS policy contains a class-behavior association, execute the display traffic classifier
user-defined command and the display traffic behavior user-defined command to check for
traffic class and behavior configuration errors, respectively.
