Figure 2 Troubleshooting an ACL application failure

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.
− If they are configured incorrectly, reconfigure them.
− If they are configured correctly, go to step 2.
2. Verify that the ACL is configured correctly.
