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 Command
Interface
display qos policy interface
VLAN
display qos vlan-policy
Global
display qos policy global
Control plane
display qos policy control-plane slot
slot-number
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.
