a. Use the following commands to display ACLs that are used by QoS policies and packet
filters:
− display packet-filter
− display qos policy user-defined
− display traffic classifier user-defined
b. Execute the display acl command to check for overlapping rules in the ACLs.
For example, the following sample output shows that rule 0 in ACL 3100 and rule 0 in ACL
3009 can both match traffic sourced from 2.2.2.1.
ACL number 3100
rule 0 permit ip source 2.2.2.2 0.0.255.255
ACL number 3009
rule 0 permit ip source 2.2.2.2 0.0.0.255
2. Check the filters and policies that use overlapping ACLs for a behavior conflict.
If two behaviors conflict, the device performs the behavior that has higher priority, as shown
in Table
Table 4 Rules for selecting a higher priority behavior from conflicting behaviors
Conflicting behaviors
•
redirect
•
filter permit
•
redirect
•
filter deny
•
filter permit
•
filter deny
3. Revise ACLs, packet filters, or QoS policies to remove the behavior conflict.
4. If the problem persists, contact Hewlett Packard Enterprise Support.
