Figure 5 Troubleshooting an ACL application failure 
 
 
Solution 
To resolve the issue: 
1.  Execute the display qos-acl resource command, and then check the Remaining field for 
ACL resources insufficiency. 
If this field displays 0, the ACL hardware resources are exhausted. 
2.  To free hardware resources, delete unnecessary ACLs. 
3.  If the issue persists, contact H3C Support. 
ACL application failure without an error message 
Symptom 
The system applies a packet filter or an ACL-based QoS policy to the hardware. However, the ACL 
does not take effect.
