Impact on the System

The Layer 3 service specified in the alarm is unavailable.

Possible Causes

ACL resources were insufficient.


  1. Run the display acl resource [ slot slot ] command to view information about ACL resources, including ACL4 and ACL6 resources.
  2. Run the display current-configuration command to check the current configuration on the switch.
  3. Check the services that occupy ACL resources based on ACL resource information and the current configuration as follows, and delete unnecessary services to release ACL resources.

    • Check whether NAC, IPSG, MQC, and ACL-based simplified traffic policy services that occupy a large amount of ACL resources exist on the switch.
    • Check the services that occupy ACL resources based on fields in the ACL resource information. For example, MQC, ACL-based simplified traffic policy, SVF, MPLS, and BFD for VPLS services occupy UDF ACL resources. If a large amount of UDF ACL resources are occupied, check these services first.

  4. If the fault persists, collect log information and configuration information, and then collect log information and configuration information, and then contact technical support personnel. For details, see Troubleshooting-Information Collection-Collecting Diagnostic Information.
