How Do I Check Statistics on Packets Matching ACL Rules When a Traffic Policy Containing ACL Rules and Redirection Is Applied to CloudEngine 12800 and 12800E Series Switches?

How Do I Check Statistics on Packets Matching ACL Rules When a Traffic Policy Containing ACL Rules and Redirection Is Applied to CloudEngine 12800 and 12800E Series Switches?

When ACL-based MQC and ACL-based simplified traffic policy are configured on CloudEngine 12800 and 12800E Series Switches, disable traffic statistics and then run the display acl hardware statistics command to check statistics on packets matching ACL rules.

The display acl all command cannot display statistics on packets that match ACL rules in MQC and the ACL-based simplified traffic policy.
<HUAWEI> display acl all
 Total nonempty ACL number is 1
 
Advanced ACL 3000, 1 rule
ACL's step is 5
 rule 5 permit ip dscp cs1 (0 times matched)
0 times matched indicates the number of times software ACL rules match services.
  • Packets of FTP, TFTP, Telnet, SNMP, HTTP, routing, and multicast are sent to the CPU and match software ACL rules. You can use the display acl all command to check the number of times packets match ACL rules.
  • When ACL-based MQC and ACL-based simplified traffic policy are configured on CloudEngine 12800 and 12800E series switches, packets are forwarded through the hardware and match hardware ACL rules. The display acl hardware statistics command is used to check statistics on packets matching hardware ACL rules. In addition, you must first use the statistics enable command in the traffic behavior view to enable traffic statistics and the traffic-statistics command in the interface, system, VLAN, or QoS group view to enable traffic statistics of simplified traffic policy.
