display all floors #1

Hi, we are having an issue in which we need to count the packets which toward to the servers 172.13.0.0/16. So we enabled the ACL which display as below to match the traffic, but after a few minutes, the matching counts always keep 0 though there do really is traffic towards to these servers.

Appreciate for any suggestiones.

It’s normal, the matching counts of the ACL only increase when the packets are processed by the CPU. For those packets which don’t requires processing by the switch, the matching count wouldn’t increase though these traffic match the ACL rules, just as the picture below shows.

If you want to count the packets, you are kindly advised to enable the traffic policy statistics.
