  • Have you made sure that the denied traffic is running through VLAN 13? Have you tried applying the ACL to the interface facing the WAP?

  • Yes, I am applying the acl to int vlan 13 as shown and have also specified the exact subnet for this vlan in the acl.

  • When you run the ping does the number of matches in "permit ip any any" increase? If not, then this ACL doesn't apply to this traffic

I can confirm that the ACL is functioning as expected. Initially, I attempted to ping from the IP address of the Interface VLAN 13 (the gatway of this vlan 13) which means the ping was generated directly from the multilayer switch. However, I realized that the ACL's purpose is to filter traffic that passes through it, not the traffic generated by the device itself. This explains why the pings were not affected by the ACL. Thank you for your help and support.
