If a rule is simply appended, existing counters are not affected.

L2 ACL Behavior

If you configure an interface as a vlan-stack access port, only the L2 ACL filters the packets. The L3 ACL applied to such

a port does not affect traffic. That is, existing rules for other features (such as trace-list, policy-based routing [PBR], and QoS)

are applied to the permitted traffic.

For information about MAC ACLs, refer to

Assign an IP ACL to an Interface

To pass traffic through a configured IP ACL, assign that ACL to a physical interface, a port channel interface, or a VLAN.

The IP ACL is applied to all traffic entering a physical or port channel interface and the traffic is either forwarded or dropped depending on

the criteria and actions specified in the ACL.

The same ACL may be applied to different interfaces and that changes its functionality. For example, you can take ACL "ABCD" and apply it

using the in keyword and it becomes an ingress access list. If you apply the same ACL using the out keyword, it becomes an egress

access list. If you apply the same ACL to the Loopback interface, it becomes a Loopback access list.
