This switch supports ACLs for ingress filtering only. However, you can
only bind one IP ACL to any port and one MAC ACL globally for
ingress filtering. In other words, only two ACLs can be bound to an
interface - Ingress IP ACL and Ingress MAC ACL.

The order in which active ACLs are checked is as follows:
1. User-defined rules in the Ingress MAC ACL for ingress ports.
2. User-defined rules in the Ingress IP ACL for ingress ports.
3. Explicit default rule (permit any any) in the ingress IP ACL for ingress

ports.

4. Explicit default rule (permit any any) in the ingress MAC ACL for

ingress ports.

5. If no explicit rule is matched, the implicit default is permit all.
