Guidelines
Here are the rules to creating ACLs:
A port can have multiple permit and deny ACLs.
An ACL must have at least one classifier.
An ACL can be assigned to more than one switch port.
An ACL filters ingress traffic, but not egress traffic.
The action of a ACL can be either permit or deny. A permit ACL
overrides a deny ACL on the same port when the ACLs define the
same traffic.
The order in which the ACLs are added to a port is not important since
the packets are compared against all of a port’s ACLs.
Since classifiers cannot be assigned more than once to a port, ACLs
that have the same classifier cannot be assigned to the same port.
An ACL and a Quality of Service policy cannot be assigned to the
same port if they have a common classifier.
The switch can store up to 64 ACLs.
