Chapter 14: Access Control Lists
254 Section II: Advanced Operations
ˆ A classifier can be assigned to multiple ACLs. However, a classifier
cannot be assigned more than once to a port. Put another way, ACLs
that have the same classifier cannot be assigned to the same port.
ˆ The switch can store up to 64 ACLs.
Examples
This section contains several examples of ACLs.
In this example, port 4 is assigned a deny ACL for the subnet 149.11.11.0.
This ACL prevents the port from accepting any traffic originating from that
subnet. Since this is the only ACL applied to the port, all other traffic is
accepted. As explained earlier, a port automatically accepts all packets
that do not meet the criteria of the classifiers assigned to its ACLs.
