Chapter 15: Access Control Lists
304 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 has been assigned one ACL, 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.
