Chapter 11: Access Control Lists
126 Section II: Advanced Operations
To deny traffic from several subnets on the same port, you can create
multiple classifiers and apply them to the same ACL, as illustrated in the
next example. Three subnets are denied access to port 4. The three
classifiers defining the subnets are applied to the same ACL.
