Hello Ronald,
IOS-XE 17.9.x still supports Stateful CBAC firewall features, but the configuration has changed from using the "IP INSPECT" command set to using the "Zone-Based Policy Firewall" (ZBF) command set.
ZBF is a more advanced and flexible firewall technology than CBAC, and it allows you to define policies based on zones rather than IP addresses. ZBF also supports advanced features such as application-layer inspection and user-based policies.
