Explanation
The purpose of above commands is to redirect traffic that matches the ACL “redirect-acl” to the Cisco
FirePOWER (SFR) module in the inline (normal) mode. In this mode, after the undesired traffic is dropped and
any other actions that are applied by policy are performed, the traffic is returned to the ASA for further
processing and ultimate transmission.
The command “service-policy global_policy global” applies the policy to all of the interfaces.
