Default Traffic Classes

The configuration includes a default traffic class that the ASA uses in the default global policy called Default Inspection Traffic; it matches the default inspection traffic. This class, which is used in the default global policy, is a special shortcut to match the default ports for all inspections. When used in a policy, this class ensures that the correct inspection is applied to each packet, based on the destination port of the traffic. For example, when UDP traffic for port 69 reaches the ASA, then the ASA applies the TFTP inspection; when TCP traffic for port 21 arrives, then the ASA applies the FTP inspection. So in this case only, you can configure multiple inspections for the same class map. Normally, the ASA does not use the port number to determine which inspection to apply, thus giving you the flexibility to apply inspections to non-standard ports, for example.

Another class map that exists in the default configuration is called class-default, and it matches all traffic. You can use the class-default class if desired, rather than using the Any traffic class. In fact, some features are only available for class-default, such as QoS traffic shaping.

Task Flow for Configuring a Service Policy Rule

Configuring a service policy consists of adding one or more service policy rules per interface or for the global policy. For each rule, you identify the following elements:

Step 1 Identify the interface to which you want to apply the rule, or identify the global policy.

Step 2 Identify the traffic to which you want to apply actions. You can identify Layer 3 and 4 through traffic.

Step 3 Apply actions to the traffic class. You can apply multiple actions for each traffic class.

Adding a Service Policy Rule for Through Traffic

See the “Supported Features” section on page 1-1for more information. To add a service policy rule for through traffic, perform the following steps:

Step 1 Choose Configuration > Firewall > Service Policy Rules pane, and click Add.

The Add Service Policy Rule Wizard - Service Policy dialog box appears.
