Classification signatures define different types of traffic that the BIG-IP^® system can recognize through Traffic Intelligence. The system recognizes a predefined set of signatures for common applications and application categories that are updated periodically. You can download signature updates from F5 Networks, and schedule the system to automatically update the signatures (pull the updated signatures automatically). You can also manually install the classification signatures and updates, for example, if the BIG-IP system does not have Internet access.

2. Click Create.
3. In the Name field, type a 1- to 31-character name.
4. In the Definition field, type the syntax for the iRule using Tool Command Language (Tcl) syntax.
   For example, to classify traffic as xxx_app, a custom classification application that you created, you can use this iRule:

   when HTTP_REQUEST {
                           if { [HTTP::header "Host"] contains "xxx" }  {  
                           CLASSIFY::application set xxx_app 
                           }  
                           }  
                           } 
                       

   For example, to perform an action (in this case, drop) on traffic classified as xxx_app, you can use this iRule:

   when CLASSIFICATION_DETECTED {
                           if { [CLASSIFICATION::APP == "xxx_app"]}  {  
                           drop 
                           }  
                           } 
                       

   For complete and detailed information about iRules syntax, see the F5 Networks DevCentral web site http://devcentral.f5.com.
