BIG-IP® Local Traffic ManagerTM includes a feature known as traffic classes. A traffic class is a feature that you can use when implementing optimization profiles for modules such as the WAN Optimization ModuleTM.
A traffic class allows you to classify traffic according to a set of criteria that you define, such as source and destination IP addresses. In creating the traffic class, you define not only classification criteria, but also a classification ID. Once you have defined the traffic class and assigned the class to a virtual server, the BIG-IP system associates the classification ID to each traffic flow. In this way, the BIG-IP system can regulate the flow of traffic based on that classification.
You configure a traffic class by using the BIG-IP Configuration utility to create the traffic class and assign the class to a virtual server.
Note: An alternate way to configure traffic classes is to use either the bigpipe utility or tmsh. For more information, see the Bigpipe Utility Reference Guide or the Traffic Management Shell (tmsh) Reference Guide.
Like most local traffic objects, traffic classes always reside in partitions. Therefore, before creating a traffic class, you should set the current administrative partition to the partition in which you want the traffic class to reside. This is either the partition containing the virtual server that will reference the traffic class, or partition Common.
For example, if the virtual server that is to reference the traffic class resides in partition A, then the traffic class you create can reside in either partition A or partition Common.
1.
On the Main tab of the navigation pane, expand Local Traffic, and click Traffic Class.
The Traffic Class screen opens.
3.
Configure all settings as needed.
For information on settings, see Configuring traffic class settings, or see the online help.
4.
Click Finished.
Table 16.1 describes the settings that you can configure for a traffic class.
Specifies a unique name for the traffic class. Traffic class names are case-sensitive and may contain letters, numbers, and underscores (_) only. Reserved keywords are not allowed. This setting is required.
Specifies a source IP address that the system should use to identify traffic belonging to this class. Any traffic originating from this IP address could be subject to the defined rate class.
Specifies a port name or number that the system should use to identify traffic belonging to this class. Any traffic originating from this port could be subject to the defined rate class.
Specifies a destination IP address that the system should use to identify traffic belonging to this class. Any traffic destined for this IP address could be subject to the defined rate class.
Specifies a port name or number that the system should use to identify traffic belonging to this class. Any traffic destined this port could be subject to the defined rate class.
Specifies the IP protocol to be used as a criterion for classifying traffic. Possible values are TCP and UDP. For example, if you specify a value of TCP, traffic coming into the BIG-IP system over TCP could become a member of this class.
Once you have created a traffic class, you can list existing traffic classes, view or modify the settings of a traffic class, or delete a traffic class.
