Configure general SFC settings

Before doing this task, make sure you have opened the SFC controller package.

You configure general settings on the Setup screen of the SFC controller. The BIG-IP system uses this information as part of configuring the lightweight SFC controller and all service nodes for the service function chain.

  1. Click Launch SFC Config Editor.

    The Setup screen of the SFC controller opens.

  2. In the VNI for SFC field, type a virtual network identifier (VNI), for example 100, for the overlay network that connects the SFFs.

    This value is used for the field key in the tunnel object that the BIG-IP system creates later.

  3. In the REST Trust Group field, type a unique name for the trust group.

    The SFC application creates REST-based trust relationships between all BIG-IP devices that are service nodes in the chain. By default, the SFC application assigns the default name __f5_sfc_config_app__ to the trust group

  4. In the Config Prefix field, type a unique prefix for all object names that the SFC application will automatically create on the BIG-IP devices that will become service nodes in the chain.

    By default, the SFC application will apply the prefix __f5_sfc_app__ to each object name that the SFC controller internally creates in the service chain.

  5. In the Administrative Partition field, type a unique name for the BIG-IP administrative partition that objects in the service chain are created in.

    By default, the SFC application creates objects in partition Common.

  6. In the Audit Interval field, specify the time interval, in seconds, that is available to the SFC controller for auditing the configuration of all classifiers and SFFs.

    If there is any difference between the SFC controller configuration and the configuration of the SFFs and classifiers, the system displays an error message. The allowed range is 0 to 86400. Setting the value to 0 disables the audit feature.
