Configuring IFL-Based TDF Subscribers and Properties with a TDF Domain

You configure one or more IFL-based TDF subscribers and a set of properties for processing the traffic for those subscribers by configuring a TDF domain. You can create multiple TDF domains.

Before you begin to create a TDF domain for IFL-based subscribers, make sure that you have done the following tasks:

  • Configured the TDF interface (mif-) that the TDF domain uses.

  • Configured the interfaces that the TDF domain uses.

  • Configured a VRF routing instance that includes the TDF interface and the interfaces that the TDF domain uses.

  • Configured the PCEF profile that the TDF domain uses.

To configure a TDF domain for IFL-based subscribers, perform the following:

Configuring the TDF Domain Name and Type

To configure the TDF domain name and type:

  1. Specify a name for the TDF domain. The name can be from 1 through 50 characters long.

    For example:

  2. Configure the subscriber type for IFL-based subscribers.

Configuring IFL-Based Subscribers

To configure IFL-based subscribers:

  1. Configure the name for a subscriber.

    For example:

  2. Configure one or more interfaces for the subscriber.

    For example:

    You can assign only one IFL-based subscriber to an interface.

  3. Repeat Step 1 and Step 2 for each IFL-based subscriber you want to configure in the TDF domain.

Configuring Address Filtering

To restrict the traffic that undergoes TDF processing for the TDF domain by identifying source IP addresses for uplink traffic and destination IP addresses for downlink traffic:

Identify the network prefix of source and destination IP addresses for packets that do not undergo TDF processing. Specify inet for IPv4 prefixes and inet6 for IPv6 prefixes.

Configuring Subscriber Services and Policies

To configure the services and policies for IFL-based subscribers that belong to the TDF domain:

  1. Identify the TDF interface for the TDF domain.

    The TDF domain uses the service set that is applied to this TDF interface.

    Note:

    The TDF interface (mif) must have been previously configured at the [edit interfaces] hierarchy level.

  2. Identify the PCEF profile that the TDF domain uses to apply policies.
    Note:

    The PCEF profile must have been previously configured at the [unified-edge pcef] hierarchy level.

Configuring Session Controls

To configure the TDF session controls for subscribers that belong to the TDF domain:

  1. Configure the default TDF subscriber maximum bit rate (MBR) for uplink and downlink traffic.

    Uplink traffic originates from the subscriber towards the public data network (PDN), and downlink traffic comes from the PDN and is destined for the subscriber. The range is 0 through 6,144,000 Kbps.

  2. Configure the default TDF subscriber allowed burst size for uplink and downlink traffic.

    Uplink traffic originates from the subscriber towards the public data network (PDN), and downlink traffic comes from the PDN and is destined for the subscriber. The range is 1500 through 1,500,000,000 bytes.
