Configuring a DPI Network Element

To configure deep packet inspection (DPI) network element:
  1. From the Network section of the navigation pane, select Network Elements.

    The content tree displays a list of network element groups; the initial group is ALL.

  2. From the content tree, select a network element with a type of DPI.

    Note: If the list does not contain an element with the appropriate type, you must first define the network element of that type. See Creating a Network Element.

    The Network Element Administration page opens in the work area.

  3. On the Network Element Administration page, select the DPI tab and then click Modify.

    The Modify Network Element page opens.

  4. Configure the following information:
    1. IP Domain ID—This field is reserved for future use.
    2. Diameter Realm—Specifies the domain of responsibility for the network element (for example, example.com).
    3. Diameter Identity— Specifies the fully qualified domain name (FQDN) of the network element (for example, ne.example.com).

      Note: A vendor-specified host name and realm name (such as ne.example.com) resolves to an internal DNS server for vendor network access only. For Internet (roaming) access, use the format defined in the 3GPP Technical Specification: host name, network code, country code, and domain name.

      A single network element can have multiple Diameter identities with each represented as a separate Diameter connection from the same appliance. Click Add to add the identity to the list. To delete one of the identities, select it form the list and click Delete.

  5. (TDF-Solicit fields) Configure the following traffic detection function fields.

    Note: Traffic detection function fields are only available when the network capacity is TDF-Solicit. See Creating a Network Element for more information.

    1. SCTP Enabled (available if DPI capability is TDF-Solicit)—By selecting the check box, you connect to the traffic detection function (TDF) using the SCTP protocol. TCP is the default connection protocol.
    2. Allow direct connection from MPE (available if DPI capability is TDF-Solicit)—By selecting the check box, TDF connects directly to Sd with the MPE device (bypassing the MRA device).
    3. TDF Port (available if DPI capability is TDF-Solicit)—Enter the port number used to communicate with the TDF device. The default port is 3868.
    4. Watch Dog Interval (available if DPI capability is TDF-Solicit)—Enter the watchdog interval in seconds. The default is 6 seconds.
    5. Response Timeout (available if DPI capability is TDF-Solicit)—Enter the response timeout interval in seconds. The default is 5 seconds.
    6. Reconnect Delay (available if DPI capability is TDF-Solicit and Allow direct connection from MPE is selected)—Enter the response time in seconds. The default is 3 seconds.
    7. Associated MRA identity (available if DPI capability is TDF-Solicit)—Select the MRA device from the list.

      You cannot associate a DPI device with an MRA device if you have selected Allow direct connection from MPE.

    8. Backup TDF Identity (available if DPI capability is TDF-Solicit)—Select the backup TDF device from the list.
  6. Click Save.
The DPI device is configured.
