Configuring Basic FR Functions on a DCE

Configuring Basic FR Functions on a DCE

Before deploying FR access links, configure basic FR functions on the DCE.


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The FR interface view is displayed.

  3. Run link-protocol fr [ ietf | nonstandard ]

    An FR encapsulation type is configured on the interface.

    By default, the FR encapsulation type is IETF on the interface.


    After the FR encapsulation type on an interface is changed, the system automatically deletes all the FR configurations on the interface. Therefore, you need to re-configure the interface.

  4. Run fr interface-type dce

    The FR interface type is set to DCE.

    By default, the FR interface type is DTE.
    After the FR interface type is changed, LMI parameters are deleted automatically.

  5. (Optional) Run fr lmi type { ansi | nonstandard | q933a }

    The LMI protocol type is set.

    By default, the LMI protocol type is Q.933a on an interface.

  6. (Optional) Configure basic parameters on the DCE.

    1. Run the fr lmi t392dce t392-value command to configure the period for which the DCE waits for a status enquiry message from the DTE.
    2. Run the fr lmi n392dce n392-value command to configure the N392 parameter on the DCE.
    3. Run the fr lmi n393dce n393-value command to configure the N393 parameter on the DCE.

  7. Run quit

    Exit from the interface view.

  8. Run interface interface-type interface-number.subnumber [ p2p ]

    The FR sub-interface view is displayed.

  9. Run ip address ip-address { mask | mask-length }

    An IP address is configured for the FR sub-interface.

  10. Run fr dlci dlci

    A DLCI is configured for the VC.

    • If the FR interface type is DCE or NNI, a DLCI must be configured for the VC.
    • If you want to change a configured DLCI, run the shutdown command to shut down the sub-interface or delete the original DLCI.

  11. Run commit

    The configuration is committed.
