Configuring the Service Type and Optional Parameters for a PVC

Configuring the Service Type and Optional Parameters for a PVC

If PVC/PVP traffic planning is required, you can configure the service type and overload bandwidth for PVCs/PVPs.

Before You Start

Before configuring the service type and optional parameters for a PVC, familiarize yourself with the applicable environment, complete the pre-configuration task, and obtain the required data. This can help you complete the configuration task quickly and accurately.

Usage Scenario

You can configure the service type and parameters for a PVC during PVC traffic planning.

Pre-configuration Tasks

Before configuring the service type or optional parameters for a PVC, complete the following tasks:

  • Configure physical attributes for the Router ATM interface.

  • Configure an IP address and mask for the ATM interface or sub-interface.

  • Create a PVC and configure the application mode.

Data Preparation

To configure the service type for a PVC, you need the following data.

No.

Data

1

Number of the ATM interface or sub-interface

2

IP address and mask of the ATM interface or sub-interface

3

PVC name and VPI/VCI value

4

CBR: PCR and CDVT

5

NRT-VBR: PCR, SCR, MBS, and CDVT

6

RT-VBR: PCR, SCR, MBS, and CDVT

7

(Optional) Overload bandwidth of the ATM interface

Configuring a Service Type for a PVC

PVC services are classified as CBR, NRT-VBR, RT-VBR, UBR, or UBR-plus.

Context

To configure a service type for a PVC, you must create a service type in the system view and apply the service type to the PVC.

Perform the following steps on the Router:

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run atm service service-name { cbr output-pcr cdvt-value | nrt-vbr output-pcr output-scr output-mbs cdvt-value | rt-vbr output-pcr output-scr output-mbs cdvt-value | ubr output-pcr [ cdvt-value ] | ubr-plus output-pcr output-mcr cdvt-value }

    A service type template is created, and parameters are configured.

    By default, the service type of a PVC is UBR.

    The service type can be configured as CBR, NRT-VBR, UBR, UBR-plus, or RT-VBR.

  3. Run interface atm interface-number [ .subinterface ]

    The ATM interface or sub-interface view is displayed.

  4. Run atm cell transfer

    The ATM cell transport mode is configured.

  5. Run pvc [ pvc-name ] vpi/vci

    A PVC is created, and the PVC view is displayed.

  6. Run shutdown

    The PVC is shut down.

  7. Run service { output | input } service-name

    A service type template is configured for the PVC.

  8. Run undo shutdown

    The PVC is started.

Configuring a Service Type for a PVP

PVP services are classified as CBR, NRT-VBR, RT-VBR, UBR, or UBR-plus.

Context

To configure a service type for a PVP, you must create a service type in the system view and apply the service type to the PVP.

Perform the following steps on the Router:

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run atm service service-name { cbr output-pcr cdvt-value | nrt-vbr output-pcr output-scr output-mbs cdvt-value | rt-vbr output-pcr output-scr output-mbs cdvt-value | ubr output-pcr [ cdvt-value ] | ubr-plus output-pcr output-mcr cdvt-value }

    A service type template is created, and parameters are configured.

    By default, the service type of a PVP is UBR.

    The service type can be configured as CBR, NRT-VBR, UBR, UBR-plus, or RT-VBR.

  3. Run interface atm interface-number.subinterface

    The ATM sub-interface view is displayed.

  4. Run atm cell transfer

    The ATM cell transport mode is configured.

  5. Run pvp vpi

    A PVP is created, and the PVP view is displayed.

    A PVP can be configured only on an ATM sub-interface.

  6. Run shutdown

    The PVP is shut down.

  7. Run service { output | input } service-name

    A service type template is configured for the PVP.

  8. Run undo shutdown

    The PVP is started.

(Optional) Configuring the Overload Bandwidth for an ATM Interface

The overhead bandwidth of an ATM interface refers to the sum of committed bandwidth of all PVCs and PVPs on the interface.

Context

Perform the following steps on the Router:

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface atm interface-number

    The ATM interface view is displayed.

  3. Run service bandwidth-overload overload-value

    The overload bandwidth is configured for an ATM interface.

    You can run the service bandwidth-overload command to set the overload bandwidth of the PVCs and PVPs of all services on the ATM interface.

    By default, the overload bandwidth of the ATM interface is 0 kbit/s.

Verifying the Configuration

After the service type and optional parameters of a PVC are configured, you can check the configuration of the service type template and the statistics.

Procedure

  • Run the display interface atm [ interface-number [.subinterface ] ] command to check the configuration and status of the ATM interface or sub-interface.
  • Run the display atm service [ service-name ] command to check the configuration of the service type template.
  • Run the display atm { pvc | pvp } statistics interface atm interface-number [ pvc vpi/vci | pvp vpi ] command to check PVC or PVP statistics.

    NOTE:

    The display interface atm command displays the statistics of all the packets discarded on an interface. The display atm pvc statistics command displays only the statistics about the packets dropped on the PVC or PVP due to traffic congestion. Therefore, run the commands as required.

Example

Run the display interface atm command. The command output shows the ATM interface configuration and interface status.
