Example for Configuring ATM OAM

Example for Configuring ATM OAM

ATM OAM detects links in real time without interrupting services.

Networking Requirements

In Figure 12-3, RouterDevice A, Device B, and Device C are connected to the ATM network. IPoA services are configured on all the PVCs on ATM interfaces of the three Routers.

To implement real-time and continuous detection without interrupting services, configure the OAM CC function.

Figure 12-3 Configuring ATM OAM

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure IPoA services.

  2. Configure the OAM attributes of the connection point.

  3. Activate the CC function.

Data Preparation

To complete the configuration, you need the following data:

  • IP addresses of the ATM interfaces of the three Router

  • VPIs/VCIs of Device A connecting to Device B and Device C, respectively

  • VPIs/VCIs of Device B connecting to Device A and Device C, respectively

  • VPIs/VCIs of Device C connecting to Device A and Device B, respectively

Procedure

  1. Configure IPoA.

    # Configure Device A.

    <HUAWEI> system-view
    [HUAWEI] sysname DeviceA
    [DeviceA] interface atm 1/0/0
    [DeviceA-Atm1/0/0] ip address 202.38.160.1 255.255.255.0
    [DeviceA-Atm1/0/0] pvc to_b 0/40
    [DeviceA-atm-pvc-Atm1/0/0-0/40-to_b] map ip 202.38.160.2
    [DeviceA-atm-pvc-Atm1/0/0-0/40-to_b] quit
    [DeviceA-Atm1/0/0] pvc to_c 0/41
    [DeviceA-atm-pvc-Atm1/0/0-0/41-to_c] map ip 202.38.160.3
    [DeviceA-atm-pvc-Atm1/0/0-0/41-to_c] quit
    [DeviceA-Atm1/0/0] undo shutdown

    # Configure Device B.

    <HUAWEI> system-view
    [HUAWEI] sysname DeviceB
    [DeviceB] interface atm 1/0/0
    [DeviceB-Atm1/0/0] ip address 202.38.160.2 255.255.255.0
    [DeviceB-Atm1/0/0] pvc to_a 0/40
    [DeviceB-atm-pvc-Atm1/0/0-0/40-to_a] map ip 202.38.160.1
    [DeviceB-atm-pvc-Atm1/0/0-0/40-to_a] quit
    [DeviceB-Atm1/0/0] pvc to_c 0/42
    [DeviceB-atm-pvc-Atm1/0/0-0/42-to_c] map ip 202.38.160.3
    [DeviceB-atm-pvc-Atm1/0/0-0/42-to_c] quit
    [DeviceB-Atm1/0/0] undo shutdown

    # Configure Device C.

    <HUAWEI> system-view
    [HUAWEI] sysname DeviceC
    [DeviceC] interface atm 1/0/0
    [DeviceC-Atm1/0/0] ip address 202.38.160.3 255.255.255.0
    [DeviceC-Atm1/0/0] pvc to_a 0/41
    [DeviceC-atm-pvc-Atm1/0/0-0/41-to_a] map ip 202.38.160.1
    [DeviceC-atm-pvc-Atm1/0/0-0/41-to_a] quit
    [DeviceC-Atm1/0/0] pvc to_b 0/42
    [DeviceC-atm-pvc-Atm1/0/0-0/42-to_b] map ip 202.38.160.2
    [DeviceC-atm-pvc-Atm1/0/0-0/42-to_b] quit
    [DeviceC-Atm1/0/0] undo shutdown

  2. Configure the OAM attributes of the connection point.

    # Configure Device A.

    [DeviceA] interface atm 1/0/0
    [DeviceA-Atm1/0/0] oam
    [DeviceA-Atm1/0/0-fatm-oam] attribute 0/40 0/41 end-point

    # Configure Device B.

    [DeviceB] interface atm 1/0/0
    [DeviceB-Atm1/0/0] oam
    [DeviceB-Atm1/0/0-fatm-oam] attribute 0/40 end-point
    [DeviceB-Atm1/0/0-fatm-oam] attribute 0/42 end-point

    # Configure Device C.

    [DeviceC] interface atm 1/0/0
    [DeviceC-Atm1/0/0] oam
    [DeviceC-Atm1/0/0-fatm-oam] attribute 0/41 0/42 end-point

  3. Activate the CC function.

    # Configure Device A.

    [DeviceA] interface atm 1/0/0
    [DeviceA-Atm1/0/0] oam
    [DeviceA-Atm1/0/0-fatm-oam] cc 0/40 0/41 end-to-end both

    # Configure Device B.

    [DeviceB] interface atm 1/0/0
    [DeviceB-Atm1/0/0] oam
    [DeviceB-Atm1/0/0-fatm-oam] cc 0/40 end-to-end both
    [DeviceB-Atm1/0/0-fatm-oam] cc 0/42 end-to-end both

    # # Configure Device C.

    [DeviceC] interface atm 1/0/0
    [DeviceC-Atm1/0/0] oam
    [DeviceC-Atm1/0/0-fatm-oam] cc 0/41 0/42 end-to-end both

  4. Verify the configuration.

    # Display the OAM configuration on the Router.

    Use the display on Device A as an example:

    <DeviceA> system-view
    [DeviceA] interface atm 1/0/0
    [DeviceA-Atm1/0/0] oam
    [DeviceA-Atm3/0/1-fatm-oam] display atm oam configuration atm 1/0/0
    Interface       PVC      Attribute   CC func   CC dir    CC attr
    ---------      -----     ---------   -------   ------    -------
    Atm1/0/0      0/40      end-point   enable    both      end-to-end
    Atm1/0/0      0/41      end-point   enable    both      end-to-end
    Current displayed item(s) is : 2

    # Display the OAM statistics of the PVC on the Router.

    Use the display on Device A as an example:

    <DeviceA> display atm oam statistics atm 1/0/0 0/40
    Total number of received OAM Cells : 0
    Number of received AIS Cells       : 0
    Number of received RDI Cells       : 0
    Number of received loopback cells  : 0
    Number of received CC cells        : 0
    Number of received crc error cells : 0
    Number of received other cells     : 0
    Total number of sent OAM Cells     : 88
    Number of sent AIS Cells           : 0
    Number of sent RDI Cells           : 44
    Number of sent loopback cells      : 0
    Number of sent CC cells            : 44
