Example for Configuring CPOS Interface Interconnection

Example for Configuring CPOS Interface Interconnection

This section provides an example on how to interconnect devices through CPOS interfaces and how to configure MP-group interfaces for link bundling.

Networking Requirements

On the network shown in Figure 5-6, Device A and Device B need to communicate with each other through CPOS interfaces, and MP-group interfaces need to be configured for link bundling.

Figure 5-6 Configuring CPOS interface interconnection
NOTE:

In this example, interface1 and interface2 represent CPOS 0/3/0 and CPOS 0/2/9, respectively.



Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure a working mode for CPOS interfaces and channelize them into synchronous serial interfaces.

  2. Configure MP-group interfaces and add the synchronous serial interfaces to the MP-group interfaces.

Data Preparation

To complete the configuration, you need the following data:

  • Channel number and timeslot number of each E1 channel

  • IP addresses of MP-group interfaces

NOTE:

The interface to be added to an MP-group interface must have the same slot number and card number as the MP-group interface.

The timeslot channels of the serial interfaces on Device A must be the same as those on Device B.

Procedure

  1. Configure a working mode for CPOS interfaces and channelize them into synchronous serial interfaces.

    # Create synchronous serial interfaces on the CPOS interface of Device A.

    <HUAWEI> system-view
    [~HUAWEI] sysname DeviceA
    [*DeviceA] controller cpos 0/3/0
    [*DeviceA-Cpos0/3/0] e1 1 channel-set 1 timeslot-list 1-15
    [*DeviceA-Cpos0/3/0] e1 2 channel-set 1 timeslot-list 16-31
    [*DeviceA-Cpos0/3/0] undo shutdown
    [*DeviceA-Cpos0/3/0] commit
    [~DeviceA-Cpos0/3/0] quit

    # # Create synchronous serial interfaces on the CPOS interface of Device B.

    <HUAWEI> system-view
    [~HUAWEI] sysname DeviceB
    [*DeviceB] controller cpos 0/2/9
    [*DeviceB-Cpos0/2/9] e1 1 channel-set 1 timeslot-list 1-15
    [*DeviceB-Cpos0/2/9] e1 2 channel-set 1 timeslot-list 16-31
    [*DeviceB-Cpos0/2/9] undo shutdown
    [*DeviceB-Cpos0/2/9] commit
    [~DeviceB-Cpos0/2/9] quit

  2. Configure MP-group interfaces and add the synchronous serial interfaces to the MP-group interfaces.

    # Create an MP-group interface on Device A.

    [~DeviceA] interface mp-group 0/3/0
    [*DeviceA-Mp-group0/3/0] ip address 10.1.1.1 255.255.255.0
    [*DeviceA-Mp-group0/3/0] undo shutdown
    [*DeviceA-Mp-group0/3/0] commit
    [~DeviceA-Mp-group0/3/0] quit

    # Add the synchronous serial interfaces to the MP-group interface on Device A.

    [~DeviceA] interface serial 0/3/0/1:1
    [~DeviceA-Serial0/3/0/1:1] link-protocol ppp
    [*DeviceA-Serial0/3/0/1:1] ppp mp mp-group 0/3/0
    [*DeviceA-Serial0/3/0/1:1] commit
    [~DeviceA-Serial0/3/0/1:1] quit
    [~DeviceA] interface serial 0/3/0/2:1
    [~DeviceA-Serial0/3/0/2:1] link-protocol ppp
    [*DeviceA-Serial0/3/0/2:1] ppp mp mp-group 0/3/0
    [*DeviceA-Serial0/3/0/2:1] commit
    [~DeviceA-Serial0/3/0/2:1] quit

    # Create an MP-group interface on Device B.

    [~DeviceB] interface mp-group 0/2/9
    [*DeviceB-Mp-group0/2/9] ip address 10.1.1.2 255.255.255.0
    [*DeviceB-Mp-group0/2/9] undo shutdown
    [*DeviceB-Mp-group0/2/9] commit
    [~DeviceB-Mp-group0/2/9] quit

    # Add the synchronous serial interfaces to the MP-group interface on Device B.

    [~DeviceB] interface serial 0/2/9/1:1
    [~DeviceB-Serial0/2/9/1:1] link-protocol ppp
    [*DeviceB-Serial0/2/9/1:1] ppp mp mp-group 0/2/9
    [*DeviceB-Serial0/2/9/1:1] commit
    [~DeviceB-Serial0/2/9/1:1] quit
    [~DeviceB] interface serial 0/2/9/2:1
    [~DeviceB-Serial0/2/9/2:1] link-protocol ppp
    [*DeviceB-Serial0/2/9/2:1] ppp mp mp-group 0/2/9
    [*DeviceB-Serial0/2/9/2:1] commit
    [~DeviceB-Serial0/2/9/2:1] quit

  3. Verify the configuration.

    # On Device A, ping the IP address of the MP-group interface on Device B. The command output shows that the ping is successful.

    [~DeviceA] ping 10.1.1.2
    PING 10.1.1.2: 56  data bytes, press CTRL_C to break
        Reply from 10.1.1.2: bytes=56 Sequence=1 ttl=255 time=29 ms
