Example for Configuring CPOS Interfaces to Converge T1 Lines

Networking Requirements

As shown in Figure 15-12, RouterA connects to seven Routers B through H. Each of the seven Routers connects to RouterA using a T1 link. RouterA uses a CPOS interface to aggregate these T1 links.

When another T1 link is added to RouterB to provide more bandwidth, the two T1 links need to be bound using MP-Group interfaces.

The requirements on RouterA are as follows:
  • RouterA uses the clock signals transmitted from the SDH network.
  • The RouterA's CPOS interface uses SDH as the frame format, and the AUG multiplexing mode is au-4.
Figure 15-12  Networking diagram for configuring CPOS interfaces to converge T1 lines

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure line attributes, including clock mode, frame format, and AUG multiplexing mode, on RouterA's CPOS interface.
    NOTE:

    By default, the clock mode is slave clock, frame format is SDH, and AUG multiplexing mode is au-4. The default line attributes on CPOS interface do not need to be modified in this example.

  2. Create and configure an MP-Group interface on RouterA and RouterB.
  3. Configure a T1 channel on the CPOS interface of RouterA and bind the T1 channel to the MP-Group interface.
  4. Bind the T1-F interface to the MP-Group interface on RouterB.

Procedure

  1. Create and configure an MP-Group interface on RouterA.

    <Huawei> system-view
    [Huawei] sysname RouterA
    [RouterA] interface mp-group 0/0/1
    [RouterA-Mp-group0/0/1] ip address 100.10.10.1 24
    [RouterA-Mp-group0/0/1] quit

  2. Configure a T1 channel for a CPOS interface.

    [RouterA] controller cpos 1/0/0
    [RouterA-Cpos1/0/0] t1 1 channel-set 1 timeslot-list 1-24
    [RouterA-Cpos1/0/0] t1 2 channel-set 2 timeslot-list 1-24
    [RouterA-Cpos1/0/0] quit

  3. Bind the T1 channel to the MP-Group interface.

    [RouterA] interface serial 1/0/0/1:0
    [RouterA-Serial1/0/0/1:0] ppp mp mp-group 0/0/1
    [RouterA-Serial1/0/0/1:0] quit
    [RouterA] interface serial 1/0/0/2:0
    [RouterA-Serial1/0/0/2:0] ppp mp mp-group 0/0/1
    [RouterA-Serial1/0/0/2:0] quit

  4. Create and configure an MP-Group interface on RouterB.

    <Huawei> system-view
    [Huawei] sysname RouterB
    [RouterB] interface mp-group 0/0/1
    [RouterB-Mp-group0/0/1] ip address 100.10.10.2 24
    [RouterB-Mp-group0/0/1] quit

  5. Bind the T1-F interface to the MP-Group interface on RouterB.

    [RouterB] interface serial 1/0/0
    [RouterB-Serial1/0/0] ft1 timeslot-list 1-24
    [RouterB-Serial1/0/0] ppp mp mp-group 0/0/1
    [RouterB-Serial1/0/0] quit
    [RouterB] interface serial 2/0/0
    [RouterB-Serial2/0/0] ft1 timeslot-list 1-24
    [RouterB-Serial2/0/0] ppp mp mp-group 0/0/1
    [RouterB-Serial2/0/0] quit

  6. Verify the configuration.
