Example for Configuring CPOS Interfaces to Be Connected Through Optical Fibers

Example for Configuring CPOS Interfaces to Be Connected Through Optical Fibers

Networking Requirements

In Figure 15-10, CPOS interfaces of RouterA and RouterB are connected through optical fibers.

The existing configurations are as follows:

  • The SDH transmission mechanism is used in areas where RouterA and RouterB reside.
  • AU-3 is used in areas where RouterA and RouterB reside.
  • RouterB is an Alcatel device.
  • The clock mode of the CPOS interface on RouterB is slave.
  • The overhead bytes of the CPOS interface on RouterB are as follows: c2: 3, s1: 14, j0: abc(16 byte-mode), and j1: xyz(16 byte-mode).

To ensure successful connection, configure the CPOS interface of RouterA.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Set the connection mode of RouterA to Alcatel.
  2. Set the frame format to SDH for the CPOS interface on RouterA.
  3. Set the AUG multiplexing mode to AU-3 for the CPOS interface on RouterA.
  4. Set the overhead bytes of the CPOS interface on RouterA as follows: c2: 3, s1:14, j0: abc(16 byte-mode), and j1: xyz(16 byte-mode) and ensure that overhead bytes are the same on both ends.
  5. Set the clock mode of the CPOS interface on RouterA to master and ensure that RouterA has the different clock mode than RouterB.

Procedure

  1. Set the connection mode of RouterA to Alcatel.

    <Huawei> system-view
    [Huawei] sysname RouterA
    [RouterA] controller cpos 1/0/0
    [RouterA-Cpos1/0/0] multi-channel align-mode alcatel
    

  2. Set the frame format to SDH for the CPOS interface on RouterA.

    [RouterA-Cpos1/0/0] frame-format sdh
    

  3. Set the AUG multiplexing mode to AU-3 for the CPOS interface on RouterA.

    [RouterA-Cpos1/0/0] multiplex mode au-3
    

  4. Set the overhead bytes of the CPOS interface on RouterA.

    [RouterA-Cpos1/0/0] flag c2 3
    [RouterA-Cpos1/0/0] flag s1 14
    [RouterA-Cpos1/0/0] flag j0 16byte-mode abc
    [RouterA-Cpos1/0/0] flag j1 16byte-mode xyz
    

  5. Set the clock mode of the CPOS interface on RouterA to master.

    [RouterA-Cpos1/0/0] clock master
    [RouterA-Cpos1/0/0] quit
    

  6. Verify the configuration.

    # Check information about all channels of CPOS 1/0/0. You can view that the physical status of the interface is Up.

    [RouterA] display controller cpos 1/0/0
    Cpos1/0/0 current state : UP
