Example for Configuring LMSP on a CPOS-Trunk

Example for Configuring LMSP on a CPOS-Trunk

In this example, a CPOS-Trunk is configured on the Router to aggregate multiple E1 links connected to mid-range-and-low-end devices and identify devices with different timeslots. In addition, LMSP is configured on the CPOS interfaces of the Router to implement protection switching.

Networking Requirements

As shown in Figure 13-6, mid-range-and-low-end devices are connected to the transport network through E1 links. These E1 links are aggregated into a CPOS-Trunk interface configured on Device A. Device A uses timeslots to identify these devices. The CPOS-Trunk interface on Device A consists of two CPOS interfaces. Single-chassis LMSP needs to be configured on the CPOS interfaces to improve data transfer reliability.

In real-world situations, mid-range-and-low-end devices are usually connected to CPOS interfaces over a multi-layer transport network. Therefore, relay devices and other transport means are probably involved.

Figure 13-6 Networking diagram for configuring LMSP on a CPOS-Trunk
NOTE:

The configurations in this example are performed on Device-A. HUAWEI NE40E-M2 Series can function as Device-A.



Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure single-chassis LMSP on the two CPOS interfaces and add the CPOS interfaces to a CPOS-Trunk interface.
  2. Bundle timeslots of E1 channels in the CPOS-Trunk interface to create Trunk-Serial interfaces and add the Trunk-Serial interfaces into a Global-MP-Group interface.

Data Preparation

To complete the configuration, you need the following data:

  • LMSP parameters

  • CPOS-Trunk interface parameters

  • Global-MP-Group interface number

Procedure

  1. Configure single-chassis LMSP.
    1. Configure single-chassis LMSP on Device A.

      [*DeviceA-Cpos0/2/0] commit
      [~DeviceA-Cpos0/2/0] quit

    2. Create a CPOS-Trunk interface on Device A and add CPOS interfaces to the CPOS-Trunk interface.

      [~DeviceA] interface cpos-trunk 0
      [*DeviceA-Cpos-Trunk0] commit
      [~DeviceA-Cpos-Trunk0] quit
      [~DeviceA] controller cpos 0/1/0
      [~DeviceA-Cpos0/1/0] cpos-trunk 0
      [*DeviceA-Cpos0/1/0] commit
      [~DeviceA-Cpos0/1/0] quit
      [~DeviceA] controller cpos 0/2/0
      [~DeviceA-Cpos0/2/0] cpos-trunk 0
      [*DeviceA-Cpos0/2/0] commit
      [~DeviceA-Cpos0/2/0] quit

  2. Configure the CPOS-Trunk interface.
    1. Bundle timeslots of E1 channels in the CPOS-Trunk interface.

      [~DeviceA] interface cpos-trunk 0
      [~DeviceA-Cpos-Trunk0] e1 1 channel-set 1 timeslot-list 1-15
      [*DeviceA-Cpos-Trunk0] e1 2 channel-set 2 timeslot-list 17-31
      [*DeviceA-Cpos-Trunk0] commit
      [~DeviceA-Cpos-Trunk0] quit

    2. Create a Global-MP-Group interface.

      [~DeviceA] interface global-mp-group 0
      [*DeviceA-Global-Mp-Group0] shutdown
      [*DeviceA-Global-Mp-Group0] commit
      [~DeviceA-Global-Mp-Group0] quit

    3. Add Trunk-Serial interfaces to the Global-MP-Group interface.

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

    4. Restart Trunk-Serial interfaces and the Global-MP-Group interface.

      [~DeviceA] interface global-mp-group 0
      [~DeviceA-Global-Mp-Group0] undo shutdown
      [*DeviceA-Global-Mp-Group0] commit
      [~DeviceA-Global-Mp-Group0] quit

    [~DeviceA] display aps group 1
    APS Group  1: Cpos0/1/0 working channel 1(Active)
                   Cpos0/2/0 protection channel 0(Inactive)
                   Unidirectional, 1+1 mode, Revert time(6 minutes)
                   No Request on Both Working and Protection Side
