Configuring a CPOS-Trunk Interface

Configuring a CPOS-Trunk Interface

Configuring a CPOS-Trunk interface includes creating a CPOS-Trunk interface, adding a CPOS interface to the CPOS-Trunk interface, and creating a trunk serial interface on the CPOS-Trunk interface.

Usage Scenario

A CPOS-Trunk interface is a logical interface that has all the functions of a CPOS interface. It is more reliable because it has multiple CPOS interfaces bundled using the link aggregation technology.

After a CPOS-Trunk interface is created, APS can be configured on the interface.

Pre-configuration Tasks

Before configuring a CPOS-Trunk interface, power on the device and ensure that the self-check succeeds.

Configuration Procedure

Perform one or more of the following configurations as required.

Creating a CPOS-Trunk Interface

Before adding a CPOS interface to a CPOS-Trunk interface, create the CPOS-Trunk interface.

Context

APS can be configured on the trunk serial interface channelized from a CPOS-Trunk interface only after CPOS interfaces are added to the CPOS-Trunk interface.

Procedure

  1. Create a CPOS-Trunk interface.
    1. Run system-view

      The system view is displayed.

    2. Run interface cpos-trunk trunk-id

      A CPOS-Trunk interface is created. If the CPOS-Trunk interface already exists, the CPOS-Trunk interface view is displayed.

  2. Add a CPOS interface to the CPOS-Trunk interface.
    1. Run controller cpos cpos-number

      The CPOS interface view is displayed.

    2. Run cpos-trunk trunk-id

      The CPOS interface is added to the CPOS-Trunk interface.

    NOTE:

    Before adding a CPOS interface to a CPOS-Trunk interface, add the CPOS interface to an LMSP group and configure the interface as a working interface or a protection interface.

    After a CPOS interface is added to a CPOS-Trunk interface, the following situations occur:
    • If you run the shutdown command on the CPOS-Trunk interface, the physical status of both the CPOS-Trunk and CPOS interfaces becomes Administratively DOWN, and the shutdown command configuration is automatically generated for the CPOS interface in the configuration file.
    • If you run the undo shutdown command on the CPOS-Trunk interface, the undo shutdown command configuration is automatically generated for the CPOS interface in the configuration file.

  3. Run commit

    The configuration is committed.

Configuring the Working Mode of a CPOS-Trunk Interface

Context

A CPOS-Trunk interface can work in either clear channel mode or channelized mode. Trunk serial interfaces with different transmission rates can be generated in the two modes to meet different bandwidth requirements of services.
NOTE:

The configuration of channelized mode is supported only on the Admin-VS.

Procedure

  • Configure a CPOS-Trunk interface to work in channelized mode.
    • Configure an E1 channel of a CPOS-Trunk interface to work in clear channel mode so that a trunk serial interface is generated.

      1. Run system-view

        The system view is displayed.

      2. Run interface cpos-trunk trunk-id

        The CPOS-Trunk interface view is displayed.

      3. Run e1 e1-number unframed

        An E1 channel of the CPOS-Trunk interface is configured to work in clear channel mode, and a trunk serial interface is generated.

        After the trunk serial interface in clear channel mode is generated, you can run the interface trunk-serial cpos-trunk-id/e1-number:0 command to enter the trunk serial interface view.

      4. Run commit

        The configuration is committed.

    • Configure an E1 channel of a CPOS-Trunk interface to work in channelized mode so that a trunk serial interface in channelized mode can be generated.

      1. Run system-view

        The system view is displayed.

      2. Run interface cpos-trunk trunk-id

        The CPOS-Trunk interface view is displayed.

      3. Run e1 e1-number channel-set set-number timeslot-list

        Timeslots of an E1 channel of the CPOS-Trunk interface are bundled, and a trunk serial interface is generated.

        After the trunk serial interface in channelized mode is generated, you can run the interface trunk-serial cpos-trunk-id/e1-number:set-number command to enter the trunk serial interface view.

      4. Run commit

        The configuration is committed.

  • Configure a CPOS-Trunk interface to work in clear channel mode.
    1. Run system-view

      The system view is displayed.

      The CPOS-Trunk interface view is displayed.

    3. Run using vc4

      The CPOS-Trunk interface is configured to work in clear channel mode, and a trunk serial interface is created on the CPOS-Trunk interface. The trunk serial interface transmits data at a high rate, without timeslot division.

    4. Run commit

      The configuration is committed.

Configuring a Working Mode for an E1 Channel of a CPOS-Trunk Interface

An E1 channel of a CPOS-Trunk interface can be configured to work in clear channel or channelized mode to form trunk serial interfaces with different bandwidths.

Creating a Global MP-Group or IMA-Group Interface and Adding a Trunk Serial Interface to It

To increase transmission bandwidth and improve network reliability, add trunk serial interfaces to a global MP-group or IMA-group interface.

Context

To improve network reliability, a protection channel can be configured to take over traffic from one or more working channels if the working channels fail.

Before deploying and protecting PPP or ATM services on CPOS interfaces, add two CPOS interfaces to a CPOS-Trunk interface and channelize the CPOS-Trunk interface into trunk serial interfaces. Then, add the trunk serial interfaces to a global MP-group or IMA-group interface to carry the PPP or ATM services. If one CPOS link fails, the other CPOS link takes over traffic.

Procedure

  • Create a global MP-group interface and add a trunk serial interface to it.
    1. Create a global MP-group interface.

      1. Run system-view

        The system view is displayed.

      2. Run interface global-mp-group global-mp-group-number

        A global MP-group interface is created.

      3. Run commit

        The configuration is committed.

    2. Add a trunk serial interface to the global MP-group interface.

      1. Run system-view

        The system view is displayed.

      2. Run interface trunk-serial trunk-serial-id

        The trunk serial interface view is displayed.

      3. Run link-protocol ppp

        The link layer protocol is configured as PPP for the trunk serial interface.

      4. Run ppp mp-global global-mp-group global-mp-group-number

        The trunk serial interface is added to the global MP-group interface.

      5. Run commit

        The configuration is committed.

  • Create a global IMA-group interface and add a trunk serial interface to it.
    1. Create a global IMA-group interface.

      1. Run system-view

        The system view is displayed.

      2. Run interface global-ima-group global-ima-group-number

        A global IMA-group interface is created.

      3. Run commit

        The configuration is committed.

    2. Add a trunk serial interface to the global IMA-group interface.

      1. Run system-view

        The system view is displayed.

      2. Run interface trunk-serial trunk-serial-id

        The trunk serial interface view is displayed.

      3. Run link-protocol atm

        The link layer protocol is configured as ATM for the trunk serial interface.

      4. Run ima global-ima-group global-ima-group-number

        The trunk serial interface is added to the global IMA-group interface.

        NOTE:
        After a trunk serial interface is added to a global IMA-group interface, the interface type previously configured for the global IMA-group interface becomes invalid. To reconfigure an interface type for the global IMA-group interface, run the atm interface-type { uni | nni } command in the global IMA-group interface view.
        • If a device connects to a user-side device, configure the IMA-group interface as a UNI.

        • If a device connects to another network-side device, configure the IMA-group interface as an NNI.

        \
      5. Run commit

        The configuration is committed.
