Pre-configuring the Transmission Medium Type on an Optical Interface

Pre-configuring the Transmission Medium Type on an Optical Interface

Context

Some functions can be configured on an optical interface only after the interface connects to a transmission medium (such as an optical module or copper module). Therefore, optical interfaces must connect to transmission media before having these functions configured. Sometimes the installation personnel and configuration personnel are different. The configuration personnel can configure services only after the installation personnel install the transmission media on interfaces. As a result, the service deployment time on interfaces is lengthened. The configuration personnel can pre-configure the transmission medium type on optical interfaces and configure functions on the interfaces. These functions take effect after the installation personnel install the correct transmission media on the interfaces. In this way, the configuration flexibility is improved and the service deployment time is shortened.

The transmission medium type pre-configuration function can be configured on an optical interface only when the interface does not connect to a transmission medium or is shut down. If the installed transmission medium type is the same as the pre-configured transmission medium type, the interface has the condition to go Up and the configuration takes effect. If the installed transmission medium type differs from the pre-configured transmission medium type, the interface cannot go Up. To make the interface go Up, change the transmission medium type or modify the conflict policy.

If the installed transmission medium type differs from the pre-configured transmission medium type, and the two transmission media have incompatible configurations, the interface status varies depending on the used transmission medium type as follows:
  • If the installed transmission medium type is used, incompatible configurations (such as auto-negotiation mode, rate, and duplex mode) on the interface are lost and the interface goes Up.

  • If the pre-configured transmission medium type is used, incompatible configurations on the interface are saved and the interface goes Down. You can delete incompatible configurations to make the interface go Up.

Procedure

  1. Run system-view

    The system view is displayed.

  2. (Optional) Run device conflict-policy keep-config

    The conflict policy is configured to be based on the pre-configured transmission medium type.

    By default, the conflict policy is based on the installed transmission medium type.

  3. Run interface interface-type interface-number

    The interface view is displayed.

    You can enter the corresponding interface view based on the transmission medium type to be pre-configured.

  4. Run device transceiver transceiver-type

    The transmission medium type is pre-configured on the interface.

    By default, no transmission medium type is pre-configured on an interface.

  5. (Optional) Run undo shutdown

    The interface is enabled.

    Perform this step only when the optical interface is shut down.

  6. Run commit

    The configuration is committed.

Verifying the Configuration

Run the display this command in the interface view to check the pre-configured transmission medium.

Follow-up Procedure

If the installed transmission medium differs from the pre-configured transmission medium, the interface status varies according to the configured conflict policy.
  • If the conflict policy is based on the installed transmission medium type, the interface is initialized based on the installed transmission medium and has the condition to go Up. In addition, the configuration based on the pre-configured transmission medium type is deleted.

  • If the conflict policy is based on the pre-configured transmission medium type, the configuration based on the pre-configured transmission medium type is retained on the interface but the interface does not go Up. You need to install the pre-configured transmission medium to make the interface have the condition to go Up and make the configuration on the interface take effect. You can also make the interface have the condition to go Up using the following methods, but the configuration based on the pre-configured transmission medium type is deleted.
    • Run the undo device conflict-policy keep-config command to change the conflict policy to be based on the installed transmission medium type, and remove and reinstall the transmission medium.
    • Run the shutdown command to shut down the interface, run the undo device transceiver command to delete the pre-configured transmission medium type, set the transmission medium type to the installed transmission medium type, and run the undo shutdown command.
    • Run the shutdown command to shut down the interface, run the undo device transceiver command to delete the pre-configured transmission medium type, and run the undo shutdown command. This method is not recommended because no pre-configured transmission medium information exists on the interface.
  • If the pre-configured transmission medium is a high-speed cable but an optical module is installed, the optical module may be burned. Ensure that the installed transmission medium is the same as the pre-configured transmission medium.

  • If the installed optical module type is displayed as Unknown, the system cannot identify the optical module. Only when the pre-configured transmission medium type and the installed transmission medium type have the same bandwidth, the interface may go Up; otherwise, the interface cannot go Up. To ensure that the interface works properly, you are advised to use an optical module that is certified for Huawei Ethernet switches.
