Adding Member Interfaces to an Eth-Trunk

Adding Member Interfaces to an Eth-Trunk

Context

You can add member interfaces to an Eth-Trunk in the Eth-Trunk interface view or member interface view.

Procedure

  • Add member interfaces to an Eth-Trunk in the Eth-Trunk interface view.
    1. Run:

      system-view

      The system view is displayed.

    2. Run:

      interface eth-trunk trunk-id

      The Eth-Trunk interface view is displayed.

    3. Run:

      trunkport interface-type { interface-number1 [ to interface-number2 ] } &<1-8>

      A member interface is added to the Eth-Trunk.

      NOTE:

      When you add member interfaces to an Eth-Trunk in a batch, if one interface cannot be added to the Eth-Trunk, all subsequent interfaces in the batch cannot be added to the Eth-Trunk, either.

  • Add member interfaces to an Eth-Trunk in the member interface view.
    1. Run:

      system-view

      The system view is displayed.

    2. Run:

      interface interface-type interface-number

      The member interface view is displayed.

    3. Run:

      eth-trunk trunk-id

      The member interface is added to an Eth-Trunk.

      NOTE:
      AR503GW-LM7, AR503GW-LcM7, AR509G-L-D-H, and AR509G-Lc do not support this command.

    When adding an interface to an Eth-Trunk, pay attention to the following points:

    • An Eth-Trunk contains a maximum of 8 member interfaces.

    • A member interface cannot be configured with some services or static MAC addresses.
    • When adding an interface to an Eth-Trunk, ensure that the interface uses the default link type.
    • An Eth-Trunk cannot be added to another Eth-Trunk.
    • An Ethernet interface can be added to only one Eth-Trunk. To add the Ethernet interface to another Eth-Trunk, delete it from the Eth-Trunk first.
    • Member interfaces of an Eth-Trunk must use the same type.
    • If an interface of the local device is added to an Eth-Trunk, an interface of the remote device directly connected to the interface of the local device must also be added to an Eth-Trunk so that the two ends can communicate.
    • After interfaces are added to an Eth-Trunk, the Eth-Trunk learns MAC addresses and ARP entries but member interfaces do not.
    • Devices at both ends of an Eth-Trunk must use the same number of physical interfaces, interface rate, duplex mode, flow control mode and jumbo.

Follow-up Procedure

You can configure Eth-Trunk member interfaces to send trap messages after the Eth-Trunk member interface status changes. After the device receives a trap message, check whether the device fails or recovers.

If you need to know the status change of the member interface of a specified Eth-Trunk, run the trunk-member trap in private-mib enable command to enable Eth-Trunk member interfaces to use the proprietary MIB to send trap messages. The trap messages sent by using the proprietary MIB carry Eth-Trunk IDs, whereas the trap messages sent by using the public MIB do not carry Eth-Trunk IDs.

NOTE:

After the trunk-member trap in private-mib enable command is configured, Eth-Trunk member interfaces only use the proprietary MIB to send trap messages. To view these trap messages, use the Huawei proprietary MIB.
