Creating a LAG

Creating a LAG

Context

Each LAG has one logical interface, that is, an Eth-Trunk. Before configuring link aggregation, create an Eth-Trunk.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface eth-trunk trunk-id

    An Eth-Trunk is created and the Eth-Trunk interface view is displayed.

    If the specified Eth-Trunk already exists, this command directly displays the Eth-Trunk interface view.

    trunk-id defines the Eth-Trunk ID. The value ranges of different models are different. Table 3-5 lists value ranges of different models.
    Table 3-5 Value ranges of different models

    Product Model

    Value Range

    CE5810EI

    The value range cannot be adjusted. The value of trunk-id is in the range 0 to 127. Each Eth-Trunk allows a maximum of eight member interfaces.

    CE6870EI and CE6875EI

    The value range can be adjusted using the assign forward eth-trunk mode { 256 | 512 | 1024 } command.

    • When 256 is specified, the value is in the range 0 to 255. Each Eth-Trunk allows a maximum of 64 member interfaces.
    • When 512 is specified, the value is in the range 0 to 511. Each Eth-Trunk allows a maximum of 32 member interfaces. The default value is 512.
    • When 1024 is specified, the value is in the range 0 to 1023. Each Eth-Trunk allows a maximum of 16 member interfaces.

    CE6880EI

    The value range cannot be adjusted. The value of trunk-id is in the range 0 to 1023. Each Eth-Trunk allows a maximum of 64 member interfaces.

    Other models:

    The value range can be adjusted using the assign forward eth-trunk mode { 64 | 128 | 256 | 512 | 1024 } command.

    • When 64 is specified, the value is in the range 0 to 63. Each Eth-Trunk allows a maximum of 32 member interfaces.
    • When 128 is specified, the value is in the range 0 to 127. Each Eth-Trunk allows a maximum of 16 member interfaces. The default value is 128.
    • When 256 is specified, the value is in the range 0 to 255. Each Eth-Trunk allows a maximum of 8 member interfaces.
    • When 512 is specified, the value is in the range 0 to 511. Each Eth-Trunk allows a maximum of 4 member interfaces.
    • When 1024 is specified, the value is in the range 0 to 1023. Each Eth-Trunk allows at most 2 member interfaces.

  3. Run commit

    The configuration is committed.
