Splitting a 40GE Interface

Splitting a 40GE Interface

  1. Configure the interface split mode. (Only the CE8850-64CQ-EI, CE7850EI and CE7855EI support this step.)

    <HUAWEI> system-view
    [~HUAWEI] port split mode mode2 slot 1  //Configure the interface split mode.
    Warning: This operation may cause the split configurations on the board to be lost. This mode will take effect after board is reset.
     Continue? [Y/N]: y
    [*HUAWEI] commit
    [~HUAWEI] quit
    <HUAWEI> save
    <HUAWEI> reset slot 1  //The configuration takes effect after the card resets.
  2. Configure interface split.

    <HUAWEI> system-view
    [~HUAWEI] port split dimension interface 40ge 1/0/1 split-type 4*10GE  //Set the interface split mode of 40GE1/0/1 to 4*10GE. 40GE interfaces on the CE8860EI support the 2*10G split mode.
    Warning: This operation will cause all the other configurations on the port to be lost, and the configuration will take effect after 
    the board is reset. Continue? [Y/N]: y 
    [*HUAWEI] commit
    [~HUAWEI] quit
    <HUAWEI> save
    <HUAWEI> reset slot 1  //The configuration takes effect after the card resets.

    After interface split or merge is configured on an interface, the original configuration on the interface will be lost. For device models that do not support dynamic interface split, you need to save the configuration and restart the card or switch to make the configuration take effect. Therefore, exercise caution when deciding to restart the switch.

    For device models that support dynamic interface split, see Configuration - Interface Management Configuration Guide - Ethernet Interface Configuration - Configuring Attributes for an Optical Interface - Configuring Interface Split.
