Configuring Interface Split and Merge

Configuring Interface Split and Merge

Context

Some 40GE optical interfaces can be used as independent interfaces or each can be split into four 10GE interfaces. With the interface split function, a device with 40GE interfaces can provide high-density 10GE interfaces, and can connect to 40GE or 10GE interfaces on the remote device. This function allows for flexible networking and lowers hardware costs.

After an interface is split, the original interface does not work. The new 10GE or 40GE optical interfaces support the same configurations and features as common optical interfaces, except that they are numbered in a different way. For details about the numbering rule, see Interface Numbering Rules. Table 3-4 lists connection modes for split 40GE interfaces.

Connection Mode

Description

Configuration Reference

1-to-4 high-speed cable (or copper cable)

The cable provides fixed optical modules that can be directly installed on optical interfaces, lowering costs. The cable length is fixed and the maximum length is 5 m.

1-to-4 high-speed cable models: QSFP-40G-CU1M, QSFP-40G-CU3M, and QSFP-40G-CU5M

For details, see "Cables - High-Speed Cable" in the S1720, S2700, S5700, and S6720 Series Ethernet Switches Hardware Description.

1-to-4 active optical cable (AOC)

The cable provides fixed optical modules that can be directly installed on optical interfaces, lowering costs. The cable length is fixed and the maximum length is 10 m.

1-to-4 AOC model: QSFP-4SFP10-AOC10M

For details, see "Cables - Optical Fiber" in the S1720, S2700, S5700, and S6720 Series Ethernet Switches Hardware Description.

1-to-4 40GE optical module + common 10GE optical module + optical fiber

The local and remote interfaces can have a 1-to-4 40GE optical module and four common 10GE optical modules installed respectively and be connected using a dedicated 1-to-4 optical fiber. The communication distance can be adjusted. The optical fibers do not provide optical modules and the costs are high.

1-to-4 40GE optical module models: QSFP-40G-iSR4, QSFP-40G-eSR4, and QSFP-40G-iSM4

1-to-4 optical fiber model: MPO-4*DLC

For details, see "Cables - Optical Fiber" and "Pluggable Modules for Interfaces - Models and Parameters" in the S1720, S2700, S5700, and S6720 Series Ethernet Switches Hardware Description.

Common 40GE optical module + optical fiber

If the local and remote interfaces are both split 40GE interfaces, they can have the same 40GE QSFP+ optical modules installed and be connected using an optical fiber.

For details, see "Cables - Optical Fiber" and "Pluggable Modules for Interfaces - Models and Parameters" in the S1720, S2700, S5700, and S6720 Series Ethernet Switches Hardware Description.

NOTE:
  • After configuring interface split or merge, save the configuration and restart the device to make the configuration take effect.

If interface split or merge is configured on an interface, the original configuration on the interface is lost. Therefore, exercise caution when deciding to perform the interface split or merge operation.

Procedure

  • Configuring Interface Split

    • Splitting a 40GE interface into four 10GE interfaces

      1. Run:

        system-view

        The system view is displayed.

      2. Run:

        interface 40ge interface-number

        The 40GE interface view is displayed.

      3. Run:

        port split split-type 40GE:4*XGE

        The 40GE interface is split into four 10GE interfaces.

        By default, a 40GE interface is used as an independent interface.

  • Configuring Interface Merge

    • Merging four converted 10GE interfaces into a 40GE interface

      1. Run:

        system-view

        The system view is displayed.

      2. Run:

        interface xgigabitethernet interface-number

        The view of a converted 10GE interface is displayed.

      3. Run:

        undo port split

        The four converted 10GE interfaces are merged into a 40GE interface.

        To merge converted interfaces, you only need to run this command in the view of one converted interface.

Checking the Configuration

Run the display port split [ slot slot-id ] command to view interface split information.
