Split 100G into 4×25G

Goal​

The goal of the steps below is to configure the switch to split each 100G interface into 4 interface each capbable of 25G.

This way, the switch can work well with the existing 4 X 25G sfp pcie cards.

Steps Before Using the Switch​

Step 1: Connect the Breakout Cable​

  • Connect one end of the breakout cable to the switch 100G port.

  • The other end should connect to the PC, split between the PCIe network cards.

  • Each network card should have two cables connected.

Step 2: Connect a Laptop for Configuration​

  • Use an ethernet cable to connect your laptop directly to the switch.

  • The switch has a port marked MGT (management). Connect the cable there and to your laptop.

  • Once configuration is done, this cable can be disconnected.

Step 3: Set Laptop IP Address​

  • By default, the switch uses IP 192.168.1.1.

  • Set your laptop LAN IP to the same range (e.g., 192.168.1.10).

Step 4: Access the Web Management Interface​

  • Open a browser and navigate to 192.168.1.1.

  • You should see the web-based management system of the switch.

Step 5: Login to Web Interface​

  • Use the following credentials:

    • User: admin

    • Password: admin

Switch Configuration via Terminal​

Step 6: Open a Terminal​

  • On your laptop, open PuTTY (or another SSH client).

  • Connect to the switch:


    ssh admin@192.168.1.1

  • Password: admin

Step 7: Split the 100G Interfaces​

  • The switch has two 100G interfaces.

  • We need to split each into 4 × 25G for use with the breakout cable.

Run the following commands:


configure terminal

split interface eth-0-25 25G

split interface eth-0-26 25G

exit

write memory

reload

  • Press Enter to confirm the reboot.

Summary​

At the end of this process, you should have the 100G interface splitted into 4 interfaces.
