Overview
The 400GE optical interface can be used as a single interface or split into two or four independent and logical interfaces. The detailed information is shown as below.

400G | 400G | 4*100G |

Configuring Port Breakout and Port Merge
To configure port breakout for the 400GE interfaces of the switch, take the following steps:.
Step 1 Enable the port breakout function.
set interface gigabit-ethernet <port-name> breakout true
Step 2 Specify the breakout type as 4 x 100G or 2 x 200G.
set interface gigabit-ethernet <port-name> breakout-type {4*100G | 2*200G}
NOTEs:
To cancel the interface split, use set interface gigabit-ethernet <port-name> breakout false command to restore the split interfaces into one interface.
If you enable the breakout function of interface without configuring the breakout-type, the 400GE interface will be split into four 100G Ethernet interfaces by default.
The interface name is modified after port breakout or merge, that is the original interface does not exist, and you need to manually delete the configurations associated with the original interfaces before restarting system, to make sure that the configuration file can be loaded normally when system boots up.
Step 3 Commit the configuration.

Step 4 Restart PicOS to make the setting take effect. Note: the split interfaces cannot be viewed before restarting PicOS.
sudo systemctl restart picos
Step 5 View the interface information after system startup. You can view the information of split interfaces.
