set interface gigabit-ethernet breakout-type

The set interface gigabit-ethernet breakout-type command can specify the breakout type as four 100G or two 200G.

NOTEs:

To cancel the split configuration of an interface, use set interface gigabit-ethernet <port-name> breakout false command to restore the split interfaces to 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 and the 200GE interface will be split into four 50G Ethernet interfaces by default.
The interface name is modified after port breakout or merge, you need to manually delete the configurations of the unavailable interfaces before restarting system, to make sure that the configuration file can be loaded normally when system boots up.

Command Syntax

set interface gigabit-ethernet <port-name> breakout-type {4*100G | 2*200G}

Parameter

Parameter	Description
gigabit-ethernet <port-name>	Specifies the name of a 400G or 200G interface.
breakout-type {*4100G \| 2200G*}	Specifies the breakout type as four 100G or two 200G for switches supporting 400G interfaces.

Example

Split the 400GE interface xe-1/1/26 into four 100G Ethernet interfaces.

admin@PICOS# set interface gigabit-ethernet xe-1/1/26 breakout true
admin@PICOS# set interface gigabit-ethernet xe-1/1/26 breakout-type 4*100G
admin@PICOS# commit
Commit OK.
Save done.
Interface breakout setting has been changed, please reboot the system for changes to take effect!
Make sure to delete all the configurations associated with the unavailable interfaces, otherwise loading startup configuration will fail.
