The set interface gigabit-ethernet breakout command breaks out the 40G and 100G ports into four interfaces.
set interface gigabit-ethernet <port-name> breakout <true | false>
Specifies the port name of 40G or 100G port.
breakout <true | false>
Specifies the breakout mode. The value could be true or false.
The 40GE interfaces can be split into 4 x 10GE sub-interfaces, the 100GE interface can be split into 4 x 25G or 4 x 10G Ethernet sub-interfaces. By default, the 100G interface is split into 4 x 25G Ethernet sub-interfaces. If you want to split into 4 x 10G Ethernet sub-interfaces, you need to configure the four sub-interfaces rate to 10G through the command line after port breakout. Note: The rate of the four sub-interfaces is required to be consistent.
After a single interface is split into four sub-interfaces, the 10GE optical sub-interface or the 25GE optical sub-interface supports the same configurations and features as other non-breakout optical interface except that the interface is named in a different way. For example, the port name of the 100GE and 40GE optical interfaces is xe-1/1/n before port breakout; however, after port breakout the port names of the four sub-interfaces are xe-1/1/n.1, xe-1/1/n.2, xe-1/1 /n.3 and xe- 1/1/n.4.
- Split the 40GE port xe-1/1/25 into 4 x 10GE ports.
- Do not split the 100G port xe-1/1/53.
