set interface gigabit-ethernet breakout

The set interface gigabit-ethernet breakout command breaks out the 40GE, 100GE and 400GE interfaces into four sub-interfaces. The 40GE interface is split into four 10GE interfaces; the 100GE interface is split into four 25GE interfaces; the 400GE interface is split into four 100GE interfaces.

NOTEs:

Restart PICOS after committing this command to make the setting take effect.
For 400GE interfaces, after executing this command, you can furtherly configure the breakout type through command set interface gigabit-ethernet breakout-type. For details, see Configuring set interface gigabit-ethernet breakout-type.
When performing the port breakout and merge operation, before restarting the system, you need to manually delete the configurations of the unavailable interfaces, to make sure that the configuration file can be loaded normally when the system boots up.
From PICOS 3.7.3.4, AS7726_32X supports splitting a 100G port into 2x50G or 4x25G or 4x10G ports using command set interface gigabit-ethernet <port-name> breakout true and set interface gigabit-ethernet breakmap under L2/L3 mode.

Command Syntax

set interface gigabit-ethernet <port-name> breakout <true | false>

Parameter

Parameter

Description

gigabit-ethernet <port-name>

Specifies the port name of 40G, 100G or 400G port.

breakout <true | false>

Specifies the breakout mode. The value could be true or false.

true: breakout the specified port.

false: merge the specified port.

Usage Guidelines

The 40GE interfaces can be split into 4 x 10GE interfaces, the 100GE interface can be split into 4 x 25G or 4 x 10G Ethernet interfaces. By default, the 100G interface is split into 4 x 25G Ethernet interfaces. If you want to split into 4 x 10G Ethernet interfaces, you need to configure the four interfaces rate to 10G through the command line after port breakout. Note: The rate of the four interfaces is required to be consistent.

The 400GE interfaces can be split into 4 x 100GE or 2 x 200GE interfaces. By default, the 400GE interface is split into 4 x 100GE interfaces. To split into 2 x 200G Ethernet interfaces, execute the set interface gigabit-ethernet breakout-type command.

After a single interface is split into four interfaces, the 10GE split optical interface or the 25GE split optical 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 interfaces are xe-1/1/n.1, xe-1/1/n.2, xe-1/1 /n.3 and xe- 1/1/n.4.

Example

Split the 40GE port xe-1/1/25 into 4 x 10GE ports.

admin@XorPlus# set interface gigabit-ethernet xe-1/1/25 breakout true
admin@XorPlus# co
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.
admin@XorPlus# exit
admin@XorPlus> request system reboot

Do not split the 100G port xe-1/1/53.

admin@XorPlus# set interface gigabit-ethernet xe-1/1/53 breakout false
admin@XorPlus# co
