Splitting a 40-GE interface and combining 10-GE breakout
interfaces
Configuration restrictions and guidelines
All interfaces on the LSXM1CGQ6QGHB1, LSXM1CGQ18QGHB1, LSXM1CGQ18QGHF1, and
LSXM1CGQ36HB1 interface modules can be split into four breakout interfaces.
100-GE interfaces on the LSXM1TGS48C2HB1 interface modules cannot be split into four breakout
interfaces.
Interfaces numbered 1 through 4, 17 through 22, 35, and 36 on LSXM1QGS36HB1 interface
modules can be split into four breakout interfaces.
Interfaces numbered 1 through 13, 16, 19, 22, 25, 28, 31, 34, 37, 40, 43, and 46 on
LSXM1QGS48HB1 interface modules can be split into four breakout interfaces.
Splitting a 40-GE interface into four 10-GE breakout interfaces
As a best practice for the long-term system stabilization, reboot the device after configuration.
You can use a 40-GE interface as a single interface. To improve port density, reduce costs, and
improve network flexibility, you can also split a 40-GE interface into four 10-GE breakout interfaces.
For example, you can split 40-GE interface FortyGigE 1/0/1 into four 10-GE breakout interfaces
Ten-GigabitEthernet 1/0/1:1 through Ten-GigabitEthernet 1/0/1:4.
A 40-GE interface split into four 10-GE breakout interfaces must use a dedicated 1-to-4 cable. For
more information about the cable, see the installation guides.
The 10-GE breakout interfaces support the same configuration and attributes as common 10-GE
interfaces, except that they are numbered in a different way.
After the
using tengige
command is successfully configured, you can view the four 10-GE breakout
interfaces by using the
display interface brief
command.

using tengige
By default, a 40-GE interface is not
split and operates as a single
interface.
Combining four 10-GE breakout interfaces into a 40-GE interface
As a best practice for the long-term system stabilization, reboot the device after configuration.
If you need higher bandwidth on a single interface, you can combine the four 10-GE breakout
interfaces into a 40-GE interface.
After you combine the four 10-GE breakout interfaces, replace the dedicated 1-to-4 cable with a
dedicated 1-to-1 cable or a 40-GE transceiver module. For more information about the cable or
transceiver module, see the installation guides.
After the
using fortygige
command is successfully configured, you can view the 40-GE interface by
using the

command.
