Splitting a 40-GE interface and combining 10-GE breakout
interfaces
Splitting a 40-GE QSFP+ interface into four 10-GE breakout interfaces
You can use a 40-GE QSFP+ interface as a single interface. To improve port density, reduce costs, and
improve network flexibility, you can also split a 40-GE QSFP+ interface into four 10-GE breakout
interfaces.
After the using tengige command is successfully configured, reboot your device as needed. For more
information, see Layer 2—LAN Switching Command Reference.
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.

using tengige
By default, a 40-GE interface is not
split and operates as a single
interface.
The 10-GE breakout interfaces split
from a 40-GE interface support the
same configuration and attributes as
common 10-GE interfaces, except
that they are numbered in a different
way.
Combining four 10-GE breakout interfaces into a 40-GE interface
If you need higher bandwidth, you can combine the four 10-GE breakout interfaces into a 40-GE
interface.
After the using fortygige command is successfully configured, reboot your device as needed. For more
information, see Layer 2—LAN Switching Command Reference.
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.
