Splitting A 40-Ge Interface And Combining 10-Ge Breakout Interfaces - H3C S5830V2 series Configuration Manual

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.
To split a 40-GE interface into four 10-GE breakout interfaces:
Step
1. Enter system view.
2. Enter 40-GE interface view.
3. Split the 40-GE interface into
four 10-GE breakout
interfaces.
4. Reboot the device.
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.
To combine four 10-GE breakout interfaces into a 40-GE interface:
Step
1. Enter system view.
2. Enter the view of any 10-GE
breakout interface split from a
40-GE interface.
3. Combine the four 10-GE
breakout interfaces into a
40-GE interface.

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.
After creating the four 10-GE
breakout interfaces, the system
removes the 40-GE interface.
A 40-GE interface split into four
10-GE breakout interfaces must use a
dedicated 1-to-4 cable.
