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, the system prompts you to reboot your device. You must reboot the device and then the system deletes the 40-GE interface and creates four 10-GE breakout interfaces.
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.
To split a 40-GE interface into four 10-GE breakout interfaces:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter 40-GE interface view. | interface interface-type interface-number | N/A |
3. Split the 40-GE interface into four 10-GE breakout interfaces. | 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, the system prompts you to reboot your device. You must reboot the device and then the system deletes the four 10-GE breakout interfaces and creates the combined 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.
To combine four 10-GE breakout interfaces into a 40-GE interface:
