Splitting a 40-GE interface and combining split 10-GE
interfaces
This feature is not supported on non-default MDCs.
Splitting a 40-GE interface into four 10-GE interfaces
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 interfaces.
For example, you can split a 40-GE interface FortyGigE 1/0/16 into four 10-GE interfaces
Ten-GigabitEthernet 1/0/16:1 through Ten-GigabitEthernet 1/0/16:4.
If an H3C S12510-X switch with an LSX1FAB10A1 module or an H3C S12516-X switch with an
LSX1FAB16S1 module uses the LSX1QGS16EA1 board, you can split up to 12 of the 16 40-GE QSFP+
interfaces on the board.
The 16 interfaces are divided into two groups by their numbers. Interfaces numbered 1 through 8
belong to one group, and interfaces numbered 9 through 16 belong the other group. You can split 6 of
the 8 interfaces in each group into 10-GE interfaces.
To split a 40-GE interface into four 10-GE interfaces:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter 40-GE interface view.

3. Split the 40-GE interface into
four 10-GE interfaces.

By default, a 40-GE interface is not
split and operates as a single
interface.
• The 10-GE interfaces split from a
40-GE interface support the same
configuration and attributes as
common 10-GE interfaces, except
that they are numbered
differently.
• A 40-GE interface split into four
10-GE interfaces must use a
dedicated 1-to-4 cable.
4. Reboot the card that houses
the interface.
N/A
After creating the four 10-GE
interfaces, the system removes the
40-GE interface.
Combining four split 10-GE interfaces into a 40-GE interface
If you need higher bandwidth, you can combine the four split 10-GE interfaces into a 40-GE interface.
