Splitting A 40-Ge Interface And Combining 10-Ge Breakout Interfaces - HP FlexFabric 12900 Series Configuration Manual

Splitting a 40-GE interface and combining 10-GE breakout
interfaces
This feature is not supported on non-default MDCs.
Splitting a 40-GE interface into four 10-GE breakout interfaces
IMPORTANT:
Before you restart a switch configured with the using tengige command, save the splitting configuration
on the switch even if the switch is an IRF member switch. Otherwise, the splitting configuration cannot take
effect.
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 a 40-GE interface FortyGigE 1/0/16 into four 10-GE breakout interfaces
Ten-GigabitEthernet 1/0/16:1 through Ten-GigabitEthernet 1/0/16:4.
If an HP 12910 switch with an LSX1FAB10A1 module or an HP 12916 switch with an LSX1FAB16S1
module uses the LSX1QGS16EA1 board, you can split up to twelve of the sixteen 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 breakout interfaces.
If an HP 12910 switch with an LSX1FAB10A1 module or an HP 12916 switch with an LSX1FAB16S1
module uses the LSXM1QGS24EX1 board, you can split up to eight of the twenty-four 40-GE QSFP+
interfaces on the board. The 24 interfaces are divided into two groups by their numbers. Interfaces
numbered 1 through 12 belong to one group, and interfaces numbered 13 through 24 belong the other
group. You can split 4 of the 12 interfaces in each group into 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.

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