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 1/0/1 into four 10-GE interfaces
Ten-GigabitEthernet 1/0/1:1 through Ten-GigabitEthernet 1/0/1:4.
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.
interface interface-type
interface-number
N/A
3. Split the 40-GE interface into
four 10-GE interfaces.
using tengige
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 or a 1-to-4
fiber and transceiver modules.
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.
To combine four 10-GE interfaces into a 40-GE interface:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter the view of any 10-GE
interface split from a 40-GE
interface.
