Configuring common Ethernet interface settings
This section describes the settings common to Layer 2 Ethernet interfaces, Layer 3 Ethernet
interfaces, and Layer 3 Ethernet subinterfaces. For more information about the settings specific to
Layer 2 Ethernet interfaces, see "Configuring a Layer 2 Ethernet interface." F
or more information
about the settings specific to Layer 3 Ethernet interfaces or subinterfaces, see "Configuring a Layer
3 Ethernet int

Splitting a 40-GE interface and combining 10-GE breakout
interfaces
About 40-GE interface splitting and 10-GE breakout interface combining
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.
The 10-GE breakout interfaces support the same configuration and attributes as common 10-GE
interfaces, except that they are numbered differently.
For example, you can split 40-GE interface FortyGigE 1/0/1 into four 10-GE breakout interfaces
Ten-GigabitEthernet 1/0/1:1 through Ten-GigabitEthernet 1/0/1:4.
If you need higher bandwidth on a single interface, you can combine the four 10-GE breakout
interfaces into a 40-GE interface.
Restrictions and guidelines for 40-GE interface splitting and 10-GE breakout interface
combining
• A 40-GE interface split into four 10-GE breakout interfaces must use a dedicated 1-to-4 cable.
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.
• Device reboot is not required for this feature to take effect. You can view the split or combined
interface by using the
display interface brief command.
• When the LSWM18QC interface module is installed in the slot 2 on the S9850-4C switch, the
interface numbered 8 on the interface module cannot be split.
• When the LSWM124TG2H, LSWM124XG2Q, LSWM124XGT2Q, LSWM124XG2QFC,
LSWM124XG2QL interface module is installed in the slot 2 on the S9850-4C switch, the
interface numbered 25 on the interface module cannot be split.
• All interfaces on the LSWM116Q interface module cannot be split.
• An interface with any of the following configurations cannot be split:
{ IRF physical interface.
{ Service loopback group member.
{ Reflector port for mirroring.
{ Forcibly bringing up a fiber port.
