Splitting a 100-GE interface and combining 10-GE breakout
interfaces
About 100-GE interface splitting and 10-GE breakout interface combining
You can use a 100-GE interface as a single interface. To improve port density, reduce costs, and
improve network flexibility, you can split a 100-GE interface with a split-capable transceiver module
installed 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 100-GE interface HundredGigE 1/0/1 into four 10-GE breakout interfaces
Ten-GigabitEthernet1/0/1:1 through Ten-GigabitEthernet1/0/1:4.
If you need higher bandwidth on a single interface, you can combine the multiple 10-GE breakout
interfaces into a 100-GE interface.
Restrictions and guidelines for 100-GE interface splitting and 10-GE breakout interface
combining
A 100-GE interface split into multiple 10-GE breakout interfaces must use a dedicated cable. After
you combine the multiple 10-GE breakout interfaces, replace the dedicated cable with a dedicated
1-to-1 cable or a 100-GE transceiver module. For more information about the cable or transceiver
module, see the installation guides.
After configuring this feature, you do not need to reboot the device. To view information about the
breakout interfaces, execute the
display interface brief
command.
The interface numbered 31 on the S6850-56HF or S9850-32H switch cannot be split.
When the LSWM18CQ or LSWM18CQMSEC interface module is installed in the slot 2 on the
S9850-4C switch, the interface numbered 7 on the interface module cannot be split.
When the LSWM124TG2H interface module is installed in the slot 2 on the S9850-4C switch, the
interface numbered 25 on the 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.
