Splitting a 40-GE interface and combining 10-GE breakout
interfaces
IMPORTANT:
•
This feature is not supported on non-default MDCs.
•
This feature is not supported on 40-GE interfaces on LSQM1SRP8X2QE0 MPUs.
•
On an LSQM1QGS24RSG0 module, this feature is supported on interfaces 1 through 16.
Splitting a 40-GE interface into four 10-GE breakout interfaces
IMPORTANT:
For this configuration to survive a reboot, save the configuration before rebooting the switch.
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.
A 40-GE interface split into four 10-GE breakout interfaces must use a dedicated 1-to-4 cable. For
more information about the cable, see the installation guide.
After you configure this feature on a 40-GE interface on an interface card, reboot the interface card to
make the configuration take effect. Do not assign the changed interfaces to any non-default MDC
before rebooting the interface card.

split and operates as a single
interface.
