1x100GE Breakout
You can configure breakout on a 400GE port for use the QSFP-28 transceiver module in a 1x100G mode. This feature is supported
on Cisco ASR 9900 5th Generation 4Tb line cards (A99-10X400GE-X-SE/TR). As part of this enhancement, 400GE ports support these
QSFP28 optics:
-
QSFP-100G-SR4-S
-
QSFP-100G-PSM4-S
-
QSFP-100G-CWDM4-S
-
QSFP-100G-FR-S
-
QSFP-100G-LR4-S
-
QSFP-100G-ER4L-S
-
QSFP-40/100-SRBD
-
QSFP-100G-SM-SR
-
QSFP-100G-LR-S
This task enables you to configure the breakout option:
RP/0/RSP0/CPU0:router# configure
RP/0/RSP0/CPU0:router(config)# hw-module location 0/2/CPU0 port 1 breakout 1xHundredGige
Here's the show command output indicating the breakout configuration:

4x100GE Breakout
The QSFP-DD modules support 400Gbps. You can configure 4x100G breakout on a QSFP-DD port and use it as four individual 100G
interfaces.
This feature is supported on the following variant of Cisco ASR 9000 Series Line Cards:
-
A99-10X400GE-X-SE
-
A99-10X400GE-X-TR
-
A9K-20HG-FLEX-SE
-
A9K-20HG-FLEX-TR
-
A9K-8HG-FLEX-SE
-
A9K-8HG-FLEX-TR
This example shows how to enable 4x100GE breakout:
RP/0/RSP0/CPU0:router(config)# hw-module location 0/8/CPU0 port 0 breakout 4xHundredGigE
The following output shows the breakout configuration:
