If you need higher bandwidth on a single interface, you can combine the four 10-GE breakout 
interfaces into a 40-GE interface. 

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 guide. 

After you configure this feature on a 10-GE breakout 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.

By default, a 40-GE interface is 
not split and operates as a single 
interface. 

 

Changing the interface type of 100-GE interfaces in batches 

 

IMPORTANT: 

  This feature is not supported on non-default MDCs. 

  The interfaces to be changed in batches must be on the same card or MPU. 

 

Restrictions and guidelines 

This feature is supported only on the LSQM1CQGS12SG0, LSQM1TGS24QSFD0, and 
LSQM1CTGS24QSFD0 interface modules. 

On the LSQM1CQGS12SG0 interface modules, after you change each group of 40-GE interfaces to 
100-GE interfaces, only interfaces 1, 4, 7, and 10 are available. On the LSQM1TGS24QSFD0 and 
LSQM1CTGS24QSFD0 interface modules, after you change each group of 40-GE interfaces to 
100-GE interfaces, only interface 25 is available. 

Reboot the interface module after you configure this feature. Do not assign the changed interfaces to 
any non-default MDC before rebooting the interface module. 

For this configuration to survive a reboot, save the running configuration before rebooting the device. 

Changing 100-GE interfaces to 40-GE interfaces in batches 

To improve network flexibility, you can change 100-GE interfaces to 40-GE interfaces in batches. For 
this configuration to succeed, you must specify the available interface numbers. 

To change 100-GE interfaces to 40-GE interfaces in batches:
