By default, a 100-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.
Restrictions and guidelines
This feature is supported only on the LSUM1CGS8QSSH0LSUM2CQGS12SG0 and
LSUM1CQGS32SF0 interface modules.
On the LSUM1CGS8QSSH0 interface modules, only 40-GE interfaces numbered 1 through 4 and 13
through 16 can be changed to 100-GE interfaces when they operate in Layer 2 mode and are not
configured as IRF physical interfaces. After you change the interface type, only odd-numbered
interfaces (interfaces numbered 1, 3, 13, and 15) are available, and these interfaces do not support
40-GE transceiver modules. For more information about IRF physical interfaces, see IRF
configuration in
Virtual Technologies Configuration Guide
.
On the LSUM2CQGS12SG0 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 LSUM1CQGS32SF0
interface modules, after you change each group of 40-GE interfaces to 100-GE interfaces, only
interfaces of odd number are 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. For this
configuration to succeed on the LSUM1CQGS32SF0 interface modules, make sure all interfaces in
one group are specified in this configuration. Two continuous interfaces of odd number starting from
1 are organized into one group.
