assign port-speed 100GE
Function
The assign port-speed 100GE command changes the maximum rate of QSPF28 interfaces to 100 Gbit/s.
The undo assign port-speed 100GE command restores the maximum rate of QSPF28 interfaces to 40 Gbit/s.
On the S6730-H24X6C (part number: 02352FSG) and S6730-H48X6C (part number: 02352FSF), the default rate of QSPF28 interfaces is 40 Gbit/s.
On the S6730-H24X6C (part number: 02353GFC), S6730S-H, and S6730-H48X6C (part number: 02353FWL), by default, the license has been loaded, and the rate of QSPF28 interfaces is 100 Gbit/s.
Only the S6730-H and S6730S-H supports this command.

Usage Guidelines
Usage Scenario
On the S6730-H24X6C (part number: 02352FSG) and S6730-H48X6C (part number: 02352FSF), the default rate of QSPF28 interfaces is 40 Gbit/s. To use QSPF28 interfaces as 100GE interfaces, contact the equipment supplier to apply for and purchase a license. After activating the license, run the assign port-speed 100GE command to change the maximum rate of QSPF28 interfaces to 100 Gbit/s. To change the maximum rate of QSPF28 interfaces from 100 Gbit/s to 40 Gbit/s, run the undo assign port-speed 100GE command. This command configuration takes effect only after the device is restarted.
On the S6730-H24X6C (part number: 02353GFC), S6730S-H and S6730-H48X6C (part number: 02353FWL), by default, the license has been loaded, and the rate of QSPF28 interfaces is 100 Gbit/s. To change the rate of QSPF28 interfaces from 100 Gbit/s to 40 Gbit/s, run the undo assign port-speed 100GE command and restart the device.
Precautions
- The corresponding license is required before this command is run.
- You can run the display device port-speed configuration command to check the current rate of an interface and the rate that takes effect after a device restart.
- After the device restarts, the original interface configuration may be lost. Therefore, back up the configuration before the restart. After the restart, check the configuration and modify it if necessary.
- After this command is executed, the maximum rate of QSPF28 interfaces is the configured rate if you restore the factory settings with one click.
- After the license expires, the maximum rate of QSPF28 interfaces is the default rate if you restore the factory settings with one click.
Example
# Change the maximum rate of all 40GE interfaces on the switch to 100 Gbit/s.
<HUAWEI> system-view [HUAWEI] assign port-speed 100ge all Warning: After you restart the device(s), the configuration of 100G interfaces may be lost. You need to back up the configuration be fore restarting the device(s), and check and modify the configuration after restart of the device(s). Continue? [Y/N]:y Info: The current configuration has been modified and takes effect after the device is restarted.
