View license status on S series switch

1

On an S series switch, except S1700, run the following commands to view license information:
Run the display license command to view the license file information.
A switch can have only one activated license file. Run this command to view detailed information about the activated license in the system, including license file name, version, validity period, and configuration.

Run the display license state command to view the license status on the MPU (modular switch) or switch (fixed switch) and number of remaining validity days.
The system supports the following license states:
Normal: The license is in active state.
- Demo: The license is in demo state.
- Trial: The license has expired but still valid during the trial period.
Emergency: The license is in emergency state.
Default: No license file needs to be activated or the license file has expired.
Note: The preceding command displays information only when the switch has activated license file. If the switch does not have an activated license file, no information is displayed.

Run the display license resource usage command to display the usage of the resource items defined in a license file.
Resource usage refers to the percentage of resources used out of resources defined by the license file.

Enable and disable PoE on an S series switch
Enable or disable the PoE function on S series switches:

1. By default, the PoE function is enabled on an interface
2. Enable or disable PoE power supply.
<HUAWEI>system-view
[HUAWEI]interface gigabitethernet 1/0/0
[HUAWEI-GigabitEthernet1/0/0]undo poe enable  //Disable PoE power supply.
[HUAWEI-GigabitEthernet1/0/0]poe enable       //Enable PoE power supply.

The downlink electrical interfaces of PoE switches support PoE power supply, with up to 30 W power on each interface. The maximum power supply distance is 100 m.
Only ES0D0G48VA00 (S7700)/LE0DG48VEA00 (S9300) cards of modular switches (S7700/S9700/S9300/S12700) support PoE power supply.

If the switch connects to 48 V standard PoE powered devices but cannot negotiate power supply capabilities with the devices, you can run poe force-power on the interfaces to forcibly power on the devices.
