License

The switch provides the license file loading and license status display functions.

Context

You need to activate licenses in either of the following situations: 1. Apply for and purchase the license to obtain authorization of corresponding functions when purchasing a new device. 2. Re-apply for, upgrade, and activate a license file to obtain new functions and resources due to service development although the license file has been activated on the device.

Loading license from a server is applicable to the batch loading scenario. To use this method, name the license file in format ESN.dat (for example, if the ESN is 21980107511234567890, the license file name is 21980107511234567890.dat) and upload the file to the server.

Procedure

Choose Maintenance > System Maintenance > License to open the License page.

Table 1 describes parameters on the page.
