Load a license for a stack of CE series switches

14

Load a license for a stack of CE series switches as follows:
1. Apply for a license and upload the license file to the master switch of the stack system.
A license is bound to the ESN of a physical device, and each stack member has an independent ESN. You can apply for a license for two switches in a stack or for each switch.
2. Run the license active file-name command in the user view to activate the uploaded license file.
- If there are two license files, run the license active file-name command twice and specify two different file names. The system will then find the matching ESNs to activate the license files.
- If there is only one license file, run the license active file-name command only once.

3. Run the display license command to check whether the license file has been successfully loaded.

If you load the licenses on two switches and then set up a stack system, the features activated for the stack are a combination of features activated for the two member switches. If a license is uploaded to only one of the two switches, the license is valid for the stack system.

If the stack system splits, the licenses loaded to the switches respectively take effect. In addition, the activated licensed features can still be used on the switches even if these features are not activated using the switches' own license.

Perform the following steps to load a license file to a stack system: 1. Apply for a license and upload the license file to the master switch of the stack system.

If there are multiple license files, run the license active file-name command multiple times and specify different file names each time. The system will then find the matching ESNs to activate the license files. ? If there is only one license file, run the license active file-name command only once. 3. Run the display license command to check whether the license file has been successfully loaded.

In addition, the activated licensed features can still be used on the switches even if these features are not activated using the switches' own license. If the license of Switch1 supports feature A and the license of Switch2 supports feature B, the two switches support features A and B after they set up a stack. If the stack breaks, feature B on Switch1 can still run even after Switch1 restarts but new configurations cannot be added to feature B.

How is a license loaded for SVF
When a license is loaded for SVF, you only need to load the license on the parent switch, not on the leaf switch. Perform the following operations: 1. Apply for a license and upload it to the parent switch. You only need to apply for a license for the parent switch, not for the leaf switch. If the parent switch is a standalone device, you can use its ESN to apply for a license. If the parent switch is a stack of two devices, you can apply for a common license with the ESNs of both devices, or apply for a license for each ESN. 2. Run the license active file-name command in the user view to activate the license file you uploaded. - If there are multiple license files, run the license active file-name command multiple times and specify different values for file-name. The system will then find the matching ESN to activate the license files. - If there is only one license file, run the license active file-name command only once. 3. Run the display license command to check whether a license file has been loaded.

For CE switches, should a license file be loaded before or after a stack is set up
You can load license files for switches before or after setting up a stack. The result is not affected by the operation sequence.
