License Installation: How Do I Install a License File for a Stack System?
Perform the following steps to install a license file to a stack system.
- Apply for a license using the ESNs of member switches.
- Run the display license esn command to obtain the ESNs of stack member switches.
- Use the ESNs to apply for a license file.
For details about how to apply for a license, see Obtaining Licenses in the S1720, S5700, and S6700 Series Switches License Usage Guide.
In V200R009 and later versions, if all member switches have installed license files with the same license-controlled items before they set up a stack, you do not need to apply for a new license for the stack. If only some of member switches have installed a license file, apply for a new license for the stack.
In versions prior to V200R009, apply for a license that contains ESNs of all the member switches.
- Install the license file to the stack master switch.
- Run the license active command to activate the license file. The standby and slave switches will synchronize the license from the master switch.
- After the license file is installed successfully, run the display license command to check license file information.
After the stack splits, the license is still effective on all the member switches.
You must have a Huawei account to log in to the license self-service system. For details on how to apply for a Huawei account, click Help, and then click Applying for an Account under the Basic Concepts node.
If member switches are running a version prior to V200R009, you must apply for a license that contains ESNs of all member switches. If the license file contains only the ESN of the master switch, the license is in normal state and the license-controlled features can take effect in the stack. If a switchover occurs in the stack, however, the license will change to the trial state (60-day trial period). If the license file contains only the ESN of the standby switch or a slave switch, the license remains in trial state after it is loaded.
- If member switches are running V200R009 or a later version, you can apply for a license that contains ESNs of all member switches, or apply a license for each ESN and load the licenses to the switches before setting up a stack. When using the second method, ensure that all license files have the same license-controlled items, because:
- If the license files of the standby and slave switches have the same items as the license file of the master switch, the standby and slave switches use their own license files and do not synchronize the license file from the master switch. Their license files are still effective after a switchover in the stack.
- If the license files of the standby and slave switches have different items than the license file of the master switch, the standby and slave switches synchronize the license file from the master switch. If the license file of the master switch contains the ESNs of the standby and slave switches, the license is in normal state on the standby and slave switches and will still effective after a switchover. If the license file on the master switch does not contain the ESNs of the standby and slave switches, the license will change to trial state (60-day trial period) on the standby and slave switches, because ESN in the synchronized license file is different from the ESN of the local switch. After a switchover, the license of the stack will also change to trial state.
