How to Install a License for a Stack System of S5700
Obtaining Licenses for a Stack System
Figure 1-1 shows the license application process. You need to apply for a license on the Electronic Software Delivery Platform (ESDP) at http://app.huawei.com/isdp. For the license control items supported by S5700 switches, see "License Control Items" in the S5700 Series Switches License Usage Guide.
Different from the license for a standalone switch, a stack license must contain license control items for all stack members. To be more specific:
- When obtaining device ESNs, you need to obtain ESNs of all stack members.
- When activating and obtaining licenses, you need to enter the ESNs and entitlement IDs or activation passwords of all stack members on the ESDP.
Installing Licenses for a Stack System
To install a license for a stack system, activate the license file in the stack system.
- Upload the .dat license file to the master switch in the stack system.The following example describes how to upload a license file to an S5731-H switch using FTP.

The standby and slave switches of the stack system will synchronize the license file from the master switch. If the license file fails to be activated, rectify the fault based on the error message. For details, see Table 1-1.

Installing Licenses After Standalone Switches Are Added to a Stack System
What Can I Do If No License Is Installed on Standalone Switches Before They Are Added to a Stack
After standalone switches are added to a stack system, apply for a license file that contains the ESNs of all member switches, and install the license file in the stack system.
What Can I Do If Licenses Have Been Installed on Standalone Switches Before They Are Added to a Stack
To ensure that the stack license can be used normally after standalone switches are added to the stack, you are advised to apply for a license file that contains ESNs of all stack members before the 60-day trial period of the stack license ends. Otherwise, according to How Does a Stack License Takes Effect, the stack license will become invalid when the trial period ends, affecting service functions of the stack.
Before installing a new license file, run the license revoke command to revoke the original license file.
How Does a Stack License Takes Effect
- The license status of a stack is determined by that of the master switch.
- After a master/standby switchover, the license status of the stack is determined by that of the new master switch. The license status of the standby and slave switches is determined by the device version, license control items, and ESN, as shown in Table 1-2 and Table 1-3.

No
- The licenses of the standby and slave switches change to the trial state.
- The stack license changes to the trial state.
The standby and slave switches synchronize the license file of the master switch regardless of whether they have the same license-controlled items as the master switch. In this situation, since the license file of the master switch does not contain the ESNs of the standby and slave switches, the licenses of the standby and slave switches change to the trial state after a master/slave switchover.

- The licenses of the standby and slave switches are in normal state.
- The stack license is in normal state.
The standby and slave switches synchronize the license file of the master switch regardless of whether they have the same license-controlled items as the master switch. In this situation, since the license file of the master switch contains the ESNs of the standby and slave switches, the licenses of the standby and slave switches are still effective after a master/slave switchover.

- The licenses of the standby and slave switches change to the trial state.
- The stack license changes to the trial state.
Since the license files of the standby and slave switches have different license-controlled items from that of the master switch, the standby and slave switches synchronize the license file of the master switch. However, the license file of the master switch does not contain the ESNs of the standby and slave switches. In this situation, the licenses of the standby and slave switches change to the trial state after a master/slave switchover.

No
- The licenses of the standby and slave switches are in normal state.
- The stack license is in normal state.
Since the license files of the standby and slave switches have the same license-controlled items as that of the master switch, the standby and slave switches use their own license files and do not synchronize the license file of the master switch.

- The licenses of the standby and slave switches are in normal state.
- The stack license is in normal state.
Since the license files of the standby and slave switches have different license-controlled items from that of the master switch, the standby and slave switches synchronize the license file of the master switch, which contains the ESNs of the standby and slave switches. As such, the licenses of the standby and slave switches are still effective after a master/standby switchover.
FAQs
FAQ 1: How Many APs Can a Stack System Manage
Assume that switch A has a license that contains only its own ESN and can manage up to 32 APs, and switch B has a license that contains only its own ESN and can manage up to 64 APs.
How many APs can be managed by the stack set up by switches A and B?
Explanation:
According to How Does a Stack License Takes Effect:
- The number of APs that can be managed by a stack system is determined by the license of the master switch.
- Since switches A and B have different license-controlled items in their license files, the standby switch synchronizes the license file from the master switch.
- Since neither the license file of switch A nor switch B has the ESNs of the two switches, the license of the standby switch is in the trial state. After a master/standby switchover, the stack license changes to the trial state.
Based on the preceding principles, the number of APs that can be managed by the stack system varies according to the following situations:
- If switch A is the master switch, the stack system can manage a maximum of 32 APs. After a master/standby switchover, the stack license enters a 60-day trial period. During this period, the stack system can still manage up to 32 APs. After the trial period expires, the maximum number of APs that can be managed by the stack system changes to the default value (that is, 16).
- If switch B is the master switch, the stack system can manage a maximum of 64 APs. After a master/standby switchover, the stack license enters a 60-day trial period. During this period, the stack system can still manage up to 64 APs. After the trial period expires, the maximum number of APs that can be managed by the stack system changes to the default value (that is, 16).
FAQ 2: Does a Stack System Support the Enhanced VXLAN Function?
Assume that switch A has a license that contains its own ESN and has the license-controlled item for enhanced VXLAN, and switch B has a license that contains its own ESN and does not contain the license-controlled item for enhanced VXLAN.
Does the stack system set up by switches A and B support the enhanced VXLAN function?
Explanation:
According to How Does a Stack License Takes Effect:
- Whether a stack system supports the enhanced VXLAN function is determined by the license of the master switch.
- Since switches A and B have different license-controlled items in their license files, the standby switch synchronizes the license file from the master switch.
- Since neither the license file of switch A nor switch B has the ESNs of the two switches, the license of the standby switch is in the trial state. After a master/standby switchover, the stack license changes to the trial state.
Based on the preceding principles, whether the stack system supports the enhanced VXLAN function varies according to the following situations:
- If switch A is the master switch, the stack system supports the enhanced VXLAN function. After a master/standby switchover, the stack license enters a 60-day trial period. During this period, the stack system still supports the enhanced VXLAN function. After the trial period expires, the stack system does not support the enhanced VXLAN function.
- If switch B is the master switch, the stack system does not support the enhanced VXLAN function. After a master/standby switchover, the stack still does not support the enhanced VXLAN function.
