Hi, Stanislav!
If the VRRP protocol is used, the number of licenses depends on the number of licenses. With respect to hsb, I think you're probably talking about stacking, and if you're configuring stacking, the number is as follows:
How many APs can be connected to a stack?
Assume that switch A can connect to 32 APs and switch B can connect to 64 APs. After switch A and switch B are combined into a stack, how many APs can connect to the stack?
Principle: After switch A and switch B are combined into a stack, the stack license of the master switch prevails.
If switch A functions as the master switch in a stack, the number of APs that can connect to the stack is 32.
If switch B functions as the master switch in a stack, 64 APs can be connected to the stack.
After an active/standby switchover, if the license containing the ESNs of switch A and switch B is not loaded in time, the number of APs that can connect to the stack is restored to the default value 16.
The license control items of the active and standby switches are different. The standby switch synchronizes the license of the active switch. The license of the active switch does not contain the ESN of the standby switch. Therefore, the license status of the standby switch changes to Trial. After the active/standby switchover, the license status of the stack system changes to Trial. A license in Trial state has a 60-day trial period. After the license trial period expires, the maximum number of APs that can access the stack is restored to the default value 16.
