ER7212, SDN Software Controller bug in Voucher mgmt?
I seem to be encountering an issue with Voucher based guest access when using the ER7212PC embedded SDN controller.
The use case I am trying to implement is to have one voucher available to use for a certain number of simultaneous guests (lets say 50 simultaneous guests) OR a certain number of total uses of the vouchers (for example 50 uses of the voucher). The authorization for each guest should expire after a defined time period (for example 8 hours after they first use the voucher).
Now it looks like this should be possible through the Hotspot voucher config. However the behavior I am seeing is that when the first user's authorization expires, the voucher also expires even though the voucher's use limit or the voucher's simultaneous user limit has not been reached.
Below is an example of a voucher I created. The voucher was configured so that it can be used 999 times before it expires. Users / Client duration was set to 1 hour (for testing). So the assumption is that client using the voucher should expire after 1 hour, but the voucher itself should stay valid until it has been used 999 times.
However as you can see from the attached screenshots, even though only ONE client used the voucher ONCE, an hour later both the the client and the voucher expired. So voucher could only be utilized once.
How do I work around this issue? Is this a bug in the current SDN controller version on the ER7212 (i have the latest ER7212 firmware). Or am I missing some other configuration?
