What is the maximum number of internal captive portal based SSID's that can be configured on an IAP ?
The maximum number of internal captive portal based SSID's that can be configured on IAP is 1.
IAP uses one global ICP (internal captive portal) profile.
Eg: CP based SSID is referred to as Guest SSID.
We can configure captive portal in internal-acknowledged or Internal-authenticated format. Lets assume we create the following two SSID's:
SSID 1: Internal-Acknowledged
SSID 2: Internal -Authenticated
In the above case SSID 1 was created before SSID 2. As soon as SSID 2 will get created, it will trigger SSID 1 to change to Internal-Authenticated as well.
Basically we can not have 2 SSID's using different Internal CP methods.
Note: This applies to all versions.
