This article describes the installation and configuration steps for Aruba Instant IAP. Our test was performed with Aruba AP-303-RW.

Connect to the Master IP address, login with AP admin and pass ( admin / admin) and type these commands:

configure terminal
wlan ssid-profileĀ <type SSID name>
auth-pkt-mac-format delimiter –
end
commit apply


To add domains to walled garden, type these commands:

configure terminal

white-list <cdn.wifihotspot.io>
white-list <starthotspot.com>
white-list <cdnhotspot.azureedge.net>

white-list <13.90.247.200>
