Before creating a session, the ASR 5000 interacts with the SP Wi-Fi Service Manager for Cisco Prime over the Gx interface to retrieve the policy that needs to be applied on the session. This functionality is available in the SP Wi-Fi Service Manager for Cisco Prime Base Package; however, an add-on license is required to enable the ASR 5000 integration functionality.
Q. What is (optional) Wi-Fi Federation?
A. Wi-Fi users often travel with their devices, whether laptops, tablets, or smartphones. Service providers can facilitate roaming users gaining access to their network while traveling by allowing roamers to log in using their home operator credentials and subscription information without requiring users to register a new account and/or enter payment information. The SP Wi-Fi Service Manager for Cisco Prime Subscriber Services Portal helps enable the user to select his or her home service provider from a pull-down list of partners during initial login to the visited network. SP Wi-Fi Service Manager then proxies the login request to the home service provider. Once successfully authenticated, SP Wi-Fi Service Manager can cache the roaming user for a predetermined time for subsequent automatic login to the network based on visited service provider policies. Accounting records may also be captured and proxied to the home service provider for roaming settlement. This functionality is available in the SP Wi-Fi Service Manager for Cisco Prime Base Package; however, an add-on license is required to enable it.
Q. Does the SP Wi-Fi Service Manager for Cisco Prime include a customer-facing portal?
A. Yes, a portal is included as part of the SP Wi-Fi Service Manager for Cisco Prime.
