End-User Guest and Sponsor Portals in Distributed Environment
Cisco ISE end-user web portals depend on the Administration, Policy Services, and Monitoring personas to provide configuration, session support, and reporting.
Policy Administration node (PAN): Configuration changes that you make to the users, devices, and end-user portals are written to the PAN.
Policy Service node (PSN): The end-user portals run on a PSN, which handles all session traffic, including: network access, client provisioning, guest services, posture, and profiling. If a PSN is part of a node group, and one node fails, the other nodes detect the failure and reset any pending sessions.
Monitoring node (MnT node): The MnT node collects, aggregates, and reports data about the end-user and device activity on the My Devices, Sponsor, and Guest portals. If the primary MnT node fails, the secondary MnT node automatically becomes the primary MonT node.
