📊 Cisco ISE Node Comparison

The first chart compares the roles and functions of different ISE nodes:
Primary Administration Node: Handles centralized management (mandatory, control plane).
Policy Service Node (PSN): Enforces runtime policies (mandatory, workhorse).
Monitoring and Troubleshooting Node: Collects logs and generates reports (mandatory, log collection).
pxGrid Node: Enables context sharing (optional, context sharing).
