ClearPass Policy Visualiser (CPV), available from my GitHub repository, is a dependency analysis and policy impact exploration platform for HPE Aruba Networking ClearPass Policy Manager.

CPV provides an interactive view of the relationships between Services, Role Mapping Policies, Enforcement Policies, Enforcement Profiles, Roles, and Enforcement Attributes. It helps administrators trace dependencies, understand policy logic, identify unused objects, and assess how configuration changes may impact authentication, authorisation, and enforcement workflows.

What’s new in version 1.7.0

Most organisations run more than one ClearPass. Version 1.7.0 lets a single CPV instance manage up to three ClearPass environments, such as Production, Test and Dev:

• Multiple ClearPass environments, each with its own REST API, RADIUS and PostgreSQL settings, cached data and sign-in
• Environment selector in the navbar, with an optional red PRODUCTION badge
• Environments page to add, edit and remove environments from the browser, with connection testing before saving and optional assisted provisioning of ClearPass objects
• Edit the initial environment’s settings without editing files or restarting
• Clearer connection diagnostics that explain why a check failed, such as DNS, a blocked port, a wrong API path or a rejected PostgreSQL password
• RADIUS check that confirms the server is reachable and the shared secret matches
• The active environment shown on every page, in the logs, in PDF reports and in exported file name

These build on earlier releases: 1.6.x added Docker-based deployment, direct PostgreSQL endpoint profiling and Service Hit Counts and 1.5.2 added dashboard lookups and read-only Impact Analysis.

By consolidating policy relationships and dependencies into one interface, ClearPass Policy Visualiser supports troubleshooting, change planning, configuration review, cleanup and operational documentation.

This technote covers how to configure ClearPass API access, then provides step-by-step guidance for installing, configuring and using ClearPass Policy Visualiser, including managing multiple environments.

It also includes Appendix A: Large-Scale ClearPass Deployment Validation, which documents validation testing performed against a large ClearPass environment.
