Adding ClearPass to the Controller Server List
Now that we’ve prepared for ClearPass integration, let’s dive into the process of adding ClearPass to the controller server list. This crucial step enables seamless communication between your Aruba controller and the ClearPass server.
A. Accessing the Aruba controller interface
To begin, log in to your Aruba controller’s web interface using your administrator credentials. Ensure you have the necessary permissions to modify server configurations.
B. Navigating to the server configuration section
Once logged in, follow these steps to reach the server configuration area:
- Click on “Configuration” in the main menu
- Select “Authentication” from the dropdown
- Choose “Servers” from the left-hand sidebar
- Click on “RADIUS Server” to access the RADIUS server list
C. Inputting ClearPass server details
Now, let’s add the ClearPass server to the RADIUS server list:
- Click “Add” to create a new RADIUS server entry
- Enter the following details:
- Server Name: Choose a descriptive name (e.g., “ClearPass-Primary”)
- IP Address: Input the ClearPass server’s IP address
- Auth Port: Typically 1812 (default RADIUS authentication port)
- Acct Port: Usually 1813 (default RADIUS accounting port)
- Shared Secret: Enter the pre-shared key configured on ClearPass
D. Configuring authentication parameters
Configure additional authentication settings to optimize ClearPass integration:
| Parameter | Recommended Setting |
|---|---|
| Retransmits | 3 |
| Timeout | 5 seconds |
| NAS Identifier | Controller’s hostname |
| NAS IP Address | Controller’s management IP |
E. Verifying server connectivity
After adding the ClearPass server, it’s crucial to verify connectivity:
- Click on the “Test Server” button next to the newly added ClearPass entry
- Check the response time and status
- If successful, you’ll see a “Server is responding” message
With ClearPass now added to the controller server list, we’re ready to move on to configuring ClearPass policies on the controller.
Configuring ClearPass Policies on the Controller
Now that we have added ClearPass to the controller server list, it’s time to configure the policies that will govern network access and security. This step is crucial for ensuring that your network resources are protected and users have appropriate access levels.
Creating role-based access control policies
Role-based access control (RBAC) is essential for managing user privileges effectively. Here’s a simple table outlining common roles and their typical access levels:
| Role | Access Level | Example Permissions |
|---|---|---|
| Admin | Full | Network configuration, user management |
| IT Staff | High | Troubleshooting, limited configuration |
| Employee | Medium | Internal resources, internet access |
| Guest | Low | Internet access only |
Setting up authentication methods
ClearPass supports various authentication methods to accommodate different security requirements:
- 802.1X
- MAC authentication
- Captive portal
Defining authorization rules
Authorization rules determine what resources users can access based on their authentication status and role. Key considerations include:
- Network segmentation
- Time-based access restrictions
- Device posture checks
Implementing accounting settings
Proper accounting settings are crucial for maintaining security and compliance. Configure ClearPass to log:
- User login/logout times
- Bandwidth usage
- Access attempts (successful and failed)
By carefully configuring these policies, you’ll create a robust security framework that balances user access with network protection. Next, we’ll explore how to test and troubleshoot your ClearPass implementation to ensure everything is working as expected.
Testing and Troubleshooting
Verifying ClearPass Integration
Now that we’ve configured ClearPass policies on the controller, it’s crucial to verify the integration and ensure everything is working smoothly. Start by checking the controller’s configuration to confirm that ClearPass is listed as an authentication server. Then, verify the connectivity between the controller and ClearPass using ping tests and checking server status.
Conducting Test Authentications
To thoroughly test the ClearPass integration, perform the following authentication tests:
- Wireless client authentication
- Wired client authentication
- VPN user authentication
- Guest user authentication
| Test Type | Expected Outcome | Troubleshooting Steps |
|---|---|---|
| Wireless | Successful connection and policy application | Check SSID settings, RADIUS server configuration |
| Wired | Port authentication and correct VLAN assignment | Verify switch port settings, RADIUS attributes |
| VPN | Secure tunnel establishment and proper access rights | Review VPN server config, ClearPass policy |
| Guest | Captive portal redirection and limited access | Check captive portal settings, guest policy |
Monitoring Logs and Reports
Regularly monitor ClearPass and controller logs to identify any authentication issues or policy violations. Key areas to focus on include:
- Authentication success and failure rates
- Policy enforcement logs
- RADIUS accounting data
- Device profiling information
Common Issues and Their Solutions
- Authentication Failures: Verify RADIUS shared secret, check certificate validity
- Policy Mismatch: Review role mapping and enforcement profiles
- Device Profiling Errors: Update device fingerprinting database, check profiling rules
- Performance Issues: Optimize ClearPass resources, load balance if necessary
By following these testing and troubleshooting steps, you can ensure a robust and reliable ClearPass integration with your Aruba controller.
Optimizing ClearPass Performance
Now that you have successfully integrated ClearPass with your Aruba controller, it’s time to focus on optimizing its performance. By fine-tuning server settings, implementing load balancing, and scheduling regular maintenance, you can ensure that your ClearPass deployment operates at peak efficiency.
