HP HPE7-A02 Exam With Confidence Using Practice Dumps

To support the requirement for HPE Aruba Networking ClearPass Policy Manager (CPPM) to have HTTP User-Agent strings for profiling devices, you should add the CPPM server's IP address to the IP helper list in all client VLANs on routing switches. This configuration ensures that DHCP requests and other relevant client traffic are forwarded to CPPM, allowing it to capture HTTP User-Agent strings and use them for device profiling.

1.IP Helper Configuration: Adding CPPM to the IP helper list ensures that the switch forwards DHCP and other client traffic to CPPM, enabling it to gather necessary information for profiling.

2.User-Agent Strings: By receiving client traffic, CPPM can analyze HTTP headers and capture User-Agent strings, which provide valuable information about the client's device and browser.

3.Profiling Support: This approach supports the comprehensive profiling of devices, allowing CPPM to apply appropriate policies based on detailed device information.

To ensure that the correct profiles apply after client attributes are updated based on Syslog messages, you should tune the Change of Authorization (CoA) delay on the ClearPass servers to a value of 5 seconds or greater. This delay allows sufficient time for the attribute updates to be processed and for the reauthentication to occur correctly, ensuring that the updated profiles are accurately applied to the clients.

1.CoA Delay: Adjusting the CoA delay ensures that the system has enough time to update client attributes and reauthenticate them properly before applying new profiles.

2.Profile Accuracy: This delay helps in preventing premature reauthentication and ensures that the most recent attribute updates are considered when applying profiles.

3.System Synchronization: Ensures synchronization between the attribute update and the reauthentication process.

Comprehensive Detailed Explanation

In a user-based tunneling (UBT) setup with reserved VLAN mode, VLAN 64 is used for routing traffic at the gateways. Since the IoT traffic is tunneled to the AOS-10 gateway:

On the gateways:

VLAN 64 must be configured in the iot-wired role for routing purposes.

On the switches:

VLAN 64 does not need to be configured on the access switch physical uplinks because the IoT traffic is tunneled directly to the gateway and does not rely on VLAN configurations at the access layer switches.

Reserved VLAN mode:

Ensures that traffic is encapsulated within the UBT tunnel, and VLANs like 64 are only relevant at the gateway for routing and enforcement.

Therefore, the correct configuration is to define VLAN 64 in the iot-wired role on the AOS-10 gateways and not on any physical interfaces.
