When using HPE Aruba Networking ClearPass Device Insight (CPDI) and you need to reclassify a device to a custom type and apply this classification to all devices with similar attributes, both already discovered and newly discovered, you should follow these steps:

1.Navigate to the device details in CPDI.

2.Select the option to reclassify the device.

3.Create a user rule based on the desired attributes of the device.

4.Choose the "Save & Reclassify" option.

This process ensures that the device is reclassified according to the new custom type and that the rule is applied to all existing and future devices with matching attributes, maintaining consistent classification across the network.

Comprehensive Detailed Explanation

The configuration includes the command aaa authentication allow-fail-through, which specifies that if the TACACS+ server fails to respond (e.g., times out), the switch will proceed to the next authentication method in the sequence, which is local. In this scenario:

The switch first attempts to authenticate the user against the TACACS+ server.

When the TACACS+ server fails to respond, the switch falls back to local authentication.

The user netadmin is a local account configured on the switch and belongs to the operators group.

As a result, the user is successfully authenticated locally and is granted operator level access.

TACACS+ fallback behavior for HPE Aruba switches.

When an AOS-CX switch implements User-Based Tunneling (UBT) to a cluster of three HPE Aruba Networking gateways, the switch determines to which gateway to tunnel each user's traffic based on the particular gateway assigned as that user's active user designated gateway. This ensures that traffic is efficiently distributed and managed according to the designated gateway for each user.

1.User Designated Gateway: Each user's traffic is tunneled to a specific gateway that has been designated for that user, ensuring efficient handling of traffic.

2.Traffic Distribution: This method allows for balanced distribution of user traffic across multiple gateways, enhancing network performance and reliability.

3.Gateway Assignment: The switch uses the assigned gateway for each user to determine the tunneling path, ensuring that traffic is directed to the appropriate gateway.

To capture only the traffic sent in the mirroring session between an AOS-CX switch and a management station running Wireshark, you should apply a capture filter that isolates the specific traffic of interest. In this case, using the filter udp port 5555 will capture the traffic associated with the mirroring session. This is because AOS-CX switches typically use UDP port 5555 for mirrored traffic, ensuring that only the relevant mirrored packets are captured and excluding other traffic generated by the management station.
