Why a Mirror Session Is the Correct Choice

To analyze a wired client’s traffic with Wireshark, you need the traffic mirrored to your management station where Wireshark is installed. The most effective way to achieve this is by configuring a mirror session on the AOS-CX switch, specifying the client port as the source and your management station as the destination.

Analysis of Each Option

A. Access the client's switch's CLI from your management station. Access the switch shell and run a TCP dump on the client port:

Incorrect:

AOS-CX switches do not natively support packet capture (e.g., tcpdump) directly on the switch CLI.

This approach is not feasible for capturing and analyzing live client traffic.

B. Go to the client's switch in HPE Aruba Networking Central. Use the "Security" page to run a packet capture:

Incorrect:

HPE Aruba Networking Central provides security insights but does not directly support initiating packet captures for detailed analysis.

Traffic analysis with tools like Wireshark requires local packet capture at the management station.

C. Set up a policy that implements a captive portal redirect to your management station. Apply that policy to the client's port:

Incorrect:

Captive portals are designed for user authentication and redirection, not traffic analysis.

This would disrupt the client’s network activity without enabling traffic analysis in Wireshark.

D. Set up a mirror session on the client's switch; set the client port as the source and your station IP address as the tunnel destination:

Correct:

Mirroring the client port to your management station is the standard method for analyzing live network traffic with Wireshark.

Steps include:

Configure a mirror session on the client’s AOS-CX switch.

Set the client’s port as the source.

Set your management station as the destination using its IP address (via GRE tunnel or physical interface).

Start capturing traffic with Wireshark on the management station.

Final Recommendation

To analyze the client's traffic, configure a mirror session on the switch, set the client port as the source, and direct the traffic to your management station where Wireshark is running.

When using OpenSSL to obtain a certificate signed by a Certification Authority (CA), you should submit the Certificate Signing Request (CSR) file, which is file1.pem, to the CA. The CSR contains the information about the entity requesting the certificate and the public key, but not the private key, which is in file2.pem. The CA uses the information in the CSR to create and sign the certificate.

1.CSR Submission: The CSR (file1.pem) includes the public key and the entity information required by the CA to issue a certificate.

2.Private Key Security: The private key (file2.pem) should never be sent to the CA or shared; it remains securely stored on the requestor’s server.

3.Certificate Issuance: After the CA signs the CSR, the resulting certificate can be used with the private key to establish secure communications.

Access to the Onboard portal is controlled by a dedicated Pre-Auth service in ClearPass Policy Manager:

The “ClearPass Onboard Service Pre-Auth” service defines which authentication sources (e.g., AD domain, local DB, guest) are used when users log into the Onboard web portal.

To restrict access to domain users only, you edit this Pre-Auth service to use only the Active Directory auth source (and appropriate authorization checks, such as group membership).

Exam and configuration references for ClearPass Onboard clearly identify the Onboard Pre-Auth service as the place where you control who can log into the Onboard portal.

Network Settings and Provisioning profiles in Onboard govern SSID, profiles, and device configuration, not portal user authentication.

The 802.1X services for wireless control network access after onboarding, not login to the onboarding portal itself.

Therefore, to limit the portal to domain users, you should edit the ClearPass Onboard Service Pre-Auth service on CPPM → Option B.
